目的：评价磷酸选择性釉质酸蚀自酸蚀底漆系统和一瓶粘接剂系统5年的临床应用效果。方法：8例宫颈非龋损患者(男4例，女4例)，年龄45~78岁，平均61.3岁。将牙釉质倒角和牙本质轻轻研磨，然后使用Clearff衬里粘结剂(LB11)或单一粘结剂(SB)结合混合树脂复合材料(ClearferAP-X)修复洞洞。对27个窝洞，用37%磷酸对牙釉质进行10次S预处理，随机分配两种修复方法。所有修复体(LB型37个，SB型35个)均由一名牙医放置。5年后采用改良的USPHS标准进行盲法评价。结果：5年后，除1个修复体(召回2年后更换为全冠)外，其余修复体均得到评价。两组修复体的固位率均为100%。未发现与任何修复体相关的龋齿。唯一的小问题是边缘变色；大约18%的修复体发生了表面和局部的边缘变色，主要发生在牙本质边缘。LB组和SB组边缘完整性无明显差异。结论：本研究使用的修复材料具有良好的临床应用价值。宫颈非龋性病变修复5年疗效观察(C)2005爱思唯尔有限公司。保留所有权利。
Objective: This controlled clinical trial evaluated the 5-year clinical performance of a self-etching primer system including selective enamel-etching with phosphoric acid and a one-bottle adhesive system.Methods: Seventy-two non-carious cervical lesions in 8 patients (4 mate and 4 female) with a mean age of 61.3 years (range 45-78) participated in the study. An enamel bevel was placed and dentin lightly ground, and cavities restored with clearfil liner bond 11 (LB) or single bond (SB) in conjunction with a hybrid resin composite (Clearfil AP-X). In the case of 27 cavities for LB, the enamel was pretreated with 37% phosphoric acid for 10 s. Each patient received both types of restoration, which were distributed on a random basis. All restorations (37 restorations for LB and 35 restorations for SB) were placed by one dentist. The restorations were evaluated blind after 5 years using modified USPHS criteria. The data were statistically analyzed using the Fisher's exact test.Results: All but one restoration (which was replaced by a crown after the 2-year recall) were evaluated after 5 years. 100% retention rates were recorded for both restorative groups. No caries was detected in association with any restorations. The only minor problem was marginal discoloration; superficial and localized marginal discoloration occurred around 18% of the restorations, and mainly at the dentin margin. There were no significant differences in the marginal integrity between the LB and SB groups.Conclusions: Restorative materials used in this study demonstrated a good clinical. effectiveness in the restoration of non-carious cervical lesions for 5 years.
