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

Phase 1

Completed

• Conditions: Biofilm Removal; Gingival Abrasion
• Interventions: Device: Two kind toothbrushes

• Registration Number: NCT01125007
• Lead Sponsor: Franciscan University Center

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).

Arm && Interventions

Group	Intervention	Description
toothbrush	Two kind toothbrushes	a randomization was performed in which the participants were allocated to the following experimental procedures: Two quadrants (1 and 3 or 2 and 4) with medium toothbrush Two quadrants with soft toothbrush. All procedures were performed using the same dentifrice. Each quadrant was brushed for 30 seconds by the participant without specific instructions on the technique, under supervision of the person in charge of the randomization.

Primary Outcome Measures

Name	Time	Method
Gingival abrasion	Presence of 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.
