To evaluate the contribution of the psychosocial and behavioral aspects of pain to the perception of oral health in a sample of Brazilian dental patients.
This cross-sectional study involved 436 patients who sought dental care in the School of Dentistry of São Paulo State University and who reported some type of orofacial pain. The study group's mean age (± standard deviation [SD]) was 39.9 ± 13.6 years, and the sample was 74.5% female. The Portuguese version of the Oral Health Impact Profile Short Form (OHIP-14) and the Multidimensional Pain Inventory (MPI) were used. The data were included in a structural equation model in which perception of oral health was considered the dependent variable. The evaluation of the contribution of psychosocial and behavioral aspects of pain to the perception of oral health was based on the statistical significance of causal paths (β) evaluated by z tests (α = 5%).
The fit of the models of OHIP-14 and MPI were adequate. Interference, self-control, negative mood, and punishing responses provided significant contributions to the perception of oral health. The structural model presented adequate fit to the data (explained variance = 28.0%).
These findings provide evidence that psychosocial and behavioral aspects of pain such as interference of pain in activities, self-control, negative mood, and punishing responses contribute to the perception of oral health.
评估巴西牙科患者样本中疼痛的心理社会和行为方面对口腔健康感知的贡献。
本横断面研究纳入了 436 名在圣保罗州立大学牙科学院寻求牙科治疗并报告存在某种类型的颌面疼痛的患者。研究组的平均年龄（±标准差）为 39.9±13.6 岁，样本中 74.5%为女性。使用了葡萄牙语版口腔健康影响量表简表（OHIP-14）和多维疼痛问卷（MPI）。数据被纳入结构方程模型中，其中口腔健康感知被视为因变量。基于 z 检验（α=5%）评估因果路径（β）的统计学意义来评估疼痛的心理社会和行为方面对口腔健康感知的贡献。
OHIP-14 和 MPI 模型的拟合度良好。干扰、自我控制、负性情绪和惩罚性反应对口腔健康感知有显著贡献。结构模型对数据的拟合度良好（解释方差=28.0%）。
这些发现提供了证据表明疼痛的心理社会和行为方面，如疼痛对活动的干扰、自我控制、负性情绪和惩罚性反应，有助于口腔健康感知。
