Background: Failures in glass fiber post (GFP) retention may be associated with low adhesion achieved in root dentin.
Material And Methods: 55 single-rooted premolars were endodontically treated and distributed according to different adhesion strategies (n=11): G1: RelyX ARC (3M ESPE; etch-rinse strategy); G2: Relyx Ultimate (3M ESPE; etch-rinse strategy); G3: AllCem (FGM; etch-rinse strategy); G4: Relyx Ultimate (3M ESPE; self-etching strategy); G5: RelyX U200 (3M ESPE; self-adhesive strategy). For Bonding Strength (BS) analysis, the roots were sectioned in slices (1.
Background/aim: Due to the increase in incarceration rates, the prison community has attracted much concern in the recent past. Although people in prison are often socially disadvantaged and vulnerable to a range of health problems, there is a lack of information on the oral health conditions of prisoners. Thus, the aim of this study was to survey the oral problems of a sample of the male incarcerated population of Brazil, focusing on dental trauma.

Thus, the purpose of this study was to evaluate the color stability of bulk-fill resins when exposed to dye.
Material And Methods: Cavities were prepared in 80 bovine incisors, which were randomly assigned into 4 groups (n = 20) according with the resin composite used: P60 (Control Group - Filtek P60, 3M/ESPE), FP (Filtek Bulk-Fill Posterior, 3M/ESPE), SDR (SDR, Dentsply) and FF (Filtek Bulk Fill Flow, 3M/ESPE).
Background: Employing violet LED on tooth bleaching is a recent but promising technique. This study aimed to assess the bleaching effectiveness of violet light-emitting diodes (LEDs) associated or not with bleaching gels containing hydrogen peroxide (HP) or carbamide peroxide (CP).
Methods: seventy bovine incisors were randomly assigned into 7 groups (n = 10) according to the technique and whitening product used.
Article Synopsis
- The study examines how different polymerization methods affect the properties of composite resins used in dentistry, particularly their microhardness and strength.
- A total of 150 resin specimens were tested using three polymerization methods: light curing, photopolymerization with autoclave, and photopolymerization with microwave, across five different resin types.
- Results showed that light curing produced the highest microhardness values, while Brilliant Everglow resin consistently showed the lowest values, regardless of the polymerization method used.
Background: After dental bleaching procedures dentists commonly advise patients to reduce the consumption of beverages that may cause the teeth to stain, however, the effectiveness of teeth whitening may not be directly affected by diet.
Material And Methods: It was evaluated through in vitro study whether contact with dyes through in-office bleaching sessions with 35% hydrogen peroxide would influence the effectiveness of treatment. Sixty bovine incisors were randomly assigned into 5 groups (n = 12) according to contact frequency and type of dye solutions.
