Clinical evaluation of different types of teeth in in-office whitening.

Objective: This prospective case series aimed to clinically evaluate the bleaching effect, spontaneous tooth sensitivity, and variation in the thermal sensation threshold of different groups of teeth undergoing in-office bleaching.

Method And Materials: Ten patients received conventional bleaching treatment: 35% hydrogen peroxide with three bleaching sessions of 45 minutes, evaluating color change (∆E and ∆E00), Whitening Index (WID), and tooth sensitivity (visual analog scale). Thermal stimulus-generating devices were used to simulate sensitivity caused by low temperatures through quantitative sensory tests.

Efficacy of different in-office treatments for dentin hypersensitivity: randomized and parallel clinical trial.

The aim of this clinical, prospective, randomized, and parallel study was to evaluate different in-office treatments for dentin hypersensitivity (DH). One hundred ninety-two teeth with non-cavitated root exposures were treated using different desensitizers: fluoride varnish (Duraphat - FLU); bioactive ceramic solution (Biosilicate - BIOS); universal self-etching adhesive (Single Bond Universal - SBU); bioactive photoactivated varnish (PRG filler - SPRG). The degree of DH was analyzed using a visual analog scale (VAS) and computerized visual scale (CoVAS), before treatments and after 7, 15, and 30 days from the first session.

Adhesion and sealing of different universal adhesive systems associated with bulk-fill resins after using endodontic irrigation solutions: An in vitro study.

This study aimed to evaluate the interface of universal adhesive (UA) with bulk-fill resin (BF) and dentin, after endodontic irrigation. The pulp chamber of 96 molars was irrigated with chlorhexidine 2% (CHX) or sodium hypochlorite 5.25% (NaOCl) and restored according to three restorative protocols.

Fluorescence intensity of composite resin for direct veneer removal using a fluorescence-aided identification technique.

Objectives: This laboratory study evaluated the influence of the fluorescence intensity of composite resins on additional tooth wear and the presence of restorative material in different dental thirds during the retreatment of direct veneers.

Materials And Methods: The crown dimensions of 60 bovine incisors were reduced to 10 × 8 mm. The teeth were classified according to the fluorescence intensity of the composites: low (LOW) (TPH Spectra), medium (MED) (Opallis), and high (HIGH) (Essentia) groups.

Influence of dental bleaching on the pulp tissue: A systematic review of in vivo studies.

Background: Although several studies indicate the harmful effects of bleaching on pulp tissue, the demand for this procedure using high concentrations of hydrogen peroxide (HP) is high.

Objectives: To investigate the influence of bleaching on the pulp tissue.

Methods: Electronic searches were conducted (PubMed/MEDLINE, Scopus, Cochrane Library and grey literature) until February 2021.
