Abstract:
Experiments were performed to determine if a pyrophosphate-containing anticalculus toothpaste could affect certain salivary constituents involved in the mineralization of dental plaque. The findings indicated no obvious changes in acid and alkaline pyrophosphatases, ionized calcium, total calcium, inorganic phosphate or pH in saliva for 1-135 min after brushing the teeth with the anticalculus toothpaste. Data obtained by brushing with the toothpaste three times daily for two weeks also confirmed these results. Our findings clearly indicate that pyrophosphate-stabilizing agents in the anticalculus toothpaste are not fully effective in the oral cavity. In addition, the pyrophosphate-containing toothpaste has no influence on the state of calcium and phosphate in saliva.
