Abstract

Objective: This study aims to examine the dental anomalies (tooth number, size, and structural anomalies) in a group of pediatric dental population and the difference between the genders in terms of the prevalence of these anomalies.

Methods: In this retrospective study, digital orthopantomograms belonging to 5000 patients aged 5-14 years, taken at the Faculty of Dentistry of Erciyes University were evaluated. Tooth number anomalies (hypodontia, hyperdontia, anodontia, and mesiodens) and dental pathology (odontoma and cyst-tumor) were evaluated in orthopantomograms. The frequencies of dental anomalies were compared, and their distribution by gender was examined using descriptive tests and chi-square tests.

Result: Of 5000 patients, 169 (3.38%) had 1 dental anomaly. Of the patients, 137 (81%) had hypodontia, 27 (15.9%) hyperdontia, 6 (3.5%) mesiodens, 2 (1.1%) odontoma, and (1.7%) cysts-tumor-like structures. The prevalence of hypodontia was found to be higher in girls than in boys (P < .05). There was a difference between the genders in terms of the prevalence of hypodontia (P < .05). No difference was found between the genders in terms of other dental anomalies (P > .05).

Conclusion: Whether common or rare, dentists should be careful about the presence of dental anomalies while examining their patients. Detecting these anomalies and performing interventions in the required period is important to prevent complications that may occur in the future. In this way, psychological, aesthetic, phonational, and physical problems that may occur in the future lives of children and adolescents can be prevented.
