Abstract

A need for more realistic tooth models for education has often been expressed by dental students. The aim of this study was to design and create 3D printed teeth with anatomical details for use in preclinical dental education. A tooth with realistic carious lesions and pulp cavity was designed, and this tooth was used in 2018 with 47 dental students for preclinical education in caries excavation, direct capping of the pulp, core build-up, and crown preparation. The students had the ability to identify the carious lesions by a simulated radiograph and by tactile sense of the consistency. The benefits of the 3D printed tooth were evaluated by a questionnaire. The printed tooth was evaluated by grades (1=excellent, 2=good, 3=satisfactory, 4=adequate, 5=poor). The students gave the tooth an overall mean grade of 1.9, with a grade of 2.0 for the haptic impression, 1.5 for the exercise, 1.9 for the examination, and 1.5 for high practical relevance in contrast to a standard model tooth. The new features of the printed tooth were given a mean grade of 2.0 for the radiograph, 2.3 for consistency of the caries, 2.0 for the tooth filling, and 1.7 for the pulp capping as realistic. The students had the possibility to generate a complete concept for prosthodontic tooth treatment on an artificial 3D printed tooth.
