Abstract

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.

二十一世纪出生的印度年轻人中第三磨牙发育不全的情况。
研究目的本研究旨在了解印度年轻人群中第三磨牙缺失的发病率:研究对象为 21 世纪出生的年轻人(13-21 岁)。研究招募了因任何原因需要进行口腔正畸检查的人:结果:共研究了 850 张正畸照片,其中 298 人(35.05%)至少有一颗或多颗第三磨牙发育不全。最常见的第三磨牙缺失模式是两颗上颌第三磨牙缺失,其次是所有第三磨牙缺失。缺失的频率为 18 颗 >28 颗 >48 颗 >38 颗。研究显示,与下颌骨相比,上颌骨的缺失率更高。结论:第三磨牙缺失的发病率与性别有关:结论:随着时间的推移,第三磨牙缺失的发病率正在迅速上升,没有明显的性别偏好和缺失模式的变化趋势。
