The aim of this 12-month parallel design controlled clinical trial was to assess the effect of the Braun Oral-B Plak Control electric toothbrush on supragingival plaque and gingival health, and to compare it with a conventional soft manual toothbrush (Jordan). A total of 111 patients aged between 20 and 63 years, from a general population, with bleeding on probing at 30% or more of all sites examined were entered into the study. At baseline, immediately after periodontal examination, all volunteers received a thorough scaling of their teeth. Volunteers in both groups were told to brush their teeth for 2 min 2 x a day. Oral hygiene instruction was given at the start of the study and was not repeated. At 3, 6 and 12 months, assessments were carried out by a single clinician who was not aware which group the volunteers belonged to. Analysis of results demonstrated that over the 12 months of the study, the Braun Oral-B Plak Control was significantly more effective in improving gingival health than the manual toothbrush. There was, however, no difference between the 2 groups in terms of plaque removal, with the number of sites with visible plaque decreasing by a similar amount in both groups. In conclusion, results indicate that the Braun Oral-B Plak Control toothbrush is safe and more effective than a manual toothbrush in improving gingival health.
这项为期12个月的平行设计对照临床试验的目的是评估博朗欧乐-B防菌斑电动牙刷对龈上菌斑和牙龈健康的影响，并将其与传统软毛手动牙刷（乔丹）进行比较。共有111名年龄在20至63岁之间、来自普通人群、在所有检查部位中有30%或更多部位探诊出血的患者进入该研究。在基线时，即牙周检查后立即对所有志愿者的牙齿进行彻底洁治。两组志愿者均被告知每天刷牙2次，每次2分钟。在研究开始时给予口腔卫生指导，且不再重复。在3个月、6个月和12个月时，由一名不了解志愿者所属组别的单一临床医生进行评估。结果分析表明，在研究的12个月中，博朗欧乐-B防菌斑电动牙刷在改善牙龈健康方面比手动牙刷显著更有效。然而，两组在菌斑清除方面没有差异，两组中可见菌斑部位的数量减少量相似。总之，结果表明博朗欧乐-B防菌斑牙刷在改善牙龈健康方面比手动牙刷更安全、更有效。
