Title: Correlations between salivary protease and supragingival or subgingival calculus index. Author: Watanabe T, Toda K, Morishita M, Iwamoto Y. Journal: J Dent Res; 1982 Sep; 61(9):1048-51. PubMed ID: 6763041. Abstract: Significant positive correlations between protease activities in saliva and supragingival/subgingival calculus indices, periodontal pocket depth, or P-M-A index were confirmed. When the partial correlation was calculated, the subgingival calculus index correlated well with the sediment protease at pH 8.5, and the supragingival calculus index showed a significant correlation with the supernate protease at pH 4.5.[Abstract] [Full Text] [Related] [New Search]
