The study was designed to evaluate an advertising claim made for a commercial pre-brushing mouthrinse, that it aided plaque removal. Forty-one subjects completed a six month, randomised, two-group, blind, pragmatic clinical trial. Those in the control group continued with their normal oral hygiene practices whilst those in the study group were given supplies of the test rinse and asked to use it in accordance with the manufacturer's instructions. Mean plaque scores recorded in the test group after one month, three months and six months, were statistically significantly lower than in the control group supporting the claim made on behalf of the test product. The clinical significance of these findings, for example on gingivitis, is uncertain and further research is needed to assess this.
该研究旨在评估一种商用刷牙前含漱液所宣称的广告效果，即它有助于去除牙菌斑。41名受试者完成了一项为期6个月的随机、两组、盲法、实用性临床试验。对照组受试者继续其正常的口腔卫生习惯，而研究组受试者则获得了测试含漱液，并被要求按照制造商的说明使用。测试组在1个月、3个月和6个月时记录的平均牙菌斑分数在统计学上显著低于对照组，这支持了代表测试产品所宣称的效果。这些发现对于例如牙龈炎的临床意义尚不确定，需要进一步研究来评估这一点。
