| Introduction | |  |
Odontoclastoma is a dental anomaly of deciduous tooth reported number of times in world literature till date.[1],[2],[3],[4]
Odontoclastoma presents as a tooth with pink coloured clinical crown. Radiographic evaluation reveal internal resorption of tooth and invasion of pulp by granulation tissue.
The odontoclastoma is an unusual form of tooth resorption which begins centrally within the tooth. The first evidence of the lesion is usually the appearance of a pink wide area on the crown of the tooth wherein the resorbed area is replaced by hyperplastic vascular tissue. The etiological factor responsible is increased localised internal pressure of granulation tissue arising in the periodontium.
Sahara et al[5] confirmed that the odontoclastic activity was initially detected only on the pulpal surface at the bottom area of the crown. It gradually spread towards pulpal horn region along with pulp chamber. The internal resorption of coronal dentin did not continue until the teeth exfoliated. After the termination of resorption the resorbed dentin surface was repaired by cementum like depositions covered with fibrous connective tissue.

A nine year old male patient reported to the department of Pedodontics, U.P. King George's University of Dental Sciences, Lucknow, with palatal eruption of 11, which was irritating the tongue [Figure - 1]. The clinical picture revealed that 53 had internal resorption exhibiting pinkish appearance [Figure - 2]. The patient maintained good oral hygiene and 54 and 55 were carious proximally.
On radiographic examination, the intra oral periapical radiograph revealed an ovoid radiolucent area in the central portion of tooth associated with pulp but not with external surface of tooth [Figure - 3]. The radiograph showed the palatoversion of 11 and superimposition of 12 and 13 erupting prematurely due to early resorption of 53. The internal resorption in 53 facilitated the premature eruption of 12 and 13 creating deleterious effect on the adjacent teeth and surrounding soft and hard tissue.
| Discussion | | |
Under local anaesthesia, the crown was extracted. The crown consisted of very thin enamel with ovoid depression in centre revealing the odontoclastoma of the crown structure. The cause of odontoclastoma is unknown but it may be due to an impact on the structure and damage to blood supply of the pulp. Odontoclastoma is usually symptomless until the pulp is exposed and allows access to infection. Usually the resorption may be detected by chance in routine radiographs.
The development of this structure is quite controversial. More insight on the development shall be achieved after the histopathological analysis which will be subsequent to section cutting. The treatment modalities consist of root canal treatment if the condition is discovered before perforation of crown or root.[5] In extensive cases of resorption, removal of complete structure is the treatment of choice.
