Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study will be designed as a randomized clinical trial of 12-month duration. A total of 51 patients (each with a single infrabony defect) will be recruited and randomly equally distributed into 3 groups: an experimental group treated with SRP and rhPDGF, a first control group treated with SRP and collagen sponge and a second control group treated with 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 treated by inserting a collagen plug soaked for at least 15 minutes in a 1.5cc solution containing hPDGF-BB. In the first control group the infrabony defects will be treated with SRP and a collagen sponge soaked in saline solution. In the second control sites no further treatment will be carried out.
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.
Standardized radiographs of selected study sites will be taken at baseline and at the 6 and 12 months follow-up visits using the long-cone technique with a customized holder and a thermoplastic occlusal reference to allow reproducible positioning. All radiographs will be analysed by a dedicated dental software (Carestream Dental LLC Atlanta, GA, USA) to make linear measurements. The defect bone level (DBL), the defect angle (DA) and the radiographic defect area (RDA) will be evaluated.

SRP+rhPDGF
After SRP the infrabony defect will be filled with a collagen sponge soaked in rhPDGF.
SRP+rhPDGF
The infrabony defect will be debrided with the use of fine ultrasonic tips and mini hand instruments and will be treated with the application of a collagen sponge soaked in rhPDGF.
SRP+ collagen sponge
After SRP the infrabony defect will be filled with a collagen sponge soaked in saline solution.
SRP+collagen sponge
The infrabony defect will only be debrided with the use of fine ultrasound tips and mini hand instruments and will be treated with the application of a collagen sponge soaked in saline solution.
SRP alone
