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.
目的
本研究的目的是找出印度年轻人群中第三磨牙先天性缺失的患病率。
材料与方法
进行了一项横断面研究，纳入了21世纪出生的年轻人群（13 - 21岁）。因任何原因需要拍摄口腔全景片的个体被纳入本研究。
结果
共研究了850张口腔全景片，298名（35.05%）个体显示至少有1颗或更多第三磨牙先天性缺失。最常见的先天性缺失模式是双侧上颌第三磨牙缺失，其次是所有第三磨牙先天性缺失。先天性缺失的频率为18 > 28 > 48 > 38。研究表明，与下颌相比，上颌有明显的先天性缺失倾向。第三磨牙先天性缺失在性别上无统计学显著差异。
结论
随着时间的推移，第三磨牙先天性缺失的患病率迅速上升，无明显性别倾向，且先天性缺失模式的趋势也在变化。
