Twenty-five subjects with a total of 50 subgingival restorations participated in this study. At the beginning of the investigation, nine teeth that were considered hopeless because of the extent of their pathology were selected for extraction to evaluate histologically the restorations and their effect on the adjacent tissues. The purpose of this article is to demonstrate the responses to the clinical applications as well as to the placement of resin-ionomers in subgingival lesions. Clinical and histologic evidence of epithelial and connective tissue adherence to resin-ionomer restorative materials was observed during the healing process.
25名受试者共有50个龈下修复体参与了本研究。在调查开始时，选择了9颗因病变程度而被认为无可挽救的牙齿进行拔除，以便从组织学上评估修复体及其对相邻组织的影响。本文的目的是展示对临床应用以及树脂离子体在龈下病变中的放置的反应。在愈合过程中观察到上皮和结缔组织附着于树脂离子体修复材料的临床和组织学证据。
