目的：通过一项前瞻性纵向队列临床研究，探讨树脂基复合材料（RBC）修复体替代治疗的有效性。材料和方法：40例27 ~ 77岁（平均55岁）患者，88例RBC修复体，有一个或多个特征偏离理想，参与研究。他们被分为5个治疗组：修复组（N=25），修复边缘缺损组（N=13），表面修复组（N=18），置换组（N=16）和无治疗组（N=16）。替代组和未治疗组作为对照组，接受随机分配。两名临床医生在指定治疗之前检查修复体的质量（N=88），并在随后的召回（1年和2年）使用修改的Ryge标准（Alfa， Bravo和Charlie，分别表示临床优秀，临床可接受的一个或多个特征偏离理想，临床不可接受）观察(1)颜色，(2)边缘适应性，(3)解剖形式，(4)表面粗糙度，(5)边缘染色，(6)体积变色，(7)接触，(8)继发性龋齿，(9)术后敏感性，（10）光泽。结果：在1年和2年的回顾中，分别检查了66（75%）和58（66%）个修复体。Kruskal-Wallis检验显示1年和2年回忆检查的边际适应和边际染色有显著差异（p < 0.05）。与未治疗组相比，修复组、密封剂组和置换组在边缘适应方面有显著改善。修复组和置换组的边缘染色效果优于未处理组。结论：红细胞修复体边缘适应不理想，边缘染色较好。临床意义：对于边缘适应和边缘染色不充分的RBC修复体，树脂基复合修复体是一种保守的治疗选择。
PURPOSE: To investigate the effectiveness of alternative treatments to the replacement of resin-based composite (RBC) restorations through a prospective longitudinal cohort clinical study.MATERIALS AND METHODS: Forty patients aged 27 to 77 years (mean=55) with 88 RBC restorations, with one or more features that deviated from ideal, participated in the study. They were assigned to five treatment groups: repair (N=25), sealing of defective margins (N=13), resurfacing (N=18), replacement (N=16), and the no-treatment group (N=16). The replacement and no-treatment groups served as comparison groups and received random assignment. Two clinicians examined the quality of the restorations (N=88) prior to the assigned treatment, and at subsequent recalls (1 and 2 years) using a modified Ryge criteria (Alfa, Bravo, and Charlie, meaning clinically excellent, clinically acceptable with one or more features that deviated from ideal, and clinically unacceptable, respectively) that observed (1) color, (2) marginal adaptation, (3) anatomic form, (4) surface roughness, (5) marginal staining, (6) bulk discoloration, (7) contact, (8) secondary caries, (9) postoperative sensitivity, and (10) luster.RESULTS: At 1- and 2-year recalls, 66 (75%) and 58 (66%) restorations were examined. Kruskal-Wallis Test showed significant differences for marginal adaptation and marginal staining for both 1- and 2-year recall exams (p < .05). The repair, sealant, and replacement groups presented significant improvement when compared with the no-treatment group for marginal adaptation. The repair and replacement groups showed superior results when compared with the no-treatment group for marginal staining.CONCLUSION: RBC restorations that present less-than-ideal marginal adaptation and stained margins are better off being repaired.CLINICAL SIGNIFICANCE: Repair of resin-based composite (RBC) restorations is a conservative option for treatment of RBC restorations with inadequate marginal adaptation and marginal staining.
