The Role of Digital Facebow for CAD/CAM Implant-Supported Crowns Workflow.

Recent advancements in digital technologies have transformed clinical workflows in dentistry, ensuring precise restorations. Custom-made crowns and fixed partial dentures (FPDs) now rely on virtual articulation. The digital facebow provides individualized data for CAD settings, streamlining the fabrication via digital workflow.

Changes in spinal curve during dentistry studies measured with a Spinal Mouse device: A five-year prospective study.

Introduction: Musculoskeletal disorders (MSDs) often arise and develop during dentistry studies. The most affected regions are related to the spine. Possible associations between spinal curve parameters and MSDs have not yet been investigated amongst dentistry students.

Low, medium, and high molecular weight hyaluronic acid effects on human dental pulp stem cells in vitro.

Hyaluronic acid (HA), an extracellular biopolymer found throughout the human body, holds promise as a biocompatible and biodegradable scaffold material. High molecular weight (HMW) HA degrades, generating low molecular weight (LMW) fragments with distinct properties. These fragments can influence the behaviour of cells, including human dental pulp stem cells (hDPSCs) incorporated into HA-containing hydrogels or scaffolds.

Patient-reported outcome measures (PROMs) of digital and conventional impression methods for fixed dentures.

Background: Digital impression technique or computer-aided impression (CAI) has been recently concluded as a clinically acceptable alternative to conventional impression method (CIM) in the fabrication of crowns, short fixed partial dentures (FPDs), and implant-supported crowns.

Objective: The purpose of this study was to investigate the patients' opinion and subjective perception of two different ways of impression - digital and conventional.

Methods: A total of 45 patients were treated with CAI and CIM for the fabrication of tooth or implant-supported crowns.

COVID-19 among Czech Dentistry Students: Higher Vaccination and Lower Prevalence Compared to General Population Counterparts.

The restrictions on medical students’ clinical education during the COVID-19 pandemic has affected their professional readiness and often lengthened their training. These negative impacts are often considered a necessary price as clinical education is hypothesized to be associated with a high risk of pandemic spread. This work assesses this hypothesis based on COVID-19 epidemiological data among Czech dentistry students and their comparison to data of the Czech general population of similar age.

The Prevalence and Development of Neck and Lower Back Pain and Associated Factors in Dentistry Students-A Long-Term Prospective Study.

Musculoskeletal disorders (MSDs) represent a significant occupational burden for dentists and dentistry students. This study aimed to assess the five-year development of most common musculoskeletal complaints among dentistry students during the whole length of their studies and to analyze the impact of some potentially associated risk factors. A longitudinal questionnaire survey regarding the occurrence of MSDs was conducted among a total of 73 dentistry students between 2014 and 2021.

Initial Observation of Factors Interfering with the Treatment of Alveolar Osteitis Using Hyaluronic Acid with Octenidine-A Series of Case Reports.

Alveolar osteitis (AO) is a common complication following the extraction of the teeth, particularly the lower third molars. It starts within a few days after the extraction and manifests mainly as pain in the extraction site. Several strategies of treatment are available in order to relieve pain and heal the extraction wound.

The Development of Musculoskeletal Disorders during Undergraduate Dentistry Studies-A Long-Term Prospective Study.

Musculoskeletal disorders (MSDs) frequently occur among dental practitioners and present a significant occupational burden with an early onset in the dentists' career. This study aimed to analyze the five-year development of self-reported overall MSDs among the dentistry students during the course of their studies and to assess the possible influence of the risk as well as protective factors. The questionnaire inquiry was performed among the first-year dentistry students, regarding the occurrence of MSDs and the presence of potential risk and protective factors.

A Review of Evidence-Based Recommendations for Pericoronitis Management and a Systematic Review of Antibiotic Prescribing for Pericoronitis among Dentists: Inappropriate Pericoronitis Treatment Is a Critical Factor of Antibiotic Overuse in Dentistry.

This work provides a narrative review covering evidence-based recommendations for pericoronitis management (Part A) and a systematic review of antibiotic prescribing for pericoronitis from January 2000 to May 2021 (Part B). Part A presents the most recent, clinically significant, and evidence-based guidance for pericoronitis diagnosis and proper treatment recommending the local therapy over antibiotic prescribing, which should be reserved for severe conditions. The systematic review includes publications analyzing sets of patients treated for pericoronitis and questionnaires that identified dentists' therapeutic approaches to pericoronitis.

Assessment of local muscular load of dental practitioners.

Objective: Hands and forearms are one of the most common localisations of musculoskeletal disorders (MSDs) among dental practitioners. The aim of this study was to objectively assess the local muscular load of hands and forearms of dental practitioners during various treatment procedures using the method of the integrated electromyography (iEMG). This method is used for health risk assessment and categorization of working operation within the official national methodology.

Perception of Undergraduate Students at the Faculty of Medicine in Hradec Králové Regarding Their Endodontic Education and Suggested Improvements.

Aim: The aim of this study was to assess the perception of undergraduate dentistry students at Charles University, Faculty of Medicine in Hradec Králové, the Czech Republic regarding their endodontic education within the context of the Undergraduate Curriculum Guidelines for Endodontology by the European Society of Endodontology (ESE). The secondary aim was to compare this perception among students in the Czech and English groups.

Methodology: A questionnaire survey was conducted among fifth year students at the very end of their studies.

Exposure to mercury from dental amalgam: actual contribution for risk assessment.

Objective: Mercury dental amalgam restorations are an important source of chronic exposure to mercury in the whole population and special attention should be paid not only to occupational exposure to mercury during the preparation and administration of amalgam. The authors' report is an up-to-date contribution to the health risk assessment of mercury use in dentistry, namely occupational exposure to mercury in dentists working with dental amalgam and exposure to mercury in persons treated with amalgam dental restorations.

Methods: Determination of total mercury in samples of biological material (urine, hair) was performed during 2017 and 2018 in 50 persons by the AAS method using the mercury vapour generation technique at 254.

Prevalence of Musculoskeletal Disorders Symptoms Among Czech Dental Students. Part 2: The Predictive Value of Digital Assessment.

This article is the second part of an evaluation of musculoskeletal disorders (MSDs) prevalence among dental students. As the majority of complaints are in the back region, there is an endeavor to analyze objectively the disorders in this region. One of the non-invasive and non-radiation methods is the spinal curve mapping using the Spinal Mouse® device (Idiag AG, Fehraltorf, Switzerland).

Prevalence of Musculoskeletal Disorders Symptoms among Czech Dental Students. Part 1: a Questionnaire Survey.

A comparison of different rubber dam systems on a dental simulator.

The purpose of this study was to test the hypothesis that more recently developed rubber dam systems (OptraDam ® Plus and OptiDam™) are faster and easier to handle, and that the quality of isolation is not decreased. The rubber dam systems were applied in standard conditions on a dental simulator in several model clinical situations. The time of preparation, application and removal were measured and the quality of isolation was evaluated.
