Salivary α-Amylase as a Non-Invasive Biomarker of PRF-Enhanced Wound Healing After Third Molar Surgery
This randomized clinical study evaluated salivary α-amylase as a non-invasive biomarker of early wound healing after mandibular third molar surgery. The study compared patients who received platelet-rich fibrin (PRF) in the extraction socket with patients who received standard surgical treatment without PRF.
PRF is a material prepared from the patient's own blood and is used to support tissue healing after surgery. Salivary α-amylase is an enzyme found in saliva that may reflect postoperative stress, inflammation, or healing responses. In this study, saliva samples were collected on postoperative days 0, 3, and 7 to measure α-amylase activity.
The study included adult patients aged 18 to 60 years who underwent impacted mandibular third molar surgery at the Dental Hospital of Hasanuddin University, Makassar, Indonesia. The main purpose was to determine whether PRF placement changes salivary α-amylase activity compared with no PRF during the first postoperative week.

Descrizione dettagliata
This study was designed to evaluate whether platelet-rich fibrin (PRF) placement after impacted mandibular third molar surgery is associated with changes in salivary α-amylase activity during the early postoperative healing period.
Salivary α-amylase was selected because saliva provides a non-invasive medium for monitoring biological responses after oral surgery. PRF was used as an autologous material prepared from the patient's own blood and placed into the extraction socket before suturing. The comparison group underwent the same surgical procedure without PRF placement.
Participants were assigned to two parallel groups: a PRF group and a non-PRF group. Saliva samples were collected during the first postoperative week, specifically on postoperative days 0, 3, and 7. The study compared salivary α-amylase activity between groups and also described changes over time within each group.
The study was conducted at the Dental Hospital of Hasanuddin University, Makassar, Indonesia. Laboratory analysis of salivary α-amylase was performed at the HumRC Laboratory, Faculty of Medicine, Hasanuddin University. The findings are intended to clarify whether salivary α-amylase can serve as a useful non-invasive biomarker for monitoring early wound healing after PRF-assisted mandibular third molar surgery.

Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: PRF Group
Participants in this arm underwent mandibular third molar surgery followed by platelet-rich fibrin (PRF) placement in the extraction socket before suturing.
|
Platelet-rich fibrin (PRF) was prepared from the participant's own venous blood.
A 10 mL blood sample was collected into dry sterile glass tubes without anticoagulant and centrifuged at 2700 rpm for 12 minutes.
The resulting PRF clot was compressed into a thin fibrin membrane and placed into the mandibular third molar extraction socket before suturing.
The intervention was used as an autologous biologic material to support postoperative wound healing after mandibular third molar surgery.

Nessun intervento: Non-PRF Control Group
Participants in this arm underwent the same mandibular third molar surgical procedure without platelet-rich fibrin (PRF) placement.
