The aims of the present study were to evaluate oral health status among Brazilian adults aged 35 to 44 years with regard to functional dentition based on four different definitions and classify dentition configurations using a dental functional status classification system.
The sample was composed of 9564 individuals who participated in the 2010 National Oral Health Survey. The definitions were "well-distributed teeth" concept (WDT), the World Health Organization functional dentition concept (FDWHO), functional dentition classified by esthetics and occlusion (FDClass5), and functional dentition classified by esthetics, occlusion, and periodontal status (FDClass6). Dentitions were classified on six sequential, accumulative levels (anyone reaching level VI necessarily met the criteria on all previous levels): I-≥one tooth in each arch; II-≥10 teeth in each arch (WDT) or ≥20 teeth present (FDWHO); III-all 12 anterior teeth present; IV-≥3 premolar posterior occluding pairs (POPs) present; V-≥one molar POP bilaterally (FDClass5); VI-all sextants with Community Periodontal Index <3 and/or loss of attachment ≤1 (FDClass6).
The prevalence rates of the different definitions of functional dentition ranged from 42.6 % (FDClass5) and 40.3 % (FDClass6) to 72.9 % (WDT) and 77.9 % (FDWHO).
The oral health status of Brazilian adults exhibited considerable variation due to the different definitions of functional dentition, and less than half of Brazilian adults met all the criteria of function.
The indication and planning of prosthetic rehabilitation should not only be based on the absence of teeth but also the distribution and periodontal status of the teeth present.
本研究的目的是基于四种不同定义评估35至44岁巴西成年人的口腔健康状况，这些定义涉及功能性牙列，并使用牙齿功能状态分类系统对牙列构型进行分类。
样本由9564名参与2010年全国口腔健康调查的个体组成。这些定义包括“牙齿分布良好”概念（WDT）、世界卫生组织功能性牙列概念（FDWHO）、按美学和咬合分类的功能性牙列（FDClass5）以及按美学、咬合和牙周状况分类的功能性牙列（FDClass6）。牙列按六个连续的累积水平进行分类（任何达到VI级的人必然满足所有先前水平的标准）：I - 每个牙弓至少一颗牙齿；II - 每个牙弓至少10颗牙齿（WDT）或至少存在20颗牙齿（FDWHO）；III - 所有12颗前牙均存在；IV - 至少存在3对前磨牙后牙咬合对（POPs）；V - 双侧至少一对磨牙POP（FDClass5）；VI - 所有牙区社区牙周指数<3和/或附着丧失≤1（FDClass6）。
功能性牙列不同定义的患病率从42.6%（FDClass5）和40.3%（FDClass6）到72.9%（WDT）和77.9%（FDWHO）不等。
由于功能性牙列的不同定义，巴西成年人的口腔健康状况表现出相当大的差异，并且不到一半的巴西成年人满足所有功能标准。
修复性康复的指征和计划不仅应基于牙齿的缺失情况，还应基于现有牙齿的分布和牙周状况。
