Tribochemical silicoating of amalgam promotes effective amalgam-resin repairs.

The purpose of this study was to determine the most effective method for bonding composite resin to artificially aged amalgam. A spherical amalgam alloy was triturated and condensed by hand into cylindrical plastic molds (6 mm in diameter and 4 mm in height) to create 90 specimens, which were then aged for 2 weeks in closed plastic containers at 23°C. The amalgam surfaces underwent 1 of 3 surface treatments (n = 30 per treatment): (1) air particle abrasion (APA) with 50-μm aluminum oxide particles applied with a force of 45 psi from a 10-mm distance, followed by rinsing with deionized water for 60 seconds; (2) APA following the same protocol with subsequent application of a metal primer (Alloy Primer); or (3) coating with 30-μm silica (CoJet) at a force of 45 psi from a 10-mm distance until the surface turned black.

Bilateral, Sequential Sudden Hearing Loss in a Patient With Multiple COVID-19 Infections and Potential Implications on Subsequent Cochlear Implant Performance.

Viruses are often implicated as a cause of sensorineural hearing loss (SNHL), particularly sudden cases, including COVID-19. Determining the viral mechanism that leads to hearing loss is necessary for its future prevention and treatment. The 47-year-old woman who is the subject of this case study presented with sudden SNHL following multiple infections of COVID-19.

Repair of noise-induced damage to stereocilia F-actin cores is facilitated by XIRP2 and its novel mechanosensor domain.

Prolonged exposure to loud noise has been shown to affect inner ear sensory hair cells in a variety of deleterious manners, including damaging the stereocilia core. The damaged sites can be visualized as 'gaps' in phalloidin staining of F-actin, and the enrichment of monomeric actin at these sites, along with an actin nucleator and crosslinker, suggests that localized remodeling occurs to repair the broken filaments. Herein, we show that gaps in mouse auditory hair cells are largely repaired within 1 week of traumatic noise exposure through the incorporation of newly synthesized actin.

Investigating correlations between the PAT and three hand-skill exercises to performance in preclinical laboratory courses.

Wax carving exercises predict performance on practical examinations for first-year dental students.

Unlabelled: Perceptual ability test (PAT) is a valid determinant for spatial perceptions. However, a validated psychomotor skill test for dentistry does not currently exist.

Purpose/objectives: This study aimed to determine whether the results of two wax carving exercises (E1 and E2), PAT, quantitative reasoning (QR), and academic average (AA) tests predict students' performance on dental anatomy practical examinations.

An evaluation of factors affecting dental shade matching in first-year dental students.

Statement Of Problem: Shade selection has become more important and challenging as it becomes more emphasized in esthetic dentistry. It would be beneficial to screen dental students early in their predoctoral education for any deficiencies in color discrimination. Specific tests that reliably predict dental shade-matching ability have not been fully established.

Perceptual ability tests correlate to performance on a rudimentary dental anatomy laboratory exercise.

Purpose: Objective of this study was to determine if perceptual abilities test (PAT), quantitative reasoning (QR), and academic average (AA) scores predict performance in a rudimentary dental anatomy laboratory exercise.

Methods: First-year dental students (n = 88) completed two identical wax carving exercises during the first and last weeks of the dental anatomy course. After being given detailed instructions and a wax block, students carved a cube and a semilunar shape using the wax subtraction technique.
