The aim of this retrospective practice-based study was to investigate the longevity of direct restorations placed by a group of general dental practitioners (GDPs) and to explore the effect of practice/operator, patient, and tooth/restoration related factors on restoration survival.
Electronic Patient Files of 24 general dental practices were used for collecting the data for this study. From the patient files, longevity of 359,548 composite, amalgam, glass-ionomer and compomer placed in 75,556 patients by 67 GDPs between 1996 and 2011 were analyzed. Survival was calculated from Kaplan-Meier statistics.
A wide variation in annual failure rate (AFR) exists between the different dental practices varying between 2.3% and 7.9%. Restorations in elderly people (65 years and older, AFR 6.9%) showed a shorter survival compared to restorations placed in patients younger than 65 years old (AFR 4.2%-5.0%). Restorations in molar teeth, multi-surface restorations and restorations placed in endodontically treated teeth seemed to be more at risk for re-intervention.
The investigated group of GDPs place restorations with a satisfactory longevity (mean AFR 4.6% over 10 years), although substantial differences in outcome between practitioners exist. Several potential risk factors on practice/operator, patient, and tooth/restoration level have been identified and require further multivariate investigation.
本项基于实践的回顾性研究旨在调查一组普通牙科医生(GDPs)进行的直接修复体的使用寿命,并探讨实践/操作者、患者以及牙齿/修复体相关因素对修复体存留率的影响。
本研究使用了24家普通牙科诊所的电子患者档案来收集数据。从患者档案中,分析了1996年至2011年间67位GDPs为75556名患者放置的359548颗复合树脂、汞合金、玻璃离子体和复合体修复体的使用寿命。通过Kaplan-Meier统计量计算存留率。
不同牙科诊所之间的年失败率(AFR)存在很大差异,在2.3%至7.9%之间。与65岁及以上老年人的修复体(AFR为6.9%)相比,65岁以下患者的修复体存留时间较短(AFR为4.2%-5.0%)。磨牙的修复体、多面修复体以及根管治疗后牙齿上的修复体似乎再次干预的风险更高。
尽管从业者之间的结果存在显著差异,但所调查的GDPs组放置的修复体具有令人满意的使用寿命(10年平均AFR为4.6%)。已确定了实践/操作者、患者以及牙齿/修复体层面的几个潜在风险因素,需要进一步进行多变量研究。
