Primary double tooth with partial anodontia of permanent dentition: a case report
Dental anomalies of number and forms may occur in the primary and permanent dentition. Various terms have
been used to describe dental twinning anomalies: gemination, fusion, concrescence, double teeth, cojoined teeth,
twinned teeth, geminifusion and vicinifusion. Double tooth is a term used to describe connate tooth and includes
both dental fusion and gemination. The phenomenon of gemination occurs when two teeth develop from one single
bud leading to a larger tooth. Fusion is a condition in which the crowns of two separate teeth have been joined toge-
ther during the crown development. Fusion occurs infrequently but could cause esthetic, spacing and periodontal
problems. The present article highlights the presence of a primary double tooth in an 11 year old boy involving
primary mandibular left lateral incisor and canine. Clinical examination and radiographic examination confirmed
the absence of the permanent left mandibular lateral incisor. Cases with primary double tooth necessitate careful
examination as they may be associated with anomalies in the succeeding permanent dentition and require proper
treatment plannin
