To compare the extrinsic stain-removing properties and the safety of the Braun Oral-B 3D Plaque Remover and the Sonicare Plus electric toothbrush.
This randomized, parallel group, investigator-blinded study involved 67 subjects and was conducted over 6 weeks. After recruitment, the subjects received a baseline stain assessment (Lobene stain index) and a soft and hard tissue examination, and were then randomized to use either the Sonicare or the 3D device. All subjects were trained to use both devices, and instructed to brush twice daily with their assigned device for 2 min. The subjects' brushing technique was checked after 2 weeks. After a further 4 weeks, the subjects underwent a final stain assessment and soft and hard tissue examination. A questionnaire was also completed.
At 6 weeks, oral hard and soft tissue examinations revealed no abrasion or damage in either group. Both brushes produced significant (P < 0.001) reductions from baseline in total stain score, stain area and intensity, but group comparisons showed that these reductions were significantly (P < 0.001) greater for the 3D device.
比较博朗欧乐-B 3D洁牙器和飞利浦声波震动牙刷的外在污渍清除性能及安全性。
本随机、平行组、研究者盲法研究共纳入67名受试者,为期6周。招募后,受试者接受基线污渍评估(洛贝内污渍指数)及软组织和硬组织检查,随后随机分为使用声波震动牙刷组或3D洁牙器组。所有受试者均接受两种器械的使用培训,并被要求使用指定器械每天刷牙两次,每次2分钟。2周后检查受试者的刷牙技巧。再过4周后,受试者接受最终污渍评估及软组织和硬组织检查。同时完成一份问卷。
6周时,口腔软硬组织检查显示两组均无磨损或损伤。两种牙刷在总污渍评分、污渍面积和强度方面均较基线有显著降低(P < 0.001),但组间比较显示,3D洁牙器的这些降低更为显著(P < 0.001)。
