Capacity of Biofilm Removal and Gingival Abrasion After Utilization Medium and Soft Toothbrushes

Study Overview
=================
Brief Summary
-----------------
This study compared the removal of dental biofilm between soft and medium toothbrushes. The patients refrained from performing mechanical or chemical plaque control for 96 hours to allow dental biofilm accumulation on the tooth surfaces. After the period of dental biofilm formation, the quadrants were randomized and the participants brushed different quadrants with soft and medium toothbrushes, with or without dentifrice. The plaque indices were analyzed by a blinded examiner before and after toothbrushing. The 2Tone was used for plaque disclosure and analysis was performed by the Quigley-Hein index modified by Turesky et al. (1970).

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Gingival abrasion | All gingival quadrants were analised by photographs made in different experimental times. After that, all photographs were evaluated in a blinded manner, according to the methodology suggested by Danser, et al. (1998), dividing the region to be analyzed in three areas: cervical, interdental and mid-gingival. In each area, the presence of gingival abrasion was assessed dichotomically. | Presence of gingival abrasion |
