A Randomized Clinical Study of the Plaque Removal Efficacy of a Novel Manual Toothbrush With Micro-Pulse Bristles on Fixed Orthodontic Patients.

Background Fixed orthodontic appliances on tooth surfaces, such as brackets and bands, complicate oral hygiene and increase plaque accumulation, contributing to gingivitis, periodontitis, and tooth decay. While manual toothbrushes are an essential part of oral hygiene, there is little clinical evidence to demonstrate how effective manual toothbrushes with novel designs are at removing plaque from orthodontic patients. This study aims to evaluate three types of manual toothbrushes (Pulsar, conventional flat trim (C-TB), and orthodontic type (O-TB)) for their efficacy in plaque removal among patients undergoing fixed orthodontic treatment. Methodology The study followed the Consolidated Standards of Reporting Trials (CONSORT) guidelines. It was a three-treatment, three-period, examiner-blinded crossover clinical trial conducted with a single brushing exercise. Twenty-four subjects were randomized to one of three different bristle designs (Pulsar, C-TB, and O-TB). The primary outcome measure was the difference (baseline minus post-brushing) in plaque scores assessed using the Turesky-Modified Quigley-Hein Plaque Index during each study period. Results Of the 27 subjects enrolled in the study, 24 met the inclusion criteria and completed all three periods of the study. The mean age was 19.58 ± 1.55 years, with a range of 18-23 years. The differences between treatments in plaque score reduction after brushing were statistically significant (p-value <0.001). The treatment differences were statistically significant (p-value <0.001), favoring the C-TB toothbrush and the O-TB over the Pulsar design. On the contrary, the difference between the O-TB and C-TB types was not statistically significant. Conclusions C-TB and O-TB remove significantly more plaque than Pulsar toothbrushes after a single brushing exercise. Nevertheless, the C-TB tested in this study was more effective in removing dental plaque than the O-TB in patients wearing fixed orthodontic appliances. Considering the limitations of this study, additional research is required before evidence-based advice concerning the relative performance of the Pulsar toothbrushes in fixed orthodontic patients can be proven.
