Non-surgical instrumentation associated with povidone-iodine in the treatment of interproximal furcation involvements

Abstract

ObjectiveThe aim of this controlled clinical trial was to evaluate the effect of topically applied povidone-iodine (PVP-I) used as an adjunct to non-surgical treatment of interproximal class II furcation involvements. Material and methodsThirty-two patients presenting at least one interproximal class II furcation involvement that bled on probing with probing pocket depth (PPD) ≥5 mm were recruited. Patients were randomly chosen to receive either subgingival instrumentation with an ultrasonic device using PVP-I (10%) as the cooling liquid (test group) or identical treatment using distilled water as the cooling liquid (control group). The following clinical outcomes were evaluated: visible plaque index, bleeding on probing (BOP), position of the gingival margin, relative attachment level (RAL), PPD and relative horizontal attachment level (RHAL). BAPNA (N-benzoyl-Larginine-p-nitroanilide) testing was used to analyze trypsin-like activity in dental biofilm. All parameters were evaluated at baseline and 1, 3 and 6 months after non-surgical subgingival instrumentation. ResultsSix months after treatment, both groups had similar means of PPD reduction, RAL and RHAL gain (p>0.05). These variables were, respectively, 2.20±1.10 mm, 1.27±1.02 mm and 1.33±0.85 mm in the control group and 2.67±1.21 mm, 1.50±1.09 mm and 1.56±0.93 mm in the test group. No difference was observed between groups at none of the posttreatment periods, regarding the number of sites showing clinical attachment gain ≥2 mm. However, at 6 months posttreatment, the test group presented fewer sites with PPD ≥5 mm than the control group. Also at 6 months the test group had lower BAPNA values than control group. ConclusionThe use of PVP-I as an adjunct in the non-surgical treatment of interproximal class II furcation involvements provided limited additional clinical benefits.

Surgical and nonsurgical periodontal therapy. Learned and unlearned concepts

“…Antiseptics, including povidone‐iodine, dilute sodium hypochlorite and chlorhexidine gluconate, have been used for periodontal pocket irrigation following debridement with the aim of suppressing the biofilm. Some studies have shown further reduction in periodontal pathogens and probing depths compared with scaling and root planing alone (95, 97, 102, 103). As gingival crevicular fluid within a periodontal pocket is replaced every 90 s, the effects of antiseptic pocket irrigation are only transient and the risks of antiseptics penetrating the gingival tissue and causing systemic effects are minimized.…”

Low‐cost periodontal therapy

“…Povidone‐iodine kills all major periodontopathic bacteria in vitro within 15–30 s (210, 291), and exhibits a wide virucidal spectrum, covering both nonenveloped and enveloped viruses (163), including the periodontopathic cytomegalovirus (216). Studies have shown a measurable improvement in the periodontal status after treatment with povidone‐iodine (240, 258, 278). Huong et al.…”
