The aim of this study was to evaluate severe tooth loss and associated factors among the elderly. A homebased crosssectional study, using random probabilistic sampling, was conducted with elderly persons from Cruz Alta, Rio Grande do Sul, Brazil. Oral health was examined and a structured questionnaire was answered. Associations between severe tooth loss and independent variables were determined using Poisson regression with robust variance. The level of significance adopted was 5%. Overall, 287 elderly persons were included. Among the elderly, 86 (29.9%) were edentulous, and 282 (98.3%) had lost at least one tooth. In this sample, median tooth loss was 21 (mean±standard deviation: 19.69±8.21). The sample was dichotomized into two groups according to the definition of severe tooth loss: less than nine remaining teeth or ≥9 remaining teeth. The prevalence of severe tooth loss was 60.3% (n=173). Females were associated with higher prevalence ratio (PR) of severe tooth loss (PR; 95% CI: 1.77; 1.39 - 2.24). Higher level of education was associated with lower PR of severe tooth loss (PR; 95% CI: 0.48; 0.30 - 0.77). The lack of access to dental care was associated with severe tooth loss (PR; 95% CI: 1.38; 1.13 - 1.67). Conversely, frequency of toothbrushing was not significantly associated with severe tooth loss (PR; 95% CI: 0.88; 0.73 - 1.06). High prevalence of severe tooth loss among the elderly was observed and found to be associated with sex, level of education, and access to dental care.
本研究的目的是评估老年人中严重牙齿缺失情况及相关因素。采用随机概率抽样方法，对来自巴西南里奥格兰德州克鲁斯阿尔塔的老年人进行了一项基于家庭的横断面研究。对口腔健康进行了检查，并让他们回答一份结构化问卷。使用具有稳健方差的泊松回归确定严重牙齿缺失与自变量之间的关联。采用的显著性水平为5%。总体而言，纳入了287名老年人。在这些老年人中，86人（29.9%）无牙，282人（98.3%）至少掉了一颗牙。在这个样本中，牙齿缺失的中位数为21颗（均值±标准差：19.69±8.21）。根据严重牙齿缺失的定义，将样本分为两组：剩余牙齿少于9颗或≥9颗。严重牙齿缺失的患病率为60.3%（n = 173）。女性严重牙齿缺失的患病率比值（PR）较高（PR；95%置信区间：1.77；1.39 - 2.24）。较高的教育水平与严重牙齿缺失的较低PR相关（PR；95%置信区间：0.48；0.30 - 0.77）。无法获得牙科护理与严重牙齿缺失相关（PR；95%置信区间：1.38；1.13 - 1.67）。相反，刷牙频率与严重牙齿缺失无显著关联（PR；95%置信区间：0.88；0.73 - 1.06）。观察到老年人中严重牙齿缺失的患病率较高，且发现其与性别、教育水平和获得牙科护理的情况有关。
