Three-Dimensional tooth models for better teaching and treatment outcomes.

Abstract

The aim of this study was to fabricate 3-Dimensional (3D) tooth models to overcome procedural errors that occur during treatment and to improve endodontic management of teeth with complex pulp morphology and dental anomalies. Three natural teeth were used to fabricate resinous tooth models (n=90) and 90 natural teeth were used during root canal treatment. Models were fabricated from 1 mandibular canine (n=30) and 2 maxillary molars (n=60). Natural teeth were 30 mandibular canines, 30 mandibular molars and 30 maxillary molars. Natural teeth and opaque resin models were significantly better than the clear resin models during access preparation (p=.003). In addition, the clear resin models were significantly better than the natural teeth and opaque resin models during shaping, obturation and as an educational tool (p < .001, p < .001 and p < .001 respectively). Although it takes more time and effort to produce 3D (3D) tooth models from each natural tooth used in the study, it can give more accurate results during evaluation.
