Eligibility criteria
All of the following criteria must be fulfilled for inclusion:
- Patient must be willing to read and sign a copy of the Informed Consent Form
- Males and females ≥ 25 years old;
- Patients who are currently or previously treated with antiresorptive therapy alone or in combination with immune modulators or antiangiogenic medications for the management of cancer;
- Patients who are treated with antiresorptive therapy, bisphosphonates, for osteoporosis for more than 5 years;
- Patients who have been treated with antiresorptive therapy, bisphosphonates, for osteoporosis for less than 5 years and being concurrently treated with a systemic glucocorticoid;
- Patients who are treated with denosumab in the last nine months and being concurrently treated with a systemic glucocorticoid;
- Patients who are on the high-risk category to develop MRONJ based on the SDCEP guidance;
- Patients who require dental extractions (one per quadrant per patient) of premolar or molar teeth which are irrational to treat for any reason;
- Patients with a history of MRONJ.
The following patients will be excluded:
- Patients with MRONJ at the area of extraction;
- Patients with history of radiotherapy in the area of treatment;
- Patients with metastatic bone disease in the area of treatment;
- Self-reported pregnancy or lactation (this criterion is due to oral tissue changes related to pregnancy and nursing which can affect interpretation of study results);
- Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with trial participation or investigational product administration or may interfere with the interpretation of trial results and, in the judgement of the investigator, would make the subject inappropriate for entry into this trial;
- Dental extractions in people who are systemically unwell and who require hospital admission;
- Patients with poor glycaemic control (uncontrolled diabetes);
- Current smokers or smokers who have quit less than 10 years ago (including e-cigarettes)

A-PRF extraction sockets
|
For patients in the A-PRF group, venepuncture will be performed with a tourniquet, a butterfly needle (such as a 21-gauge Vacutainer Safety-Lok), and A-PRF blood bottles. Two 10 mL vials of blood will be obtained. The vials will be centrifuged at 1300 rpm using the Choukroun Duo Quattro PRF Centrifuge for 14 min. For patients on anticoagulant medication, the vials will undergo further centrifugation for 2 minutes. The A-PRF clots are then removed from the tube and separated from the red blood cells and platelet-poor plasma. They are then placed in an expression kit for 10 min (which will be monitored using a timer) to drain and compress. Once the membranes have been compressed for at least 10 minutes, they will be placed in the extraction socket and secured with 4-0 PTFE sutures. |

Proteomic biomarker expression changes in wound exudate (NSAF-based analysis)
大体时间:At 1, 3, 7 and 15 days post-extraction
|
Wound exudate from the three groups will be analysed to assess for changes in protein expression and signalling pathways during early wound healing. A small sterile medical grade PVA sponge will be used to collect the wound exudate from the extraction socket (such as NETCELL® PVA Microspheres, Network Medical Products Ltd, North Yorkshire, UK). Analytes involved in the healing process such as angiogenesis, wound healing, inflammation, bone remodelling, and formation will be selected based on the pathways identified in the genomic and proteomic work and literature search performed by our group. Multiplex (Luminex, R&D systems, Minneapolis, MN, USA) immunoassays will be designed specifically for quantitative analyses in the wound exudate of the socket. The molecular (proteomic) changes of wound exudate of the dental extraction socket will be assessed at 1, 3, 7, 15 days after extraction based on the Normalised Spectral Abundance Factor (NSAF) proteomic analysis. |
