Hypodontia, Hyperdontia and Concomitant Hypohyperdontia Prevalence in the Western Turkish Population

Objectives To describe the dental and sex-related distributions and the prevalence of numerical dental anomalies in the Western Turkish population and compare the results with those in the literature. Materials and Methods A comprehensive investigation was conducted on panoramic X-rays from a total of 10,000 individuals, with 5,088 identified as female and 4,912 as male. The analysis focused on the identification of numerical dental anomalies. To evaluate potential sex-related differences, the Mann‒Whitney U test was performed. Results The prevalence of hypodontia was 3.72%, that of hyperdontia was 0.77%, and that of concomitant hypohyperdontia was 0.04%. The prevalence of hyperdontia and hyperdontic anterior teeth was found to be higher in females than in males. However, no significant differences in the prevalence of hypodontia were observed between the sexes. Conclusion There is an evident necessity to modernize the available data concerning the prevalence of dental numerical anomalies, particularly those classified as hypohyperdontia. The present study has made a significant contribution to the existing body of knowledge in this area. A tendency towards hyperdontia has been observed in males. However, no significant differences in hypodontia or concomitant hypohyperdontia have been identified among the Western Turkish population based on sex. Prevalence values are contingent upon the size and characteristics of the population.
