title: Comparison of applying particulate demineralized bone matrix (DBM), putty DBM and open flap debridement in periodontal horizontal bone defects. A 12-month longitudinal, multi-centre, triple-blind, split-mouth, randomized, controlled clinical study. Part 2 - evaluation of the interdental soft tissue.
abstract: To date, there have been many studies clinically evaluating periodontal regenerative procedures by the help of routinely used hard and soft tissue parameters; however, these parameters are not capable of assessing interdental soft tissue located above the regenerative periodontal surgery area. The purpose of this study was to assess interproximal soft tissue changes following application of (i) particulate form demineralized bone matrix (DBM), (ii) putty form DBM and (ii) open flap debridement (OFD, control), using modified curtain technique in the treatment of interproximal suprabony (horizontal) defects located in anterior maxillary region, as previously reported. Twenty-five chronic periodontitis patients with 125 interproximal surgery sites (radiologically >or=4 mm horizontal bone defect) were also participate in this second stage of the triple-blind, split mouth, randomized, controlled clinical trial. Surgery sites were assessed by (i) plaque index (PI), (ii) gingival index (GI), (iii) the presence of interdental soft tissue clefts or craters and (iv) the loss of interdental papilla height by using papilla presence index (PPI), during the healing period. At the baseline and 3, 6, 9 and 12 months after the operations, these measurements were repeated. In all groups, there is a significant increase in the prevalence of soft tissue cleft and crater formation (P < 0.01), with increase in PI and GI scores at interdental soft tissue defect areas (P < 0.001), 3 months after the operations. There was also an increase in PPI scores after the operations in all treatment groups (P < 0.01). Three procedures affected the interproximal soft tissues similarly. There was no significant difference among groups in terms of all parameters (P > 0.05). Particulate DBM, putty DBM and OFD demostrated similar interproximal soft tissue changes especially increasing interproximal PI and GI scores in 3 months follow-up.
