This half-mouth design, two-week treatment phase, combined with an 11-week evaluation double-blinded randomized clinical trial was conducted to compare two in-office bleaching products, StarBrite (35% hydrogen peroxide) with Opalescence Xtra Boost (38% hydrogen peroxide), for degree of color change of teeth, any relapse effect (darkening) associated with discontinued use and gingival irritation...

OBJECTIVE To use the criteria set by the American Dental Association to evaluate the effectiveness of nightguard vital bleaching with 10% carbamide peroxide through a controlled randomized clinical trial. MATERIALS AND METHODS Fifty volunteers allocated to either an experimental group(Opalescence PF 10%; OPA) or a control group (placebo; PLA) used a gel for 21 days. Observations of tooth colo...

INTRODUCTION A number of vital pulp therapy techniques have been recommended to preserve pulp vitality in teeth with complicated crown fractures, especially in young patients. Calcium hydroxide has been the gold standard as a pulp capping material, but recently mineral trioxide aggregate (MTA) has been recommended.
