This investigation examined current practices of brushing, flossing, and periodic dental visits and their association with periodontal health status.
Data were collected using face-to-face interviews and 40-minute in-home dental examinations with a probability sample of adults 18 years of age or older, having at least one tooth, and living in housing units in the Detroit tricounty area. Complete examinations were performed on 319 individuals.
On average, subjects reported brushing their teeth about twice a day. About one-third of the population reported flossing at least once a day. Loss of periodontal attachment was related to frequency of brushing while subjects who exhibited acceptable flossing ability had less plaque and calculus, shallower pocket depths, and less attachment loss. Subjects reporting a periodic dental visit at least once a year had less plaque, gingivitis, and calculus than subjects reporting less frequent visits. In regression analyses, brushing thoroughness, flossing ability and frequency, and dental visit frequency were predictors of lower plaque, gingivitis, and calculus scores. In turn, these scores were predictors of shallower pocket depths and less attachment loss.
Brushing, flossing, and periodic dental visits were correlated with better periodontal health. The behaviors appeared to be indirectly related to pocket depth and attachment loss through their associations with plaque, gingivitis, and calculus levels.
本研究调查了刷牙、使用牙线以及定期看牙的当前情况及其与牙周健康状况的关联。
通过面对面访谈以及40分钟的上门牙齿检查收集数据，样本为底特律三县地区年龄在18岁及以上、至少有一颗牙齿且居住在住房单元中的成年人概率样本。对319名个体进行了全面检查。
平均而言，受试者报告每天刷牙约两次。约三分之一的人报告每天至少使用一次牙线。牙周附着丧失与刷牙频率有关，而牙线使用能力良好的受试者牙菌斑和牙结石较少、牙周袋深度较浅且附着丧失较少。报告每年至少定期看一次牙的受试者比看牙频率较低的受试者牙菌斑、牙龈炎和牙结石更少。在回归分析中，刷牙彻底程度、牙线使用能力和频率以及看牙频率是牙菌斑、牙龈炎和牙结石得分较低的预测因素。反过来，这些得分又是牙周袋深度较浅和附着丧失较少的预测因素。
刷牙、使用牙线和定期看牙与更好的牙周健康相关。这些行为似乎通过与牙菌斑、牙龈炎和牙结石水平的关联而与牙周袋深度和附着丧失间接相关。
