Qatar dental student perceptions of Sirona prep-check software for learning crown preparations.

Background: Contemporary dental education requires swift assimilation of technological advancements to prepare the future generation of dentists. Integrating digital tools, such as prepCheck software in crown preparations offers a promising avenue for enhancing the learning experiences of dental students. This study aimed to evaluate the perceptions and experiences of undergraduate dental students regarding the use of PrepCheck software for learning crown preparations.

Evaluation of relational factor in patient satisfaction with the treatment received by dental students.

Introduction: The study focused on the importance of the relational factor and empathy in the general satisfaction of patients for the treatment received by university dental students. To achieve this objective, a tool capable of evaluating the most humanistic dimensions (empathy, kindness, trust) in the development of dental treatment has been designed.

Materials And Methods: A review of the literature was carried out and, based on its findings, a questionnaire was designed to assess patient satisfaction with the dental student's empathy.

Local hormones and growth factors to enhance orthodontic tooth movement: A systematic review of animal studies.

Background: Prolonged treatment times are the main reason capable of affecting patient compliance with orthodontic treatment.

Objectives: A systematic review was made to determine whether the local administration of hormones and growth factors effectively enhances orthodontic tooth movement, and to identify possible adverse effects in animal studies.

Materials And Methods: Five databases (PubMed, Scopus, EMBASE, Web of Science and Cochrane Library) were checked for experimental studies reporting one of the following outcomes: orthodontic tooth movement, histological outcomes and side effects.

COVID-19 pandemic and its impact on dental students: A multi-institutional survey.

Purpose/objectives: To investigate dental students' perceptions and concerns regarding the COVID-19 pandemic, their coping strategies and support resources, and their perceived stress levels.

Methods: A customized 19-item survey and the perceived stress scale (PSS) were applied to undergraduate dental students from the US, Spain, Ireland, Chile, India, and Brazil between April 10 and July 5, 2020. Linear modeling and mediation analysis were used to explore the relationships among demographics, stressors, coping mechanisms, social support, and stress RESULTS: A total of 4475 students responded to the survey.

Influence of abutment height and surface roughness on in vitro retention of three luting agents.

Purpose: This study evaluated the effects of abutment height, airborne-particle abrasion, and type of cement on the tensile resistance to dislodgement of cement-retained implant restorations.

Materials And Methods: Three groups of 12 standardized abutments each were prepared with different heights (4 mm, 5 mm, and 6 mm) using a milling machine. Crowns were cast in cobalt-chrome using the lost-wax technique, airborne particle-abraded using 50-Μm aluminum oxide, and cleaned with acetone.
