Efficacy and Safety of PERIOGEN in the Treatment of Periodontal Bone Defect

Study on the Efficacy and Safety of PERIOGEN in the Treatment of Periodontal Bone Defect - A Double-blind, Controlled, Randomised,Parallel,Multi-centre Study

PERIOGEN, containing rhPDGF and -beta-TCP, promotes gingival healing and corrects periodontal defects. This study will test the safety and efficacy of PERIOGEN in the treatment of periodontal disease

Sixty eligible patients with periodontal defect will randomly receive either beta-TCP implantation (control group) or PERIOGEN implantation, containing beta-TCP and rhPDGF (drug group). The specified primary and secondary end points related to efficacy and safety will be assessed during 6 months study period.

4. Radiographic base of defect ≥3 mm coronal to the apex of the tooth.

Exclusion Criteria:

1. Failure to maintain adequate oral hygiene (plaque index>2)
2. Pregnant and lactating women
3. History of oral cancer or HIV
4. Periodontal surgery on treatment-targeted tooth within the last year.

6. Study tooth exhibiting a class III furacation defect
7. Localized aggressive periodontitis
8. Radiographic signs of untreated acute infection at the surgical site
9. Recent history of smoking more than 20 cigarettes/day
