A cross-sectional study was designed to assess the prevalence of periodontal diseases among tobacco and non-tobacco users. A total of 2,156 dentate subjects were selected in the age group of 35-44 years through multi-stage sampling method. A total of 350 and 175 subjects were selected from household survey from each district in rural and urban areas. Subjects were interviewed for the tobacco usage status, followed by clinical assessment of periodontal status. Prevalence of calculus, periodontal pockets of 4-5 mm depth and loss of attachment of 0-3 mm and 4-5 mm was significantly more frequent among current tobacco users. The subject with smoking and chewing tobacco has an odds ratio (OR) 1.6 (95% confidence intervals [CI] 1.14-2.31) and OR 1.7 (95% CI 1.38-2.28) respectively. The findings contribute to the evidence of smoking as a risk factor for periodontal disease.
一项横断面研究旨在评估吸烟和非吸烟人群牙周病的患病率。通过多阶段抽样方法，在 35-44 岁年龄组中选择了 2156 名有牙的受试者。分别从农村和城市地区的每个区的家庭调查中选择了 350 名和 175 名受试者。对受试者进行了烟草使用情况的访谈，然后对牙周状况进行了临床评估。在目前吸烟的人群中，牙石、4-5 毫米深牙周袋和 0-3 毫米和 4-5 毫米附着丧失的患病率明显更高。吸烟和咀嚼烟草的受试者的优势比（OR）分别为 1.6（95%置信区间[CI] 1.14-2.31）和 1.7（95%CI 1.38-2.28）。这些发现为吸烟是牙周病的危险因素提供了证据。
