Evaluation of the isosceles-configured SUN teeth^tm toothbrush in dental plaque removal and gingival health

Objective: To evaluate the clinical efficacy and safety profile of a novel-designed isosceles-configured (SUN Teeth™) toothbrush in comparison to a standard reference toothbrush with end-rounded bristles (approved by the American Dental Association [ADA]). Methods: The sample size was determined using the G-Power-software, version 3.1.2 and, accordingly, 104 subjects (ages 19 years to 25 years) were recruited and randomized into either the test group (n = 54) or the control group (n = 50). Prior to study commencement, scaling was performed followed by abstinence from oral hygiene for 24 hours. Baseline pre-brushing gingivitis scores (Lobene) and plaque scores (Turesky modification of Quigley Hein) were recorded. Brushing was performed for 3 minutes and post-brushing scores were recorded on days 1, 14, and 28 without refraining from regular brushing. Data were analysed with Statistical Package for Social Sciences (IBM-SPSS, v.25.0). Results: Post-brushing plaque scores showed significant reduction in both groups at all time intervals. However, no significant differences between the test and control brush groups were achieved at any time points. Conclusion: The isosceles-configured SUN Teeth™ toothbrush is equivalent in plaque removal to the conventional flat-bristled ADA reference brush.
