Tooth resorption and vitamin D3 status in cats fed premium dry diets.

Abstract
It has been suggested that tooth resorption (TR) in cats is associated with vitamin D3 status. The purpose of this study was to evaluate any correlation between serum 25-OH-D concentrations and the prevalence of TR. The healthy adult domestic cats (n=64) of this study had been fed similar premium dry-expanded foods throughout their lives. Serum 25-OH-D was measured, and cats received a single, complete periodontal examination, with periodontal probing of each tooth and exploration of the tooth surface using a dental explorer A complete set of 10 dental radiographs was taken for each cat. There were 168 TRs diagnosed in 40 of 64 cats (85 were Type 1 TR and 83 were Type 2). The mean serum 25-OH-D concentration was 187.7 +/- 87.3 nmol/L. The mean serum 25-OH-D in cats with one or more TR was 164.2 +/- 78.8 nmol/L, compared with 226.8 +/- 88.2 nmol/L for those without TR (p = 0.14). The mean serum 25-OH-D in the 13 cats with >5 TR was 131.2 +/- 49.5 nmol/L, which was significantly less than in cats with no TR (p < 0.05). There was no relationship between TR type and serum 25-OH-D. There was no effect of age or sex on serum 25-OH-D. On the contrary, variations in serum 25-OH-D were observed according to the studied breeds. There was no relationship between TR type and serum 25-OH-D. TR prevalence was greater in cats with lower serum 25-OH-D concentrations. In conclusion, the hypothesis that higher serum 25-OH-D concentrations are associated with a higher prevalence of TR is not supported by this study.
