We investigated the physical properties and tooth-whitening effect of polymeric compositions based on orally acceptable polymers, polyvinyl acetate (PVAc), ethyl cellulose (EC), pyrrolidone. The composition was prepared with hydrogen peroxide (H2O2) as a tooth-bleaching agent an polymer through simple mixing stirring in alcohol. PVAc EC polymers showed non-erosive features sustainable matrices ...

Background: Dental sensitivity is a common secondary effect related to vital tooth whitening (VTW) treatment and it’s associated with the concentrations time of application bleaching agents. The aim this research was evaluate relationship dental combinations different peroxides [hydrogen peroxide (HP) 10%/HP 40%] in order define protocol that effective, while minimizing discomfort experienced b...

The increase in aesthetic demands has increased the use of ceramic dental restorations dentistry. Ceramic are bonded to tooth structure using adhesives. There is a lack standard guidelines terms post-bleaching time intervals and bond strengths restorations. Bleaching products have also been stated affect morphology enamel. Therefore, purpose this systematic review evaluate strength between enam...

UNLABELLED To clinically evaluate the effectiveness of Nite White 10% carbamide peroxide with amorphous calcium phosphate, potassium nitrate and fluoride over a 6-month follow-up period. Nite White was applied nightly for 14 days, according to the manufacturer's instructions. The color of teeth 11 and 21 of twenty one subjects was measured with a spectrophotometer (L(*); a(*); b(*)). Subjects w...

Objective. To identify participants' satisfaction with appearance and the desired treatment to improve aesthetics. Materials and Methods. 220 participants (127 males and 93 females, mean age = 21.4 ± 1.5 years) were recruited into the study. A structured questionnaire was used to assess patients' satisfaction with appearance and what treatment they desire to improve aesthetics. Participants sco...

OBJECTIVE The purpose of this in vitro study was to compare the efficacy of a bleaching toothpaste containing Blue Covarine vs. conventional tooth bleaching techniques using peroxides (both in-office and at-home). MATERIAL AND METHODS Samples were randomly distributed into five experimental groups (n=15): C - Control; BC - Bleaching toothpaste containing Blue Covarine; WBC - Bleaching toothpa...
