This study was conducted to evaluate and compare the antimicrobial efficacy of green tea catechin as a mouth wash on colony count of Streptococcus mutans in children.
A sample size of thirty children was selected out of screened 290 children by simple random sampling between the age group of 7 and 12 years. The study was conducted over a period of 2 weeks. After 24 h of oral prophylaxis, the baseline samples were collected and each group was subjected to mouth rinsing with green tea mouth wash for 2 weeks and further plaque and saliva samples were collected at 1- and 2-week intervals from baseline. Microbiological analysis of plaque and saliva samples was done by Dentocult SM strip kit (Orion Diagnostica, Finland), and the results were statistically analyzed and tabulated.
Statistically, there was highly significant reduction in S. mutans count in plaque as well as in saliva for after 1- and 2-week intervals from baseline.
Hence, finally, our study showed that green tea catechin is effective as a mouth wash against S. mutans and having better action in plaque as compared to saliva. It can be used as an adjunct to commercially available mouthwashes.
本研究旨在评估并比较绿茶儿茶素作为漱口水对儿童变形链球菌菌落计数的抗菌效果。
通过简单随机抽样从290名经过筛选的7至12岁儿童中选取30名作为样本。研究为期2周。在进行口腔预防24小时后，收集基线样本，每组用绿茶漱口水漱口2周，并从基线开始每隔1周和2周进一步收集牙菌斑和唾液样本。牙菌斑和唾液样本的微生物分析采用Dentocult SM试纸条试剂盒（芬兰奥立安诊断公司）进行，结果进行统计分析并制成表格。
从统计学角度来看，与基线相比，在1周和2周后牙菌斑和唾液中的变形链球菌计数均有极显著降低。
因此，最终我们的研究表明，绿茶儿茶素作为漱口水对变形链球菌有效，并且与唾液相比，对牙菌斑的作用更好。它可作为市售漱口水的辅助用品。
