This clinical study compared the effect of Colgate Actibrush, a battery-powered toothbrush, and Colgate Plus Diamond Head, a full-head, soft-bristled manual toothbrush, on established supragingival plaque and gingivitis over a 30-day period. Sixty-two healthy adult men and women were entered in the study. The subjects were stratified into two balanced groups according to their mean baseline plaque and gingivitis scores. Each group was randomly assigned to the use of one of the two toothbrushes. Subjects were instructed to brush their teeth at home twice daily (morning and evening) for 1 minute with their assigned toothbrush and a commercially available tooth-paste for the 30-day duration of the study. Gingivitis and plaque examinations, as well as a soft-tissue evaluation, were conducted by the same dental examiner at baseline and after 15 and 30 days of toothbrush use. Plaque and gingivitis scores were reduced significantly from baseline after the use of both toothbrushes for 30 days. However, improvement in both supragingival plaque and gingivitis scores was significantly greater in the group using Colgate Actibrush. In conclusion, although both toothbrushes provided a significant plaque and gingivitis benefit when used as part of a normal oral hygiene regimen, the efficacy of the Colgate Actibrush was demonstrated to be superior to that of the Colgate Plus Toothbrush after 30 days of use.
这项临床研究比较了电动牙刷高露洁Actibrush和全头软毛手动牙刷高露洁倍加钻石刷头牙刷在30天内对已形成的龈上菌斑和牙龈炎的影响。62名健康成年男女参与了该研究。根据他们的平均基线菌斑和牙龈炎评分，将受试者分层为两个均衡的组。每组被随机分配使用两种牙刷中的一种。受试者被指示在研究的30天内，每天在家用指定的牙刷和市售牙膏早晚各刷牙1分钟。在基线以及使用牙刷15天和30天后，由同一位牙科检查人员进行牙龈炎和菌斑检查以及软组织评估。使用两种牙刷30天后，菌斑和牙龈炎评分均较基线显著降低。然而，使用高露洁Actibrush的组在龈上菌斑和牙龈炎评分方面的改善明显更大。总之，虽然两种牙刷作为正常口腔卫生方案的一部分使用时都能显著改善菌斑和牙龈炎，但使用30天后，高露洁Actibrush的疗效被证明优于高露洁倍加牙刷。
