Platelet Rich Fibrin With 1% Metformin Gel for Treatment of Intrabony Defects
120 participantsStarted 2013-11
Plain-language summary
ABSTRACT:
Background: Platelet-rich fibrin (PRF) is a second-generation platelet concentrate which releases various growth factors that promote tissue regeneration. Metformin (MF), a member of biguanide group has been shown to facilitate osteoblast differentiation and thus may exhibit a favourable effect on alveolar bone . Current study was designed to evaluate the combined efficacy of PRF and 1% MF gel with open flap debridement (OFD) in treatment of intrabony defects in chronic periodontitis (CP) subjects.
Methods: One hundred and twenty subjects with single defects were categorized into four treatment groups: OFD alone, OFD with PRF, OFD with 1% MF and OFD + PRF+1% MF. Clinical parameters like site specific plaque index (PI), modified sulcus bleeding index (mSBI), probing depth (PD), relative attachment level (RAL) and gingival marginal level (GML) were recorded at baseline before surgery and 9 months post-operatively. Percentage radiographic intra-bony defect depth reduction was evaluated using computer-aided software at baseline and 9 months.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Presence of 3- wall intrabony defects ≥3 mm deep (distance between alveolar crest and base of the defect on an intraoral periapical radiograph \[IOPA\] ) along with an interproximal probing depth (PD) ≥5 mm after phase I therapy (scaling and root planing \[SRP\] ) in asymptomatic molar teeth.
Exclusion Criteria:
* Aggressive Periodontitis subjects
* Subjects with systemic conditions known to affect the periodontal status
* Medications known to affect the outcomes of periodontal therapy
* Hematological disorders and insufficient platelet count (\<200,000/mm3)
* Pregnancy/lactation
* Smoking and tobacco use in any form
* Immunocompromised individuals. Those having unacceptable oral hygiene (plaque index \[PI\]16 \> 1.5) after re-evaluation of Phase I therapy were also excluded from the study.
* In addition, teeth with furcation defects, non vital teeth, carious teeth warranting restorations and mobility of at least grade II were also excluded.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
