Abstract

Resin based dental composites offer significant benefits with regard to the minimally invasive management of dental caries. However, over a period of time such restorations may become susceptible to failure with secondary caries and marginal deterioration being common causes. A retrospective clinical study was conducted at the IMU University Oral Health Centre to assess the quality of direct resin composite restorations placed by dental undergraduates as judged by the modified United States Public Health Service (USPHS), criteria. This study aimed to evaluate the quality and the causes of the failure of direct resin composite restorations in permanent teeth placed by dental undergraduate students using modified USPHS criteria to assess failure. A total of 76 restorations were evaluated in this study. Descriptive statistics were collected, and the Chi-square test (p < 0.05) was used to determine statistically significant differences. A total of 42.1% of the composite resin restorations in the study were considered satisfactory. Of the restorations regarded as failures, the causes were colour mismatch (39.4%), followed by marginal discolouration (21%) and then restoration fracture (14.5%). The operator's year of study (p = 0.039) and the number of restoration surfaces (p = 0.039) showed statistically significant associations with the quality of the restorations. Composite resin restorations performed by dental undergraduates exhibited high failure rates, which were primarily attributed to colour mismatches, marginal dis-colourations, or fractures of the restoration.

对大学生进行直接复合修复的5年临床评估结果。
树脂基牙科复合材料在龋齿的微创治疗方面提供了显著的好处。然而,经过一段时间,这种修复可能变得容易失败,继发性龋齿和边缘退化是常见的原因。IMU大学口腔健康中心进行了一项回顾性临床研究,根据修订的美国公共卫生服务(USPHS)标准评估牙科本科生放置的直接树脂复合修复体的质量。本研究旨在利用改良的USPHS标准评估牙科本科生固定恒牙直接树脂复合材料修复体失败的质量和原因。本研究共评估了76个修复体。进行描述性统计,卡方检验(p
