Evaluating the Dental Hygienists' Exposure to the Risk of Musculoskeletal Disorders.

Objectives:  The aim of the study was to evaluate dental hygienists' exposure to the risk of musculoskeletal disorders (MSDs), by the worksheets compatible with the Rapid Entire Body Assessment (REBA).

Materials And Methods:  The research included 272 dental hygienists aged 23 to 52 years from the two administrative regions of Poland.

Statistical Analysis:  STATISTICA 12 and Microsoft Excel were used to analyse the results.

Long COVID Oral Cavity Symptoms Based on Selected Clinical Cases.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is characterized by variable clinical features, different durations, and several previously unheard-of late complications. Knowledge about this infection is constantly evolving.The aim of the study is to present selected cases of the most common symptoms of long COVID in the oral cavity.

Comparison of Dental Stone Models and Their 3D Printed Acrylic Replicas for the Accuracy and Mechanical Properties.

This study was conducted to test possibilities of application of 3D printed dental models (DMs) in terms of their accuracy and physical properties. In this work, stone models of mandibles were cast from alginate impressions of 10 patients and scanned in order to obtain 3D printed acrylic replicas. The diagnostic value was tested as matching of model scans on three levels: peak of cusps, occlusal surface, and all teeth surfaces.

Minimally Invasive Transcrestal Sinus Floor Elevation Procedure in Severely Atrophic Ridge: A Case Report.

Typically, the greater the atrophy of the process, the more extensive and invasive the sinus floor elevation procedure is. This case of a 39-year-old man demonstrates a minimally invasive hydrostatic sinus lift from 1.7-mm height process in the site of lost tooth No.

Repeatability of Freehand Implantations Supported with Universal Plastic Sleeves-In Vitro Study.

Repeatability and precision are major factors which have an influence on final implant treatment results. The aim of this study was to evaluate the repeatability of freehand implant procedures assisted with special plastic sleeves which are placed on the drill to guarantee the proper mesiodistal distance from the landmark's surface. Patient data required for implant treatment, including images of mandibles from CBCT scans and virtual models of soft tissues and teeth, were used to prepare complete virtual models of patient clinical conditions.

Assessment of Hypodontia Treatment of Maxillary Lateral Incisors in Adult Patients After 9 Years of Follow-up: A Retrospective Study.

Purpose: To assess the effects of maxillary lateral incisor hypodontia treatment following the use of implantation procedures, fixed and removable dental prostheses, and change in the shape of the canine.

Materials And Methods: Hypodontia treatment effects were retrospectively evaluated in 129 patients aged 18 to 60 years. The assessment covered esthetic, biologic, and functional aspects of the restored missing teeth within 9 years after treatment.

Assessment of the influence of selected electrolytic polishing process parameters on the surface roughness of casts made of the CoCrMo alloy.

Background: To fabricate some prosthetic restorations, such as metal alloy frameworks for removable partial dentures (RPDs), casting techniques must be used. The penultimate stage of the cast finishing procedure is electropolishing.

Objectives: The aim of the study was to assess the influence of selected electrolytic polishing process parameters on the resulting surface smoothness of the cobalt-chromium-molybdenum (CoCrMo) alloy.

Fluoride penetration from three orthodontic adhesives: an experimental study.

Objective: To examine the prophylactic potential of 3 orthodontic bonding adhesives: Fuji Ortho SC, Illuminate, and Resilience.

Methods: Thirty-six Wistar Wag rats were randomly divided into 4 groups consisting of 9 rats each. One of the groups received no treatment and was used as a control.
