Supragingival Plaque Removal With and Without Dentifrice
Supragingival Plaque Removal With and Without Dentifrice
Purpose: The aim of this study was to compare the efficacy of dental biofilm removal by
 brushing with and without conventional toothpaste. Settings and Design: Twenty-four students
 aged 17 to 28 years old participated in this randomized clinical trial.

 Materials and Methods: Quadrants 1-3 or 2-4 were randomly allocated to the test group
 (brushing without dentifrice) or control group (brushing with dentifrice). After 72 hours of
 cessation of oral hygiene, Quigley & Hein (Turesky) plaque index was assessed before and
 after brushing by a calibrated and blind examiner. Overtime and intergroup comparisons were
 performed by paired sample t test.
