At-home bleaching versus whitening toothpastes for treatment of tooth discoloration: a cost-effectiveness analysis.

Objectives: This study aimed to analyze the cost-effectiveness of whitening toothpastes and at-home bleaching for the treatment of tooth discoloration.

Methodology: A cost-effectiveness economic analysis was conducted, and eight randomized clinical trials were selected based on the whitening agent product used: blue covarine dentifrices (BCD), hydrogen peroxide dentifrices (HPD), dentifrices without bleaching agents (CD, negative control), and 10% carbamide peroxide (CP10, positive control) for at-home bleaching. The consumer/patient perspective was adopted, macro-costing techniques were used and a decision tree model was performed considering the costs in the American and Brazilian markets.

Evaluation of Single-Shade Composite Resin Color Matching on Extracted Human Teeth.

Introduction: Universal single-shade composite resins are characterized by a property that enables the creation of restorations that mimic tooth structure to the extent possible with fewer shades of color.

Objectives: This study aimed to instrumentally and visually evaluate the color correspondence of two single-shade composite resins in extracted human teeth multishade composite resins.

Methods: Upper central incisors and upper and/or lower molars with intact buccal surfaces were selected.

Topical application of Otosporin® before in-office bleaching: a split mouth, triple-blind, multicenter randomized clinical trial.

Objectives: To evaluate if the topical application of Otosporin® before in-office bleaching with a 35% hydrogen peroxide (HP) gel reduces the risk and intensity of tooth sensitivity (TS), as well as the bleaching effectiveness.

Materials And Methods: Twenty participants were selected for this split mouth, triple-blind, multicenter randomized clinical trial. Before each bleaching session, the placebo was applied in the patient's hemi-arch and the other half received the Otosporin®, according to the randomization procedure.

Effects of a reduced in-office bleaching protocol with 37.5% hydrogen peroxide on effectiveness and tooth sensitivity: A double-blind randomized clinical trial.

Objective: This randomized clinical trial evaluated the effectiveness and tooth sensitivity (TS) of 37.5% hydrogen peroxide (37.5HP) in-office bleaching with reduced protocol.
