ABSTRACT
The aim of the present study was to evaluate the prevalence of clinical and/or radiographic tooth resorption in a standardized population of 109 healthy cats fed dry diets, with specific emphasis on the mapping and typing of the lesions, as well as the influence of variables including breed, sex, and age. Prevalence of tooth resorption was significantly higher in pure-breed cats (70.0%) compared with mixed-breed cats (38.0%). A total of 290 tooth resorption lesions were diagnosed radiographically. For all lesions, 60.0% were Type 2 compared to 40.0% Type 1. There was an increased frequency of tooth resorption observed in older mixed breed-cats and female pure-breed cats. In conclusion, the current study demonstrated a strong breed influence (pure-breed vs. mixed-breed) on the prevalence of tooth resorption, as well as an uneven oral distribution with regard to mapping and typing characteristics.

Forty female Beagle dogs, aged 12 to 24-months were divided into four groups of ten dogs each. Results showed that increasing kibble diameter by 50.0% was associated with a 42.0% calculus reduction. Coating the kibbles with sodium tripolyphosphate, an anti-calculus agent, further induced a 55.0% calculus reduction. Sodium tripolyphosphate was shown to be at least as effective as sodium hexametaphosphate. The calculus reduction effect on teeth differed based on tooth location with the most pronounced effect being observed on caudally-located crushing teeth compared with incisor and canine teeth. The relevance of scoring non-crushing teeth when testing a product with mechanical effect on plaque and calculus needs to be questioned.
