The relative importance of risk factors of periodontitis varies from one population to another. In this study, we sought to identify independent risk factors of periodontitis in a Yemeni population.
One hundred and fifty periodontitis cases and 150 healthy controls, all Yemeni adults 30-60 years old, were recruited. Sociodemographic data and history of oral hygiene practices and oral habits were obtained. Plaque index (PI) was measured on index teeth. Periodontal health status was assessed using Community Periodontal Index (CPI) and Clinical Attachment Loss (CAL) according to WHO. Periodontitis was defined as having one or more sextants with a CPI score ≥ 3. Multiple logistic regression modelling was employed to identify distal, intermediate and proximal determinants of periodontitis, while ordinal regression was used to identify those of CAL scores.
In logistic regression, PI score was associated with the highest odds of periodontitis (OR = 82.9) followed by cigarette smoking (OR = 12.8), water pipe smoking (OR = 10.2), male gender (OR = 3.4) and age (OR = 1.19); on the other hand, regular visits to the dentist (OR = 0.05), higher level of education (OR = 0.37) and daily dental flossing (OR = 0.95) were associated with lower odds. Somewhat similar associations were seen for CAL scores (ordinal regression); however, qat chewing was identified as an additional determinant (OR = 4.69).
Water pipe smoking is identified as a risk factor of periodontitis in this cohort in addition to globally known risk factors. Adjusted effect of qat chewing is limited to CAL scores, suggestive of association with recession.
牙周炎危险因素的相对重要性因人群而异。在本研究中，我们试图确定也门人群中牙周炎的独立危险因素。
招募了150例牙周炎患者和150名健康对照者，均为30至60岁的也门成年人。收集了社会人口学数据、口腔卫生习惯和口腔习惯史。在指数牙上测量菌斑指数（PI）。根据世界卫生组织的标准，使用社区牙周指数（CPI）和临床附着丧失（CAL）评估牙周健康状况。牙周炎定义为一个或多个牙区段的CPI评分≥3。采用多元逻辑回归模型确定牙周炎的远端、中间和近端决定因素，而有序回归用于确定CAL评分的决定因素。
在逻辑回归中，PI评分与牙周炎的最高比值比相关（OR = 82.9），其次是吸烟（OR = 12.8）、抽水烟（OR = 10.2）、男性性别（OR = 3.4）和年龄（OR = 1.19）；另一方面，定期看牙医（OR = 0.05）、较高的教育水平（OR = 0.37）和每天使用牙线（OR = 0.95）与较低的比值比相关。CAL评分（有序回归）也有类似的关联；然而，嚼恰特草被确定为另一个决定因素（OR = 4.69）。
除了全球已知的危险因素外，抽水烟在该队列中被确定为牙周炎的危险因素。嚼恰特草的校正效应仅限于CAL评分，提示与牙龈退缩有关。
