目的：评价树脂基复合材料(RBC)修复体在恒牙中放置和更换的原因，并确定更换修复体的寿命。方法：研究人群包括2480名参加私人诊所的人。临床检查包括评估龋齿(乳牙)和失败修复体的数量，以及放置和更换RBC修复体的原因。此外，还评估了修复体的放置和更换与空洞类型之间的可能联系，以及按牙齿类型放置和更换RBC修复体的原因。统计分析采用卡方检验。结果：共鉴定3,528个修复体，其中2,046个(58%)为首次修复，1,482个(42%)为替换修复体。首次RBC修复的主要原因是原发龋病(56%)。继发性龋病是更换RBC修复体的最常见原因(43%)。窝洞类型与首次修复(P=0.0083)、置换修复(P=0.0067)相比，差异有统计学意义。牙齿类型与首次(P=0.067)或更换(P=0.073)原因的差异无统计学意义。更换修复体的中位寿命约为4年(39%)。结论：原发龋病和继发性龋病是初次修复和置换修复的主要原因，其次是牙齿变色和修复变色。因此，患龋齿的高危患者可能需要更频繁的牙齿护理。
Objectives: The aims of the present study were to assess the reasons for the placement and replacement of resin-based composite (RBC) restorations in permanent teeth and to establish the longevity of replaced restorations. Methods: The study population consisted of 2,480 individuals attending a private practice. Clinical examination involved the evaluation of the numbers of decayed teeth (primary caries) and failed restorations, respectively, and the reasons for the placement and replacement of RBC restorations. In addition, possible associations between the placement and replacement of restorations and type of cavity, and the reasons for the placement and replacement of RBC restorations by tooth type were assessed. Statistical analysis was accomplished using the chi-squared test. Results: A total of 3,528 restorations were identified; 2,046 (58%) of these were first-time restorations and 1,482 (42%) were replacement restorations. The main reason for first-time RBC restorations was primary caries (56%). Secondary caries was the most frequent reason for the replacement of RBC restorations (43%). Statistically significant differences were recorded between cavity type and first-time (P = 0.0083) and replacement (P = 0.0067) restorations. No statistically significant differences were observed between tooth type and the reasons for first-time (P = 0.067) or replacement (P = 0.073) RBC restorations. The median longevity of replaced restorations was approximately 4 years (39%). Conclusions: Primary and secondary dental caries were the principle reasons for first-time and replacement restorations, followed by tooth and restoration discolouration, respectively. Therefore, patients at high risk for developing caries may require more frequent dental care.
