The use of a toothbrush with radio frequency (RF) has shown to be of benefit regarding the reduction of plaque, calculus, and dental staining and improving teeth shade compared to conventional powered and manual toothbrushes.
To evaluate the efficacy of the RF toothbrush in the reduction of calculus accumulation and its effect on periodontal parameters as well as subject satisfaction as compared to an identical sham-tooth brush.
Patients who are under a strict maintenance program were included. Patients were allocated to test (RF toothbrush) or control (sham) randomly and were examined at baseline, one and three months. Clinical photos were taken and a consequential calculus assessment via ImageJ software. Clinical assessment included the following: plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and recession (REC). Patient satisfaction was assessed via a questionnaire.
Fifty-eight patients (29 control, 29 test) were included. At baseline mean PPD, BOP, PI, REC, and calculus accumulation were similar between the groups. Mean buccal calculus was lower in the test group at one month 4.0% versus 6.7%, p < .05. Calculus accumulation within the groups was lower in the test group at 1 and 3 months when compared to baseline at the buccal aspect (2.8% vs. 8.9%, p < .05% and 3.8% vs. 8.9%, p < .05) and lingual aspect (6.7% vs. 16.5%, p < .05% and 8.9% vs. 16.5%, p < .05). No statistically significant results were found regarding periodontal parameters PPD, BOP, PI, and REC. No difference was found between groups regarding patient satisfaction.
RF seems to have an additive effect on preventing calculus accumulation on the buccal aspect of anterior mandibular teeth at 1 month. Nevertheless, at 3 months, no difference between the toothbrushes is seen regarding calculus formation and maintaining periodontal health (ClinicalTrials.gov, Identifier NCT04640857).
与传统的动力牙刷和手动牙刷相比，使用带有射频（RF）的牙刷在减少牙菌斑、牙石和牙齿着色以及改善牙齿色泽方面显示出有益的效果。
评估 RF 牙刷在减少牙石堆积方面的功效，以及与相同的假牙刷相比对牙周参数和患者满意度的影响。
纳入了正在接受严格维护方案的患者。患者随机分配到试验（RF 牙刷）或对照组（假牙刷），并在基线、一个月和三个月时进行检查。拍摄临床照片，并使用 ImageJ 软件进行随后的牙石评估。临床评估包括以下内容：菌斑指数（PI）、探诊出血（BOP）、探诊牙周袋深度（PPD）和牙龈退缩（REC）。通过问卷评估患者满意度。
共纳入 58 名患者（对照组 29 名，试验组 29 名）。在基线时，两组的平均 PPD、BOP、PI、REC 和牙石堆积相似。在一个月时，试验组的颊侧平均牙石较少，为 4.0%，而对照组为 6.7%，p<0.05。与基线相比，试验组在 1 个月和 3 个月时在颊侧和舌侧的牙石堆积均较低（2.8%比 8.9%，p<0.05%和 3.8%比 8.9%，p<0.05）和舌侧（6.7%比 16.5%，p<0.05%和 8.9%比 16.5%，p<0.05）。在 PPD、BOP、PI 和 REC 等牙周参数方面，未发现统计学上的显著差异。两组患者的满意度无差异。
RF 在 1 个月时似乎对预防前下颌牙齿颊侧的牙石堆积有附加效果。然而，在 3 个月时，两种牙刷在牙石形成和维持牙周健康方面没有差异（ClinicalTrials.gov，标识符 NCT04640857）。
