Development of a teaching model for coronal access to the canine dentition.
A dolichocephalic canine skull was utilized to develop a teaching and study model for coronal access cavity preparation of the dentition. The teeth from the right side of the skull were extracted. Each tooth was radiographed in two planes to localize the "ideal" endodontic access point. Barium markers were placed over these points and each tooth was radiographed again to confirm the appropriate location of the marker. Access was created by drilling through the barium marker. Then, K-files were inserted through the access preparation into the root canal system. The teeth were radiographed with the K-files in place to verify straight pathways to the apices. Straight line access to the apex was obtained in all teeth. Creation of this model provides an opportunity for the veterinary dental student to develop and refine skills used in performing endodontic therapy. The model can be utilized by the veterinary dental practitioner in clinical practice.
