The aim of the present study is to clinically and radiographically compare the effectivness of Scaling and Root Plannig (SRP) in association with lipo-curcumin gel (LC) respect SRP+ lipo-gel (L), SRP+ discharged (D) gel and SRP alone. This study will be designed as a randomized clinical trial of 12-month duration. A total of 40 patients will be recruited and randomly equally distributed into 4 groups: an experimental group treated with SRP + LC, a first control group treated with SRP + L, a second control group treated with SRP+D and a third control group SRP alone. Each defect will be treated with an ultrasonic scaler with dedicated thin tips for supra- and subgingival debridement associated with hand instrumentation under local anesthesia. Caution will be taken to preserve the stability of soft tissues. Following SRP, experimental and control sites will be randomly chosen. The test sites will be t filled with a Lipo-Curcumin gel and sealed with cyanoacrylate. In the first control group the defects will be be filled with a Lipo gel and sealed with cyanoacrylate. In the second control sites he pocket defect will be filled with a discharged gel and sealed with cyanoacrylate, in the third control group SRP alone will be performed. Pre- and post-treatment clinical measurements were performed by an examiner blinded to the treatment modalities using a graded periodontal probe (HuFriedy UNC 15). Before the treatment and at 6 and 12 months post-treatment, all patients were examined by measuring the clinical attachment level, probing depth, gingival recession, full-mouth plaque score and bleeding on probing.
