Abstract: Objective:To evaluate the usefulness of Periocheck in clinical application before and after periodontal curettage.Methods:Periocheck was applied in 65 sites in 65 adult patients with periodontitis within 15 min before and after scaling and root planing to monitor peptidase activity produced by Porphyromones gingivalis (Pg),Treponema denticola(Td) and Bacterides forsythus (Bf) in subgingival plaque. The peptidase activity was determined both spectrophotometrically and by using color standard.Results:The peptidase concentrations (Try U/L) before and after treatment were 0.44±0.23 and 0.34±0.26 (P<0.05),while Periocheck positiveness was found in 65/65 and 43/65 (P<0.01) of the patients,respectively.After treatment clinical parameters such as GI, PD,AL and peptidase concentration decreased (P<0.05) in 22 Periocheck positive patients,while those did not (P>0.05) in 43 negitive.Conclusion:Periocheck might provide a promising chair-side monitoring tool for the evaluation of scaling and root planing.
