The effect of 0.2% chlorhexidine mouth wash (Hexidine) on the plaque microflora was evaluated on children wearing intra oral removable appliances. Plaque samples were collected from the enamel sections, both primary and permanent, mounted on the removable appliances. These appliances were worn by 12 children for one week. Plaque was allowed to accumulate on the in situ test sites and on the adjacent natural dentition. At the end of the experimental period the plaque microflora associated with the enamel sections were compared with that obtained from lingual and interproximal areas of the lower molar teeth. It was also compared with a control group of 12 children without an appliance. In addition, the effect of 0.2% chlorhexidine mouth wash on the plaque microflora for the next 14 days was also determined on both the groups. Although some quantitative difference was found between the proportion of isolates obtained from the different enamel surfaces, it was not statistically significant. There was a statistically significant increase in the isolates of plaque microflora after the insertion of removable appliance in children which decreased significantly with the use of 10 ml of 0.2% chlorhexidine gluconate mouth wash twice a day. The study indicates that the primary and permanent tooth specimens mounted on the intra-oral device collected plaque microflora similar to that present on the adjacent natural dentition and that chlorhexidine gluconate mouth wash therapy is effective in reducing plaque microflora in children with removable appliances.
评估了0.2%氯己定漱口水（洗必泰）对佩戴口腔内可摘矫治器儿童牙菌斑微生物群的影响。从安装在可摘矫治器上的乳牙和恒牙牙釉质部分采集牙菌斑样本。12名儿童佩戴这些矫治器一周。使牙菌斑在原位测试部位和相邻的天然牙列上积聚。在实验期结束时，将与牙釉质部分相关的牙菌斑微生物群与从下颌磨牙舌侧和邻面区域获得的微生物群进行比较。还与12名未佩戴矫治器的儿童组成的对照组进行了比较。此外，还在两组中测定了0.2%氯己定漱口水在接下来14天对牙菌斑微生物群的影响。尽管从不同牙釉质表面获得的分离菌比例存在一些数量差异，但无统计学意义。儿童佩戴可摘矫治器后，牙菌斑微生物群的分离菌有统计学意义的增加，而每天使用两次10毫升0.2%葡萄糖酸氯己定漱口水后，分离菌显著减少。该研究表明，安装在口腔内装置上的乳牙和恒牙标本采集的牙菌斑微生物群与相邻天然牙列上的相似，且葡萄糖酸氯己定漱口水疗法对减少佩戴可摘矫治器儿童的牙菌斑微生物群有效。
