This study aimed to assess the impact of use of and need for dental prosthesis (DP) on oral health related quality of life (OHRQoL) among Brazilian adults and elders.
This cross-sectional, population-based study, used data from the Brazilian Oral Health National Survey performed in 2010. The sample was representative of adults (35-44 years of age) and elders (65-74 years) at national level. Oral Impact on Daily Performance (OIDP) questionnaire was used to assess the individuals' OHRQoL. Interest variables included use of and need for DP and location of tooth losses. Covariates included socioeconomic, behavioral and clinical characteristics. Associations were performed using Negative Binomial regression models, estimating the rate ratios (RR) and respective 95% confidence intervals.
From the total of 17,398 individuals evaluated, 68.3% needed some type of DP, while the prevalence of DP usage was 49.2%. After adjustments, those needing prosthesis, regardless of already using prosthesis presented an impact more than 50% higher on OHRQoL, and those needing a greater the number of teeth to be replaced and those presenting losses on anterior and posterior regions had higher impact on OHRQoL.
These findings suggest that improvement of strategies focused on oral rehabilitation of adults and elders are crucial to promote population oral health.
The high prevalence of normative need for prosthetic rehabilitation in adult and elder Brazilian population impacts significantly on oral health-related quality of life highlighting the importance of providing prosthetic oral rehabilitation in this population.
本研究旨在评估巴西成年人和老年人使用假牙（DP）及对假牙的需求对口腔健康相关生活质量（OHRQoL）的影响。
本项基于人群的横断面研究使用了2010年巴西口腔健康全国调查的数据。该样本在国家层面代表了成年人（35 - 44岁）和老年人（65 - 74岁）。使用日常口腔功能影响（OIDP）问卷来评估个体的OHRQoL。感兴趣的变量包括假牙的使用和需求以及牙齿缺失的位置。协变量包括社会经济、行为和临床特征。使用负二项回归模型进行关联分析，估计率比（RR）和相应的95%置信区间。
在总共评估的17398名个体中，68.3%需要某种类型的假牙，而假牙的使用率为49.2%。调整后，那些需要假牙的人，无论是否已经使用假牙，对OHRQoL的影响都高出50%以上，并且那些需要更换更多牙齿的人和在前部和后部区域有牙齿缺失的人对OHRQoL的影响更大。
这些发现表明，改进针对成年人和老年人口腔修复的策略对于促进人群口腔健康至关重要。
巴西成年和老年人群中假牙修复的规范需求患病率较高，对口腔健康相关生活质量有显著影响，突出了在该人群中提供口腔修复的重要性。
