Utility of three-dimensional-printed tooth model for training purpose of apical barrier placement technique

ABSTRACT Aim: The application of three-dimensional (3D) printing in dentistry is becoming increasingly valuable from clinical dentistry to student training, teaching, and simulation training. Mastering 3D-printed models’ usage is essential for general dental practitioners (GDPs) as it allows them to choose and necessarily know what is offered, as well as how to implement it in everyday practices, thereby contributing to the betterment of the dental profession. The study aims to assess and quantify GDPs knowledge, understanding, and practices related to the use of 3D-printed tooth model for apical barrier placement technique. Methodology: A cross-sectional study was conducted in the form of self-explanatory questionnaire in the form of 18 questions that evaluated their knowledge and awareness regarding 3D printing. The sample size of 94 GDPs was asked to respond to questionnaire. After the workshop, GDPs were questioned regarding their satisfaction with the simulation of the apical barrier technique with a 3D model. Responses were structured by a five-point Likert scale (1, strongly disagree; 2, disagree; 3, neither agree nor disagree; 4, agree; and 5, strongly agree). Results: A total of 94 replies were obtained after the questionnaire was circulated. Awareness regarding the apical barrier placement technique in open apex cases was known by 61% of practitioners before the workshop. Most of the GDPs strongly agreed with the skill acquisition on a 3D open apex tooth model after the training workshop and it met their expectations. Conclusions: 3D modeling of open apex cases with the application of apical barrier placement technique is useful to give a simulation experience to GDPs. However, with consideration of costs and long processing times, 3D printing may be used optimally for technique-sensitive cases.
