【摘要】 目的 探讨光固化复合体Dyract在牙楔状缺损修复中的疗效。方法 将120例楔状缺损患者(284颗患牙)随机分为Dyract组(153颗)和对照组(131颗),对照组患者采用光固化复合树脂充填,Dyract组患者采用Dyract复合体充填。经6~12个月复查。临床根据修复体、形态、临床症状等以判断疗效。结果 治疗12个月后Dyract组有效率92.35%, 对照组78.65%,Dyract组12例无效中修复体脱落8颗,折断3颗,继发牙髓炎2颗;对照组28例无效中脱落15颗,折断8颗,继发牙髓炎3颗，色泽改变2颗。两者临床疗效差异有统计学意义(P<0.05)。USPHS评估系统分析则发现2组边缘密合度、边缘着色、修复体脱落方面均有明显差别(P<0.05)。结论 采用光固化复合体修复楔状缺损较光固化复合树脂更理想,简便,容易操作,美观逼真,不变色,是修复楔状缺损的理想材料。

【Abstract】 Objective To investigate light-cured dental composite Dyract wedge-shaped defects in the results. Methods 120 patients with wedge-shaped defect patients (284 teeth) were randomly divided into Dyract group (153) and control group (131), the control group were treated with light-cured composite resin, Dyract group of patients with complex filled with Dyract. After 6~12 months later. According to restoration of clinical, morphological, clinical symptoms to determine efficacy. Results After 12 months Dyract group was 92.35% and the control group was 78.65%, Dyract in 12 cases of in effective restoration off 8 cases, broken 3 cases, secondary to pulpitis 2.In control group, 28 cases were ineffective in shedding 15, broken 8, secondary to pulpitis 3, the color change 2 cases.Statistically significant difference between the clinical efficacy (P<0.05). USPHS evaluation system analysis was found in Group 2 edge adaptation, edge coloring, body off restoration areas were significantly different (P<0.05).Conclusion The light-cured composite wedge-shaped defect repair than the more desirable light-cured composite resin, simple, easy to operate, beautiful and realistic, not color, is an ideal material for wedge-shaped defect repair.

楔状缺损多是临床上常见的牙体硬组织的非龋性疾病, 一般认为是由于长期横向拉锯式的刷牙方法导致的硬组织发生缓慢消耗所致的缺损。多发生于唇、颊侧的牙颈部。楔状缺损在老年人中十分常见，患病率为47.5%~60%[1]。口腔科采用光固化复合树脂与Dyract 复合体充填楔状缺损,充填后6~12个月复查,观察近期疗效 ......
