The aim of the study was to compare the antimicrobial efficacy of sodium hypochlorite (NaOCl), Saline, and Er, Cr:YSGG laser-assisted disinfection through microbiological analysis in root canal treatment of primary molars.
Forty-five primary teeth were selected for this study as per the inclusion and exclusion criteria in the age group of 4-8 years and then randomly allocated to Three Groups A, B, and C. In Group A, during root canal treatment, irrigation was done using NaOCl, in Group B, laser-assisted disinfection was done using Er, Cr:YSGG laser, and in Group C, saline was used as an irrigating agent. This was followed by obtaining pre- and postirrigation samples from the canals for microbiological investigation in all the groups. Data analysis was performed using Statistical Package for the Social Science-21 (SPSS-21).
NaOCl was more effective against aerobic bacteria while Er, Cr:YSGG laser was more effective against anaerobic bacteria when used for disinfection in root canal treatment. There was a significant difference among the three groups (P > 0.05).
The study showed that NaOCl and Er, Cr:YSGG laser have antimicrobial effects when used for disinfection in root canal treatment of primary teeth. Moreover, the study also shows that Er, Cr:YSGG laser may be used as a valuable tool for laser-assisted disinfection in root canal treatment of primary teeth.
本研究旨在通过微生物分析比较次氯酸钠(NaOCl)、生理盐水和 Er,Cr:YSGG 激光辅助消毒在儿童乳磨牙根管治疗中的抗菌效果。
根据纳入和排除标准,选择 45 颗年龄在 4-8 岁的乳磨牙进行本研究,并随机分为 A、B、C 三组。在 A 组中,根管治疗时使用 NaOCl 冲洗,在 B 组中,使用 Er,Cr:YSGG 激光进行激光辅助消毒,在 C 组中,使用生理盐水作为冲洗剂。然后在所有组中从根管中获取冲洗前后样本进行微生物学调查。数据分析使用社会科学统计软件包-21(SPSS-21)进行。
NaOCl 对需氧菌更有效,而 Er,Cr:YSGG 激光对厌氧菌更有效,用于根管治疗消毒时。三组之间有显著差异(P > 0.05)。
本研究表明,NaOCl 和 Er,Cr:YSGG 激光在儿童乳磨牙根管治疗消毒中具有抗菌作用。此外,研究还表明,Er,Cr:YSGG 激光可作为儿童乳磨牙根管治疗中激光辅助消毒的有价值工具。
