Clinical and Radiological Effect Of Platelet Rich Fibrin on the Healing of Periodontal Intrabony Periodontal Defects

Not Applicable

Completed

• Conditions: Chronic Periodontitis; Intrabony Periodontal Defect
• Interventions: Other: Anorganic Bovine Bone Mineral (ABBM); Other: Anorganic Bovine Bone Mineral and Platelet Rich Fibrin (PRF)

• Registration Number: NCT02836314
• Lead Sponsor: Baskent University

Brief Summary

The aim of this split mouth, single-center, controlled study is to compare the healing of intrabony defects treated with a combination of Anorganic Bovine Bone Mineral (ABBM)/Platelet Rich Fibrin (PRF) or Anorganic Bovine Bone Mineral alone. The hypothesis being tested in the study was that PRF would augment the regenerative effects of ABBM in human intrabony defects.

Detailed Description

Anorganic bovine bone mineral (ABBM) is extensively used in the treatment of intrabony defects. Platelet rich fibrin (PRF) is a new generation platelet concentrate with a simplified technique. Although there are some studies on the use of PRF in the treatment of intrabony defects, to date none of them evaluate its additive effects with ABBM. Therefore, a randomized, split mouth clinical trial was conducted to compare the healing of intrabony defects treated with a PRF/ABBM combination and to those obtained with ABBM alone. Using a split mouth design, 15 paired intrabony defects were randomly treated with either ABBM alone (control group) or with ABBM- PRF combination (test group). The following clinical parameters and radiographic measurements were recorded at baseline and six months postoperatively: plaque index (PI), gingival index (GI), probing depth (PD), gingival recession (GR), clinical attachment level (CAL), vertical bone loss, the depth of the defect and defect angle

Arm && Interventions

Group	Intervention	Description
Anorganic Bovine Bone Mineral	Anorganic Bovine Bone Mineral (ABBM)	Intervention: Anorganic Bovine Bone Mineral is applied to the periodontal intrabony defects
PRF and ABBM	Anorganic Bovine Bone Mineral and Platelet Rich Fibrin (PRF)	Intervention: Anorganic Bovine Bone Mineral and Platelet Rich fibrin is applied to the periodontal intrabony defects

Primary Outcome Measures

Name	Time	Method
Clinical attachment level change: The distance from cemento-enamel junction to the depth of the sulcus recorded by a periodontal probe at baseline and 6 months postoperatively	baseline and 6 months

Secondary Outcome Measures

Name	Time	Method
Vertical bone loss change: Distance between cemento-enamel junction and base of the defect measured in standardized radiographs at baseline and 6 months postoperatively	Baseline and 6 months
Probing depth change: The distance from the gingival margin to the depth of the sulcus recorded by a periodontal probe at baseline and 6 months postoperatively	baseline and 6 months
Radiographic defect angle change: Using the function 'angle' the defect angle can be measured by assessing the two lines that represent the root surface of the involved tooth and the bone defect surface at baseline and 6 months postoperatively	baseline and 6 months
