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

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).

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

The study was conducted on 25 participants selected among undergraduate dental students of UNIFRA (Santa Maria, Rio Grande do Sul, Brazil)
Males and Females
All systemically healthy
Aged 18 to 30 years (mean age 21.4 ± 3.9 years) with at least 20 present teeth

Exclusion criteria

The exclusion criteria comprised presence of sites with attachment loss ≥ 2mm
Orthodontic appliances
Prostheses
Dental implants
Aabrasions, restorations and/or carious lesions on the cervical region

Treatment and study plan

Two kind toothbrushes

Device

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 outcomes

Gingival abrasion

Time frame: 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.
