Search for: [Abstract = "t questionnaire. In Publication No 3 \- extracted incisors, premolars, and molars were imaged with the aid of a CBCT. The collected data were subsequently analysed in the Model Creator \(Exocad, Germany\) program for creating visualisations of 3D models. The 3D teeth models were made from Dental Model resin with the aid of a 3D Form 2 printer \(Formlabs, USA\), using SLA technology. Ninety teeth models were printed out, i.e. 30 molars, 30 premolars, and 30 incisors. Then, the teeth were randomly divided into 9 groups. One fourth\-year dental student with no experience in root canal treatment was randomly assigned to each group. A dental specialist demonstrated a proper opening of the pulp cavity to the students, and then each student carried out a primary cavity access procedure in 10 identical 3D models. The actual correctness of the implemented procedures was assessed under a microscope, whereas all additional assessments and measurements were pursued in full conformity with the images supplied by a millimetre\-scale camera, and with the aid of a scanner. RESULTS The scoping review \(Publication No 1\) indicated that 3D\-printed teeth models, as originally developed for teaching purposes, had already been in use in various areas of dentistry. Their general assessment and usefulness in acquiring pertinent hands\-on skills for clinical work was favourably rated in all studies, regard"]
