Abstract

Background: One of the most prevalent dental abnormalities, third molar agenesis, or the congenital lack of wisdom teeth, may be a reflection of current evolutionary patterns. There is still little information on its prevalence in Central India, despite the fact that there have been several research conducted elsewhere.

Materials and Methods: A retrospective analysis of 1962 OPGs (1004 females, 958 males) from 2019 to 2023 was conducted. The presence or absence of third molars was assessed in OPGs. Data were analysed to assess overall prevalence, gender distribution, jaw involvement, and yearly trends.

Results: Third molar agenesis was observed in 29.45% of the study population, with a higher prevalence in females (30.78%) than males (28.07%). The prevalence showed a consistent increase from 2019 (27.35%) to 2023 (33.52%). The maxilla had a greater frequency of bilateral agenesis than the mandible, and bilateral agenesis was more frequent than unilateral. The most frequent pattern observed was agenesis of all four third molars.

Conclusion: The study indicates a rising trend in third molar agenesis over time, especially among females and in the maxillary arch. The findings suggest that third molars are progressively becoming vestigial, likely influenced by evolutionary, genetic, and environmental factors. Continuous surveillance of third molar development can aid in understanding craniofacial growth patterns and guiding dental treatment planning.
