The vertical and horizontal dimensions of interproximal areas had a substantial, independent, and combined effect on the existence of interproximal papillae.

Background:The synthetic anorganic bone matrix/cell-binding peptide (ABM/P-15) has displayed an increased fibroblast migration and attachment with bone graft material, thus enhancing periodontal regeneration. The objective of the present study was to evaluate and to correlate the efficacy of open flap debridement (OFD) with and without ABM/P-15 in the treatment of human infrabony periodontal defects.Materials and Methods:A total of 20 chronic periodontitis patients with equal number infrabony defects were randomly selected and assigned into two groups depending on the treatment received: Control group (treated with OFD) and Test group (treated with OFD + ABM/P-15). Clinical parameters recorded included plaque index, gingival index, probing pocket depth (PPD), clinical attachment level (CAL), gingival recession, and radiographic defect depth (RDD) which were evaluated at baseline and 6 months postsurgically.Results:When compared to baseline, both the treatment groups demonstrated improvements in the clinical parameters at 6 months. Test group exhibited a mean PPD reduction of 4.15 ± 1.04 mm, CAL gain of 3.10 ± 1.42 mm, and reduction in RDD of 1.90 ± 0.72 mm postoperatively at 6 months. In contrast to Control group, the Test group showed greater reduction in PPD (P < 0.05) which was statistically significant, greater CAL gain and greater mean RDD reduction (P < 0.001) which was highly significant.Conclusion:In the surgical management of periodontal infrabony defects, Test group elicited in statistically significant PPD reduction, CAL gain, and better infrabony defect fill at 6 months’ postoperatively.
