The purpose of this cross-sectional study was to identify risk markers and risk indicators for periodontal attachment loss in a remote Canadian community. Of special interest was the association between smoking and periodontal disease experience.
Data were collected from a convenience sample of 187 adult patients attending a dental office in a rural community located in Northern Ontario. Information was obtained via a questionnaire and a periodontal examination. The questionnaire included the use of dental services, self-care behaviors, general health status, smoking, and personal characteristics. Periodontal health was assessed using the mean periodontal attachment loss (MPAL), measured at two sites on all remaining teeth and the proportions of sites examined with loss of 2 mm or more and 5 mm or more. Plaque scores and measures of the number of missing teeth also were obtained. The relationships between mean periodontal attachment loss, the proportion of sites with 5 mm or more of loss and independent variables such as age, sex, current smoking status, mean tooth plaque scores, flossing frequency, and regularity of preventive dental visits were examined in bivariate and multivariate analyses.
The data revealed a mean periodontal attachment loss of 3.9 mm (SD=1.5). The mean proportion of sites examined with loss of 2 mm or more was 0.89 and the mean proportion with loss of 5 mm or more was 0.35. In linear regression analysis, plaque scores, the number of missing teeth, age, current smoking status, regularity of dental visits, and flossing frequency had statistically significant independent effects and explained 60.0 percent of the variance in mean periodontal attachment loss. Just over 30 percent of subjects had severe periodontal disease, defined as 50 percent or more of sites examined with loss of 5 mm or more. In logistic regression analysis, missing teeth, dental visiting, smoking status, age, and flossing frequency had significant independent effects. The strongest association observed was with smoking, which had an odds ratio of 6.3. The logistic regression model correctly predicted 64.3 percent of cases with severe disease.
The data indicate that the periodontal health of these patients is poor. Risk indicators or markers of poor periodontal health in the population studied included missing teeth, plaque scores, age, current smoking status, regularity of dental visits, and flossing frequency. This supports previous findings that behavioral factors play an important role in periodontal disease.
本横断面研究旨在确定加拿大一个偏远社区牙周附着丧失的风险标志物和风险指标。特别感兴趣的是吸烟与牙周疾病经历之间的关联。
数据收集自安大略省北部一个农村社区牙科诊所的187名成年患者的便利样本。通过问卷调查和牙周检查获取信息。问卷包括牙科服务的使用、自我护理行为、总体健康状况、吸烟情况和个人特征。使用平均牙周附着丧失（MPAL）评估牙周健康状况，在所有剩余牙齿的两个部位进行测量，并计算检查部位丧失2毫米或更多以及5毫米或更多的比例。还获取了菌斑评分和缺失牙数量的测量值。在双变量和多变量分析中，研究了平均牙周附着丧失、丧失5毫米或更多部位的比例与年龄、性别、当前吸烟状况、平均牙菌斑评分、使用牙线频率以及定期进行预防性牙科就诊等自变量之间的关系。
数据显示平均牙周附着丧失为3.9毫米（标准差=1.5）。检查部位丧失2毫米或更多的平均比例为0.89，丧失5毫米或更多的平均比例为0.35。在线性回归分析中，菌斑评分、缺失牙数量、年龄、当前吸烟状况、牙科就诊的规律性以及使用牙线频率具有统计学上显著的独立影响，并解释了平均牙周附着丧失变异的60.0%。略超过30%的受试者患有严重牙周疾病，定义为检查部位50%或更多丧失5毫米或更多。在逻辑回归分析中，缺失牙、牙科就诊、吸烟状况、年龄和使用牙线频率具有显著的独立影响。观察到的最强关联是与吸烟，其比值比为6.3。逻辑回归模型正确预测了64.3%的严重疾病病例。
数据表明这些患者的牙周健康状况较差。在所研究人群中，牙周健康不佳的风险指标或标志物包括缺失牙、菌斑评分、年龄、当前吸烟状况、牙科就诊的规律性以及使用牙线频率。这支持了先前的研究结果，即行为因素在牙周疾病中起重要作用。
