title: The comparative efficacy of two commercial tartar control dentifrices in preventing calculus development and facilitating easier dental cleanings.
abstract: Tartar control dentifrices have been proven effective in reducing the build-up of supragingival calculus deposits between professional tooth cleanings. In addition to providing consumers with a cleaner dentition, these formulations can, in principle, contribute to easier professional tooth cleaning. Until recently, clinical methods for evaluating the effects of tartar control dentifrices were limited to the assessment of area coverage of calculus on the tooth surface. The development of the Quanticalc dental scaler permits the quantitative clinical measurement of force and stroke number associated with supragingival calculus debridement. In this clinical study, two commercial tartar control dentifrices, one containing 5.0% pyrophosphate as the tartar control agent and the other containing a combination of 1.3% pyrophosphate and 1.5% Gantrez copolymer, were compared for efficacy in reducing the development of supragingival calculus between prophylaxes, and in facilitating easier calculus removal in subsequent scaling. Results showed that the two commercial dentifrices were equally effective in reducing calculus extent between prophylaxes. In contrast, the 5.0% pyrophosphate dentifrice was observed to be almost twice as effective on a percentage basis as the lower dosage pyrophosphate dentifrice in facilitating easier calculus removal. The enhanced activity of the 5.0% pyrophosphate dentifrice may be postulated to be due to elevated dosage of tartar control crystallization inhibitor or to potential side effects of copolymer in the other commercial dentifrice. Importantly, these results substantiate that the clinical benefits of tartar control dentifrices are not completely described by actions in reducing calculus build-up as assessed by VMI, and that important clinical benefits and differences in efficacy may be provided by these formulations in facilitating easier dental cleaning of supragingival calculus.
