Introduction:
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.
Materials And Methods:
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.
Results:
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).
Conclusions:
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.
