Povidone-iodine gel and solution as adjunct to ultrasonic debridement in nonsurgical periodontitis treatment: an RCT pilot study


Sahrmann, Philipp; Imfeld, Thomas; Ronay, Valerie; Attin, Thomas; Schmidlin, Patrick R (2014). Povidone-iodine gel and solution as adjunct to ultrasonic debridement in nonsurgical periodontitis treatment: an RCT pilot study. Quintessence International, 45(4):281-290.

Abstract

OBJECTIVES: Polyvinylpyrrolidone-iodine (PVP-iodine or povidone- iodine) enhances the treatment outcomes of initial periodontal treatment but the degree of benefit varies in the literature. A main reason might be the concentration of the dosage form and its contact time with the periodontal tissues. In this randomized pilot study the effect of repeated subgingival application of PVP-iodine during scaling and root planing (SRP) was assessed. Changes of clinical parameters and microbiotic taxa after 3 months were analyzed.
METHOD AND MATERIALS: In a split-mouth design 12 patients with generalized, severe periodontitis were treated with SRP combined with subgingival application of either PVP-iodine or water. Test and control sides were isolated with a special rubber dam technique. Irrigations were reapplied during SRP. Periodontal probing depth (PD) and recessions were documented before treatment and after 3 months. Samples of subgingival bacteria before SRP and after 1 week, 1 month, and 3 months were analyzed.
RESULTS: Three months after SRP, changes for PD and recession in deep pockets were significantly higher in the PVP-iodine group (P = .012 and .044 respectively). The number of these pockets was reduced from 73 at baseline to 8 in the test and 19 in the control group. In both groups, bacterial taxa were reduced after 1 week. One month after SRP only taxa of Porphyromonas gingivalis in the PVP-iodine group were lower than at baseline. After 3 months, all taxa regained baseline values.
CONCLUSION: PVP-iodine reapplied frequently during SRP might enhance pocket depth reduction in initially deep pockets.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
