Dental students' Myers-Briggs Type Indicator personality profile in the past 50 years: Systematic review and meta-analysis.

Background: Dental students' personalities are strongly correlated with their didactic and clinical performances. With the significant changes in the social environment in the past decades, students' personalities may also change dramatically. Additionally, with the increasing number of international students admitted into US dental programs, educators must pay attention to the potential personality differences between domestic and international students.

Metronidazole may display anti-inflammatory features in periodontitis treatment: A scoping review.

Aim: Metronidazole (MTZ) is an antimicrobial agent used to treat anaerobic infections. It has been hypothesized that MTZ may also have anti-inflammatory properties, but the evidence is limited and has not been previously reviewed. Thus, this scoping review aimed to answer the following question: "What is the evidence supporting anti-inflammatory properties of metronidazole that are not mediated by its antimicrobial effects?"

Methods: A scoping review was conducted according to the PRISMA-ScR statement.

Background: Since color measurements are relative, the discrepancy among different instruments is alarmingly high. This multicenter study evaluated the effectiveness of instrument calibration and inter-instrument harmonization of different spectrophotometers with the same optical geometry using tooth-colored, translucent dental materials.

Methods: The coordinating center (CC) spectrophotometer was calibrated using the NPL Ceram Series II set.

Cannabinoids in Periodontology: Where Are We Now?

Introduction: Cannabinoids are a well-documented treatment modality for various immune and inflammatory diseases, including asthma, chronic obstructive pulmonary disease, Crohn's disease, arthritis, multiple sclerosis, and a range of neurodegenerative conditions. However, limited information is available regarding the therapeutic potential of cannabinoids in treating periodontal disease.

Objective: The objective of this study is to analyze the current evidence on the antibacterial and immunomodulatory effects of cannabis and its role in the healing and regeneration processes within periodontal tissues.

Staining- and aging-dependent changes in color and translucency of 3D-printed resin-modified ceramics.

Purpose: To evaluate staining- and aging-dependent changes in the color and translucency of 3D-printed resin-modified ceramics (RMC).

Methods: Specimens (n= 5 per condition and material) were fabricated from test materials: Permanent Crown Resin (PCR), Crowntec (CT), Vita Enamic (VE) and Tetric CAD (TC). Specimens were stained in wine, coffee, tea, and water (control) and exposed to artificial accelerated aging (AAA).

Disruption of causes craniofacial anomalies in developing zebrafish.

Craniofacial development is a complex and tightly regulated process and disruptions can lead to structural birth defects, the most common being nonsyndromic cleft lip and palate (NSCLP). Previously, we identified as a candidate regulator of NSCLP through family-based association studies, yet its specific contributions to oral and palatal formation are poorly understood. This study investigated the role of during zebrafish craniofacial development through genetic disruption and knockdown approaches.

Genome-wide Association Study Identifies Novel Risk Loci for Apical Periodontitis.

Introduction: Apical periodontitis (AP) is a common consequence of root canal infection leading to periapical bone resorption. Microbial and host genetic factors and their interactions have been shown to play a role in AP development and progression. Variations in a few genes have been reported in association with AP; however, the lack of genome-wide studies has hindered progress in understanding the molecular mechanisms involved.
