title: Correlation between calculus index and acid and alkaline pyrophosphatases activities of dental plaque and saliva.
abstract: The activities of acid and alkaline pyrophosphatases were measured in human plaque of thirty subjects and saliva of twenty-two subjects. A study of correlation and analysis of variance were done between the pyrophosphatasic activity and the calculus index. A significant positive relationship has been established.
