|Title:||Periodontal debridement with povidone-iodine in periodontal treatment: Short-term clinical and biochemical observations|
|Abstract:||Background: The aim of the present study was to evaluate the clinical effects of one-stage periodontal debridement with an ultrasonic instrument, associated with 0.5% povidone (pvp)-iodine irrigation in patients with chronic periodontitis. Methods: Forty-five patients were randomly assigned into three groups: the control group (CG) received quadrant root planing at I-week intervals over four consecutive sessions; the periodontal debridement plus pvp-iodine group (PD-PIG) received a 45-minute full-mouth debridement with an ultrasonic instrument, associated with 0.5% pvp-iodine irrigation; and the periodontal debridement group (PDG) received a 45-minute full-mouth periodontal debridement with an ultrasonic instrument, associated with NaCl irrigation. Results: At the 3-month evaluation, the mean probing depth (PD) reduction in CG was 2.51 +/- 0.52 mm, 2.53 +/- 0.50 mm in PD-PIG, and 2.58 +/- 0.60 mm in PDG (P < 0.05). The clinical attachment level (CAL) analysis showed a statistically significant gain in all groups compared to baseline (1.87 +/- 0.56 mm [CGI, 1.94 +/- 0.70 mm [PD-PIG], and 1.99 +/- 0.92 mm [PDG]). Intergroup analysis of PD and CAL at I and 3 months showed no differences (P > 0.05). The N-benzoyl-L-arginine-p-nitroanilide (BAPNA) test showed a significant reduction in trypsin activity only during the first month (P < 0.05); at 3 months there were no differences compared to baseline (P= 0.80). Conclusion: This study provides no evidence that pvp-iodine is effective as an adjunct for one-stage periodontal debridement.|
