Population-based studies assessing self-reported periodontal questions in low-income countries are lacking, and therefore we aimed to assess the accuracy of self-reported periodontal items in Brazil. One thousand one hundred and forty adults from Florianópolis, Brazil, had their periodontium clinically examined, and responded to the following self-reported items on periodontal conditions: Question (Q)1, Do you have any wobbly teeth?; Q2, Do your gums usually bleed?; and Q3, Has your dentist ever told you that you have gum disease? Periodontitis was defined as: a. ≥ 6.0 mm periodontal pocket and ≥ 4.0 mm clinical attachment loss in the same tooth, in at least one tooth (PD1); or b. ≥ 6.0 mm periodontal pocket and ≥ 4.0 mm clinical attachment loss, not necessarily in the same tooth (PD2). Sensitivity (SN) and specificity (SP) were calculated, and analyses were stratified by socioeconomic status and time since last dental visit. Scores were generated in order to determine the accuracy of the whole set of items. Receiver operating characteristic (ROC) curves were plotted. Prevalence of clinically diagnosed periodontitis was 2.6% (95%CI = 1.7-4.0%) for PD1 and 3.8% (95%CI = 2.7-5.3%) for PD2. Prevalence of self-reported periodontitis varied between 2.7 (Q2) and 22.0% (Q3). SN and SP ranged between 0.0-60.0% and 73.3-98.6%, respectively; Q1 showed the highest accuracy (140.8%) followed by Q3 (140.0%). The combined score of the three self-reported items did not improve accuracy estimates; the areas under the ROC curves were 0.70 and 0.68 for PD1 and PD2, respectively. The accuracy of self-reported items was low, and further studies are needed in order to develop valid and reliable periodontitis screening questions for population-based studies.
在低收入国家，缺乏基于人群的研究来评估自我报告的牙周问题，因此我们旨在评估巴西自我报告的牙周项目的准确性。来自巴西弗洛里亚诺波利斯的1140名成年人接受了牙周临床检查，并对以下关于牙周状况的自我报告项目做出了回应：问题（Q）1，你有牙齿松动吗？；Q2，你的牙龈通常会出血吗？；以及Q3，你的牙医是否曾告诉你患有牙龈疾病？牙周炎的定义为：a. 至少一颗牙齿的牙周袋深度≥6.0毫米且临床附着丧失≥4.0毫米（PD1）；或b. 牙周袋深度≥6.0毫米且临床附着丧失≥4.0毫米，不一定在同一颗牙齿上（PD2）。计算了敏感性（SN）和特异性（SP），并按社会经济地位和上次牙科就诊后的时间进行分层分析。生成分数以确定整套项目的准确性。绘制了受试者工作特征（ROC）曲线。PD1临床诊断牙周炎的患病率为2.6%（95%置信区间=1.7-4.0%），PD2为3.8%（95%置信区间=2.7-5.3%）。自我报告的牙周炎患病率在2.7%（Q2）至22.0%（Q3）之间。SN和SP分别在0.0-60.0%和73.3-98.6%之间；Q1显示出最高的准确性（140.8%），其次是Q3（140.0%）。三个自我报告项目的综合得分并未提高准确性估计；PD1和PD2的ROC曲线下面积分别为0.70和0.68。自我报告项目的准确性较低，需要进一步研究以开发适用于基于人群研究的有效且可靠的牙周炎筛查问题。
