Exploring dental academics' perceptions of and experience with discrimination in the UK and Ireland: a qualitative study.

Introduction Diversity is known to be important but diversity of dental school academics in the UK and Ireland is low in comparison with the dental profession and the overall population. The aims were to explore whether UK and Ireland dental school academics are satisfied with their career progression, whether they believe that there are barriers to career progression in dental schools based on protected characteristics, and experience of discrimination at work.Methods An online survey, including four free-text questions related to the study aims, was circulated by the Dental Schools Council to dental academics at all UK and Ireland dental schools.

Nanocryl Coating of PMMA Complete Denture Base Materials to Prevent Scratching.

The surface of polymethylmethacrylate (PMMA) is vulnerable to indentation by hard objects that may contribute to abrade the material surface and subject it to wear. This phenomenon promotes an increase in the surface roughness leading to microbial colonisation which can endanger the general health of wearers and damage the intra-oral prosthesis. The aim of this study is to investigate the effect of three different nanocryl coating agents (Easy Glaze, G-Coat Plus and Formulation XP) on surface roughness and thickness of PMMA material after a simulating cleaning process utilizing an electric toothbrush and three different dentifrices (pastes and immersion).

The Accuracy of Fit of Crowns Made From Wax Patterns Produced Conventionally (Hand Formed) and Via CAD/CAM Technology.

Objective: The aim of this study was to compare the marginal and internal fit accuracy of crowns constructed using three different wax production methods; conventional, milled, and 3D printed and utilizing three different cement gap thicknesses.

Methods: 15 identical stone dies were made for each method. Wax patterns were produced and then cast into metal crowns, which were assessed for differences in accuracy of both marginal and internal fit.

The effect of TiO2 concentration on properties of apatite-mullite glass-ceramics for dental use.

Objective: The aim of this study was to evaluate the effect of TiO2 concentration on the properties of apatite-mullite glass-ceramics namely strength and the chemical solubility to comply with the ISO standard recommendations for dental ceramics (BS EN ISO 6872-2008).

Methods: Ten novel glass-ceramic materials were produced based on the general formula (4.5SiO2-3Al2O3-1.

The effect of ZrO2 and TiO 2 on solubility and strength of apatite-mullite glass-ceramics for dental applications.

The effect of ZrO2 and TiO2 on the chemical and mechanical properties of apatite-mullite glass-ceramics was investigated after sample preparation according to the ISO (2768:2008) recommendations for dental ceramics. All materials were characterized using differential thermal analysis, X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. X-ray fluorescence spectroscopy was used to determine the concentrations of elements present in all materials produced.

The effect of calcium fluoride (CaF(2)) on the chemical solubility of an apatite-mullite glass-ceramic material.

Objective: To assess the effect of varying CaF(2) on the chemical solubility of apatite-mullite glass-ceramic (G-C) materials in both the glassy and crystallized states.

Methods: Apatite-mullite forming glasses used in this study are ionomer cement derivatives based on the general formula (4.5SiO(2)-3Al(2)O(3)-1.

The influence of calcium fluoride (CaF2) on biaxial flexural strength of apatite-mullite glass-ceramic materials.

Objective: The aim of this study was to evaluate the effect of varying the molar percentage of calcium fluoride (CaF2) on the biaxial flexural strength (BFS) of apatite-mullite glass-ceramics.

Methods: Three apatite-mullite glass-ceramic materials were produced based on a formula of 4.5SiO(2)-3Al2O(3)-1.
