The pH of the tooth surface was determined in cats with neck lesions. The presumption that commercial dry cat food with an acid coating can lead to neck lesions is investigated. In general cats with neck lesions had lower pH values of the tooth surface (7.93 +/-0.61) than healthy cats (8.65 +/- 0.58). Feeding dry cat food with an acid surface did not contribute to the pathogenesis of neck lesions.

Veterinary dental ultrasonic equipment can cause bacteria to be aerosolized during prophy procedures. Preoperative treatment with clindamycin prior to removal of calculus using an ultrasonic scaler can reduce aerosolized bacteria. Reduction of plaque bacteria was assessed and was statistically significant in those patients receiving clindamycin. This article describes the evaluation and results of clindamycin application when given prior to dental prophy.
