IntroductionTo compare and evaluate clinically and radio-graphically the bone regeneration and the amount of bone fill in intrabony component of periodontal osseous defects through the osteoconductive and osteostimulative effect of bioactive synthetic NovaBone Putty - CMF and osteoconductive effect of calcified algae-derived porous hydroxyapatite Frios® Algi-pore® bone grafts.Materials and methodsTwenty-two sites in 11 patients, within the age range of 25 to 60 years, showing intrabony defects were selected according to split mouth design and divided into group I (Frios® Algipore®) and group II (NovaBone Putty - CMF). All the selected sites were assessed with the clinical and radiographic parameters like plaque index, gingival index (full mouth and site specific), sulcus bleeding index, probing pocket depth, clinical attachment level, gingival recession, and radiographic bone fill. All the clinical and radiographic parameter values obtained at different intervals (baseline, 3, and 6 months) were subjected to statistical analysis.ResultsA statistically significant reduction in pocket depth of 2.55 ± 0.52 mm (group I), 2.64 ± 0.67 mm (group II) and gain in clinical attachment level of 7.55 ± 1.44 mm (group I), 7.55 ± 2.38 mm (group II) were recorded at the end of the study. A slight increase in gingival recession was observed. The mean percentage change in amount of radiographic bone fill of group II (71.34%) was more than group I (61.93%).ConclusionBoth NovaBone Putty - CMF and Frios® Algipore® improve healing outcomes and lead to a reduction of probing depth, a resolution of osseous defects, and a gain in clinical attachment, but radiographic observation found better results with NovaBone Putty.How to cite this articleBembi NN, Bembi S, Mago J, Baweja GK, Baweja PS.

This study evaluated the ability of different adhesive materials in reducing the microleakage in class V amalgam restorations. Standardized class V cavities were prepared on the facial surface of 56 noncarious human premolars, they were then randomly divided into control and experimental groups based on adhesives used. Group I was the control group with Copal Varnish, group II had Panavia F 2.0, Group III contained Vitrebond Plus and group IV had RelyX ARC as adhesives. Amalgam was hand condensed into each preparation after application of adhesive material. Specimens were thermocycled, stained and sectioned. Microleakage was graded using a stereomicroscope. Less leakage was observed in all experimental groups compared to control group (p < 0.01) on nonparametric Kruskal-Wallis test. Mann-Whitney test observed leakage was more extensive at the gingival margins (p < 0.01) in all restorations than at occlusal margins. Group III showed no leakage which was significantly different from other groups (p < 0.05). Hence, this study concluded that application of intermediate adhesive material before condensation of amalgam can act as an effective barrier for microleakage.How to cite this article: Bembi S, Bembi NN, Sood A, Gambhir A.
