The objective of this study will be to evaluate a new protocol for the surgical treatment of periodontal disease with two novelties: to make a single incision in the midline of the interproximal area to respect the vascular supply and preserve the granulation tissue with regenerative potential.
The investigators will carry out a controlled and randomized clinical trial with a control group (n=25; modified Kirkland flap) and a test group (n=25; experimental surgical protocol: incision in the mid-interproximal area of the papilla and preservation of the granulation tissue).
Clinical parameters will be taken at the time of surgery and 12 months follow-up: bleeding on probing (BoP), clinical attachment level (CAL), residual probing depth (rPD),Probing pocket depth reduction (PPDr), recession (REC), interproximal gingival recession (iGR), width of keratinized gingiva (KT), gain of supra-alveolar clinical attachment (SUPRA-AG), early wound healing index (EHI).

| periodontal surgery | Procedure | A sulcular incision will be made in the affected teeth, followed by an incision from the buccal aspect in the mid-portion of the interproximal tissues The buccal and lingual flaps will be elevated. For periodontal granulation tissue preservation group, the soft tissues covering the alveolar crest will be prepared. A third incision will separate the pocket epithelium from the soft tissue (granulation tissue) attached to the bone. The pocket epithelium will be removed. The root surfaces will be carefully scaled and planed in both groups. Ethylenediaminetetraacetic acid (24%) will be applied to the root surfaces and removed after 2 minutes with abundant saline solution. In the experimental group, the preserved attached soft tissue and the space between it and the root surface will be irrigated with 10% polyvinylpyrrolidone-iodine. Finally, the flaps will be positioned and sutured. |
