SUTvirviARY
The dental treatment needs of adults in Kenya are high but the demand for dental services
remains very low. Some people ignore these ailments and only seek treatment when they
experience pain. Few of them do not seek treatment, not by choice, but due to lack of
money to address their problems.
This descriptive cross sectional study will be conducted on any patient attending the oral
diagnosis clinic. A total of 132 patients aged 18 years Andover will be selected to the
study. Systematic random sampling method will be used. A clinical examination form
will be used to record data.
Data collected will be analyzed with a computer using the SPSS program. Descriptive
statistical tests will be carried out to explain the frequency of various variables. The chi
square tesr will be used to determine the relationship between categorical variables. Data
will then be presented in tables, bar graphs and pie charts.
The information obtained from the research could be used to formulate policies that will
best address the treatment needs of adult patients visiting the university dental hospital.
The research project is also to satisfy the requirements
for the
undergraduate degree
course in dental surgery.

INTRIODUCTION
Treatment needs generally refer to professionally determined or normative needs related
to the presence of disease. Although
most dental and oral disorders
are not life
threatening, they may have systemic effects and can greatly reduce a person's quality of
life. Poor oral hygiene and inadequate
dental check-ups are major risk factors for
developing dental and oral disorders.
According to JADA
dental caries is one of the most common childhood
I
diseases.
Prevalence increases with age.51.6% of the children had at least one carious lesion or
filling in the coronal portion of either a primary or a permanent tooth. These proportions
increased to 77.9% for 17 year-olds and 84.7% for adults 18 years and over.Also, most
adults, 25 years and over have periodontal disease with at least 2mm attachment loss or
more. The percentage of adults with 6mm or more loss of attachment at one or more sites
increases at older age groups, with 19% of 55--64 year olds and 23.4% of65-74 year olds
having this amount of loss or more. At all ages, men are more likely than women to have
at least one tooth site with a 6mm or more loss of attachment. In addition to age and sex,
the prevalence of periodontal
loss of attachment also varies by racial\ethical
groups.
concerning tooth loss and edentulisrn, Phipps & Stevens (1995) and Neissen and Weyant
(1989) observed that most teeth are lost because of periodontal
caries.Byage
disease or dental
17 years, more than 7.3% of US children have lost at least one permanent
tooth because of caries. By age 50 years, Americans have lost an average of 12.1 teeth,
including the third molars. Men and women are nearly equally likely to be edentulous.
JADA also states that every year, about 1.2 million people develop cancer in the US
(based on 2000 estimates).Sites in the oral cavity and pharynx account for about 30,200
cases(2.4% of all cancers),and about 7,800 Americans die from these cancers each year.
The median age at diagnosis of oral and pharyngeal cancer is 64 years, and the rate of
occurrence increases with age. More than 95% of oral cancers occur in individuals aged
35 years and older. Overall 5-year survival rate for people with oral cavity and
pharyngeal cancer is 52%. The incidence for oral and pharyngeal cancer is decreasing
with an estimated annual percentage
decrease of 0.5% per year between
1975 and
1996.Tobbaco use bas been estimated has been estimated to account for over 90% of
4
cancers of oral cavity and pharynx., and thus presents the greatest single preventable risk
factor for oral cancer.
Other oral diseases
include oral herpes simplex infection
(prevalence is between 15-40%), recurrent apthous ulcers (prevalence between 5-25%),
and other mucosal conditions
like denture stomatitis (25.6% of 18 years and older
patients who have 2 fun dentures, 32.2% of those with one full denture, 26.7% of those
with one or more partial dentures and 0.87% of those without full or partial denture) and
candidiasis.
In a study by Astron & Kada to determine the perceived dental treatment needs among
older Tanzanian adults
2,
it was found that despite a moderate level of oral diseases, the
prevalence of perceived need for problem oriented care, dental check-ups and any type of
care was substantial
among older Tanzanians.
More over, socio-dernographics
reported oral health outcome variables alongside
correlates of need perceptions
clinical indicators
and
were important
across the outcome measures employed
in the study.
Brindle R, Wilson D,Harrison A,Connoly C and Cleaton Jones ,in a study to investigate
rates of dental caries and periodontal diseases, available dental service and resources and
perceived needs in a rural South African community 3,observed that caries prevalence in
age groups 35-54 was 69%,and 80% in 55 years and over. Caries was untreated and
where present, treatment had been extraction.Periodonbtal
disease prevalence was high,
but would respond to improved oral hygiene.
The aim of this study therefore,
is to determine the dental treatment needs of adult
patients visiting The University of Nairobi Dental Hospital.

LITERATURE
REVIEW.
A study of dental treatment needs of adults in Hiroshima prefecture (by Moshita
Masayuki and miyagu Msaharu of Hiroshima University)
4
found that total amount of
needs for operative dentistry services was4.7 million teeth. The number of adults who
required periodontal treatment was estimated to be about 1.8 rnilllion.The number of
people needing prosthodontic treatment was estimated to be about 0.4 million.
In a study done in US between 1988-94,about use of

needs among
modified CPITN
approach to
adults aged 20-79 years by socio
demographic characteristics 5,it was found that at least 3% of adult US population
required complex periodontal treatment or oral hygiene instructions. In another study to
assess the periodontal disease using CPITN in a rural population in Nineveh, Iraq
6,
it
was observed that only 12.5% of the sample had healthy gums and teeth, and calculus
was the most frequently observed periodontal condition. Another study done to show
periodontal treatment needs in Philippine adults
7
using CPITN showed that calculus
predominated as the most frequently recorded score, with a prevalence exceeding 70% in
young adults, but decreasing to about 40% in older adults. Decrease in prevalence of
calculus with age was associated with an increase in 4-5mm pocketing, 4% in young
adults and about 60% in older adults.Peridontally healthy mouths and cases of deep
pocketing were relatively uncommon. Assessed treatment needs were predominantly
scaling and improved oral hygiene. Need for complex treatment was low, involvimg only
4% of older adults. The pattern of assessed periodontal treatment needs of adults in the
Philippines was indicative of endemic gingivitis & calculus and moderate to low
prevalence of pocketing. In Saudi Arabia, a study to determine periodontal treatment
needs of adults 8found that the level of need for periodontal care in the sample chosen is
low when comparing to other countries. In Finland, a study to determine periodontal
treatment needs of the population aged 30 years and over
9,
observed that 3.4% had
healthy periodontal status, while plaque retention was found in 96.6% of the subjects.

In a study to determine the prosthodontic treatment needs of Canadian adults aged 85
years and over
10,
it was observed that only 31% of dentate nursing home residents and
47% of dentate independently
living subjects had received dental care in the year
previous to examination. The overall prevalence of edentulism was 66% and about 80010
of subjects wore at least one denture. Of the dentate subjects, over 60% had untreated
decay and 47% of nursing home residents had untreated root decay. Among nursing
home residents,
about 45% of dentate subjects required tooth extractions

and 56%
treatment. Although only 27% of dentate independently
residents required tooth extractions,
over 60% needed restorative

Bernabe & Flores did a study to determine orthodontic treatment need in Peruvian young
adults
They observed that about a third of the sample presented severe or very severe

malocclusion.
No significant
difference
was found in treatment
needs between the
different sexes. In this population, malocclusion was characterized by a relatively high
frequency of missing teeth, appreciable dental crowding and inadequate antero-posterior
relationships. In a study entitled orthodontic treatment needs in Asian adult males
13,
it
was observed that 50% of the sample had a definite need for orthodontic treatment (DHC
grades 4&5), whereas 29.2% had a moderate need for treatment (DHC grade 3).The
occlusal trait most commonly observed was dental cross bite.
In a study by Hawkins, RA & Locker to determine the need for tooth extractions

it
was observed that 38% of nursing home residents and 21% of independently living

to investigate distribution and type of restorative treatment 15'itwas observed that 85% of
the patients had received a restoration or extraction,37% of these for caries and 63% for
other reasons. The proportion of adults who received treatment by age group differed
significantly, with those aged 25-34 years being least likely and those aged 35-44 years
being most likely. In a document entitled endodontic treatment and periapical health in
patients in the institute of dentistry in Odz 15,it was observed that the mean number of
endodontically
treated teeth increased with age ranging from 1.4-3.4 from ages 20-70
years and older.

RESEARCH PROBLEM:
.PROBLEM STATElViENT
Dental treatment need has been reported to be high in the world and it affects people of
different races, gender and socio-economic
status. However, people tend to seek dental
treatment only when they have signs and symptoms e.g. pain. After these are addressed,
patients do not come for follow up, thus the need for treatment still remains high even
among dental patients in the population.
STUDY JUSTIFICATION
There is inadequate information pertaining to dental treatment needs of adult patients in
Kenya The findings of this study will form a benchmark and could be used to plan for
the various patient needs for the patients visiting the school.
Main objective:
To determine the dental treatment needs among adults.
Specific objectives:
To determine the periodontal treatment needs.
To determine the conservative treatment needs.
To determine the surgical treatment needs.
To determine the prosthetic treatment needs
To determine orthodontic treatment needs
Hypothesis
Conservative treatment need is the most frequent treatment need among patients visiting
the university of Nairobi dental hospital.
