Simulation of an Orthodontic System Using the Lingual Technique Based on the Finite Element Method.

The finite element method (FEM) is an advanced numerical technique that can be applied in orthodontics to study tooth movements, stresses, and deformations that occur during orthodontic treatment. It is also useful for simulating and visualizing the biomechanical behavior of teeth, tissues, and orthodontic appliances in various clinical scenarios. The objective of this research was to analyze the mechanical behavior of teeth, tissues, and orthodontic appliances in various clinical scenarios.

Therapeutic Role of Secondary Metabolites from Probiotic Strains for Ehrlich Solid Tumors in Mice.

This study aimed to screen the bioactive components in Streptococcus equinus WC (SE-WC) and Limosilactobacillus reuteri GM (LR-GM) and estimate the therapeutic role in Ehrlich solid tumors (EST) mice model. Forty-four male albino EST mice were assigned into 7 groups and treated daily for 2 weeks, including the EST group, the EST mice that received SE-WC at a low or a high dose (0.5 ml *10 or 0.

Orthodontic System Modeled and Simulated with the Lingual Technique to Assess Tooth Forces.

CBCT (cone beam computed tomography) is an imaging investigation that provides three-dimensional (3D) images of craniofacial structures. The purpose of this study is to determine the mechanical behavior of an orthodontic system where the lingual treatment technique was used in a 25-year-old female patient from whom a set of CBCT scans was used. CBCT images were processed through software programs such as Invesalius, Geomagic, and Solid Works, to create models containing virtual solids.

Expert opinion on management of moderate-to-severe atopic dermatitis in Qatar.

Atopic dermatitis (AD), a chronic-relapsing inflammatory skin disorder, manifests with intense itching and eczematous lesions impairing quality of life. A heterogeneous population, and regional clinical practices for treating AD warrant the development of guidelines in Qatar. Therefore, guidelines for the management of moderate-to-severe AD in Qatar have been developed and discussed.

Mental wellbeing of frontline health workers post-pandemic: lessons learned and a way forward.

Objective: To assess the state of mental wellbeing among medical and dental frontline health workers as the COVID-19 pandemic transitions to an endemic phase and to determine what employer-provided intervention strategies these workers perceive as effective and desirable to improve their mental wellbeing.

Methods: An anonymous online survey distributed to frontline health workers in a hospitalist program of a tertiary care medical center and a university dental school in Minnesota in September 2022. The survey contained validated tools to measure depression severity, levels of perceived stress, and mental health status as well as questions to determine effective strategies to improve emotional wellbeing among these health workers.
