Tapered toothbrush filaments in relation to gingival abrasion, removal of plaque and treatment of gingivitis.

Objectives: To compare a tapered filament toothbrush (TFTB) to a control toothbrush (ADA) in their potential to cause gingival abrasion and improve the gingival condition following a period of experimental gingivitis.

Methods: Thirty-two subjects refrained from brushing mandibular teeth for 21 days. During a subsequent 4-week treatment phase, the left or right side of the mouth was brushed with either the TFTB or ADA as randomly allocated.

[Tooth brushing and gingival abrasion].

It has been known for some time that tooth brushing can have unwanted effects on the gingiva and hard dental tissues. The aim of this study is to evaluate two factors that may be of influence on the incidence of gingival abrasion during tooth brushing. The first factor being the possible influence of feedback through oral sensory perception and the second the possible abrasive effects of dentifrice.

An oscillating/pulsating electric toothbrush versus a high-frequency electric toothbrush in the treatment of gingivitis.

Objectives: The objective of this study was to compare the effect of an oscillating/pulsating power toothbrush (Oral-B ProfessionalCare 7000; PC 7000) and a high-frequency power toothbrush (Philips Sonicare Elite; SE) on the reversal of experimental gingivitis.

Methods: The study had a randomised, examiner-blind, split-mouth design. After dental prophylaxis, subjects refrained from brushing mandibular teeth for 21 days to allow development of gingivitis.

Approximal brush head used on a powered toothbrush.

Aim: This study was designed to test whether the approximal efficacy of a powered toothbrush (Braun Oral-B 3D Plaque Remover) can be improved when a pointed-shaped brush head (PBH) specifically designed for these approximal areas is used as compared with the standard cup-shaped brush head (CBH).

Material And Methods: Forty non-dental students were included. They all received the powered toothbrush and two different brush heads (CBH+PBH).

Brushing with and without dentifrice on gingival abrasion.

Objectives: This study was designed to evaluate two factors possibly influencing incidence of gingival abrasion during toothbrushing: (1) the abrasiveness of a dentifrice and (2) the possible influence of feedback of oral sensory perception.

Material And Methods: For this purpose, two separate, single blind, randomized clinical experiments were performed. The two groups of subjects were requested not to brush their teeth 48 h, prior to the experiments.
