This article covers a clinical and epidemiological study, conducted by us, of 106 patients with clinically and radiologically diagnosed Supernumerary Teeth (ST).
The objective of this study was to determine the frequency, morphology and location of hyperdontiaby sex and age among the patients studied.
Material and methods: This is a case-control, observational, retrospective study of 106 patients with hyperdontia.
Results and conclusions: The male to female ratio in the studied patients was 2.21:1, with mean age of 16.84±1.15 years. In the mixed and primary dentition, the proportion of mesiodens was highest, while in the permanent dentition, the proportion of distomolar was highest. We diagnosed 65.47% (110 ST) in the maxilla, 14.29% (24 ST) in the mandible, and 20.24% (34 ST) affecting both jaws. Mesiodens and lateral incisor were more common in the maxilla, and parapremolar was more common in the mandible.
