To assess whether coverage of an untreated or restored carious root lesion with a subepithelial connective tissue graft would provide a predictable, esthetically acceptable result and prevent further caries progression.
Twenty-seven teeth from 13 patients with root caries and gingival recessions of 3.4 +/- 0.2 mm (mean +/- SEM) were treated with subepithelial connective tissue grafts. Eighteen teeth had untreated caries, and the other nine had composite or glass-ionomer restorations. The carious dentin and the plastic restorations were removed prior to the surgical procedure. The exposed roots were thoroughly planed and covered by a subepithelial connective graft with no further root treatment or conditioning. The teeth were examined periodically from 1-6 years post-treatment for retention of root surface coverage and presence of carious lesions.
The mean root coverage recession left after the treatment was 0.3 +/- 0.1 mm, with coverage of 92.4 +/- 2.4%. Significant differences (P< 0.05) were found between the coverage of roots with carious lesions that had not been restored and those that had restorations removed. However, since the number of teeth with restorations was limited, further study is required to confirm this difference. In 18 cases, complete coverage of the recession was achieved. The results were stable, and no further recessions or recurrent caries were detected.
评估用上皮下结缔组织移植覆盖未治疗或已修复的龋坏牙根病变是否能提供可预测的、美学上可接受的结果，并防止龋齿进一步发展。
对13例患有牙根龋和牙龈退缩（平均3.4±0.2mm，均值±标准误）的患者的27颗牙齿进行上皮下结缔组织移植治疗。18颗牙齿有未治疗的龋齿，另外9颗有复合树脂或玻璃离子修复体。在手术前去除龋坏牙本质和塑料修复体。将暴露的牙根彻底平整，并用上皮下结缔组织移植物覆盖，不再进行进一步的牙根治疗或预处理。在治疗后1至6年定期检查牙齿，观察牙根表面覆盖情况及龋损的存在情况。
治疗后牙根覆盖退缩的平均值为0.3±0.1mm，覆盖率为92.4±2.4%。未修复的龋坏牙根与已去除修复体的牙根在覆盖率上存在显著差异（P<0.05）。然而，由于有修复体的牙齿数量有限，需要进一步研究来证实这种差异。18例实现了退缩的完全覆盖。结果稳定，未检测到进一步的退缩或复发性龋齿。
