Objectives: The objective of this study was to find the prevalence of agenesis of third molar among the younger population of India. Materials and Methods: A cross-sectional study was conducted, and a younger population (13–21 years) born in the twenty-first century were included. Individuals who required an orthopantomogram, for any reason, were recruited in the study. Results: A total number of 850 orthopantomograms were studied, and 298 (35.05%) individuals showed the agenesis of at least 1 or more third molars. The most common pattern of agenesis was the missing of both maxillary third molars, followed by the agenesis of all third molars. The frequency of agenesis was 18 >28 >48 >38. The study showed a significant predilection in the maxilla as compared to the mandible. There was no statistically significant gender predilection for agenesis of third molar. Conclusion: The prevalence of third molar agenesis is increasing rapidly with time, with no significant gender predilection and changing trends of patterns of agenesis.
