Concordance of judgement: A tool to foster the development of professionalism in dentistry.

INTRODUCTION: Developing professionalism notably involves learning how to make professional judgements in ambiguous situations. The Concordance of Judgement Test (CJT) is a learning tool that was proposed to develop professionalism competencies, but it was never performed in dentistry or used with a synchronous methodology. The present study evaluated the feasibility of the use of CJT in the context of dental education, to foster professionalism and stimulate reflexivity and discussion. MATERIALS AND METHODS: After different steps of optimization, a questionnaire presenting 12 vignettes was submitted to 33 Canadian students. Second, after an additional optimization, a questionnaire of 7 vignettes was submitted to 87 French students. An immediate educational feedback was proposed after each vignette to promote reflexivity and discussions during the experience. RESULTS: The overall experience of the students was reported as good, thanks to the feedback of real-life situations. This promoted reflexivity and stimulated discussion between students and educators regarding professionalism issues. The students considered CJT as a relevant and well-adapted tool, and reported positive feelings regarding the inter-university aspect of the activity. The mean score of the panel members was close to 80/100 and the mean score of the students was 5 to 10 points lower, which is in agreement with docimological performance. CONCLUSION: The results suggested that the use of CJT in a synchronous way was a feasible and relevant tool to motivate the students to improve their professionalism, and to stimulate their reflexivity and discussion. The students reported positive experience with CJT, and we believe that this tool can be integrated in the dental curriculum.

Improving digital scans by using a peripheral custom tray: A dental technique.

A digital dental technique is described for registering functional borders of immediate complete dentures, by using an intraoral scanner, a dental computer-aided design software program, and a peripheral custom tray. This article also illustrates how to virtually match the recorded information in order to transform the initial intraoral scan into definitive digital scans.

Digital prosthodontic management of a young patient with Papillon-Lefèvre syndrome: A clinical report.

Papillon-Lefèvre syndrome (PLS) is a rare disorder that leads to symptoms including the early progressive loss of deciduous and permanent teeth. Prosthodontic management of children and adolescents affected by PLS sometimes requires an immediate complete denture. Tooth mobility presents a challenge to the dentist, especially during impression-making. This clinical report describes the management of a 14-year-old boy with PLS by using an intraoral scanner to prevent conventional impressions and a fully digital workflow for the design and fabrication of immediate complete dentures.

CAD-CAM immediate to definitive complete denture transition: A digital dental technique.

The present article describes a digital workflow for the fabrication of definitive complete dentures in 2 appointments by reproducing the cameo surface and tooth arrangement of computer-aided design and computer-aided manufacturing (CAD-CAM) immediate dentures. This straightforward technique, which requires limited time and effort, can be easily applied by using an intraoral scanner, a dental CAD software program, and a milling machine.

Manufacturing of an immediate removable partial denture with an intraoral scanner and CAD-CAM technology: a case report.

BACKGROUND: Incisor loss constitutes a strong aesthetic and psychologic traumatism for the patient and it remains a challenging situation for the dental practitioner because of the necessity to rapidly replace the lacking tooth. Various therapeutic procedures have been proposed to replace the incisor concerned, for example by using a removable partial denture. However, the manufacturing of such a denture with classical procedures is often subject to processing errors and inaccuracies. The computer-aided design and computer-aided manufacturing (CAD-CAM) technology could represent a good alternative, but it is currently difficult because of the lack of dental softwares able to design easily immediate removable partial dentures. CASE PRESENTATION: A 30-year- patient complained about pain caused by a horizontally and vertically mobile maxillary right central incisor. After all options were presented, extraction of the traumatized incisor was decided due to its very poor prognosis, and the patient selected the realization of a removable denture for economic reasons. The present paper proposes an innovative procedure for immediate removable denture, based on the use of an intraoral scanner, CAD with two different softwares used sequentially, and CAM with a 5-axis machine. CONCLUSIONS: We show in this report that associating an intraoral scanner and CAD-CAM technology can be extended to immediate dentures manufacturing, which could be a valuable procedure for dental practitioners and laboratories, and also for patients.

Immersive 3D Educational Contents: A Technical Note for Dental Educators.

Three-dimensional files featuring patients' geometry can be obtained through common tools in dental practice, such as an intraoral scanner (IOS) or Cone Beam Computed Tomography (CBCT). The use of 3D files in medical education is promoted, but only few methodologies were reported due to the lack of ease to use and accessible protocols for educators. The aim of this work was to present innovative and accessible methodologies to create 3D files in dental education. The first step requires the definition of the educational outcomes and the situations of interest. The second step relies on the use of IOS and CBCT to digitize the content. The last "post-treatment" steps involve free software for analysis of quality, re-meshing and simplifying the file in accordance with the desired educational activity. Several examples of educational activities using 3D files are illustrated in dental education and discussed. Three-dimensional files open up many accessible applications for a dental educator, but further investigations are required to develop collaborative tools and prevent educational inequalities between establishments.

Monolithic CAD/CAM Complete Overdentures for a Pedodontic Patient with Dentinogenesis Imperfecta and Limited Prosthetic Space: A Clinical Report.

Children affected by dentinogenesis imperfecta (DI) require restorative techniques or prosthodontic management to minimize the functional and psychosocial impacts of the condition. In cases of excessive wear of the deciduous dentition and moderate cooperation from the child, removable complete overdenture prostheses are the most suitable treatment option. However, limited restorative space is a technical challenge for the placement of such prostheses. Advances in digital technologies can help assist in the fabrication of monolithic prostheses with reduced thickness. The present clinical report describes the management of a moderately cooperative 7-year-old patient suffering from DI with severe tooth wear, reduced restorative space, and a high smile line. The design and fabrication of complete overdentures were performed using a digital workflow. This innovative monochromatic monolithic approach combined with the use of gingiva-shade composite resin respected the available restorative space while obtaining a natural esthetic appearance. Such a strategy requires regular denture replacement according to the child's growth and loss of deciduous dentition. An additional aim is to obtain the cooperation needed for a future global fixed rehabilitation over time.
