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.
使用一个长头型犬类头骨来开发一个用于牙列冠状入路腔制备的教学和研究模型。提取了头骨右侧的牙齿。每颗牙齿在两个平面上进行放射照相，以定位“理想”的根管治疗入路点。在这些点上放置钡标记物，然后对每颗牙齿再次进行放射照相，以确认标记物的合适位置。通过钻穿钡标记物来创建入路。然后，将K锉通过入路制备插入根管系统。在K锉就位的情况下对牙齿进行放射照相，以验证通向根尖的直线通路。所有牙齿均获得了通向根尖的直线入路。这个模型的创建为兽医牙科学生提供了一个发展和完善进行根管治疗所使用技能的机会。该模型可供兽医牙科从业者在临床实践中使用。
