The purpose of this study was to evaluate the microbial reduction in deciduous molars using juice (MCJ) as irrigating solution.
This was a randomized comparative study including 60 deciduous molars chosen among the patients belonging to the age group of 6-9 years based on the inclusion or exclusion criteria. The selected teeth were divided randomly into two groups based on irrigation solution used, that was, Group I (1% NaOCl) and Group II (MCJ). The microbial samples were collected both pre- and post-irrigation and were transferred for microbial assay. Paired -test was used for intragroup analysis of pre- and post-operative mean reduction of bacterial colony forming unit (CFU)/ml, whereas Independent -test was used to assess the intergroup, pre- and post-operative mean reduction of bacterial CFU/ml.
In the intragroup comparison, both of the groups showed statistically significant ( < 0.001) reduction in the mean CFU/ml; however, it did not show statistically significant reduction when intergroup comparison was carried out between the two groups. Both the study materials had clinically revealed decrease in the microbial count postirrigation.
Both the irrigants, 1% NaOCl and MCJ, were significantly effective in the reduction of mean CFUs/ml postoperatively. The results of this study have confirmed the antibacterial effectiveness of MCJ in the root canals of deciduous teeth. Considering the low toxicity and antibacterial effectiveness of MCJ, it can be advocated as a root canal irrigant in endodontic treatment of primary teeth.
本研究的目的是评估使用果汁(MCJ)作为冲洗液时乳牙中微生物数量的减少情况。
这是一项随机对照研究,根据纳入或排除标准,从6 - 9岁年龄组的患者中选取60颗乳牙。根据所使用的冲洗液,将所选牙齿随机分为两组,即第一组(1%次氯酸钠)和第二组(MCJ)。在冲洗前后均采集微生物样本并送去进行微生物检测。配对t检验用于组内术前和术后细菌菌落形成单位(CFU)/毫升平均减少量的分析,而独立t检验用于评估两组间术前和术后细菌CFU/毫升的平均减少量。
在组内比较中,两组的平均CFU/毫升均显示出具有统计学意义的降低(P < 0.001);然而,两组之间进行组间比较时,未显示出具有统计学意义的降低。两种研究材料在临床上均显示冲洗后微生物数量减少。
两种冲洗剂,1%次氯酸钠和MCJ,在术后降低平均CFU/毫升方面均显著有效。本研究结果证实了MCJ在乳牙根管中的抗菌效果。考虑到MCJ的低毒性和抗菌效果,它可被推荐作为乳牙牙髓病治疗中的根管冲洗剂。
