Fusion is rare in the primary dentition (range .14 percent to 3 percent). Patients with fused primary lateral incisors and canines have about a 75 percent chance of lacking the succedaneous lateral incisor. Patients with fused incisors have less than a 20 percent chance of having a missing permanent tooth.
A trace of cementum totally surrounded by dentine could not be found here; this histological evaluation gave no further information about the origin of this double tooth. The fact that the dental pulp was complex could not be observed radiographically.

A case of a child with a maxillary primary left lateral incisor fused to a supernumerary was presented. The teeth were separated and restored using stainless steel crowns with composite facings. The described treatment permitted a maximum level of esthetics, function, and cleansability of the primary dentition, without compromising the permanent dentition.
The discovery of a rare combination of fusion and gemination in one clinical crown, involving the same primary teeth in two patients, within a short period of time, is described.

Based on the frequency of occurrence of cleft lip and palate (CLP) in a family, a distinction has been made between familial and sporadic CLP. It was presumed that the genetic predisposition in familial CLP is high, while in sporadic CLP environmental factors play an important role. This study describes the possible relationship between the incidence of dental anomalies and the genetic predisposition of CLP in both the deciduous and permanent dentition. Dental anomalies were studied in 100 CLP patients and 38 control subjects. Neither the number of dental anomalies, nor the numbers of missing and supernumerary teeth differed significantly between familial and sporadic cases. A comparison between subjects with and without CLP showed a significant difference in the morphology of the dentition of the upper jaw. This difference was quantitative rather than qualitative. This study indicates a direct relationship between cleft formation and formation of the teeth, irrespective of the genetic predisposition and the severity of the cleft (i.e. uni- or bilateral).
