The oral health benefits of a prebrushing rinse, when used in conjunction with an established twice-a-day brushing regimen, was investigated in a population of orthodontic patients. Twenty children (ages 11-18) who were undergoing orthodontic treatment that required brackets and labial wires were enrolled. This randomized, double-blind, cross-over clinical trial compared five weeks of twice-daily use of a commercial prebrushing rinse (Plax) to five weeks of a placebo rinse. Three investigators rated plaque accumulation (Simplified Oral Hygiene Index) and gingival health (modified O'Leary Index) prior to treatment and after each five week session. Because one child exited from the project and three children did not satisfactorily comply with the treatment protocol, sixteen children were used for the analysis. Although both treatment groups showed plaque and gingival improvement from pretreatment scores, no differences in plaque accumulation ratings and gingival health ratings were noted between the active and placebo rinse treatments.
在一组正畸患者中，研究了在每日两次的既定刷牙方案基础上使用刷牙前漱口液对口腔健康的益处。招募了20名正在接受需要使用托槽和唇弓的正畸治疗的儿童（年龄11 - 18岁）。这项随机、双盲、交叉临床试验将每日两次使用市售刷牙前漱口液（Plax）的五周时间与使用安慰剂漱口液的五周时间进行了比较。三名研究人员在治疗前以及每五周疗程结束后对牙菌斑积聚情况（简化口腔卫生指数）和牙龈健康状况（改良奥利里指数）进行了评分。由于一名儿童退出了该项目，三名儿童未令人满意地遵守治疗方案，因此使用16名儿童进行分析。尽管两个治疗组的牙菌斑和牙龈状况与治疗前评分相比均有改善，但在活性漱口液治疗组和安慰剂漱口液治疗组之间，未观察到牙菌斑积聚评分和牙龈健康评分存在差异。
