Description of intervention(s) / exposure
The CONSORT guidelines 2010 will be followed for reporting the present study. Patients who fulfilled the eligibility criteria will be provided with the study information sheets at the visit, to allow sufficient time to consider whether or not they wished to participate. Preoperative radiographic examination including panoramic or periapical radiographs will be undertaken for all patients.

Preoperative data for each patient encompassed age, gender, , smoking habits, alcohol consumption, indications for extraction, tooth location, and the presence/absence of apical radiolucency. This comprehensive information aims to understand the diverse factors influencing tooth extraction outcomes, particularly in the context of platelet-rich plasma/Fibrin (PRP/PRF) application.

Platelet Rich plasma and Fibrin concentrate preparation

To prepare Platelet-Rich Fibrin (PRF), 5 ml of whole venous blood is collected in each of two sterile vacutainer tubes without anticoagulant. The tubes undergo centrifugation at 3000 rpm for 10 minutes, resulting in three layers: the lower red fraction (red blood cells), the upper straw-colored layer Platelet rich plasma PRP , and the middle fraction, which is collected 2 mm below the lower dividing line, representing the PRF.
Third Molar Extraction
A full-thickness mucoperiosteal flap wIll be raised, and one releasing incision will be made as needed to allow socket examination and facilitate closure. Tooth extractions will be performed in 60 minutes. Post-extraction, sockets In the PRP /PRF group, sockets will be filled with Platelet-Rich Plasma and PRF, while the control group Will receive none. Mucosal flaps will be closed using resorbable sutures, ensuring complete soft tissue closure. Antibiotics will be prescribed; post-operative pain control will be provided with pain killer .

Outcome measures
Health-related quality of life index

The health-related quality of life questionnaire assessed patient perception of recovery after tooth removal in four main areas:
pain,
oral function,
general activity
and other symptoms.

Pain definitions referred to the severity of pain and the consumption of analgesics.
Oral function dealt specifically with the ability to eat food, swallowing, mouth opening and speech.
General activity variables targeted ability to practise routine daily activities, sleeping and school/ work attendance.
Other symptoms included: presence of swelling, bruising, bleeding, bad taste or halitosis and food stagnation in surgical sites.

For each question, the patients will be ask to mark the answer best describing how they felt (1, not at all; 2, very little; 3, some; 4, quite a lot; and 5, very much).

The VAS consisted of a 10-cm line anchored at one end by the label ‘No pain’ and at the other end ‘Worst possible pain’. The patients were given a form with seven scales for the respective days after extraction. The questionnaire also included follow up visit assessment on day 1,3 and 7 and daily doses of the analgesics consumed on each postoperative day.

Socket complications

The patients will be assessed 1 week after extraction for an assessment of socket complications, if any. Normal healing was recorded on observation of an alveolus with normal granulation tissue in the presence or absence of pain. Criteria for socket complications were:

• Alveolar osteitis diagnosed by the presence of a persistent throbbing post-operative pain in and around the extraction socket, will not adequately relieved by prescribed analgesics.

Other complications will also be assessed
Flap Dehiscence
Flap dehiscence
Infection




Soft tissue healing index

At the same post-operative appointment at 1 week following extraction, an assessment of the soft tissue surrounding the socket using the healing index of Landry et al will carry out to evaluate the extent of soft tissue healing after tooth removal. This intended to assess and grade the colour of tissues, epithelialisation of wound margins, presence of bleeding on palpation, granulation and suppuration. Two oral surgeons will carried out the assessments independently.

Radiographic assessment
For the assessment of the newly formed bone in extraction sockets, standardised periapical radiographs will be taken .Two methods of radiographic assessment will be carry out: a subjective evaluation and bone density analysis.

Two observers, will carry out a radiographic evaluation of the bone density of the sockets. The observers, who will be both unaware of the patient allocation to PRP/PRF or control groups, will ask to assess bone density on two different automated softwares.
The observers will meet for calibration and discussions on image characteristics, and evaluations will be made by consensus agreement of the two observers.
In order to analyse the radiographic images by the image analysis software. All radiographs will be digitised at 600 dpi spatial resolution and 8-bit depth . An automated analysis of the images will be carry out through the use of the
image J histogram and adobe photoshop CS2 software.

For image analysis, three areas of interest (AOIs) or sampling boxes will be select for each socket:

• Sample one: the upper border of the AOI box will locate approximately 2 mm below a line connecting the mesial and distal margins of the extraction socket.

• Sample two: the AOI box will locate in the middle part of the socket.

• Sample three: the lower border of the AOI box will locate approximately 2 mm coronal to the most apical extension of the socket visible on the radiograph.

This results in three AOIs for multi-rooted teeth. Dimensions of the AOI boxes will standardised at 1 mm in height (apical-coronal) and 1 mm in width (mesial-distal).

outcomes, differences between the PRP/PRF and control groups will be tested by non-parametric MannWhitney U-tests. Chi-square tests will be used to test differences in healing complications and subjective radiographic evaluation outcomes between groups. The statistical significance of any differences in trabecular parameters between the groups will be determined using independent sample t tests. All comparisons will be conducted at a 5% level of significance.
