Summary
Packing dentin chips into the apical opening of cat canine teeth promoted faster root canal healing. This method resulted in less inflammation and more cementum deposition compared to teeth without dentin plugs.
Area of Science:
- Veterinary Dentistry
- Endodontics
- Comparative Anatomy
Background:
- Vital maxillary canines in mature cats were used as a model.
- Intentional instrumentation through the apical foramen was performed.
Purpose of the Study:
- To evaluate the effect of dentin chip packing on root canal healing.
- To compare healing in teeth with and without apical dentin plugs.
Main Methods:
- No. 50 K-files were used for canal instrumentation.
- Dentin chips were packed into the apical opening of one canine per animal.
- Contralateral canines served as controls without dentin plugs.
- Both canals were obturated with gutta-percha.
- Animals were euthanized at 3, 5, and 8 months for analysis.
Main Results:
- Specimens with packed dentin fillings exhibited quicker healing.
- Minimal inflammation was observed in teeth with dentin plugs.
- Increased cementum deposition was noted where dentin fillings were present.
Conclusions:
- Apical packing of dentin chips enhances root canal healing in feline teeth.
- This technique may reduce inflammation and promote cementum repair post-endodontic treatment.
