The aim of this randomized clinical trial was to assess the efficacy of an oscillating-rotating toothbrush in reducing plaque and inflammation around dental implants.
Eighty patients presenting dental implants were enrolled in this study and assigned randomly to two different groups: 40 patients in the test group and 40 in the control one. Each patient in the test group received an oscillating-rotating toothbrush while in the control group patients kept using the manual toothbrush. Furthermore, the test group received a special toothbrush head designed for dental implants and another one for natural teeth. Domiciliary oral hygiene instructions were given to both groups. Periodontal parameters like plaque index (PI), bleeding on probing (BoP), and probing pocket depth (PPD) were recorded at the baseline and after 1 and 3 months.
At the end of the study, the difference of plaque and bleeding indices with the baseline was statistically significant for both test and control groups (P < 0.0001). Implant sites showed higher values of both BoP and PI when compared to the natural teeth. In the second part of the study, comparing the 1-3-month period, the oscillating-rotating toothbrush was effective in reducing new plaque formation (P < 0.0001) and bleeding (P < 0.0001) both at the implant sites and the dental sites comparing to manual ones (P > 0.05). No significant differences were appreciated concerning the PPD.
The oscillating-rotating toothbrush can be successfully used for the plaque and bleeding control of the peri-implant tissues.
这项随机临床试验的目的是评估一款振动旋转式牙刷在减少牙种植体周围牙菌斑和炎症方面的效果。
80名有牙种植体的患者参与了本研究，并被随机分为两组：试验组40名患者，对照组40名患者。试验组的每位患者都收到了一支振动旋转式牙刷，而对照组的患者继续使用手动牙刷。此外，试验组还收到了专门为牙种植体设计的牙刷头和另一个用于天然牙的刷头。两组都接受了家庭口腔卫生指导。在基线以及1个月和3个月后记录牙周参数，如菌斑指数（PI）、探诊出血（BoP）和探诊袋深度（PPD）。
在研究结束时，试验组和对照组的菌斑和出血指数与基线相比差异具有统计学意义（P < 0.0001）。与天然牙相比，种植体部位的BoP和PI值更高。在研究的第二部分，比较1至3个月期间，与手动牙刷相比，振动旋转式牙刷在减少种植体部位和牙齿部位新的菌斑形成（P < 0.0001）和出血（P < 0.0001）方面有效（P > 0.05）。在PPD方面未观察到显著差异。
振动旋转式牙刷可成功用于控制种植体周围组织的菌斑和出血。
