Abstract

PURPOSE

This study was conducted to document the prevalence of occlusal caries experience and periodontal pathology for erupting third molars in young adults.

PATIENTS AND METHODS

The data are from 49 subjects enrolled in an institutional review board-approved trial with at least one third molar below the occlusal plane at baseline that erupted by longest follow-up. Teeth were considered erupted if they reached the occlusal plane. Caries experience on the occlusal surface of third molars was assessed by a visual-tactile examination. At least 1 periodontal probing depth (PD) >or=4 mm in the third molar region was considered indicative of periodontal pathology. The third molar region was defined as the 6 probing sites around third molars and 2 sites on the distal of second molars. The prevalence of third molar caries experience and periodontal pathology at longest follow-up was assessed.

RESULTS

Most of the 49 subjects were female (51%), Caucasian (76%), and educated at least through high school (82%). Median age was 20.5 years (interquartile range [IQR] 18.4 to 24.1 years). Median follow-up was 5.1 years (IQR = 3.4 to 6.9 years). At baseline, none of the subjects had occlusal caries experience in a third molar; 51% of subjects had at least 1 PD >or=4 mm in a third molar region. At follow-up, 27% of the subjects had occlusal caries experience in at least 1 third molar that erupted to the occlusal plane; 61% had at least 1 PD >or=4 mm in a third molar region. Twenty-nine percent had occlusal caries in at least 1 third molar at the occlusal plane and at least 1 PD >or=4 mm in a third molar region. Thirty-seven percent had no third molar occlusal caries experience and all third molar region PD <4 mm.

CONCLUSIONS

For third molars that erupted "late," periodontal pathology was more prevalent than occlusal caries.

摘要

目的

本研究旨在记录年轻成年人中正在萌出的第三磨牙的咬合面龋经验和牙周病变的患病率。

患者与方法

数据来自49名受试者，这些受试者参加了一项经机构审查委员会批准的试验，基线时至少有一颗第三磨牙低于咬合平面，且在最长随访期时已萌出。牙齿到达咬合平面则视为已萌出。通过视诊-触诊检查评估第三磨牙咬合面的龋经验。第三磨牙区域至少有1个牙周探诊深度（PD）≥4 mm被认为提示有牙周病变。第三磨牙区域定义为第三磨牙周围的6个探诊位点和第二磨牙远中的2个位点。评估最长随访期时第三磨牙龋经验和牙周病变的患病率。

结果

49名受试者中大多数为女性（51%），白种人（76%），至少接受过高中教育（82%）。中位年龄为20.5岁（四分位间距[IQR]为18.4至24.1岁）。中位随访时间为5.1年（IQR = 3.4至6.9年）。基线时，没有受试者第三磨牙有咬合面龋经验；51%的受试者第三磨牙区域至少有1个PD≥4 mm。随访时，27%的受试者至少有1颗萌出至咬合平面的第三磨牙有咬合面龋经验；61%的受试者第三磨牙区域至少有1个PD≥4 mm。29%的受试者在咬合平面至少有1颗第三磨牙有咬合面龋且第三磨牙区域至少有1个PD≥4 mm。37%的受试者没有第三磨牙咬合面龋经验且所有第三磨牙区域PD＜4 mm。
