Unraveling the signs and symptoms of oral conditions that affect daily life activities and oral health-related quality of life.

Objectives: Since oral conditions negatively affect oral health-related quality of life (OHRQoL), this study evaluated which oral clinical condition, signs, and symptoms are associated with the impact on OHRQoL, its domains, and specific daily life activities among adults.

Materials And Methods: Data from a probabilistic sample of adults (35-44 years old) was used. The Oral Impacts on Daily Performance (OIDP) was used to evaluate OHRQoL, its domains (physical, psychological, and social), and nine daily life activities.

Effect of thickness and CAD-CAM material on fatigue resistance of endodontically treated molars restored with occlusal veneers.

Purpose: To evaluate the influence of the thickness and type of computer-aided design and computer-aided manufacturing (CAD-CAM) material on the fatigue resistance and failure mode of endodontically treated teeth (ETT) restored with occlusal veneers (OV).

Materials And Methods: Seventy-five (N = 75) ETT were restored with Herculite XRV in the endodontic access. Five experimental groups (n = 15) were tested.

Influence of Adhesion Promoter Primers on Polymerization Kinetics and Long-term Bond Strength of Composite Cements to Zirconia.

Purpose: To investigate the influence of primers on polymerization kinetics of resin-based luting and its effect on the microhardness and bond strength to zirconia. Materials and Methods: Panavia V5 (PV; Kuraray Noritake) with Tooth Primer (TPprimer; Kuraray Noritake) or Clearfil Ceramic Primer (CPprimer; Kuraray Noritake), and RelyX Ultimate (RU; 3M Oral Care) with Scotchbond Universal (SUadhesive; 3M Oral Care) were evaluated. Polymerization kinetics of luting materials with or without primers (TPprimer or SUadhesive) were evaluated using Fourier transform near-infrared (FT-NIR) spectroscopy in self- and dual-curing modes (n = 5).

DOES TITANIUM TETRAFLUORIDE PROMOTE A PROTECTIVE EFFECT ON ERODED TOOTH? A SYSTEMATIC REVIEW AND META-ANALYSIS.

Objective: This systematic review and meta-analyses aimed to evaluate the potential protective effect of titanium tetrafluoride (TiF) compound compared to sodium fluoride (NaF) on eroded enamel or dentin.

Methods: Two independent reviewers searched PubMed, Scopus, Web of Science, LILACS, Cochrane, EMBASE, and Open gray Literature up to June 2020. MeSH terms, supplementary concepts, synonyms, and free terms were applied based on PICOS strategy (P- population: eroded enamel or dentin; I- intervention: eroded teeth treated with solution or varnish of TiF; C- comparison: eroded teeth treated with a solution or varnish of NaF; O- outcome: mineral loss measurement; S- study design: in vitro studies).

Adhesion of Resin Cement to Zirconia Using Argon Plasma and Primer.

Purpose: To evaluate the effectiveness of nonthermal atmospheric plasma (NTAP) and priming on the shear bond strength (SBS) of a resin cement to two zirconia ceramics after 24 hours and 1 year of water storage.

Materials And Methods: A total of 120 plates (9 x 7 x 2 mm) were obtained from two types of zirconia (Katana, Kuraray Noritake; and ZirCAD, Ivoclar Vivadent) plates randomly divided into 12 groups (n = 10 each). Zirconia ceramic plates were submitted to the following treatments: (1) untreated (control); (2) treated with ZPrime Plus (Bisco Dental) primer; (3) NTAP (Surface Plasma Tool Model SAP, Surface Engineering and Plasma Solution) application for 10 seconds; (4) NTAP for 30 seconds; (5) NTAP for 10 seconds followed by priming; and (6) NTAP for 30 seconds followed by priming.

Effect of zirconia decontamination protocols on bond strength and surface wettability.

Objective: To evaluate the effects of human saliva decontamination protocols on bond strength of resin cement to zirconia (Y-PSZ), wettability, and microbial decontamination.

Materials And Methods: Zirconia plates were sandblasted and divided into (a) not contaminated, (b) contaminated with human saliva and: (c) not cleaned, (d) cleaned with air-water spray, (e) cleaned with 70% ethanol, (f) cleaned with Ivoclean, or (g) cleaned with nonthermal atmospheric plasma (NTAP). The wettability and microbial decontamination of the surfaces were determined after saliva contamination or cleaning.

[Dissatisfaction with dental services among dentate and edentulous elderly Brazilians: a multilevel analysis].

The scope of this study was to evaluate dissatisfaction with dental services among dentate and edentulous elderly Brazilians and its association with contextual and individual variables. The data from the National Oral Health Survey conducted in 2010 and contextual variables related to cities were used. Descriptive, bivariate and multilevel analysis was conducted among 1,989 elderly individuals.

Impact of untreated dental caries on the daily activities of children.

Objectives: Untreated dental caries can compromise oral health-related quality of life (OHRQoL). However, it is not clear which specific daily activities related to OHRQoL are compromised by the presence of this problem. Therefore, the purpose of this study was to identify which specific daily activities are affected by the presence of untreated dental caries using a representative sample of Brazilian children.

Effect of Fluoride Concentration on Reduction of Enamel Demineralization According to the Cariogenic Challenge.

Fluoride present in toothpaste at 1,100 µg/g is considered effective on caries control. However, under high cariogenic challenge due to increasing sugar exposure, higher fluoride concentration (5,000 µg/g) could be necessary to compensate the unbalance on caries process. This was tested in a pH-cycling regimen, which evaluated the effect of fluoride concentration relative to toothpaste on reduction of enamel demineralization under conditions of two levels of cariogenic challenge.
