Objectives: To compare the long-term in vitro effectiveness of a newer desensitizing agent containing bioactive glass and two other commercial products employed for dentin hypersensitivity. Methods: Fifty occlusal dentin disks from extracted sound human third molars were treated with 0.5M ethylenediaminetetraacetic acid for 2 min then randomly divided into five groups (n=10). Specimens were bru...

UNLABELLED Power toothbrushes (PTBs), in combination with abrasive dentifrices, may encourage wear of dental cements at crown margins. PURPOSE The objective of this in vitro simulation was to control the clinical variables associated with PTB use and measure the potential side effects of PTBs with mild and abrasive dentifrices. METHODS AND MATERIALS Four PTBs ( Braun-Oral-B-Professional Car...

ABSTRACT Objective: To evaluate the knowledge of orthodontic professionals regarding prescription dentifrices and antiseptics during treatment. Methods: An observational descriptive exploratory study national scope was conducted with 440 Brazilian orthodontists, based on previous sample calculations, to clinical practice orthodontists in prescribing antiseptics. Self-managed electronic question...
