Effect of low-intensity laser treatment on pain after extraction of impacted mandibular third molars: a randomised, controlled, clinical trial

Choosing between intraoral or extraoral, red or infrared laser irradiation after impacted third molar extraction

“…A draw with 60 numbers was held to randomly allocate the subjects into five experimental groups. Opaque envelopes containing the information of the corresponding experimental group were identified with each number . The envelopes were sealed and remained in numerical order in a safe place until the time of the surgery.…”

“…The envelopes were sealed and remained in numerical order in a safe place until the time of the surgery. The draw and the preparation of the envelopes were performed by an individual not involved in the study .…”

“…The study was conducted with 60 subjects undergoing the surgical removal of impacted mandibular third molars at the Specialty Dental Center who agreed to participate after reading and signing a statement of informed consent. Subjects with systemic diseases, chronic pain or neurological/psychiatric disorder, current smoking habit, pericoronitis in the previous month, pregnancy, or current breastfeeding, a history of photosensitivity disorders or use of anti‐inflammatory agent, analgesic, or bisphosphonate drug in the previous 15 days were excluded . Figure summarizes the study protocol.…”

“…The mandibular third molar extractions were performed by two dental surgeons and a third person performed the preoperative measures and PBMT according to the group in which the patient would be entered (determined by the information contained in the opaque previously prepared envelope).…”

“…Ayrıca endojenöz endorfin sentezini uyarır, C tipi sinir liflerinin ve bradikinin aktivitesini azaltır ve ağrı eĢiğini değiĢtirir. 44 CO 2 lazer (dalga boyu 10.6 λm), fototermal (irreversible) etkisi ile vaporizasyon, karbonizasyon, hemokoagülasyon, protein denaturasyonu gibi yumuĢak doku yüzeyinde morfolojik değiĢikliklere neden olur. Fotoaktif etkisi (reversible) ile ağrıyı ve enflamasyonu azaltır, odontoblast benzeri hücrelerin farklılaĢmasını ve tamir dentini oluĢumunu sağlar.…”
