Última Carbamide peroxide gel stability under different temperature conditions: is manipulated formulation an option? BJPS Bonesi,Camila de Martini; Ulian,Letícia Storchi; Balem,Paula; Angeli,Valeria Weiss. Nowadays the use of gel containing carbamide peroxide (CP) prepared in Pharmacy is a normal practice in the population. However, the quality of this product is questionable concerning its stability. The aim of this study is was to synthesize and to analyze this drug alone or associated to Carbopol gel through analytical methodology compatible with the routine of the Pharmacies. The reaction between urea and hydrogen peroxide was carried out at different resting times: 24 hours (CP 24 powder) and 48 hours (CP48 powder) after the mixture. Both products were associated with Carbopol 940® gel 1.5% (G) generating G24 and G48 samples. The stability of powders (CP24 e CP48) and the formulations (G24 and G48) were evaluated as a function of time (15, 40 and 45...

The aim of this study was to evaluate the effects of external bleaching agents on morphology of human enamel after excessive homemade dental bleaching. 20 intact human third molars were submitted to mesio-distal crosscut and embedded in polystyrene resin. The specimens were submitted to finish and a half of enamel surface of each specimen was covered with cosmetic varnish, meaning control group (G0). The specimens were randomly divided into four groups (n=10): G1 ­ 1 bleaching session by 16% carbamide peroxide; G2 ­ 3 bleaching sessions by 16% carbamide peroxide; G3 ­ 1 bleaching session by 22% carbamide peroxide; G4 ­ 3 bleaching sessions by 22% carbamide peroxide. Each session lasted 8 hours a day, during two weeks, with 45 days of interval between... Tipo: Journal article Palavras-chave: Dental bleaching; Dental enamel; Peroxides.
