The purpose of this in vitro study was to determine the effect of bleaching on shear bond strength of orthodontic brackets. This randomized control trial was performed over a period of 6 months in the department of orthodontics, de,Montmorency College of Dentistry, Lahore. A total of one hundred and forty extracted premolar teeth were included which were further divided into two groups. Group A...
BACKGROUND Tooth sensitivity (TS) is the most common side effect of dental bleaching therapies. Dexamethasone has been used with tooth bleaching to reduce TS. The efficacy of dexamethasone for this purpose has not been well studied. METHODS The authors conducted a triple-masked, randomized, clinical trial with a parallel design involving 63 healthy participants who received either a placebo o...
Tooth discoloration is commonly found in the dental clinic and tooth bleaching has been considered the preferred esthetic alternative, being more conservative, safe and with predictable results. Supervised home-use of 10% Carbamide Peroxide (CP) bleaching with custom-trays is the most common bleaching procedure dispensed by dentists to their patients. The good results obtained with this techniq...

background and aim(s): since it is possible for carbamide peroxide (cp) bleaching agent to contact with amalgam restorations in the oral cavity, the present in vitro study evaluated the amount of dissolved mercury released from amalgam restorations with various percentages of silver content subsequent to the use of 15% cp. materials and methods: thirty ana 2000 amalgam disks with 43.1% silver c...
conclusions the bleaching procedures using 20% carbamide peroxide and 45% carbamide peroxide and diode laser significantly decreased shear bond strength of brackets to the teeth. 45% carbamide peroxide had a more significant effect on bond strength compared to 20% carbamide peroxide. the difference in bond strength was not significant between laser group and either carbamide peroxide groups. re...
objectives: a reduction in bond strength of composite to bleached enamel has been reported immediately after bleaching treatment. application of some antioxidant agents may decrease the adverse effects of whitening agents on bond strength and enhance composite bond to enamel. this study aimed to assess the effect of green tea, sodium ascorbate, sage and grape seed extract on bond strength of co...
