This light-curing active baseliner is the ideal one-component underfilling material for composite, ceramic and amalgam restorations. Its active chemistry compensates for the shrinkage typical with composite fillings, prevents crack formations, and, with that, post-operative sensitivities, and minimizes microfractures and secondary caries. The material is radiopaque, provides long-term fluoride release, and, due to its zinc content and special monomers, has antibacterial properties. Ionosit-Baseliner – for stress-free restorations. Indicated for use as a base material for composite, amalgam and ceramic restorations. Ionosit Baseliner can also be used for blocking out undercuts and pulp capping. Lining has never been easier or more reliable Ionosit Baseliner is applied in a thin layer between the dentine and composite. It reacts with the dentine and forms a tight marginal seal between the dentine and the Ionosit, preventing post operative sensitivity.

Many variables can affect the final outcome of a resin restoration: the technical difficulty of the restoration, the quality of the preparation, and the resin composite materials chosen, to name a few. The impact on the longevity of the restoration that a curing light can have is often overlooked, but choosing the correct curing light is essential. In a recent study1, the following factors were identified as the most critical factors affecting direct restorative success: 1. Proximity to the restoration Direct access to the restoration allows the maximum amount of the curing light’s energy (emitted light) to better reach and polymerize light-cured materials. VALO’s 5°, slender head design ensures complete and direct access to achieve this maximum cure. VALO Competitor’s contraangle light guide. 2. The type of light emitted from the curing light Science has supported the use of curing lights with broad spectrum wavelengths that cure all light-cured dental materials. Numerous curing lights on the market fail to include multiple wavelengths or simply don’t achieve uniform irradiance of their multiple wavelength LEDs. VALO’s proprietary, 4-color LED pack offers even dispersion and the most uniform, multiwavelength light available in an LED curing light, to ensure a complete final cure. 3. The amount of energy actually delivered to the resin Manufacturer’s claims give us a general idea of what different curing lights may be capable of, but in most cases technique, proximity, true clinical environments, and even the type of resin being used can affect the amount of energy that is effectively delivered to cure the resin. VALO’s accessibility, along with its efficiently delivered high power modes result in the required amount of energy delivered to the resin for complete curing, within the shortest amount of time. “Undercuring the resin adversely affects its physical properties, reduces bond strength, increases marginal wear and breakdown, decreases biocompatibility, potentially increases DNA damage resulting from leachates and increases bacterial colonization of the resin. Equally undesirable is the delivery of too much energy to the tooth, which may cause thermal damage to the pulp and exposed oral tissues. Therefore, it is essential to establish a method for accurately quantifying the energy delivered by a curing light to a dental restoration under clinically relevant conditions. It would then be possible to determine the effects of operator technique, choice of curing light and position of the estoration on the amount of energy that the resin actually receives.”1 1.

Mandikos BDSc, MS, Cert Pros, FRACDS, FICD Preparing crown margins that are defined, continuous and of the proper depth and position is a significant daily challenge in fixed Prosthodontics. However, once these margins have been formed, capturing the margins with high fidelity in an elastomeric impression can be just as challenging. A survey conducted by Gordon Christensen which was published in the Journal of the American Dental Association1 reported that the most frequently reported problem encountered by Laboratory Technicians doing fixed Prosthodontics, was the poor quality of the impressions. Subsequent studies have reported that the prevalence of poor quality impressions for fixed Prosthodontic procedures is widespread and of significant concern.2,3. There are many factors that contribute to inaccurate impressions; however the most observable problem would appear to relate to accuracy of capture of the margin finish line.4 The margins of a crown preparation can be difficult to capture in an impression due to inadequate soft tissue retraction, or due to moisture or poor control of bleeding. Retraction cords have traditionally been the preferred means of achieving both tissue retraction and haemostasis. A survey of over 1200 members of the American College of Prosthodontists (all specialist Prosthodontists) revealed that 98% used retraction cord. Of those using cord, 81% soaked it first in a haemostatic solution, and of those who soaked their cord, 55% used Aluminium Chloride.5 place, and similarly fine placement instruments are required. The cord should horizontally retract the tissue, not displace it vertically. Practice is needed to allow the clinician to rotate and roll the cord as it goes into the sulcus and the cord must remain in the sulcus for in excess of 10 minutes to achieve effective retraction and haemostatic control. This complicated and time consuming process has allowed the introduction and adoption of alternative, cord-less retraction techniques. Expanding polyvinyl siloxane and Kaolin based paste materials have been introduced to the market with claim of faster, easier and more effective retraction. A recent study has even hinted that these materials may be more efficient to use, as they were much less likely to stimulate bleeding in the gingival sulcus either during placement, or immediately after removal, when compared to retraction cord.6 The following case report describes the use of a new material “Traxodent®” from Premier®. Traxodent is a clay-based paste which contains 15% Aluminium Chloride. The paste is delivered to the sulcus directly from its syringe as an alternative to use of a separate haemostatic solution and retraction cord. It can be used alone for haemostasis, or in combination with Premier’s “Retraction Caps” if greater retraction is desired. It is recommended to leave the paste in place for 2 minutes prior to rinsing it away. Placing a retraction cord is a deliberate procedure with the aim being to place it at the level of the preparation, and within the confines of the gingival sulcus. Finer, braided cords are easier to Traxodent’s ergonomic disposable syringe and bendable syringe tip provides excellent reach.

The patient was referred to an Endodontic colleague and the #45 was subsequently root canal treated. (Figures 1 to 3). Author Michael N. Mandikos BDSc, Cert Pros, FRACDS, FICD Dr. Mandikos is a registered specialist in Prosthodontics. He received his 1. 2. 3. After root canal treatment, the tooth was restored with a direct post and core, and then prepared for a Lava zirconia crown. The extent of the caries meant that the distal margin was located very deep and in a subgingival position. This resulted in significant bleeding as “gingival curettage” was performed by the preparation bur. (Figures 4 and 5).

Approximately 4 weeks later, the patient returned for insertion of the definitive crown. At this appointment, the soft tissues were observed to have healed very nicely, with no residual inflammation and no recession. The crown was adjusted and seated, and the procedure was performed in a healthy gingival environment. (Figures 11 and 12.). 4 weeks later! Vision 11. 12.

In particular, when necessity has meant margins are placed very subgingivally or electrosurgery has been performed, I have observed Traxodent to work very quickly and effectively in controlling the bleeding in these instances. The six images below demonstrate an upper right first premolar (#14) that lost its palatal cusp through fracture, nearly 3mm subgingivally. A combination of electrosurgery and tooth preparation created a significant amount of bleeding, which was then arrested by the application of Traxodent for 2 minutes. After rinsing the Traxodent away, the clean, dry tissue surface then facilitated an accurate impression, for the fabrication of a gold post and core. The final crown was subsequently made and cemented to place.

Just like the original, reliable Luxatemp the remarkable features of the material are its very easy handling and a consistency in quality. Important material properties are; minimal shrinkage, high flexural strength, and good abrasion resistance (most important for temporary bridges), biocompatibility and a maximum setting temperature of 38ºC. This effectively excludes an iatrogenic irritation of the pulp (hyperaemia at 39ºC, necrosis at 42.5ºC). A 46-year-old patient: After periodontal treatment with complete curettage, a prosthetic treatment plan for the mandibular is made. Among other things, an 8year-old difficient bridge (35-37) has to be restored. 35 shows a well preserved root filling and can be used as an abutment because of its healthy periodontal situation. The improved safety cartridge system with separate outlet-openings for base and catalyst guarantees that these pastes only come into contact inside the mixing tip. With this, premature setting and inhomogeneous mixing of the material are avoided. The colour stable and highly polishable Luxatemp Star is available in six shades (A1, A2, A3, A3.5, B1 and Bleach Light). Procedure An impression is taken with LuxaForm, a thermo-plastic impression polymer that is quick and easy to use. One disk per tooth is put into ~ 70ºC warm water. The material reaches its workable state after only one minute. The transition can be easily monitored by the colour change of the material from blue to transparent. In combination with Luxatemp Glaze & Bond, which can also be used for repairing an older provisional, the surface can be sealed fast and effectively; small irregularaties can be compensated for and at the same time the surface is provided with a smooth and very shiny appearance. High gloss polishing is no longer necessary. The result is a highly aesthetic temporary restoration with reduced possibilities of plaque accumulation and an increased protection against straining. LuxaForm is a thermoplastic impression polymer delivered in the form of small disks. The easy and time saving handling of this innovative and smart product concept is impressive, an important advantage with regards to impression materials for provisionals, especially as compared with the normally used alginates are, for example, the long term dimensional stability. Therefore the re-making of a new provisional in case of breakage or loss is very easy. Patients are more comfortable with a quick impression using LuxaForm. LuxaForm is limited to the immediate preparation area rather than having to have a full impression made. Also the shorter time period in the mouth is more patient-friendly. Vision In the meantime, undercuts, in this case the pontic area, can be blocked out with wax after the gingiva is blown dry. A small cube is formed out of the soft thermoplastic material and modeled around the teeth to be reproduced (recommended not to use gloves). In a few seconds, the material will regain its original opacity and can be easily removed from the mouth. After removing the existing bridge, excavation of caries, placement of build-ups and final preparation, retraction aids are placed. A two-viscosity impression is taken with Silagum as heavy body and Prosthodontics phone: 1800 025 300 fax: 1800 025 202 www.gunz.com.au The technology behind beautiful temporaries Fig 1: Status Fig 2: LuxaForm in its plastic state Fig 3: Solidified LuxaForm Fig 4: Filling of LuxaForm impression Fig 5: Cured temporary Fig 6: Final temporary in place Honigum-Automix Light as wash material. Like no other A-silicone, HonigumAutomix Light has an extremely good penetration into the sulcus and reproduces precisely even the finest details. Now the temporary restoration is made. The wax blockout can be removed very easily from the impression. The LuxaForm impression is isolated slightly with Vaseline before filling it with Luxatemp Star. Luxatemp Star application is made with the mixing tip touching the occlusal surface of the matrix and allowing Luxatemp Star to flow up to the top of the LuxaForm impression. The mixing tip has to stay immersed in the material, to avoid inclusion of air bubbles. 45 seconds is available for this procedure. Impression is reseated onto the dried abutments and allowed to set. No longer than 2 to 3 minutes after beginning of mixing, the impression is removed from the mouth. At this moment Luxatemp Star is in its rubbery phase. Because the material bonds to itself in this state, you may now, if necessary, reinforce the walls or extend the margins by adding additional Luxatemp Star. Three minutes after removal from the mouth the temporary restoration has set and can be finished with slow-speed acrylic burs and disks. Finally, the surface is sealed with Luxatemp Glaze & Bond. Luxatemp Glaze & Bond is applied unit-by-unit in thin layers and light-cured for 20 to 40 seconds. The finished temporary restoration can now be seated using a temporary cement, in this case TempoCem us used After a 45 second setting time excess cement can be easily removed. Luxatemp Star & Luxaform: Advantages • Reliable dimensional stability • Time saving with tray less, local impression Benefits • Increased patient comfort especially in small mouth or gag sensitive patients The application of Luxatemp Star Plus in combination with Luxaform demonstrates that a shorter working time and the fabrication of a temporary restoration of superior quality are absolutely compatible. Conclusion This report describes an effective combination of a whole product family. Luxatemp Star guarantees consistently high quality and reproducible working results with Luxatemp Glaze & Bond, a conventional polishing procedure is eliminated.

Rev. 1918; 32: 175-191. Let’s face it - How many times have you felt like “pulling your hair out” because of a stubborn lower denture problem? You’ve checked the base adaptation, the border seal, neutral zone and the frenum attachment and all are fine, yet the denture keeps lifting up! Even worse, the resorbption of the alveolar process can be so severe as to make virtually impossible the construction of stable, satisfactory dentures. There are many ways to approach each of these problems: Alveolar ridge augmentation, Vestibuloplasty, Implant supported overdenture to name a few. Often these recommendations are dismissed by patients due to the fact they fear having the procedure done or just plain can’t afford it. Service Key (Gauge) Valve Processing Cap How do we define denture retention? Denture retention is, by definition, resistance of a denture to vertical movement away from the tissues. In light of current developments and the understanding of material science and physics, there is a general acceptance among clinicians that denture retention is dependent on the control of the flow of interposed fluid and its viscosity and film thickness. Surface action tension forces at the periphery, contribute to retention, but most important are a good base adaptation and a border seal. However, at the first displacement, which is inevitable at some point, a gap opens along the border seal, consequently reducing the resistance to vertical movement and subsequently lifting up the denture. Introducing NEW Ultra Suction unidirectional valves for dentures Diaphragms Features at a Glance • Offers patients an affordable solution to problem dentures • Together with the physical mechanisms of denture retention, will improve considerably the stability of your patients’ dentures • When mounted on an upper denture will help patients reduce the size of the plastic palate, improving both phonetics and taste. • Ultra Suction Kit contains everything you need to fit 1 denture – no inventory issues Ultra Suction is a specially designed set of unidirectional valves and profile bar capable of remodelling the alveolar ridge, thus creating and maintaining a seal around this area. Once the denture is in place and in tight occlusion (firm bite), the gingival tissues penetrate the suction chamber. The air is expelled through the valves. The diaphragms prevent its re-introduction. The pressure difference (lower pressure beneath the denture), exerts a pull and seals off the new alveolar ridge periphery. At the first attempt to swallow, the vacuum created in the mouth eliminates any air left in the suction chamber. The result - a better fit to the tissues and an improved resistance to dislodging forces. Ultra Suction can be easily incorporated into new dentures and relines by dentists and dental technicians alike. Each Ultra Suction kit contains everything required to fit Ultra Suction to a single upper or lower denture arch.

The objectives are to remove all the pulp tissue, bacteria and their byproducts while providing adequate canal shape to fill the canal. E Traditionally, the shaping of root canals was achieved by the use of stainless steel hand files. However, techniques using stainless steel hand files have several drawbacks: 1. They require the use of numerous hand files and drills to adequately prepare the canals (Schilder 1974). 2. Hand instrumentation with stainless steel files is time consuming (Ferraz et al. 2001). 3. The stainless steel hand instrumentation techniques have an incidence of canal transportation (Kuhn et al. 1997, Reddy & Hicks 1998, Ferraz et al. 2001, Pettiette et al. 2001). 4. Finally, from a clinical standpoint, the use of hand instruments in narrow canals can be very frustrating especially in teeth with difficult access. 2001). However, as these techniques also require the use of numerous instruments to enlarge the canal to an adequate size and taper, they are relatively time consum-ing. Also, the use of hand instruments (for example to create a glide path prior to using a rotary instrument), which can be very frustrating in narrow canals in teeth with a limited access, is required. The purpose of this article is to introduce a new concept for canal preparation, a paradigm shift. The canal preparation is accomplished using only one specifically designed nickel-titanium engine-driven instrument used in reciprocation and without prior hand filing, which means hand files are not used to enlarge the canal prior to using the reciprocating file. This new concept is a paradigm shift because it goes completely against the current teaching standard, which requires the gradual enlargement of the canal with different files/instruments until the desired shape is obtained. Only one instrument, the reciprocating instrument, is needed to enlarge the canal, even a narrow and curved canal, to an adequate size and taper. However, there are some exceptions that will be discussed later in this article. Nickel-titanium (NiTi) hand or rotary instruments are also used to achieve the mechanical objectives of the canal preparation. NiTi instruments offer many advantages over conventional stainless steel files. They are flexible (Walia et al. 1988), have increased cutting efficiency (Kazemi et al. 1996) and have improved time efficiency (Ferraz et al. 2001). Furthermore, NiTi instruments maintain the original canal shape during preparation and have a reduced tendency to transport the apical foramen (Kuhn et al. 1997, Reddy & Hicks 1998, Ferraz et al. 2001, Pettiette et al. This new concept is also a paradigm shift because it goes completely against the current teaching standard, which requires the creation of a glide path with smaller instruments prior to using a shaping instrument to minimize the incidence of fracture. A glide path is no longer a pre-requisite with this new concept of canal preparation. This article also introduces the notion of the “path of least resistance”. The shaping instrument will follow the existing and natural path of least resistance, which is the canal. This is Endodontics phone: 1800 025 300 fax: 1800 025 202 www.gunz.com.au One File Endo: A New Concept not only time-saving but also particularly convenient in teeth with limited access. Additionally, errors associated with the use of hand filing prior to using mechanically driven instruments can be avoided. Fig.1 R25 R40 R50 Fig. 2 RECIPROC® Paper Points The first and only paper on the use of only one engine-driven instrument in reciprocation to prepare a root canal was published in the International Endodontic Journal (Yared 2008). The article described the use of an F2 ProTaper instrument. However, the use of that instrument in reciprocation presented two drawbacks: 1. Instrument fracture by cyclic fatigue in relation to the relative rigidity of the instrument due to its size, taper and cross-section (Pruett 1997). 2. The necessity of creating a glide path with additional hand files prior to using the F2 instrument in reciprocation. The clinical impression was that the F2 instrument does not cut efficiently enough into a narrow and uninstrument ed canal. Frequently, it did not advance in the canal without a glide path. Other rotary instruments were also tested in a single file preparation technique. Issues similar to those encountered with the use of the F2 were observed (unpublished results). An ATR Vision motor (ATR, Pistoia, Italy) was used with the F2. This motor is no longer manufactured. Fig. 3 RECIPROC® Gutta-Percha For these reasons, a new system for single file reciprocation without prior use of hand files was developed (VDW GmbH, Munich, Germany). The system includes three instruments, the RECIPROC® instruments (R25, R40 and R50) (Fig.1), a motor (VDW.SILVER® RECIPROC®) (Fig. 5), matching paper points (Fig. 2) and gutta-percha cones (Fig. 3). Only one RECIPROC® instrument is used for the canal preparation depending on the initial size of the canal. The instruments are made from an M-Wire nickel-titanium that offers greater flexibility and resistance to cyclic fatigue than traditional nickel-titanium. They have an Sshaped cross-section (Fig. 4). The three instruments have a regressive taper. Fig. 4 RECIPROC® cross-section • The R25 has a diameter of 0.25 mm at the tip and an 8% (0.08 mm / mm) taper Vision phone: 1800 025 300 Fig. 5 VDW.SILVER® RECIPROC® over the first 3 mm from the tip. The diameter at D16 is 1.05 mm. • The R40 has a diameter of 0.40 mm at the tip and a 6% (0.06 mm / mm) taper over the first 3 mm from the tip. The diameter at D16 is 1.10 mm. • The R50 has a diameter of 0.50 mm at the tip and a 5% (0.05 mm / mm) taper over the first 3 mm from the tip. The diameter at D16 is 1.17 mm. The motor is battery operated. The battery is rechargeable and the motor can be used while the battery is charging. The instruments are used at 10 cycles of reciprocation per second, the equivalent of approximately 300 rpm. The motor is programmed with the angles of reciprocation and speed for the three instruments. The values of the CW and CCW rotations are different. When the instrument rotates in the cutting direction it will advance in the canal and engage dentine to cut it. When it rotates in the opposite direction (smaller rotation) the instrument will be immediately disengaged. The end result, related to the degree of CW and CCW rotations, is an advancement of the instrument in the canal. Consequently, only very light apical pressure should be applied on the instrument, as its advancement would be almost automatic. These angles are specific to the RECIPROC® instruments. They were determined using the torsional properties of the instruments and are influenced by specific features related to the motor such as torque. The technique is extremely simple. In the majority of canals, only one RECIPROC® instrument is used in reciprocation to complete the canal preparation and there is no need for hand filing. The access cavity requirements, the Endodontics fax: 1800 025 202 www.gunz.com.au One File Endo: A New Concept straight-line access to the canals and the irrigation protocol are the same as for standard preparation techniques. It is not necessary to widen the root canal orifice with a Gates Glidden drill or an orifice opener. • Selection of the appropriate RECIPROC® instrument (Fig. 6) Selection of the RECIPROC® instrument is based on an adequate pre-operative radiograph. If the canal is partially or completely invisible on the radiograph, the canal is considered narrow and the R25 is selected (Fig. 7). In the other cases, where the radiograph shows the canal clearly from the access cavity to the apex, the canal is considered medium or wide (Fig. 8). A size 30 hand instrument is inserted passively (with a gentle watch winding movement but without filing action) to the working length. If it reaches the working length, the canal is considered large; the R50 is selected for the canal preparation. If the size 30 hand file does not passively reach working length, a size 20 hand file is inserted passively to the working length. If it reaches working length, the canal is considered medium; the R40 is then selected for the canal preparation. If the size 20 hand instrument does not reach the working length passively, the R25 is selected. Fig. 7 Canal is considered narrow: R25 Fig. 6 Selection of the appropriate RECIPROC® instrument Fig. 8 Canal clearly visible from access cavity to apex: considered medium or wide (R50 was used for the canal preparation; an increased apical enlargement was obtained with a size 70 hand file) • Preparation step by step (without creating a glide path) In reciprocation, clockwise and counterclockwise angles determine the amplitude of reciprocation, the right and left rotations. These angles are lower than the angles at which the RECIPROC® instrument would usually fracture (if bound). When a reciprocating file binds in the canal, it will not rotate past its specific angle of fracture. Therefore, the creation of a glide path to minimize binding is not required for the RECIPROC® instruments. The cutting efficiency of the RECIPROC® instruments and the centring abil-ity associated with reciprocation (Hata et al. 2002, Song et al. 2004) allow the instruments to enlarge uninstrumented and narrow canals in a safe manner. Before commencing preparation, the length of the root canal is estimated with the help of an adequately exposed and angulated pre-operative radiograph. The silicone stopper is set on the RECIPROC® instrument at 2/3 of that length. The RECIPROC® instrument is introduced in the canal with a slow in-and-out pecking motion without pulling the instrument completely out of the canal. The amplitude of the in- and out-movements should not exceed 3-4 mm. Only very light pressure should be applied. The instrument will advance easily in the canal in an apical direction. After three in- and out- movements, or when more pressure is needed to make the instrument advance further in the canal, Endodontics phone: 1800 025 300 fax: 1800 025 202 www.gunz.com.au One File Endo: A New Concept or when resistance is encountered, the instrument is pulled out of the canal to clean the flutes. A #10 file is used to check patency to 2/3 of the estimated working length. The canal is copiously irrigated. The RECIPROC® instrument is used until it has reached 2/3 of the estimated working length as indicated by the stopper on the instrument. The instrument is then removed from the canal, the canal is irrigated and a #10 file is used to determine the length. The RECIPROC® instrument is then re-used in the same manner until the working length has been reached. As soon as the working length has been reached, the RECIPROC® instrument is withdrawn from the canal. The RECIPROC® instrument can also be used in a brushing motion against the lateral walls of wide canals. Fig. 9 Glide path was created in the DB canal • Creating a glide path during the use of the RECIPROC® instruments: indication and management (Fig. 9) With continuous rotary NiTi systems it is necessary to create a glide path in order to minimize the risk of fracture (Peters et al. 2003, Yared et al. 2004, Patino et al. 2005). During the use of a rotary instrument, the tip of the in-strument may bind in the canal. The motor will keep rotating the instrument while the tip of the instrument is bound. The instrument will rotate past its plastic limit and will eventually fracture at a specific angle of rotation. For this reason, it is necessary to create an initial glide path, or a minimal canal enlargement, before using continuous rotary instruments. The glide path will minimize the incidence of instrument binding and, therefore, minimize the risk of fracture. Just as with any continuous rotary NiTi system, it is also possible to use the RECIPROC® reciprocating file after creating an initial glide path with hand instruments to a size 10 or 15. A glide path may also have to be created in some canals when the RECIPROC® instrument stops advancing in the canal or if advancement becomes difficult. In this case, pressure should not be exerted on the RECIPROC® instrument. The instrument should be removed from the canal, and the canal irrigated. If the RECIPROC® instrument still advances with difficulty or if it does not advance, it should be removed from the canal and the canal irrigated once again. At this point, hand files #10 and 15 should be used to create a glide path to the working length. The RECIPROC® instrument would then be used until the working length has been reached. If, however, the progress of the RECIPROC® instrument is still difficult or not possible, the canal preparation would need to be completed with hand files. Fig. 10 Abrupt apical curvature • Using hand files to finish the apical canal preparation In some canals, the #10 file used for the working length determination (after the RECIPROC® instrument has reached 2/3 of the estimated working length) has to be precurved, otherwise it cannot reach working length. This indicates the presence of an abrupt apical curvature (Fig. 10). The use of the RECIPROC® instruments is contra-indicated in this instance. The canal preparation has to be finished with hand files. However, in most of the cases, the size 10 file used for the working length determination will reach that length without being pre-curved (indicating the presence of a gradual curvature) (Fig. 11). The RECIPROC® instrument will be used to working length to complete the preparation. Fig. 11 Gradual curvature. Size 10 file used for the working length determination will reach working length without being pre-curved Vision phone: 1800 025 300 • Increased apical enlargement (Fig. 8) In some canals an increased apical enlargement (based on gauging the canal, for example) may be required. A larger RECIPROC® instrument or a hand instrument may be used for this purpose following the R25 and the R40, and a hand instrument is used following the R50. Endodontics fax: 1800 025 202 www.gunz.com.au One File Endo: A New Concept Additional advantages of the RECIPROC® concept and instruments • Centring ability Preliminary evidence has demonstrated the centring ability of the reciprocating instruments used according to this concept (unpublished results). Figures 12 and 13 show severely curved canals prepared with the R25 without the creation of a glide path. The radiographs show that the canal curvature was maintained despite the severity of the curvature. • Safety A rotary instrument can also fracture if it binds in the canal, especially at its tip. When using a rotary system the tip of the instrument may bind in the canal; the motor will keep rotating the instrument while its tip is bound and the instrument will eventually fracture at a specific angle of rotation. In reciprocation, clockwise and counterclockwise angles determine the amplitude of reciprocation, the right and left rotations. These angles, stored in the motor, are significantly lower than the angles at which the instrument would usually fracture. If the instrument binds in the canal, it will not fracture because it will never reach the angle at fracture. In this respect, single file reciprocation is safer than rotary techniques because fracture by binding (fracture by taper lock or torsional fracture) is eliminated. Fig. 12 One RECIPROC® instrument replaces several hand and/or rotary instru-ments for a canal preparation procedure. Therefore, the RECIPROC® instrument is subjected to cyclic fatigue and should be discarded after the completion of a case. The plastic band on the handle of the instrument deforms if the instrument is autoclaved; this safety feature eliminates fatigue fracture due to repeated use in more than one case. • Shorter working time Working time was four times faster with the single file reciprocation in comparison with a NiTi rotary preparation technique (unpublished results). • Faster learning 92% of RECIPROC® users were able to prepare three canals consecutively without errors compared to 30% of the continuous rotary NiTi system users (unpublished results). • Less procedural errors A lower incidence of complications such as canal transportation, ledging and blockage was observed with the single reciprocation technique than with a major rotary technique (unpublished results). Fig. 13 Severely curved canals prepared with the R25 without the creation of a glide path • Elimination of cross-contamination between patients The clinician is faced with a major concern when considering the useof NiTi rotary instruments: the possibility of cross-contamination as-sociated with the inability to adequately clean and sterilize endodonticinstruments (Spongiform Encephalopathy Advisory Committee 2006).A recent study found prions in human pulp tissue (Schneider et al. 2007). Tooth structure and organic debris were observed on the surface of NiTi rotary instruments, and appeared to adhere in the surface cracks despite meticulous ultrasonic cleaning and decontamination (Alapati et al. 2003, 2004, Sonntag & Peters 2007). Therefore, the single use of endodontic instruments was recommended to reduce instrument fatigue and possible cross-contamination. However, the single use of endodontic instruments and, mainly the more expensive NiTi rotary instruments, may become an economical burden on the endodontist and the general dentist especially as the available techniques involve the use of at least three to four NiTi rotary instruments. Consequently, the introduction of this new concept for the canal preparation technique, which reduces the number of instruments required to achieve the mechanical and bio- Endodontics phone: 1800 025 300 fax: 1800 025 202 www.gunz.com.au One File Endo: A New Concept logical objectives, is beneficial. The instrument is discarded after each case; cross-contamination among patients is eliminated and cross-contamination involving the staff is mini-mized because the assistant(s) will discard the instrument immediately after completing the case instead of manipulating the instrument to clean it. Gutta-percha filling material can be easily removed from the canal with the R25. First of all, the bulk of the gutta-percha in the coronal third of the canal should be removed with an appropriate instrument (e.g. electric heat carrier, ultrasonic tip). A solvent (e.g. eucalyptus oil) is used as required and the R25 is used as described above until working length has been reached. If resistance is encountered, pressure should not be applied. The instrument should be removed from the canal, the solvent replaced and the R25 used again. Fig. 14 After reaching working length with the R25, the R40 or R50 can be used for an increased apical enlargement, as necessary. RECIPROC® instruments can also be used in a brushing motion against the lateral walls of the canal to remove any residual filling material. Carrier-based obturators can be removed in the same manner as gutta-percha filling material. The carrier may be removed in one piece during the use of the RECIPROC® instrument; otherwise, it will be removed in small pieces with the gutta-percha.

Many factors, including dietary habits (drinking coffee, tea, soda, and red wine) and certain medications, affect the whiteness of your smile. Tooth whitening is an affordable and effective way to combat common causes of tooth discoloration, while boosting your self-confidence and improving your appearance. You already know that whitening works, but do you know how? Stains on teeth can be classified in one of two ways: extrinsic or intrinsic. Extrinsic stains can be removed with whitening toothpaste or a good prophylactic dental cleaning. Intrinsic stains live between the micro-cracks in your enamel and deep within your dentin; only tooth whitening agents can remove those. Tooth whitening agents, like carbamide peroxide or hydrogen peroxide, penetrate the prisms in your enamel to get to discoloured molecules. Oxygen molecules from the bleaching agents react with the discoloured molecules, breaking the bonds that hold them together. By changing their chemical make-up, the oxygen molecules affect the way the discoloured molecules reflect light and display colour. The once discoloured molecules now reflect a brighter, whiter appearance.1 Hydrogen Peroxide vs. Carbamide Peroxide: What’s the Difference? Some whitening products contain hydrogen peroxide and others contain carbamide peroxide. So what’s the difference? What is the difference between hydrogen peroxide and carbamide peroxide? Carbamide peroxide is composed of hydrogen peroxide and urea, with the hydrogen peroxide constituting 1/3 of the total peroxide concentration. For example, a product with 30% carbamide peroxide has about 10% hydrogen peroxide. Does one work better than the other? No! The good news is that hydrogen peroxide and carbamide peroxide both produce the same outstanding results. A study published in JADA showed that while carbamide peroxide appeared to produce slightly more dramatic results at first, ultimately, products containing equivalent amounts of carbamide peroxide and hydrogen peroxide produced exactly the same results.2 Does one work faster than the other? Yes and No. Hydrogen peroxide breaks down faster than carbamide peroxide. It releases most of its peroxide within 30–60 minutes. Carbamide peroxide, on the other hand, releases about 50% of its peroxide in the first two hours and can remain active for up to 6 additional hours.3 This means that products using hydrogen peroxide have shorter wear times. However, the number of days the patient will need to wear each depends not on Tooth Whitening phone: 1800 025 300 fax: 1800 025 202 www.gunz.com.au Opalescence®: The Whiter Smile ... BEFORE Both Hydrogen Peroxide and Carbamide Peroxide Produce Excellent Results AFTER hydrogen peroxide vs. carbamide peroxide, but on the individual’s unique needs and rate of tooth colour change. Does one cause more sensitivity? No. There is no noticeable difference in sensitivity, regardless of whether you are using a hydrogen peroxide or carbamide peroxide product. This was also noted in the same JADA study that showed hydrogen peroxide and carbamide peroxide produced equally brilliant results. You can feel great about recommending either a hydrogen peroxide or a carbamide peroxide product to your patients. Both will produce the same high quality results, with no difference in sensitivity or rebound. Opalescence has developed a complete line of carbamide peroxide and hydrogen peroxide whitening product to fit every patient with any lifestyle. Does one cause more rebound? No. Rebound has more to do with dehydration than peroxide levels. Whitening gels like Opalescence that contain higher water content help to prevent rebound caused by dehydration. Does one have a longer shelf life? Yes. Products with carbamide peroxide have a slightly longer shelf life than those with hydrogen peroxide, although when refrigerated, all peroxide products have an increased shelf life. This chart lists the Opalescence products, the amount of hydrogen peroxide or carbamide peroxide in each, and their respective wear times and shelf life.

Dr Geoffrey Wexler “There are three different treatment areas in Equipment phone: 1800 025 300 fax: 1800 025 202 www.gunz.com.au Practice Redevelopment: Creating a Specialist’s Dream all. We have open plan space with three chairs and a lot of family seating for treating younger patients; two private treatment rooms for adults that are separated by the sterilisation area; and a third private area set up for new patient examinations and photography.” Dr Wexler purchased all new equipment for the practice from Gunz Dental including six Belmont dental chairs. “We bought five Belmont Clesta II dental chairs for the open plan area and the private rooms and a Belmont Clair Clesta II ‘knee break’ chair for the new patient area, plus ceiling mountedlights,” he said. “We then chose Beaverstate equipment, also from Gunz, for the delivery systems which are concealed in the cabinetry and slide out when required. “I was a paediatric dentist before I was an orthodontist and I’ve never liked over-thechair delivery systems as it is very intrusive on the patient’s space. So the idea was to conceal all the equipment as much as possible and eliminate clutter.” Dr Wexler said that the increase from two to six chairs hasmade the work environment far less stressfull. “Stress often comes from keeping people waiting so I now work with two oral health therapists which has increased our clinical capacity and we have more chairs to use which allows us to meet our promise of keeping to schedule.
