In Japan, the percentage of root surface caries and hypersensitibity of exposed root surface due to retraction of gum margin in the mouth of the aged people increases constantly accompanying with the increase of population of the aged people. Therefore, this study was designed in order to remove the hypersensitibity of the exposed root surface and additionally protect from cervical and root surface caries. According to the project performed from 1989 through 1991, the following results were found ;The proper clinical procedure was established to remove the hypersensitibity of the exposed root surfaces. Namely, the exposed root surface is treated with IO-2OCa solution and washed with water and dried, and applied with SA solution and dried followed by application of a dual-cure type bonding agent. Then a low viscosity composite resin liner containing 33 weight percent of an organic complex filler particles is painted by a brush and light-cured. At the next appointment the cured liner is finished and polished by a routine technique. This technique and materials showed no pulpal irritation with monkey teeth and removed hypersensitibity completely in the clinical trial. Furthermore, the ultrastructure of the cervical lesion showed the difference from the coronal lesion in structure and progress. In the future, we are planning to incorporate a fluoride into the polymers which is used in the low viscosity composite resin.

在日本，随着老年人口的增加，老年人口腔中因牙龈缘退缩而引起的根面龋和暴露根面过敏的比例不断增加。因此，本研究旨在消除暴露根面的过敏性，并额外防止颈部和根面龋。根据1989年至1991年进行的项目，发现了以下结果：建立了适当的临床程序，以消除暴露根面的过敏。即，用IO-2 OCa溶液处理暴露的牙根表面，用水洗涤并干燥，用SA溶液施加并干燥，然后施加双固化型粘合剂。然后用刷子涂敷含有33wt%有机复合填料颗粒的低粘度复合树脂衬里并光固化。在下一次预约时，通过常规技术对固化的内衬进行精加工和抛光。临床试验表明，该技术和材料对猴牙无刺激性，完全消除了过敏反应。宫颈病变的超微结构与冠状病变在结构和进展上存在差异。未来，我们计划将氟化物加入到用于低粘度复合树脂的聚合物中。
