The aim of this study was to compare MTA with another base material, IRM, which is generally used on pulpal floor after root canal treatment, regarding their effect on the success of root canal treatment of primary teeth with furcation lesions. Fifty primary teeth with furcation lesions were divided into 2 groups. Following root canal treatment, the pulpal floor was coated with MTA in the experimental group and with IRM in the control group. Teeth were followed up considering clinical (pain, pathological mobility, tenderness to percussion and palpation, and any soft tissue pathology and sinus tract) and radiographical (pathological root resorption, reduced size or healing of existing lesion, and absence of new lesions at the interradicular or periapical area) criteria for 18 months. For the statistical analysis, Fisher's exact test and Pearson's chi-square tests were used and a value of <0.05 was considered to be statistically significant. Although there were no statistically significant differences between two groups in terms of treatment success, lesions healed significantly faster in the MTA group. In primary teeth with furcation lesions, usage of MTA on the pulpal floor following root canal treatment can be a better alternative since it induced faster healing.
本研究的目的是比较MTA与另一种常用的垫底材料IRM（在根管治疗后用于髓室底）对患有根分叉病变的乳牙根管治疗成功率的影响。50颗患有根分叉病变的乳牙被分为两组。根管治疗后，试验组的髓室底用MTA覆盖，对照组用IRM覆盖。根据临床标准（疼痛、病理性松动、叩诊和触诊压痛以及任何软组织病变和窦道）和影像学标准（病理性牙根吸收、现有病变的缩小或愈合以及根分叉或根尖区无新病变）对牙齿进行18个月的随访。在统计分析中，使用了Fisher精确检验和Pearson卡方检验，P值<0.05被认为具有统计学意义。虽然两组在治疗成功率方面没有统计学上的显著差异，但MTA组的病变愈合明显更快。在患有根分叉病变的乳牙中，根管治疗后在髓室底使用MTA可能是一个更好的选择，因为它能促进更快的愈合。
