Does the time interval after bleaching influence adhesion of orthodontic brackets?Objective: To test null hypothesis that no difference exists between effects at-home and in-office on shear bond strength (SBS) with bracket bonding at 4 different intervals dental bleaching.Methods: Ninety extracted human premolars were randomly divided into 9 groups (n = 10) according to methods used (at-home bleaching) storage in artificial saliva (30 min, 1 day, 2 weeks, 3 weeks before bonding).The control...

The effect of bleaching treatments containing added calcium and combined with neutral or acidic fluoride gels on tooth enamel was investigated in vitro through Knoop microhardness (KHN) surface roughness (SR) measurements. A total 60 bovine incisors were tested, including 30 for SR measurements KHN specimens divided into 12 groups subjected to a agent hydrogen peroxide 35% (Whiteness HP Maxx, FGM) Blue Calcium, treatment flugel acidulated phosphate (APF) (NF). Control submitted without...

ABSTRACT Objective: This in vitro study analyzed the effects of a bleaching treatment containing 35% hydrogen peroxide (HP) with or without calcium on bovine enamel, using Knoop hardness number (KHN), tristimulus colorimetry (TC), and scanning electron microscopy. Materials Methods: Forty-five specimens were randomly divided into groups (n = 5), which included artificial saliva (negative control [NC]), HP (positive [PC]), Blue Calcium (HP Blue). The subjected to three sessions. During...

Objective This randomized controlled clinical trial aimed to evaluate the effect of casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF) and photobiomodulation (PBM) in treatment dentin hypersensitivity (DH), impact this on health-related quality life (HRQL). Methods Eighty teeth with DH were into four groups received three sessions: PLACEBO = placebo + LASER application mimicking; CPP-ACPF PBM active application; CPP-ACPF+PBM application. Tactile (exploratory probe)...

Abstract Objective The aim of this double‐blind, randomized, controlled clinical study was to assess the efficacy low‐level laser therapy (LLLT) combined with 5000 ppm fluoride dentifrice on postbleaching sensitivity in teeth exposed 35% hydrogen peroxide for four weeks. Materials and Methods Twenty‐five volunteers were evaluated using split‐mouth model which right left maxillary/mandibular quadrants randomized allocated one two groups: GPLACEBO, tip positioned without emission light...

The aim of this in vitro study was to assess the bond strength self-etching adhesives containing HEMA and 10-MDP monomers. Twenty-four bovine teeth were divided into three groups. Two cylinders composite resin made each tooth (n = 16): G1-Prime Bond Universal (control); G2-OptiBond All-in-One (HEMA); G3-Clearfil SE (10-MDP HEMA). After 24-hour storage distilled water, specimens fixed a universal testing machine (Kratos Equipamentos Ltda.) for microshear test at speed 0.5 mm/min. A...

Objective This split-mouth randomized controlled clinical trial assessed the effect of 10% strontium chloride in combination with photobiomodulation (PBM) for control tooth sensitivity (TS) post-bleaching. Methods The upper/lower, right and left quadrants fifty volunteers were allocated to four groups (n = 25): PLACEBO—placebo gel + simulation PBM; Placebo STRONTIUM—10% PBM PBM. All received bleaching treatment 35% hydrogen peroxide. For treatment, laser tip was positioned apical cervical...

The objective of this work was to evaluate the relationship between factors associated with COVID-19 pandemic and depression, anxiety, stress (DAS) in dentists. Factors were evaluated using a questionnaire scores Depression, Anxiety, Stress Scales-21 measured. differences DAS based on tested through successive application multivariate analysis variance (MANOVA, α = 0.05). After sample size calculation, 998 participants mean age 39.39 (± 11.69) years included. effect indicated that changes...

Objective This clinical trial evaluated the effect of 1.5% potassium oxalate (PO) in controlling sensitivity and color change after at-home tooth whitening. It also influence PO on health-related quality life (HRQoL) degree patient satisfaction bleaching treatment. Materials methods Fifty volunteers were randomized into two groups (n = 25): At-home gel with 22% carbamide peroxide for 45 min + placebo (GP) or (GPO) 10 min. The intensity was assessed daily through visual analog scale. analysis...

The photo-acceleration of bleaching gels by lights has been extensively researched. However, the induced temperature increase during this process needs to be further evaluated prevent damage dental pulp. Therefore, objective study was evaluate surface and intrapulpal kinetics different concentrations hydrogen peroxide (HP) photo-accelerated blue or violet light infrared laser.

Background . Propolis is a natural bee product that has garnered attention due to its harmlessness and numerous beneficial biological properties. This randomized, double‐blinded, placebo‐controlled clinical trial aimed assess the effect of toothpastes containing different concentrations propolis (10% 15%) on control dentin hypersensitivity (DH). Methods From adults aged 18–40 years with DH, 66 teeth were randomly divided into 3 treatment groups as follows ( n = 22): (toothpaste without...

This study compared the compressive strength of a composite resin and compomer photoactivated with conventional quartz-tungsten halogen-light (XL 3000, 3M/SPE) blue light-emitting diode (LED) (SmartLite PS; Dentsply/De Trey). Forty disc-shaped specimens were prepared using split polytetrafluoroethylene matrix (4.0 mm diameter x 8.0 hight) in which materials inserted incrementally. The curing time each increment was 40 s QTH 10 LED. randomly assigned to 4 groups (n=10), according light source...
