A retrospective study of double teeth in the primary dentition.
The study was carried out on 20 subjects with evidence of double teeth, which included gemination and fusion, in the primary dentition. The age of the subjects ranged from 2 1/2 to 9 years. The results of the study indicated that double teeth occurred more frequently in the males and that fusion was much more prevalent than gemination. The frequency of occurrence in the right and left side of the jaws was comparable. About 79 percent of the occurrence was seen in the mandibular arch. A high proportion of fusion was found to involve the lateral incisors and canines. In 50 percent of the occurrence, hypodontia of the permanent dentition was observed, all of which involved the lateral incisors. The clinical significance of the condition was also discussed.[1]References
