Abstract

Objective: To find out the effectiveness of catechin extract of green tea (Camellia sinensis) on Porphyromonas gingivalis. Material and Methods: The independent variables were catechin extracts of green tea (Camellia sinensis) starting from the 40%, 20%, 10%, 5%, 2.5% and 1.2% concentrations. The dependent variables were the Minumum Inhibitory Concentration (MIC) and the Inhibition zone of bacterial growth of Porphyromonas gingivalis. Control variables were time, culture medium, and temperature. The sample of research were Porphyromonas gingivalis which has been bred and catechin extract of green tea (Camellia sinensis) that extracted by maceration method. of research were Porphyromonas gingivalis which has been bred and catechin extract of green tea (Camellia sinensis) that extracted by maceration method.. Results: At the 40%, 20%, 10%, and 5% concentrations, the growth of Porphyromonas gingivalis did not change. As for the 2.5% and 1.25% concentrations, bacterial growth has occurred. Conclusion: Catechin extract of green tea (Camellia sinensis) was effective in inhibition of Porphyromonas gingivalis.

绿茶儿茶素提取物对牙龈卟啉单胞菌的疗效观察

目的:观察绿茶儿茶素提取物对牙龈卟啉单胞菌的治疗效果。材料与方法:自变量为40%、20%、10%、5%、2.5%、1.2%浓度的绿茶儿茶素提取物。因变量为最小抑制浓度(MIC)和对牙龈卟啉单胞菌生长的抑制带。控制变量为时间、培养基和温度。研究对象为已养殖的牙龈卟啉单胞菌和浸渍法提取的绿茶儿茶素。研究对象为已培育的牙龈卟啉单胞菌和浸渍法提取的绿茶儿茶素。结果:在40%、20%、10%和5%的浓度下，牙龈卟啉单胞菌的生长没有变化。在2.5%和1.25%的浓度下，细菌发生了生长。结论:绿茶儿茶素提取物对牙龈卟啉单胞菌有较好的抑制作用。
