Dental twinning in Primary Dentition: A Case report

Abstract

Odontogenic anomalies can occur as a result of conjoining or twinning defects. These include fusion, gemination and concrescence. The process of odontogenesis cannot be seen, therefore fusion and germination seems to be equivalent. This case report is of a boy aged-5-year who visited private dental clinic with a complaint of decayed upper front teeth. On clinical examination, the patient was diagnosed with ECC (Early childhood caries) and presence of fusion between primary upper left central incisor ( 61) and a supernumerary tooth. Radiographic analysis showed presence of a two roots with two root canals and external root resorption. The case was discussed and treatment planning was done to extract the tooth as a result of resorption in the apical region. The purpose of this report is to highlight the importance of diagnosing dental anomalies in the primary dentition, so as to organize a conservative individualized treatment plan to prevent complications during the child's formative years.
