Effect of Printing Layer Thickness and Postprinting Conditions on the Flexural Strength and Hardness of a 3D-Printed Resin.

Background: Recently, dentists can utilize three-dimensional printing technology in fabricating dental restoration. However, to date, there is a lack of evidence regarding the effect of printing layer thicknesses and postprinting on the mechanical properties of the 3D-printed temporary restorations with the additive manufacturing technique. So, this study evaluated the mechanical properties of a 3D-printed dental resin material with different printing layer thicknesses and postprinting methods.

Aesthetic monitoring-based assessment of oncological safety of oncoplastic management of breast cancer: a multi-center research study.

Background: Oncoplastic Breast surgeries (OBS) in breast cancer have evolved to preserve the cancerous breast rather than its amputation to improve postoperative cosmetic results. The lack of evidence to support the oncological safety and benefits of OBS is questionable. In this study, we evaluate various aspects of oncoplastic surgeries with a focused monitoring of aesthetic results and oncological safety.

Epidemiology of Abusive Head Trauma Among Children in Saudi Arabia.

Background And Objectives: To examine abusive head trauma (AHT) trends using data obtained from hospital-based child protection centers (CPCs) and the distribution of age in months among young children in Saudi Arabia.

Methods: A retrospective study was conducted that includes data obtained from 58 hospital-based CPCs in all 13 regions of Saudi Arabia registered in the National Family Safety Registry from 2010 to 2020. AHT cases (n=106) were identified for inclusion in the registry by a daily review of the emergency department logbooks.

Detection of chikungunya virus in the Southern region, Saudi Arabia.

Background And Aim: Despite the fact that the chikungunya viral infection is a neglected disease, complications such as hemorrhagic fever, arthritis, and lymphopenia remain a health concern. The aim of this study was to determine the prevalence of the chikungunya virus in the Southern Region, Saudi Arabia. Enzyme immunoassay and polymerase chain reaction have been compared between samples.

Point-of-Care Ultrasound Training: An Assessment of Interns' Needs and Barriers to Training.

Background and objective The use of point-of-care ultrasound (POCUS) is generally on the rise worldwide. However, as the epidemiology of diseases and the approach to their management vary internationally, POCUS may not be universally applicable. The resources available for medical education are generally limited.

Effect of ionizing radiation on mechanical properties and translucency of monolithic zirconia.

This study aimed to evaluate the effect of radiation therapy (RT) on mechanical properties and translucency of monolithic zirconia. Yttria- stabilized zirconia (Y-PSZ) materials (14 × 4.0 × 1.
