Brief Summary

Periodontal intrabony defects represent a major challenge for the clinician in periodontal therapy. If left untreated, these defects represent a risk factor for disease progression and additional attachment and bone loss. All patients will receive full mouth scaling and root planing and be re-evaluated to assess patient cooperation and maintaining good oral hygiene. Subjects who showed persistent PPD ≥ 5 mm with radiographic evidence of periodontal intrabony defect presence will be included and will be randomly allocated to one of two treatment groups.One group will be treated by surgical treatment and the defects filled by freeze-dried bone allograft mixed with enamel matrix derivative. second group will be treated by surgical treatment and the defects filled by freeze-dried bone allograft .Clinical periodontal parameters (PI, GBI, PPD, CAL) will be re-evaluated at 3, 6 and 9 months after surgery. CBCT will be taken after 9 months of surgery and the defect measurements will be recorded

Study Arms (2)

freeze-dried bone allograft combined with enamel matrix derivative

EXPERIMENTAL

The intrabony defects will be treated by surgical treatment and the defects filled by freeze-dried bone allograft mixed with enamel matrix derivative.

Procedure: Freeze-dried bone allograft combined with Enamel Matrix derivative

ACTIVE COMPARATOR

The intrabony defects will be treated by surgical treatment and the defects filled by freeze-dried bone allograft.

Procedure: Freeze-dried bone allograft

Interventions

The intrabony defects will be treated by minimally invasive surgical technique or modified minimally invasive surgical technique depending on defect extension, and the defects will be filled by freeze-dried bone allograft mixed with enamel matrix derivative. Enamel matrix derivatives are natural proteins that are produced in the developing dental follicle.The major components of EMD are amelogenins, a family of hydrophobic porcine tooth-derived proteins. They account for more than 95% of the total EMD protein content. Other proteins found in the enamel matrix include enamelin, ameloblastin, amelotin, apin and various proteinases, which have found in trace amounts in EMD. EMD adsorbs on decontamined root surfaces and alveolar bony defects and forms an insoluble scaffold complex.

The intrabony defects will be treated by minimally invasive surgical technique or modified minimally invasive surgical technique depending on defect extension, and the defects will be filled by freeze-dried bone allograft . Allogeneic bone graft refers to bony tissue that is harvested from one individual and transplanted to a genetically different individual of the same species, principally osteoconductive, although it may have some osteoinductive capability, depending on how it is processed.
