This article reports the results of an analysis to determine the relationships between the quality of restorative dental care for 1,466 patients and 9 categories of dentist characteristics for 102 volunteer Washington practitioners. In this study, patients were recalled and restorations were examined clinically. Questionnaires were administered to patients and dentists. The dependent measure is a weighted average of scores for operative dentistry and crown and bridge. Stagewise regression was used to adjust for differences in patient oral health and assessor bias. Models were postulated in each category of dentist characteristics and beta vectors were estimated by multiple regression. The best predictors formed a significant model (p = 0.000) which explained 26 per cent of the variance.
本文报告了一项分析结果，该分析旨在确定1466名患者的牙齿修复护理质量与102名华盛顿州志愿从业者的9类牙医特征之间的关系。在这项研究中，召回患者并对修复体进行临床检查。同时向患者和牙医发放问卷。因变量是牙体牙髓病学以及冠桥修复评分的加权平均值。采用逐步回归法来调整患者口腔健康的差异以及评估者偏差。针对每一类牙医特征建立模型，并通过多元回归估计β向量。最佳预测指标构成了一个显著模型（p = 0.000），该模型解释了26%的方差。
