Model Based vs. Screen-Based Instruction: Improving Plaque Removal with Powered and Manual Toothbrushes in Children
Abstract
Purpose: This study aimed to comparatively evaluate the effectiveness of powered and manual toothbrushes in plaque removal. In addition, it sought to determine which of two oral hygiene training techniques, model-based instruction or video demonstration, produced greater improvements in brushing efficiency. Materials and Methods: Forty pediatric patients aged 8–12 years were included. Twenty children received training with powered toothbrushes and twenty with manual toothbrushes. Each group was further divided into two subgroups: one received brushing instruction via video, and the other received model-based instruction. Plaque index measurements were performed using the Silness & Löe Plaque Index at baseline (day 0), day 15, and day 30. The level of statistical significance was set at p<0.05. Results: Forty children (mean age 9.48 years) were randomized and completed the study. Statistical analysis revealed that median plaque scores in the powered toothbrush group were significantly lower than those in the manual toothbrush group. Moreover, the subgroup using powered toothbrushes combined with model-based instruction demonstrated the greatest reduction in plaque levels. Conclusions: Pediatric dentists may recommend powered toothbrushes to their patients, given their superior efficacy in plaque removal. Furthermore, model-based oral hygiene education appears more motivating and effective than video-based instruction, particularly when delivered face-to-face.
