Background: Improvements of the substantivity of antibacterial agents in periodontal pockets during active therapy is still a challenge. With this study, the release kinetics of PVP-iodine by simply creating mixtures of a PVP-iodine solution and powder incorporated in different concentrations into a commercially available wound paste was investigated. It was postulated that this approach could result in an extended iodine release of at least one hour resulting in adequate antibacterial concentrations. Methods: Iodine concentrations released by different formulations were determined by a titration method and the antibacterial effect was investigated using an agar diffusion method assessing the inhibition zone of two representative periopathogenic bacteria (Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis) . Results: A prolonged release kinetic with up to one third of iodine released after one hour and even an ongoing release up to 4 hours was shown. The cumulative concentrations in the immersion solutions were sufficiently high to effectively inhibit bacterial growth in the agar test. The pH of the different mixtures was adequately buffered when tested in SBF as immersion medium, but resulted in acidic conditions when water was used. Conclusions: Simple mixing of PVP-powder to an available wound paste may offer an easy method to prepare antibacterial products in-office with a potential pocket disinfection duration during the scaling and root planning appointment. Nevertheless, its therapeutic usefulness under clinical conditions needs further investigation and potential side-effects require clarification.

The aim of this study is to examine the effect of different finishing and polishing systems on the surface roughness, microhardness and microleakage of a nano-hybrid composite. The effect of four different finishing and polishing systems (Mylar-strip, Diamond finishing bur, Sof-lex disc, PoGo) were evaluated on a nanohybrid composite (Ceram-X mono, Denstply). The surface roughness was measured by profilometer, microhardness was measured by Vicker's icrohardness tester. For microleakage evaluation, class V cavities (3x4x2 mm) were prepared at cemento-enamel junction of 60 third molars. Teeth were thermocycled 500 times (5-55°C) and immersed in 0.5% basic-fuchsin for 24-hours and evaluated. The two-way ANOVA and Posthoc tests were used for surface roughness, One-way-variance-analysis and Posthoc tests were used for microhardness and microleakage was analyzed by Kruskal-Wallis and Mann-Whitney-U tests. Measured surface roughness scores listed according to the techniques as; PoGo＜Mylarstrip= Sof-lex＜Diamond bur (p=0.000), microhardness scores as; Mylar-strip=diamond bur＜Sof- Lex＜PoGo (p=0.010), microleakage scores as; PoGo＜diamond bur=Mylar-strip＜Sof-Lex (p=0.004). PoGo was found as the most successful group regarding the investigated properties. Conclusions: The findings revealed that finishing and polishing techniques have a significant effect on the surface roughness, surface hardness and marginal sealing ability of composite restorations.
