One of the unfavorable outcomes of endodontic treatment in primary molars is furcal perforation. During treatment, bacterial infection at the site of perforation should be prevented for better prognosis.
This study aims to compare sealing ability of mineral trioxide aggregate (MTA) Plus™ and Biodentine™ for the repair of furcal perforation in primary molars using spectrophotometry.
Access opening was done for all ninety extracted teeth. Perforation was made in furcation area in all the teeth. The sample size consisted of ninety extracted teeth. They were divided into four groups, Group 1 ( = 30) in which perforations were repaired with MTA Plus™, Group 2 ( = 30) in which perforations were repaired with Biodentine™. The other two groups were considered as control groups, Group 3 ( = 15) in which perforations were left unsealed (positive control) and Group 4 ( = 15) without perforations (negative control). Dye extraction method was used to compare the sealing ability of MTA Plus™ and Biodentine™. Statistical analysis was done using ANOVA test to compare the mean between the different groups. Intergroup comparison was performed using Scheffe test.
The highest dye absorbance was seen in the positive control group with a mean value of 0.080 ± 0.033. The mean value of MTA Plus™ was 0.031 ± 0.026 and Biodentine™ was 0.024 ± 0.031.
The mean value of dye absorption of MTA Plus™ was greater than Biodentine™ but it was statistically insignificant.
乳牙根管治疗的不良后果之一是髓室底穿孔。在治疗过程中,应防止穿孔部位的细菌感染以获得更好的预后。
本研究旨在使用分光光度法比较矿物三氧化物凝聚体(MTA)Plus™和生物活性玻璃(Biodentine™)修复乳牙髓室底穿孔的封闭能力。
对所有90颗拔除的牙齿进行开髓。在所有牙齿的根分叉区制作穿孔。样本量包括90颗拔除的牙齿。将它们分为四组,第1组(n = 30)用MTA Plus™修复穿孔,第2组(n = 30)用Biodentine™修复穿孔。另外两组作为对照组,第3组(n = 15)穿孔不封闭(阳性对照),第4组(n = 15)无穿孔(阴性对照)。采用染料提取法比较MTA Plus™和Biodentine™的封闭能力。使用方差分析进行统计分析以比较不同组之间的均值。组间比较采用Scheffe检验。
阳性对照组的染料吸光度最高,均值为0.080±0.033。MTA Plus™的均值为0.031±0.026,Biodentine™的均值为0.024±0.031。
MTA Plus™的染料吸收均值大于Biodentine™,但在统计学上无显著差异。
