RESUMEN
Objective and Background: Povidone-iodine might constitute a valuable adjunct to current periodontal therapy because of its broad-spectrum antimicrobial activity, low potential for developing resistance and adverse reactions, wide availability, ease of use, and low financial cost.The present study was performed to assess the clinical outcome of irrigation using 10% Povidone Iodine in periodontitis patients.Material and Methods: 10 patients (age range 35-65 years) with moderate to severe periodontitis on the basis of clinical parameters were selected.4 quadrants were randomly divided according to mode of treatment- 1st quadrant- scaling and root planing + subgingival irrigation with 10% Povidone iodine, 2ndquadrant - scaling and root planing, 3rd quadrant -subgingival irrigation with 10% Povidone iodine. 4th quadrant - no treatment, The Clinical variables were determined at baseline and 4 weeks post- treatment Results: The results showed a mean reduction of pocket depth of 1.98mm, change in the plaque index and gingival index from 2.22±0.3 to 1.22 ±0.2 and 2.2 ±0.2 to 1.1±0.4 respectively in the group treated with povidone iodine along with scaling and root planing which was highly significant. Conclusion: This study demonstrates positive effect of the subgingival irrigations with 10% povidone iodine in cases of severe chronic periodontitis. However, subgingival irrigation with PVP-iodine without concomitant mechanical debridement might not vary clinical variables.
RESUMEN
Objective:To assess the clinical and microbiologic effects of ultrasonic scaling with simultanous irrigation with chlorhexidine(CHX), conventional ultrasonic scaling or subgingival irrigation. Methods: 20 teeth in 7 patients with periodontitis were equally divided into test and control group. Patients in the test group were treated by irrigation with CHX during ultrasonic scaling(Master400),those in the control with irrigating after scaling(MiNi ). Clinical assessments of bleeding on probing (BOP),probing depth (PD) were made just before and 7 and 14 days after treatment. The subgingival microbiologic examination was performed before and 0,7 and 14 days after treatment. Result: Significant reductions in PD and BOP were observed in both groups 7 and 14 days after treatment(P
