• Easy to handle
• Easy to knot
• Minimal tissue reaction
• Maintain tensile strength until tissue has healed
• Narrow diameter to minimise tissue damage and scarring
• Unfavourable surface for bacterial colonisation

1. Irrigate the area with isotonic solution and remove excessive clots 2. Patient is then instructed to bite on the gauze pack until the general condition has
been evaluated.3. Patient’s blood pressure and pulse rate should be checked.4. Administer local anaesthetic just enough to achieve anaesthesia in desired area.
(Lidocaine 2% 1:80.000 adrenaline) Avoid giving large amounts of LA that will temporarily stop the bleeding but then will result in bleeding later on.
5. Once anaesthesia is obtained, the extraction wound is examined to determine the source of bleeding. Determine whether the bleeding is from the soft tissues (gingiva), the alveolus’ bone or both.
6. Bone bleeding: pack local haemostat into socket7. Secure haemostat with sutures8. Soft tissue bleeding - local haemostasis - diathermy or silver nitrate

In addition to serving as a mechanical obstruction to bleeding, these materials affect the coagulation process. In contact with blood, collagen causes aggregation of platelets, which bind in large numbers to the collagen fibrils. The aggregated platelets degranulate, releasing factors such as thromboxane A2 that assist in the formation of a clot. The sponge also provides a 3-D matrix for strengthening the blood clot.
Haemostatic Collagen These products (eg, CollaPlug, CollaTape, and Helistat [Integra LifeSciences]) are soft, white, pliable, nonfriable, coherent, sponge-like structures.

Management of patients in anticoagulation
Praxada® - Stop drug 24 hrs prior to an invasive surgical procedure in patient with normal renal function I.e. creatinine clearance >80ml/min
If creatinine clearance 50-80ml/min -increase time to 48 hours If creatinine clearance 30-50ml/min -increase time to 72 hours

Patients may be considered to have MRONJ if all of the following characteristics are present:
1. Current or previous treatment with anti-resorptive or antiangiogenic agents
2. Exposed bone or bone that can be probed through an intraoral or extraoral fistula in the maxillofacial region that has persisted for more than eight weeks
3. No history of radiation therapy to the jaws or obvious metastatic disease to the jaws.

MRONJ is comparatively uncommon following dental extractions
• 0.04 - 0.5% incidence in patients on ORAL BP
• 1.15% - 14.8% incidence in patient on IV BP
• There are an estimated 8.2-12.8 cases / million / year or 508 - 793 patients newly diagnosed each year in the UK

Recommendations
• Healthy diet and reducing sugary snacks and drinks • Maintain excellent oral hygiene • Use of fluoride tooth paste • Stop smoking • Limiting alcohol intake • Reporting any symptoms such as: loose teeth, numbness or altered sensation,
pain or swelling ASAP • Monitoring:
• Regular clinical check up • Consider imaging if suspected changes or symptoms • If any surgical procedure has been done monitor area until it has completely
healed (minimum 8 weeks or until area has healed)
If patient develops MRONJ - refer to specialistBRUZUAL CESRC

Why Leukocytes • Cytokines production
• Anti-inflamatory effects
• Anti-infectious effects
• Promote angiogenesis VEGF
PRF is also rich in Leukocytes

Leukocytes produce cytokines**
• 3 pro-inflamatory cytokines
• IL-6 / Interleukin 6
• IL-1β / Interleukin 1B
• TNF - α / Tissue Necrotic Factor alpha
• 1 retro-inflammatory Cytokine
• IL-4 / Interleukin 4
PRF is also rich in Leukocytes
One of the most powerful promoter of the VEGF
