Abstract

This study aimed to evaluate the influence of the number of dentists in the neighborhood on the incidence of dental caries in the children permanent dentition. This cohort began in 2010 (T1) with a random sample of 639 children (1 to 5 years-old) followed for 7 years, in southern Brazil. The follow-up reassessment (T2) took place in 2017. Untreated dental caries was evaluated at T2 through the Decayed, Missing, and Filled surfaces index (DMF-S). The number of dentists in the neighborhood was obtained from the city's official database and used as a contextual variable. Socioeconomic, demographic, and oral health variables at the individual level were evaluated at T1. A multilevel Poisson regression was performed to evaluate the influence of the predictor variables in the incidence of untreated dental caries. From 639 children at T1, 449 were reassessed at T2 (a 70.3% retention rate). The mean of decayed surfaces at T2 was 0.92 (SE 0.01). The greater the number of dentists in the neighborhoods where the children lived, the lower the incidence of dental caries. Children with low socioeconomic status, who have not routinely visited the dentist in the last 6 months, who presented a experience of dental caries, and whose parents perceived their oral health as fair/poor showed a higher incidence of surfaces with untreated dental caries. As conclusion, children who live in neighborhoods with fewer dentists have a higher incidence of untreated dental caries in permanent dentition.

邻区牙医数目与儿童恒牙龋病发生率。
本研究旨在探讨社区牙医数量对儿童恒牙龋发病率的影响。该队列于2010年(T1)开始,在巴西南部随机抽取639名儿童(1至5岁),随访7年。随访再评估(T2)于2017年进行。在T2时通过龋面指数(DMF-S)评估未治疗的龋。该社区的牙医数量是从该市的官方数据库中获得的,并用作上下文变量。在T1时评估个体水平上的社会经济、人口统计学和口腔健康变量。采用多水平泊松回归来评估预测变量对未治疗龋发病率的影响。639名T1期儿童中,449名在T2期重新评估(保留率为70.3%)。T2时腐烂表面的平均值为0.92 (SE 0.01)。儿童居住的社区牙医越多,龋齿的发病率就越低。社会经济地位较低的儿童,在过去6个月内没有定期去看牙医,有过龋齿经历,父母认为他们的口腔健康状况一般/较差,出现未经治疗的龋齿的发生率较高。综上所述,居住在牙医较少的社区的儿童患未经治疗的恒牙龋齿的发生率较高。
