It is notinfrequent that patients have their teeth sealed and polishedand consequently have the salivary deposits entirely removed,while the subgingival deposits remain untouched. In this wayAve may in part account for the fact that in a number of in-stances the subgingival deposit is found while the salivary is notto be seen.
