Summary

This study compared Guided Biofilm Therapy with conventional polishing in adults with visible extrinsic tooth staining. Each participant received Guided Biofilm Therapy on one side of the mouth and conventional polishing on the other side.

The study evaluated whether the two methods differed in the amount of tooth re-staining after treatment, patient discomfort during the procedures, and total procedure time. Tooth color was measured with a spectrophotometer immediately after treatment, at 1 month, and at 2 months. Patient discomfort was recorded using a visual analog scale, and procedure time was measured with a stopwatch.

A total of 34 participants completed the study.

Conditions

  • Tooth Stain

Interventions

PROCEDURE

Guided Biofilm Therapy

Dental biofilm was first disclosed to guide treatment. Supragingival biofilm and extrinsic staining were then removed using an air-water-powder system with a low-abrasive erythritol-based powder. Supragingival ultrasonic instrumentation was performed where necessary, followed by final surface control.

PROCEDURE

Conventional Polishing

Supragingival instrumentation was performed as needed, followed by mechanical polishing with a prophylaxis brush and polishing paste at 2500 to 3000 rpm. The procedure was completed with final surface control.
