Comparison of digitally assessed quality of posterior crown preparations performed with and without previous practice on patient-specific three-dimensional-printed teeth models.

Introduction: Three-dimensional (3D)-printing technology can provide customizable simulations, but its effects on patient care quality have not been well studied. This study aimed to assess the impact of practicing with patient-specific 3D-printed teeth models on the quality of patients' dental preparations performed by students transitioning to clinical training. Accordingly, the quality of posterior crown preparations was evaluated by objectively analyzing digital scans and grades in two groups: the study group, which practiced beforehand with patient-specific 3D-printed teeth models, and the control group, which did not practice with these models.

Midpalatal suture maturation in 15- to 35-year-olds: morphological assessment in the coronal plane using CBCT-an exploratory study.

Rapid maxillary expansion (RME) is used in patients presenting transverse maxillary deficiency. However, RME may be unpredictable after late adolescence if the midpalatal sutural maturation stage (MPMS) is in late stage. Since MPMS evaluation is influenced by the expertise of the operator and image quality, this classification method could be complemented.

Dental students' perceptions and educational impact of preclinical interactive videos compared and in combination with live demonstrations.

Objective: To study the utility of simulation videos with embedded quiz items compared and in combination with live hands-on demonstrations of dental procedures.

Methods: Thirty-three videos with embedded items were developed to help students understand the procedures they had to practice in the simulation laboratory. Videos were uploaded to the university LMS platform for students to watch and complete the embedded items as many times as they liked.

Contrasting student and staff perceptions of preclinical-to-clinical transition at a Chilean dental school.

Introduction: Dental education is a challenging and demanding field of study as students are expected to acquire various competencies to fulfil their professional requirements after graduation. The objective of this study was to investigate and compare dental students' and clinical staff instructors' perceptions of the preclinical-to-clinical transition training at a Dental School in Santiago, Chile.

Material And Methods: Two questionnaires containing 11 quantitative and one qualitative item were developed to assess our year three, four and five (n = 244) dental undergraduate students' challenges when they begin treating patients, and clinical staff (n = 78) perceptions of the preparedness to treat patients of the same students.

Students' and tutors' perceptions of a deliberate simulated practice using patient-specific virtual and three-dimensional printed teeth models: A pilot study.

Objective: This pilot study aimed to investigate the perceptions of dental students and their tutors of a deliberate simulated practice using patient-specific virtual and three-dimensional (3D) printed teeth models. This is before they perform their first indirect posterior tooth restoration on their patients.

Methods: Seventy-eight fourth-year dental students from the 2021 Comprehensive Clinic I course at the University of the Andes, Chile, were invited to participate in a deliberate practice protocol.
