Abstract : This paper report a case describing the diagnosis and treatment of an external root resorption in the upper right central
incisor with surgical approach following endodontic treatment using the new dental cement Biodentine™ in an attempt to repair the
defect. Early diagnosis and appropriate treatment are the keys to a successful outcome. This case report presents a favorable clinical
outcome when Biodentine was used for treating external cervical resorption.

INTRODUCTION
External root resorption is a progressive and
destructive loss of tooth structure, initiated by a
mineralized or denuded area of the root surface.
Invasive cervical resorption is a clinical term used to
describe a relatively uncommon, insidious, and often
aggressive form of external root resorption.(1) It is
seen in most cases as a late complication of
traumatic injuries of the teeth, but it may also occur
after

leading to improper treatment or unnecessary loss of
the tooth (4) Materials such as amalgam, composite
resin, glass ionomer, and mineral trioxide aggregate
(MTA) have been used in past for restoring the
resorptive defect (Isidoret al., 2006). The present
case involved the use of new calcium silicate-based
cement called Biodentine (Septodont, Saint-Maurdes-Fosses, France) for the treatment of an invasive
cervical resorption in the maxillary right central
incisor.

External cervical resorption(ECR) is the loss of
dental hard tissue as a result of odontoclastic action.
This inflammatory tissue loss occurs immediately
below the epithelial attachment of the tooth(5).The
exact cause of External cervical resorption is poorly

the root surface and therefore initiate external

etiology (6, 7).Heithersay (1999) classified ECR
according to the extent of the lesion within the tooth:
class 1; a small invasive resorptive lesion near the
cervical area with shallow penetration into dentin;
class 2; a well-defined invasive resorptive lesion that
has penetrated close to the coronal pulp chamber but
shows little or no extension into radicular dentin,
class 3; a deeper invasion of dentin by resorbing
tissue, not only involving the coronal dentin but also
extending at least to the coronal third of the root and
class 4; a large invasive resorptive process that has
extended beyond the coronal third of the root canal
(8) . A pink spot in the cervical region of the tooth is
usually the clinical sign noticed by the patient and/or
dentist that brings the problem to light. If there is no
pink spot indicating ECR, then the condition might
go unnoticed until there is pulpal and/or periodontal
involvement, because these lesions are usually
painless.External cervical resorption defects are
