Despite the interdependence of general and periodontal health, there is paucity of national representative data on the prevalence of periodontal diseases and their associated risk factors in Egyptian population. This cross-sectional study, thus, aimed to assess the prevalence of periodontitis and tooth loss among Egyptian adults and investigate the association between potential risk factors and periodontal diseases.
A total of 5,954 adults aged ≥ 20 years were included in this study as a subsample from Egypt's national oral health survey. Periodontitis was diagnosed with Community Periodontal Index 'CPI' scores ≥3 and tooth loss not due to caries was included in the analysis. Socio-demographic data and information on behavioral factors and history of diabetes were gathered in a face-to-face interview. Logistic regression was done to interpret the impact of potential predictors on the incidence of the two selected outcome variables.
The overall prevalence of periodontitis was 26% and regression analysis revealed that higher odds of periodontitis existed among illiterate participants (OR = 1.74; 95% CI: 1.40-2.17), smokers (OR = 1.93; 95% CI: 1.69-2.20) and rural residents (OR = 1.16; 95% CI: 1.03-1.30). On the other hand, old age, frequency of dental attendance and history of diabetes were the main predictive factors for tooth loss.
Among Egyptian adults, periodontal diseases were strongly associated with a multitude of modifiable and non-modifiable risk factors and inequalities in distribution of periodontal treatment needs were determined mainly by age, gender, level of education and residency location.
尽管一般健康和牙周健康相互依存，但埃及人群中牙周病及其相关危险因素的流行情况缺乏全国代表性数据。因此，本横断面研究旨在评估埃及成年人牙周炎和牙齿缺失的患病率，并调查潜在危险因素与牙周病之间的关系。
本研究共纳入 5954 名年龄≥20 岁的成年人作为埃及国家口腔健康调查的亚样本。使用社区牙周指数（CPI）评分≥3 诊断牙周炎，将非龋齿导致的牙齿缺失纳入分析。通过面对面访谈收集社会人口统计学数据以及行为因素和糖尿病史信息。采用逻辑回归解释潜在预测因素对两个选定结局变量发生率的影响。
牙周炎的总体患病率为 26%，回归分析显示，文盲参与者（OR=1.74；95%CI：1.40-2.17）、吸烟者（OR=1.93；95%CI：1.69-2.20）和农村居民（OR=1.16；95%CI：1.03-1.30）发生牙周炎的可能性更高。另一方面，年龄较大、就诊频率和糖尿病史是牙齿缺失的主要预测因素。
在埃及成年人中，牙周病与多种可改变和不可改变的危险因素密切相关，牙周治疗需求的分布不均主要取决于年龄、性别、教育水平和居住地点。
