The aim of this cross-sectional in vivo study was to assess the effect of green tea and honey solutions on the level of salivary Streptococcus mutans.
A convenient sample of 30 Saudi boys aged 7-10 years were randomly assigned into 2 groups of 15 each. Saliva sample was collected for analysis of level of S. mutans before rinsing. Commercial honey and green tea were prepared for use and each child was asked to rinse for two minutes using 10 mL of the prepared honey or green tea solutions according to their group. Saliva samples were collected again after rinsing. The collected saliva samples were prepared and colony forming unit (CFU) of S. mutans per mL of saliva was calculated.
The mean number of S. mutans before and after rinsing with honey and green tea solutions were 2.28* 10(8)(2.62210(8)), 5.64 10(7)(1.0310(8)), 1.1710(9)(2.01210(9)) and 2.5910(8) (3.668*10(8)) respectively. A statistically significant reduction in the average number of S. mutans at baseline and post intervention in the children who were assigned to the honey (P=0.001) and green tea (P=0.001) groups was found.
A single time mouth rinsing with honey and green tea solutions for two minutes effectively reduced the number of salivary S. mutans of 7-10 years old boys.
本横断面体内研究旨在评估绿茶和蜂蜜溶液对唾液变形链球菌水平的影响。
选取30名年龄在7至10岁的沙特男孩作为便利样本,随机分为两组,每组15人。在漱口前收集唾液样本以分析变形链球菌水平。准备好市售蜂蜜和绿茶以供使用,要求每个孩子根据其所在组使用10毫升制备好的蜂蜜或绿茶溶液漱口两分钟。漱口后再次收集唾液样本。对收集到的唾液样本进行处理,并计算每毫升唾液中变形链球菌的菌落形成单位(CFU)。
用蜂蜜和绿茶溶液漱口前后变形链球菌的平均数量分别为2.28×10⁸(2.622×10⁸)、5.64×10⁷(1.03×10⁸)、1.17×10⁹(2.012×10⁹)和2.59×10⁸(3.668×10⁸)。在分配到蜂蜜组(P = 0.001)和绿茶组(P = 0.001)的儿童中,发现基线和干预后变形链球菌的平均数量有统计学意义的减少。
用蜂蜜和绿茶溶液单次漱口两分钟可有效减少7至10岁男孩唾液中变形链球菌的数量。
