Three restorative materials used for cervical erosion /abrasion lesions were evaluated clinically after 10 years. Thirty adult patients with at least four cervical lesions received one restoration of each of Ketac-Fil, finished immediately, Ketac-Fil, finished after a delay, Chelon-FIl (all glass-ionomer cements), and Cervident (a resin composite). Restorations were placed without any tooth preparations. Eighteen patients returned for their 10-year examinations. Two experienced examiners provided the periodic evaluations. Complete retention at 10 years was 83% for Ketac-Fil, finished immediately; 78% for Ketac-Fil, finished after a delay; 67% for Chelon-Fil; and 17% for Cervident. All three glass-ionomer restorative materials exhibited statistically significantly greater retention that did Cervident. When a noninvasive procedure is desired, glass-ionomer materials are the restorative material of choice for abrasion/erosion lesions because of their long-term retention values.
三种用于宫颈糜烂/磨损性病变的修复材料在10年后进行了临床评估。30名成年患者至少有四处宫颈病变，分别接受了即刻完成的Ketac-Fil、延迟完成的Ketac-Fil、Chelon-Fil（均为玻璃离子水门汀）和Cervident（一种树脂复合材料）修复，每种修复材料各修复一处。修复时未进行任何牙齿预备。18名患者返回接受10年检查。两名经验丰富的检查人员进行定期评估。即刻完成的Ketac-Fil在10年时的完全保留率为83%；延迟完成的Ketac-Fil为78%；Chelon-Fil为67%；Cervident为17%。所有三种玻璃离子修复材料的保留率在统计学上均显著高于Cervident。当需要无创操作时，由于玻璃离子材料的长期保留值，它们是磨损/侵蚀性病变修复材料的首选。
