Methods: In this historical cohort study 40 volunteers were divided into two groups based on their PSA levels. Group I had PSA level≤4 ng/dl and group II≥4 ng/dl. Plaque and gingival index, probing depth and clinical attachment level (CAL) were determined. Statistical analysis between the two groups was done using Leven and independent T test.
Results: There was statistically significant difference in PSA levels between the two groups. Also, all the periodontal parameters had higher value for the group with PSA level≥4 ng/dl and the differences were significant (P<0.001).
Conclusions: Subjects with more severe periodontitis had higher PSA level. Periodontal conditions may be considered as a factor in increasing the serum PSA level.
