Forty mixed-breed cats completed a parallel-group, clinical study to compare supragingival plaque accumulation using a triangular or rectangular shaped dry-expanded diet, with or without an anti-calculus agent (sodium tripolyphosphate) or an anti-plaque agent (plaquereducing nutrient). The cats were divided into 4 equal groups based on plaque scores. Results showed that coating the kibble with sodium tripolyphosphate had no effect on plaque accumulation. Increasing the surface area and volume and changing the shape of the kibble was associated with a reduction in plaque accumulation, and coating the kibble with a plaque-reducing nutrient further reduced plaque accumulation. The importance of a combination of both mechanical abrasion (chewing) and chemical interference (plaque-reducing nutrient) was demonstrated in this study.
