The goal of this multicenter randomized controlled study was to evaluate the effectiveness of a newly developed ionic-sonic electric toothbrush in terms of plaque removal and reduction of gingival inflammation. A total of 78 subjects from three dental centers were invited to join the study. They were randomized to receive either a manual toothbrush (control group) or an ionic-sonic electric brush (test group). Full-mouth prophylaxis and oral hygiene instructions based on the stationary bristle technique were provided 1 week prior to the baseline visit. At baseline and at each follow-up appointment, Plaque Index (PI) and Gingival Index (GI) were recorded. In addition, probing depth (PD) and bleeding on probing were recorded at baseline and at the last appointment (week 5). At completion of the study, subjects in the test group were given a questionnaire regarding their satisfaction with the toothbrush. Sixty-four subjects completed the study (control: 28; test: 36). The mean age of the subjects was 36.90 ± 12.19 years. No significant difference between the baseline and 5-week PD was found. Plaque removal efficacy and reduction in gingival inflammation were more significant for the test group at week 2. Both the control and test groups showed statistically significant improvement in PI and GI from baseline to week 5. The ionic-sonic toothbrush was more effective than manual toothbrush after a 1-week application.
本多中心随机对照研究的目的是评估一种新型离子声波电动牙刷在去除牙菌斑和减少牙龈炎症方面的有效性。从三个牙科中心邀请了 78 名受试者参加这项研究。他们被随机分配使用手动牙刷（对照组）或离子声波电动牙刷（试验组）。在基线访问前 1 周，进行全口预防和基于静止刷毛技术的口腔卫生指导。在基线和每次随访时，记录菌斑指数（PI）和牙龈指数（GI）。此外，在基线和最后一次就诊（第 5 周）时记录探诊深度（PD）和探诊出血。研究完成时，试验组的受试者被要求就他们对牙刷的满意度回答一份问卷。64 名受试者完成了研究（对照组：28 名；试验组：36 名）。受试者的平均年龄为 36.90±12.19 岁。在第 5 周时，PD 与基线相比无显著差异。在第 2 周时，试验组的牙菌斑去除效果和牙龈炎症减轻更为显著。对照组和试验组的 PI 和 GI 均从基线到第 5 周显著改善。离子声波牙刷在应用 1 周后比手动牙刷更有效。
