Tooth resorption Flashcards
(2 cards)
What are the two types of tooth resorption
Type 1 lesion (inflammatory)
- inflammatory root resorption
- the alveolar bone adjacent to the tooth defect is also resorbed
- mandibular third premolar and molar teeth are most commonly affected
Type 2 lesion (non-inflammatory)
- narrowing of the periodontal space may result in ankylotic fusion (dentoalveolar ankylosis) between the tooth and alveolar bone
- ankylosed roots are at risk of being incorporated into the normal bone remodeling process, resulting in gradual resorption of the root and replacement by bone
- canine teeth are more likely to have type 2 lesions
What could be an etiological explanation for tooth resorption in cats
Cats with tooth resorption were shown to have significantly lower USG and significantly higher serum concentration of vitamin D, compare to cats without tooth resorption
- commercial cat foods often contain vitamin D in excess of the maximal allowance
- since a direct linear relationship exists between 25OHD serum concentrations and dietary intake of vitamin D, cats with higher 25OHD serum concentrations must have ingested larger amount of vitamin D orvitamin D metabolites
- decreased USG could be associated with abnormal mineralization of kidneys due to excessive dietary intake of vitamin D
