Correlation between calculus index and acid and alkaline pyrophosphatases activities of dental plaque and saliva.
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.
