Comparison of PRP & DFDBA vs. DFDBA in Intrabony Periodontal Defects

Comparison of Efficacy of Autologous Platelet - Rich Plasma Combined With Demineralized Freeze - Dried Bone Allograft Versus Demineralized Freeze - Dried Bone Allograft: A Randomized Clinical Trial in Central India

The purpose of this clinical trial is to compare the results in subjects with periodontitis using subjects own blood - Platelet-rich plasma (PRP) combined with bone graft material, namely, Demineralized Freeze - Dried Bone Allograft (DFDBA) or DFDBA alone in the treatment of bone defects around the teeth.

After being informed about the study and potential risks, 13 patients giving written informed consent and who meet the eligibility requirements were randomly allocated in a single blind manner (participants) to test group (PRP combined with DFDBA) or control group (DFDBA).

33 sites (18 test, 15 control unpaired defects) were treated - 1) to investigate the possible additional effects of PRP when combined with DFDBA, and 2) to compare the clinical and radiographic outcomes obtained in test and control groups,12 months post - operatively.

Inclusion Criteria:

• Outpatients

• radiograph showing at least one angular defect in any quadrant
• the involved teeth were vital and asymptomatic
• the site of interest had at least 2 mm of keratinized gingiva on the facial aspect of the selected teeth

Exclusion Criteria:

• Patients with abnormal platelet count
• allergic to chlorhexidine or any other medicine used in the study
• showing unacceptable oral hygiene compliance during / after the phase I therapy;
• pregnant or lactating mothers;
• smokers
• endodontically involved teeth
• patients under any medication known to interfere with periodontal healing. e.g., corticosteroids
