The efficacy of an oscillating-rotating power toothbrush compared to a high-frequency sonic power toothbrush on parameters of dental plaque and gingival inflammation: A systematic review and meta-analysis.

ABSTRACT:

Aim

To establish the efficacy of oscillating-rotating power toothbrush (OR-PTB) compared to high-frequency sonic power toothbrush (HFS-PTB) on improving parameters of plaque and gingival inflammation. Safety and participants' preference were secondary interests.

Materials and methods

MEDLINE-PubMed and Cochrane-CENTRAL databases were searched, up to April 2021. Inclusion criteria were (randomized)controlled clinical trials that evaluated healthy humans brushing with an OR-PTB compared to a HFS-PTB. Evaluation for a minimum of 4 weeks, of one or more of the following parameters: plaque index scores (PI), bleeding scores (BS), number of bleeding sites (NoB) and gingival index scores (GI).

Results

Thirty two publications involving 38 comparisons were included after the independent screening. The descriptive analysis showed that in 54% of the comparisons, a significant difference in favour of the OR-PTB was found for PI, BS and GI scores. The Quigley and Hein index showed a significant difference of means (DiffM) between the end scores (DiffM 0.13, 95% CI [0.05;0.21] p < 0.001), as well as for the Rustogi-modified Navy index (DiffM 0.01, 95% CI [0.01;0.03] p = 0.002). This is in line with the meta-analysis for BS (DiffM 0.09, 95% CI [0.03;0.14] p = 0.003), for which the results were in favour of the OR-PTB and considered potentially clinically relevant. NoB showed a significant difference in favour of the OR-PTB for the end scores (DiffM 3.61, 95% CI [2.63;4.58] p < 0.00001). No difference in safety was indicated, 78% of participants preferred the OR-PTB.

Conclusion

For patients to maintain good plaque control and improve gingival health, there is a small but significant difference based on longer-term studies between OR-PTB and HFS-PTB. This difference is potentially clinically relevant.

Project description:ObjectivesThis exploratory study investigated plaque removal with a prototype constant, low rotation speed Power Toothbrush (PTB) with two brushing actions: "Gumline" (head rotates in the horizontal axis) and "Interdental" (head rotates in the vertical axis). Gumline alone and "Combined" (Gumline + Interdental) modes were compared with a Reference PTB and a Reference Manual Toothbrush (MTB) after one brushing.Materials and methodsThirty-nine participants were randomized to use each toothbrush once either in the sequence (A) Prototype PTB (in Gumline then Combined mode), (B) reference MTB, and (C) reference PTB or the sequence BAC. There was a minimum 3-day washout between the use of each toothbrush. Plaque removal was measured using the Rustogi Modified Navy Dental Plaque Index (RMNPI) with change from baseline investigated using an analysis of covariance model. RMNPI scores were calculated on a "whole mouth" basis and along the gingival margin and at proximal sites only.ResultsFor the primary efficacy variable, a significant difference was found in favor of the prototype PTB in gumline mode versus the reference MTB for whole mouth plaque score (difference: -0.06; standard error: 0.014; 95% confidence interval [CI] -0.09 to -0.04; p < .0001). Similar significant differences were found in gingival margin and proximal areas (p < .0001). The prototype PTB in gumline mode removed significantly less plaque than the prototype PTB in combined mode and the reference PTB (p < .0001; whole mouth/gingival/proximal areas). The prototype PTB in combined mode removed significantly more plaque than the reference MTB (p < .0001; whole mouth/gingival/proximal areas) and the reference PTB for whole mouth (p = .0214) and gingival margin areas (p = .0010). The reference PTB also removed significantly more plaque than the reference MTB (p < .0001; whole mouth/gingival/proximal areas). All brushes were generally well-tolerated.ConclusionThe prototype PTB design, providing two distinct cleaning modalities, can effectively remove plaque to a significantly higher degree than an MTB and a marketed PTB, depending on mode.

Project description:Clinical studies on the efficacy of sonic toothbrushes show inconsistent results, most studies have been conducted without sufficient supervision of appropriate toothbrush usage. Aims of the explorative clinical trial were therefore to investigate whether the usage of an activated sonic toothbrush reduces plaque more effectively than an inactivated one used as a manual toothbrush, and to which extent the correct use of such toothbrush plays a role in its efficacy. The clinical trial was designed as a video-controlled interventional study. Thirty participants (mean (±SD) age 22.9 (±2.5) years) were included, areas of interest were the buccal surfaces of the upper premolars and the first molar (partial mouth recording). Toothbrushing was performed without toothpaste in a single brushing exercise under four different conditions: switched off, habitually used as manual toothbrush, no instruction; switched on, habitually used as powered toothbrush, no instruction; switched off, used as manual toothbrush, instruction in the Modified Bass Technique; switched on, used as powered toothbrush, instruction in a specific technique for sonic toothbrushes. Brushing performance was controlled by videotaping, plaque was assessed at baseline (after 4 days without toothbrushing) using the Rustogi modified Navy-Plaque-Index and planimetry. Main study results were that plaque decreased distinctly after habitual brushing regardless of using the sonic brush in ON or OFF mode (p for all comparisons < 0.001). After instruction, participants were able to use the sonic brush in ON mode as intended, with only minor impact on efficacy. Using the toothbrush in OFF mode with the Modified Bass Technique was significantly less effective than all other conditions (p for all comparisons < 0.001). Under the conditions used, the sonic toothbrush was not more effective when switched on than when switched off, and there was no evidence that the correct use of the toothbrush was more effective than the habitual use.

Project description:BackgroundPatients with fixed orthodontic appliances have higher plaque accumulation and gingival inflammation. Our aim was to compare the effectiveness of a light emitting diode (LED) toothbrush with a manual toothbrush in reducing dental plaque and gingival inflammation in orthodontic patients with fixed appliances, and to investigate the effect of the LED toothbrush on Streptococcus mutans (S. mutans) biofilm in vitro.MethodsTwenty-four orthodontic patients were recruited and randomly assigned into 2 groups: (1) started with manual and (2) started with LED toothbrushes. After a 28-day usage and 28-day wash-out period, the patients switched to the other intervention. The plaque and gingival indices were determined at baseline and 28 days after each intervention. The patients' compliance and satisfaction scores were collected using questionnaires. For the in vitro experiments, S. mutans biofilm was divided into 5 groups (n = 6) with 15-, 30-, 60-, or 120-sec LED exposure, and without LED exposure as a control group.ResultsThere was no significant difference in the gingival index between the manual and LED toothbrush groups. The manual toothbrush was significantly more effective in reducing the plaque index in the proximal area on the bracket side (P = 0.031). However, no significant difference was found between the two groups in other areas around the brackets or on the non-bracket side. After LED exposure in vitro, the percentages of bacterial viability after LED exposure for 15-120 s were significantly lower compared with the control (P = 0.006).ConclusionClinically, the LED toothbrush was not more effective in reducing dental plaque or gingival inflammation than the manual toothbrush in orthodontic patients with fixed appliances. However, the blue light from the LED toothbrush significantly reduced the number of S. mutans in biofilm when it was exposed to the light for at least 15 s in vitro.Clinical trial registrationThai Clinical Trials Registry (TCTR20210510004).
