Abstract

Objective: Postoperative edema and pain are common third molar surgery side effects, that normally happens with local anesthesia. The low-level laser (LLLT) method has been universally recognized as a cell bio-modulator that is employed to accomplish optimum beneficial effects. It reduces the pain reaction, stimulates local microcirculation and wound healing, and promotes a fast healing, thus enhancing the patient's quality of life. We intended to ascertain the LLLT efficacy in improving mouth opening following the impacted third molar extraction in this research.

Methods: This randomized clinical trial was carried out on ninety cases who had impacted mandibular third molars in similar positions. Group A was allocated to intra-oral LLLT, Group B to extra-oral LLLT, and Group C to the control group. All participants were evenly divided into these three categories. The outcome that was assessed was the pain degree, alongside the postoperative edema and recovery at the operation site.

Results:  Postoperative pain and edema were calculated on 1st and 7th day. All these parameters were lower in LLLT patients (p>0.05).

Conclusions: After the impacted mandibular lower wisdom tooth surgical extraction, the LLLT application was effective in mitigating postoperative complications, for instance facial edema and pain.
