Development of a teaching model for coronal access to the canine dentition

Area of Science:

• Veterinary Dentistry
• Endodontics
• Comparative Anatomy

Background:

• Coronal access cavity preparation is a critical step in endodontic therapy.
• Developing effective teaching models is essential for veterinary dental education.
• Standardized methods for demonstrating straight-line access are needed.

Purpose of the Study:

• To develop and evaluate a reproducible teaching model for coronal access cavity preparation in veterinary dentistry.
• To demonstrate a method for achieving straight-line access to the root canal system using a canine skull model.

Main Methods:

• A dolichocephalic canine skull was used, with teeth extracted from one side.
• Radiographs were taken to identify the ideal endodontic access point on each tooth.
• Barium markers were placed at identified points, followed by radiography for confirmation.
• Access cavities were prepared through the markers, and K-files were inserted into the root canals.
• Post-preparation radiography confirmed the pathway of K-files to the root apex.

Main Results:

• The developed model facilitated the preparation of coronal access cavities.
• Radiographic verification confirmed that straight-line access to the root canal apex was achieved in all prepared teeth.
• The technique proved effective in establishing clear pathways to the apical region.

Conclusions:

• This canine skull model provides a valuable tool for veterinary dental students to learn and practice coronal access cavity preparation.
• The model aids in refining the skills necessary for successful endodontic treatment in veterinary practice.
• The method ensures reproducible straight-line access, a key factor in endodontic success.
