About this trial

This is an interventional prevention trial for Bisphosphonate-Associated Osteonecrosis of the Jaw focused on measuring Platelets, fibrin, growth factors, bisphosphonates, tooth extraction

Eligibility Criteria

50 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • patients taking bisphosphonates whatever the indication, the type, the administration and the duration of treatment (we include patients taking or having taken bisphosphonates, even several years ago)
  • And who need tooth extraction (not recoverable in conservative dentistry and symptomatic tooth: dental and periodontal infections, symptomatic traumatic tooth fracture).

Exclusion Criteria:

  • pregnant women
  • younger than 50 years old
  • jaw's radiotherapy
  • history of jaw osteonecrosis
  • jaw metastasis from an other cancer

5. Study Description

Brief Summary
This prospective study will include patients taking or having taken bisphosphonates and needing dental extractions. The aim of this study is to validate the contribution of PRF (Platelet Rich Fibrin) in tooth extraction sites. In the test group (PRF) and in the control group (no PRF), we use the same atraumatic extraction protocol associated with the same antibiotic procedure.
Detailed Description
Dental extractions are the main cause of jaw osteonecrosis in patients taking oral or iv bisphosphonates. This prospective randomized study will include a cohort of 100 patients treated with bisphosphonates (for benign or malignant conditions) and requiring dental extractions (non-retainable teeth for infectious, traumatic or parodontal reasons). 50 patients will benefit of PRF placement in the tooth extraction site (group 1) while 50 patients do not (group 2). The rest of the procedure will be the same in the 2 arms. In the literature, studies suggest a benefit from a long term antibiotherapy before and after tooth extraction. Extraction procedure should be the least traumatic as possible. The main objective of our study is to assess, after tooth extraction, the contribution of PRF in the prevention of jaw osteonecrosis induced by bisphosphonates. A follow-up period of one year after extraction is indicated.
