L-PRF vs PBM on Extraction Socket Healing

Comparative Evaluation of Pain, Soft Tissue Healing and Density of Newly Formed Bone Tissue in Surgical Extraction Sockets After Leukocyte and Platelet Rich Fibrin and Photobiomodulation Applications

The aim of this study is to compare leukocyte and platelet-rich fibrin (L-PRF) and photobiomodulation (PBM) applications, which have been repeatedly reported to be superior to control groups, in terms of pain, soft tissue and bone healing in tooth extraction sockets.

After sample size calculation, healthy volunteers were included in the study. Both teeth of these individuals with bilaterally impacted wisdom teeth were extracted simultaneously. Photobiomodulation (PBM) or leukocyte and platelet rich fibrin (L-PRF), an autogenous blood product, was randomly applied to the right or left side extraction sockets. Volunteers were called for repeat sessions (days 2,4,7,7,11,11,14,18 and 21) for the PBM treated side. Follow-ups were performed for pain (days 2,4,7) and soft and bone tissue healing.

Inclusion Criteria:

• American Society of Anesthesiologists (ASA) Class-I healthy volunteers
• Between 18 and 40 years of age who had wisdom teeth (Pell and Gregory Class II, Position B) with bone retention in bilateral symmetrical position with an indication for extraction, and had second molars in the mouth,
• Not use steroids or anti-inflammatory drugs in the last 3 months.

Exclusion Criteria:

• Patients with pericoronitis,
• Smoking habits
• Active periodontal disease
• Pregnancy,
• Breastfeeding
• Unable to give personal consent, and those with missing physical examination and follow-up records were excluded.
