Abstract
Recently, problems have occurred frequently such as cervical and exposed dentin surface lesions or root caries and subsequent hypersensitivity because of further increase of the elderly population. This study was projected to device a proper and simple treatment and materials for the adhesive composite restoration for such lesions. The 10-20Ca (10% citric acid containing 20% calcium chloride) solution was found to be a comparatively mild tooth surface conditioning agent and to be effective with a single application to both dentin and enamel. In addition, the use of the SA primer (3% N-methacryloyl 5-aminosalicylic acid in 80% ethanol) and the LVR (visible light-cured, 33% microfilled low viscous Bis-GMA resin) dramatically improved the adhesion and adaptability of the composite restoration in the saucer cavity at the cervical area.
近年来，由于老年人口的进一步增加，经常出现颈椎及外露牙本质表面病变或牙根龋及继发的过敏等问题。本研究旨在为此类病变提供一种合适且简单的治疗方法和材料。10-20Ca(10%柠檬酸含20%氯化钙)溶液被发现是一种相对温和的牙齿表面调理剂，对牙本质和牙釉质都有效。此外，SA底漆(3% n -甲基丙烯酰5-氨基水杨酸，80%乙醇)和LVR(可见光固化，33%微填充低粘性Bis-GMA树脂)的使用显著提高了复合修复体在颈部托腔内的粘附性和适应性。
