Concrescent triplets involving primary anterior teeth
A 7-year-old boy complained of palatally erupting upper front tooth and a retained primary tooth. An examination revealed palatal eruption of permanent maxillary left central incisor. Also, visible was an erupted supplemental tooth bearing resemblance to a miniature incisor. It was present between the deciduous maxillary left central and lateral incisors (61 and 62 respectively – Fédération Dentaire Internationale (FDI) notation). The teeth 61 and 62 were carious and lacked mobility. Also, the tooth 61 was black in color. History revealed trauma to the upper anterior region when the child was 1 year of age. He had fallen face forwards while waddling. Medical and family history was non-contributory.\nA radiograph revealed cariously infected 61 and 62 with a supplemental tooth in between []. It was decided to extract all the three teeth taking into consideration age of the child, presence of infected teeth and eruptive status of succedaneous teeth. Attempts at removal of a single tooth resulted in extraction of all the three teeth en bloc. Examination revealed that these teeth were joined together by the roots [Figures and ].\nThe specimen was thereafter, sent for histopathology. The teeth were decalcified in 3% nitric acid and the prepared sections (5 μm) stained with hematoxylin and eosin. The sections revealed the union of teeth by cementum [Figures and ].
