Our previous studies have shown that pyrophosphate (PPi), the anticalculus component of tartar-control dentifrices, inhibits the growth of organisms associated with coronal and root surface caries. The purposes of this investigation were to: 1) determine if periodontal pathogens are similarly susceptible to the growth-inhibitory properties of PPi; and 2) determine if combinations of pyrophosphate-sodium dodecyl sulfate (PPi-SDS) inhibit growth synergistically. Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Fusobacterium nucleatum, Eikenella corrodens, and Campylobacter rectus (formerly Wolinella recta) were cultured in appropriate enriched media under anaerobic conditions. Inhibition assays were performed in tubes containing media supplemented with PPi and/or SDS. A range of concentrations of PPi and SDS in 2-fold increments was employed, with each concentration assayed in triplicate. Minimal inhibitory concentration (MIC) analyses revealed all of the bacteria were susceptible to PPi and SDS, with MICs of 0.67% (25 mM) and 0.01% w/v respectively. Combination studies with PPi-SDS showed much greater growth inhibition against P. gingivalis and A. actinomycetemcomitans than achieved with the agents individually. Determination of fractional inhibitory concentration indices indicated a synergistic growth-inhibitory effect. Under the constraints of the conditions employed, these studies demonstrate the efficacy of PPi-SDS combinations in inhibiting the growth of periodontal pathogens. It is conceivable that these compounds may have clinical benefit as a subgingival irrigant.
