Evaluation of bond strength of orthodontic brackets without enamel etching
BACKGROUND To compare the shear bond strength of brackets with and without enamel etching. MATERIAL AND METHODS In this study, 60 sound premolars were randomly divided into four different groups: 1- TXE group: Enamel etching+Transbond XT adhesive+ Transbond XT composite. 2- TXS group: Transbond plus self-etch adhesive+ Transbond XT composite. 3- PQ1E group: Enamel etching+ PQ1 adhesive+ Trans...
متن کاملThe effect of different surface treatments of demineralised enamel on microleakage under metal orthodontic brackets
BACKGROUND The aim of this investigation was to assess the effects of different treatments of demineralised enamel on microleakage under orthodontic brackets. METHODS Seventy-five intact premolars were randomly assigned to five groups. The teeth in groups 2 through 5 were immersed in a demineralising solution for 16 weeks. In groups 1 (control) and 2 (demineralised/control), conventional acid...
متن کاملEfficacy of Enamel Remineralizing Agents in Prevention of Dental Caries Around and Beneath Orthodontic Brackets
Background and purpose: Enamel demineralization around orthodontic brackets is a significant problem. This study aimed to compare the efficacy of Casein phosphopeptide amorphous calcium phosphate (CPP-ACP) varnish and fluoride varnish in preventing enamel demineralization around and beneath orthodontic brackets. Materials and methods: Twenty extracted premolars were randomly divided into two g...
متن کاملEffect of adhesive resin flexibility on enamel fracture during metal bracket debonding: an ex vivo study.
OBJECTIVE To test the null hypothesis that neither the flexural properties of orthodontic adhesive resins nor the enamel pre-treatment methods would affect metal bracket debonding behaviours, including enamel fracture. MATERIALS AND METHODS A dimethacrylate-based resin (Transbond XT, TX) and two methyl methacrylate (MMA)-based resins (Super-Bond C&B, SB; an experimental light-cured resin, EXP...
متن کاملبررسی آزمایشگاهی میزان ریزنشت براکت‌های ارتودنسی باند‌شده با کامپوزیت بیس متاکریلات و کامپوزیت بیس سایلوران
Background: One of the orthodontic treatment problems, which causes marginal gaps and microleakage between tooth and composite is microleakage of composite bonding of orthodontic brackets. The microleakage formation permitting the passage of bacteria and oral fluids, which may cause white spot lesions under the brackets surface area.This is a clinical problem during orthodontic treatment. Few s...
