Oral health assessment in dogs: study design and results.
The authors have conducted a large number of canine dental studies during the past six years. Study methodologies have been driven by the need for statistical validation of results, requiring the participation of large numbers of animals in each study. For plaque, stain, and calculus evaluations, a "clean tooth" model was used, in which formation of these substrates was assessed days to weeks after an initial coronal cleaning. A primary goal of the studies described was to validate the study designs used--that is, to use accepted plaque-, calculus-, and stain-controlling agents to test whether the study methods could detect differences between treated and untreated groups. The results of clinical studies show that the methods described can be used to identify plaque, calculus, and stain control attributable to chemical agents, oral hygiene aids, and consumable products.
