Historically, the fabrication of a provisional post, core, and crown for endodontically-treated teeth was taught during one-on-one teaching sessions in the presence of a patient in the dental clinic. This method of instruction required a lot of valuable clinic time, and resulted in variability among student performance. To address this we created a preclinical laboratory session for fabricating a provisional restoration for an endodontically treated anterior tooth with a treatment plan to receive a cast post and core restoration, as well as a standardized rubric for evaluation. Methods: The 3-hour lab session begins with a 35− to 45-minute presentation of the acceptable clinical technique and alternate materials that can be used. A 10-question quiz is included to check student understanding. The students then have 1-hour to practice the technique following a step-by-step manual and their fabrications are evaluated using a standard rubric. The students then come together for a presentation on their combined evaluations in order to discuss common errors, their causes, and how they can be avoided. Results: In 2015, 83 University of Florida College of Dentistry dental students participated in this lab. Upon reviewing the rubrics, about 65% of the class made no errors, and 20% of the class made two or three errors. The most common error was poor finish and polish and was observed with 18 students. The least common error was post head showing facially and was observed with three students. Discussion: While results were only for one cohort, the students demonstrated a good understanding of the technique after this lab session. Future studies with additional cohorts should be reported and analyzed. ---------------------- Educational Objectives By the end of this session, facilitators will be able to: Detail the steps for fabricating a provisional restoration for an endodontically-treated tooth. Describe the current technology for fabricating a vaccuform matrix and a variety of provisional restorations. Critically evaluate a fabrication of a provisional post, core, and crown for endodontically-treated teeth. Analyze a provisional post, core, and crown fabrication for the most common errors and describe how to avoid them. --------------------- Includes instructor guide and Powerpoint
