The effect of visual feedback and self-scaling on plaque control behavior

Area of Science:

• Periodontology
• Behavioral Science
• Biomedical Engineering

Background:

• Psychological factors influence patient adherence to oral hygiene practices for periodontal health.
• Visual feedback and patient self-intervention are potential strategies to modify oral hygiene behavior.

Purpose of the Study:

• To assess the modification of plaque control behavior in patients using a specially-designed optical system and performing self-scaling.
• To compare the effectiveness of patient self-scaling with professional scaling in improving oral hygiene.

Main Methods:

• A pilot study involving twelve patients divided into an experimental group (optical devices, self-scaling) and a control group (professional scaling).
• Both groups received 3 hours of chairside education and intervention.
• Plaque control was assessed using the PHP index before and five months after treatment.

Main Results:

• The experimental group showed a significant reduction in the mean PHP index from 3.2 to 0.7.
• The control group's mean PHP index decreased from 3.2 to 1.9.
• Patients performing self-scaling effectively removed supragingival calculus and extrinsic stains, comparable to a trained hygienist.

Conclusions:

• Specially-designed optical devices combined with self-scaling can significantly improve plaque control behavior and periodontal health.
• Patient self-intervention, supported by visual feedback, offers an effective alternative for supragingival calculus and stain removal.
• This approach holds promise for enhancing patient engagement in maintaining oral hygiene.
