Investigating the effect of photobiomodulation on pain and patient’s daily activities after surgical extraction of impacted mandibular third molar

INTERVENTION: The patients are randomly divided into two groups using sealed envelopes: 1. The Test Group (TG) consists of patients subjected to immediate postoperative intra‐ and extraoral photobiomodulation (PBM) using laser device K‐Laser Blu Dental that emit three wavelengths in combination; 445 (±5) nm, 660 (±5) nm, and 970 (±5) nm. The extraoral PBM parameters are a power of 550mW and a spot area of 5cm2. The intraoral PBM parameters are power of 200mW and spot area of 2cm2. 2. The Control Group (CG) consists of the patients not subjected to PBM. CONDITION: Improvement in pain and daily activities in patients who undergo surgical extraction of impacted mandibular third molar ; Surgery PRIMARY OUTCOME: Pain measured using a numeric rating scale (NRS) 4 times on 0, 1, 3, and 7 days after surgical intervention SECONDARY OUTCOME: 1. Painkiller intake, defined as the number of tablets of ibuprofen 400mg, measured using a custom‐made questionnaire on day 7 after surgery; 2. Patient’s daily activities measured using a custom‐made questionnaire on day 7 after surgery INCLUSION CRITERIA: 1. Patients undergoing the surgical extraction of a partially bony impacted mandibular third molar 2. Normal healthy patients of both genders 3. Age age = 18 years 4. No systemic disorders 5. No smoking habits 6. Absence of pericoronitis 7. No allergy to anesthetic solutions.
