The aim of this study was to identify the risk factors for tooth loss in an extended age group of adults over 4 years. The prospective cohort study assessed adults (20-64 years old) in 2011 and 2015, from Piracicaba, São Paulo, Brazil. The sample selection was planned based on the adult population in the city. The inclusion criteria were randomly selected residences per census tract unit (one adult per household). The exclusion criteria comprised of a physical or psychological state that prevented the achievement of clinical procedures or understanding of the questionnaire. The home oral examination was performed using the index of decayed, missing, and filled teeth (DMFT), the Community Periodontal Index according to the World Health Organization, and visible biofilm. Demographic and socio-economic data, information on health habits, and the use of dental services were obtained by questionnaire. The outcome was a presence incidence of tooth loss, assessed by the difference between Missing teeth (M>0) from DMFT in 2011 and that in 2015. The conceptual theoretical model 'Ethnicity, aging and oral health outcomes' was adapted for tooth loss and used in a Hierarchical multivariate Poisson Regression analysis (p<0.20). The reference category for the Poisson regression were individuals who had no missing teeth (M) due to caries or periodontal disease (p<0.05). There were a total of 143 (follow-up rate = 57.7%) participants in the four-year study, and there was incidence of tooth loss in 51 (35.7%) adults over this period. The risk factors for tooth loss were reason for seeking dental services by pain (RR = 2.72; 95.0% CI: 1.04-7.37), previous tooth loss (RR = 3.01; 95.0% CI: 1.18-7.73) and decayed teeth (RR = 2.87; 95.0% CI: 1.22-6.73). The risk factors for tooth loss were: reason for seeking dental services by pain, previous tooth loss and dental caries.
本研究旨在确定 4 年以上成年人牙齿缺失的风险因素。这项前瞻性队列研究评估了 2011 年和 2015 年来自巴西皮拉西卡巴的成年人（20-64 岁）。样本选择是基于城市的成年人口计划的。纳入标准为每个普查区单位随机选择的住所（每户一名成年人）。排除标准包括身体或心理状态，这会妨碍临床程序的实施或问卷的理解。家庭口腔检查使用龋齿、缺失和填补的牙齿指数（DMFT）、根据世界卫生组织的社区牙周指数和可见生物膜进行。通过问卷获得人口统计学和社会经济数据、健康习惯信息和牙科服务使用情况。结果是牙齿缺失的存在发生率，通过 2011 年和 2015 年 DMFT 中缺失牙齿（M>0）之间的差异来评估。“种族、老龄化和口腔健康结果”概念理论模型被改编用于牙齿缺失，并用于分层多变量泊松回归分析（p<0.20）。泊松回归的参考类别是由于龋齿或牙周病而没有缺失牙齿（M）的个体（p<0.05）。在四年的研究中，共有 143 名（随访率=57.7%）参与者，在此期间有 51 名（35.7%）成年人发生牙齿缺失。牙齿缺失的危险因素是因疼痛而寻求牙科服务的原因（RR=2.72；95.0%CI：1.04-7.37）、以前的牙齿缺失（RR=3.01；95.0%CI：1.18-7.73）和龋齿（RR=2.87；95.0%CI：1.22-6.73）。牙齿缺失的危险因素为：因疼痛而寻求牙科服务的原因、以前的牙齿缺失和龋齿。
