Summary
Idiopathic dental root replacement resorption was observed in six older large dogs. This condition involves abnormal root reshaping and resorption, similar to a human dental issue.
Area of Science:
- Veterinary Dentistry
- Comparative Pathology
Background:
- Root resorption is a pathological process affecting teeth.
- Idiopathic dental root replacement resorption (IDRR) is recognized in human dentistry.
- The prevalence and characteristics of IDRR in large-breed senior dogs are not well-documented.
Purpose of the Study:
- To investigate the occurrence and radiographic and histologic features of root resorption in aged large-breed dogs.
- To compare findings in dogs with those of idiopathic dental root replacement resorption in humans.
Main Methods:
- Radiographic examination of teeth from 33 euthanized large dogs (≥10 years old).
- Exclusion of dogs with clinical signs or macroscopic evidence of oral disease.
- Histological examination of teeth with radiographic abnormalities.
Main Results:
- Six of 33 dogs (18.2%) exhibited abnormally shaped and partially resorbed tooth roots.
- Radiographs showed replacement of root structure by normal-appearing trabecular bone.
- Histology confirmed mid-root resorption without inflammation or hypercementosis.
Conclusions:
- A condition resembling idiopathic dental root replacement resorption occurs in aged large-breed dogs.
- This finding suggests a potential comparative model for studying root resorption.
- Further research into the etiologies of this condition in dogs is warranted.
