Summary  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 ≥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
