Discriminatory episodes negatively impact the quality of life of Brazilian dental students: A cross-sectional study.

Purpose: This study aimed to evaluate whether discriminatory episodes occurring in the university environment were associated with dental students' self-perceived overall quality of life and assess the cumulative effect of perceived discriminatory experiences on the overall quality of life.

Methods: In this cross-sectional study, all students enrolled in three Brazilian dental schools were invited to participate in a survey between August and October 2019. The outcome was students' self-perceived quality of life, measured through the overall quality of life item of the World Health Organization-Quality of Life Abbreviated Version (WHOQOL-BREF).

Discrimination and dental students: What is the reality in Brazilian institutions?

Introduction: This study aimed to evaluate whether there is discrimination in the dental educational environment, assess the main reasons for the discriminatory events, and if there is an association between discriminatory episodes and sociodemographic characteristics of undergraduate dental students.

Materials And Methods: This observational cross-sectional study was conducted with a self-administered questionnaire to students enrolled in three Brazilian dental schools. Questions included sociodemographic characteristics and the occurrence of discriminatory episodes in the dental academic environment.

In-vitro models of biocompatibility testing for restorative dental materials: From 2D cultures to organs on-a-chip.

Dental caries is a biofilm-mediated, diet-modulated, multifactorial and dynamic disease that affects more than 90% of adults in Western countries. The current treatment for decayed tissue is based on using materials to replace the lost enamel or dentin. More than 500 million dental restorations are placed annually worldwide, and materials used for these purposes either directly or indirectly interact with dentin and pulp tissues.

Is dentin biomodification with collagen cross-linking agents effective for improving dentin adhesion? A systematic review and meta-analysis.

Objectives: The aim of this investigation was to evaluate the effectiveness of collagen cross-linking agents (CCLAs) used in combination with the adhesive technique in restorative procedures.

Materials And Methods: In this systematic review, the authors followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. An electronic search was performed using PubMed, Scopus, Web of Science, Cochrane Library, LILACS, and DOSS, up to October 2020.

Physicochemical and microbiological assessment of a dental adhesive doped with cashew nut shell liquid.

To evaluate i) the inhibitory and bactericidal activity of cashew nut shell liquid (CNSL) and its isolated compounds (anacardic acid and cardol) against oral bacteria; ii) the biofilm formation inhibition, resin-dentin bond strength and physicochemical properties of a dental adhesive incorporated with these substances. The antibacterial effect of CNSL, anacardic acid, and cardol were assessed by determining the minimum inhibitory (MIC) and minimum bactericidal (MBC) concentrations. Effect in inhibiting biofilm formation of the adhesive incorporated with the substances (15 μg/ml) against a mixed-species biofilm of Streptococcus mutans and Candida Albicans and was determined by direct contact test.

Cashew nut shell liquids: Antimicrobial compounds in prevention and control of the oral biofilms.

Objective: The aim was to evaluate the antibacterial and antibiofilm activity of natural (n-CNSL) and technical (t-CNSL) cashew nut shell liquid against streptococci and enterococci related to dental caries and chronic apical periodontitis, respectively.

Material And Methods: Minimum inhibitory concentrations (MIC) and minimal bactericidal concentration (MBC) were determined to assess the antimicrobial effect of both CNSLs (n-CSNL and t-CNSL) against S. oralis ATCC 10557, S.

Influence of the degree of conversion and Bis-GMA residues of bulk fill resins on tissue toxicity in an subcutaneous model in rats.

Aim: To analyse the influence of the degree of conversion (DC) and light curing residues of different bulk fills (BFs) composites on the inflammatory profile in the subcutaneous tissue of rats.

Materials And Methods: Resin disks of BF-resins and their active conventional resins (CR; 3M®, Ivoclar®, and Kerr®) were light-cured at 2 mm (BF-superficial) and 4 mm (BF-deep) thicknesses and analyzed by infrared spectroscopy (FTIR;  = 3/group; DC and light curing residues). Then, the disks were implanted in four quadrants in the subcutaneous tissue of Wistar rats (sham, CR, BF-superficial and RF-deep), and after 7, 14, and 28 days, the animals ( = 6/day) were euthanized for histological analysis of the intensity of the inflammatory process (scores 0-3).

Clinically relevant outcomes in dental clinical trials: challenges and proposals.

The impact of clinical trials on patient care depends on the outcomes that they evaluate. In Dentistry, many trials use outcomes that are important to clinicians, but not to the patients. Thus, the aim of the present manuscript is to present an overview of the limitations, challenges, and proposals on the use of clinically relevant outcomes (CRO) in dental trials.

Two-year clinical evaluation of a proanthocyanidins-based primer in non-carious cervical lesions: A double-blind randomized clinical trial.

Objectives: This double-blind randomized clinical trial evaluated the influence of pre-treatment with proanthocyanidins (PA) from grape seed extract on the clinical behavior of a simplified etch-and-rinse adhesive placed in non-carious cervical lesions (NCCLs) over 6- and 24-months.

Materials And Methods: A total of 135 restorations were randomly inserted in 45 subjects. The NCCLs were etched with 37 % phosphoric acid for 15 s and distributed into 3 groups: Control (PA0) - adhesive ExciTE F applied as per the manufacturer's recommendations; PA2 and PA5 groups - 2 wt% and 5 wt% PA solution, respectively, were applied for 60 s and washed for 30 s prior to application of the adhesive.

Ethanol as Dentin Pretreatment on the Bonding Performance of a Two-Step Etch-and-Rinse Adhesive: An In Vivo Study.

Objective: The aim of this study was to evaluate the use of 70 vol.% ethanol as a dentin pretreatment on the bond strength (BS) of a two-step etch-and-rinse adhesive.

Materials And Methods: Resin composite Class I restorations were clinically bonded to acid-etched dentin of human sound third molars using Adper Single Bond 2 (SB, 3M ESPE) and randomly divided into two major groups: dentin saturated with water (control) or 70 vol.

Two-year clinical evaluation of proanthocyanidins added to a two-step etch-and-rinse adhesive.

Objective: To compare the clinical behavior of Proanthocyanidins (PA)-free and PA-containing two-step etch-and-rinse adhesive used underneath resin composite restorations in non-carious cervical lesions (NCCLs) over a 6- (6 M) and 24-month (24 M) period.

Methods: 135 restorations were randomly placed in 45 subjects. The NCCLs were conditioned (37% phosphoric acid for 15 s) and distributed into 3 groups: Control (EX0) - ExciTE F (Ivoclar Vivadent) adhesive applied following the manufacturer's recommendations; EX2 and EX5 - 2 wt% and 5 wt% of PA were added to ExciTE F, respectively, and applied as in EX0.
