Abstract

PURPOSE

To assess the prevalence of third molar caries experience in a middle-aged and older population and the relationship of these findings to caries experience in teeth more anterior in the mouth.

PATIENTS AND METHODS

Data from 6,550 Dental Atherosclerosis Risk in Communities study participants aged 52 to 74 years who underwent a clinical examination for coronal caries experience were available for these analyses. Subjects with visible third molars (N = 2,003) were divided based on third molar coronal caries experience on at least 1 third molar: no carious/decayed coronal surface (DS) or at least 1 coronal DS and no filled coronal surface (FS) or at least 1 coronal FS. Coronal DS and FS were also calculated for more anterior teeth. Covariates included ethnicity, gender, age, body mass index, education, income, smoking status, and diabetes diagnosis. Subject level outcomes for third molar and more anterior teeth were compared by descriptive statistics and chi(2) or t tests with statistical significance set at P less than .05. Multivariate modeling was performed to adjust outcome variables for covariates.

RESULTS

Third molar caries experience was detected in 77% of subjects and was significantly associated with caries experience in more anterior teeth and white race (P < .01). Caries experience was detected in only third molars in 1% of subjects, and 1% of subjects were caries free. Subjects with less education (20%) and lower income (19%) were significantly more likely to have DS detected compared with subjects with more education (6%) and higher income (5%) (P < .01). Conversely, subjects with more education (75%) and higher income (77%) were significantly more likely to have FS detected compared with subjects with less education (55%) and lower income (60%) (P < .01).

CONCLUSIONS

Third molar coronal caries experience was significantly associated with caries experience in teeth more anterior in the mouth in this middle-aged and older population.

摘要

目的

评估中老年人群中第三磨牙龋病经历的患病率，以及这些结果与口腔中更靠前牙齿龋病经历的关系。

患者与方法

本分析采用了社区牙科动脉粥样硬化风险研究中6550名年龄在52至74岁之间接受冠龋临床检查的参与者的数据。有可见第三磨牙的受试者（N = 2003）根据至少一颗第三磨牙的冠龋经历进行分组：无龋/龋坏冠面（DS）或至少一个冠面DS且无充填冠面（FS）或至少一个冠面FS。还计算了更靠前牙齿的冠面DS和FS。协变量包括种族、性别、年龄、体重指数、教育程度、收入、吸烟状况和糖尿病诊断。通过描述性统计和卡方检验或t检验比较第三磨牙和更靠前牙齿的个体水平结果，设定统计学显著性为P < 0.05。进行多变量建模以调整协变量的结果变量。

结果

77%的受试者检测到第三磨牙龋病经历，且与更靠前牙齿的龋病经历和白人种族显著相关（P < 0.01）。仅在第三磨牙检测到龋病经历的受试者占1%，1%的受试者无龋。与受教育程度较高（6%）和收入较高（5%）的受试者相比，受教育程度较低（20%）和收入较低（19%）的受试者检测到DS的可能性显著更高（P < 0.01）。相反，与受教育程度较低（55%）和收入较低（60%）的受试者相比，受教育程度较高（75%）和收入较高（77%）的受试者检测到FS的可能性显著更高（P < 0.01）。
