The Effect of Visual Feedback on Plaque Control: An RCT Comparing Toothbrushing Methods in Periodontitis Patients.

Area of Science:

• Periodontology
• Preventive Dentistry
• Oral Hygiene Research

Background:

• Gingivitis prevalence correlates with plaque accumulation, necessitating effective oral hygiene for healthy gingival tissues.
• Maintaining periodontal health is essential following initial periodontal treatment.
• Understanding the impact of different toothbrushing methods on plaque and periodontal health is critical.

Purpose of the Study:

• To evaluate the impact of manual toothbrushing (MTB), electric toothbrushing (ETB), and electric toothbrushing with visual feedback (ETBV) on plaque levels and periodontal health.
• To compare the efficacy of different toothbrushing modalities in patients post-periodontal treatment.
• To assess changes in probing depth and bleeding on probing (BoP) over a 12-week period.

Main Methods:

• Sixty patients were randomized into three groups: MTB, ETB, and ETBV.
• Clinical parameters including plaque levels and bleeding on probing (BoP) were assessed at baseline and over 12 weeks.
• Statistical analysis using linear mixed models was employed to determine group effects and changes over time.

Main Results:

• All groups showed significant reductions in plaque levels (p < 0.001).
• Significant improvements in bleeding on probing (BoP) were observed across all groups (p < 0.001).
• No significant difference in plaque removal efficacy was found between manual and electric toothbrushes, with or without visual feedback (p > 0.190).

Conclusions:

• Consistent oral hygiene practices are vital for reducing periodontal disease.
• While all tested toothbrushing methods improve oral health, electric toothbrushes did not demonstrate superior plaque removal compared to manual ones in this study.
• Further research is needed to enhance patient adherence and optimize oral health outcomes through effective strategies.
