Impact of bracket displacement or rotation during bonding and time of removal of excess adhesive on the bracket-enamel bond strength.

Objective: This study investigated the the influence of bracket displacement or rotation during fixation and the time of excess adhesive removal from around the bracket on bond strength to enamel.

Methods: Stainless steel brackets were bonded to the buccal faces of bovine incisors using Transbond XT® adhesive resin. The teeth were divided into five groups (n = 20).

Effect of triazine derivative added to denture materials on a microcosm biofilm model.

The aim of this study was to assess the effect of triazine incorporation to denture materials on biofilm formation of saliva derived from microcosms of patients who are positive for Candida albicans. Biofilms were formed on microwave-cured acrylic resin, one hard denture liner, and two soft denture liners containing 0, 2.5, 5, and 10% triazine.
