BACKGROUND The co-occurrence of caries and periodontitis and a possible association is still a matter of debate. Thus, the aim of the study was to determine the co-occurrence of caries and periodontitis in Chilean adults. METHODS Evaluation of periodontal and dental status in 994 adults (35-44 years old) based on the First Chilean National Examination Survey 2007-2008. The prevalence of caries was defined as the percentage of participants with one or more teeth with untreated caries by using the D component of the DMFT index (DT ≠ 0). The prevalence of periodontitis was determined using standard case definitions for population-based surveillance of periodontitis described by the CDC-AAP. RESULTS Individuals with caries had an approximately 40% higher prevalence of severe (29.3% vs 20.8%, p < 0.05) and a 13% higher prevalence of total periodontitis (89.3% vs 78.4%, p < 0.05) than those without caries. Ordinal logistic regression revealed a positive association between periodontitis and the number of teeth with caries (DT ≠ 0; 3 or 4 teeth with caries: OR 1.74; CI = 1.12-2.29 p < 0.05; 5 or more teeth with caries: OR 2.47; CI = 1.66-3.67 p < 0.01). CONCLUSION Dental caries is associated with the severity and prevalence of periodontitis in Chilean adults. Individuals with 3 or more teeth with untreated caries are more likely to suffer from periodontal disease.

在智利成年人中，龋齿与严重的牙周炎有关：一项横断面研究。

背景技术龋齿和牙周炎的同时发生以及可能的关联仍然是争论的问题。因此，该研究的目的是确定智利成年人中龋齿和牙周炎的同时发生。方法根据2007-2008年智利第一次国家考试调查，对994名成人（35-44岁）的牙周和牙齿状况进行评估。龋齿的患病率定义为使用DMFT指数的D分量（DT≠0）的参与者中一颗或多颗牙齿未经治疗的龋齿的百分比。使用CDC-AAP描述的基于人群的牙周炎监测的标准病例定义来确定牙周炎的患病率。结果患有龋齿的个体的重症患病率大约高40％（29.3％vs 20.8％，p <0。05）和没有龋齿的人相比，总牙周炎的患病率高13％（89.3％对78.4％，p <0.05）。顺序逻辑回归显示牙周炎与龋齿数之间呈正相关（DT≠0； 3或4颗龋齿：OR 1.74； CI = 1.12-2.29 p <0.05； 5颗或更多龋齿：OR 2.47； 5颗或更多龋齿：OR 2.47； CI = 1.66-3.67 p <0.01）。结论龋齿与智利成年人牙周炎的严重程度和患病率有关。牙齿未经治疗的3颗或更多牙齿的个体更容易患牙周疾病。5颗或以上带有龋齿的牙齿：或2.47；CI = 1.66-3.67 p <0.01）。结论龋齿与智利成年人牙周炎的严重程度和患病率有关。患有3颗或更多牙齿且未治疗龋齿的个体更容易患牙周疾病。5颗或以上带有龋齿的牙齿：或2.47；CI = 1.66-3.67 p <0.01）。结论龋齿与智利成年人牙周炎的严重程度和患病率有关。患有3颗或更多牙齿且未治疗龋齿的个体更容易患牙周疾病。
