Therapeutic Impact of 980 nm Diode Low-level Laser Therapy on Neurosensory Recovery Following Mandibular Third Molar Removal: A Case Report

Paraesthesia due to nerve injury is a common complication following the extraction of impacted mandibular third molars, often affecting the Inferior Alveolar Nerve (IAN). Low-Level Laser Therapy (LLLT) has shown promising results in promoting neurosensory recovery in such cases. This case report presents the management of postoperative nerve paraesthesia in a 24-year-old female patient using 980 nm diode laser therapy. The treatment was delivered in contact mode at 0.5 W, applying three joules per point for 30 seconds at each irradiation site. Sensory function was assessed using the Visual Analogue Scale (VAS), in-prick, and brush stroke tests (conducted at each visit for comparative assessment). Initially, the patient recorded a VAS score of 10. By the fourth session, the score decreased to eight. After ten sessions, complete recovery was noted in the chin, gingiva, and oral mucosa (VAS=0), with partial improvement in the lower lip (VAS=8) and mandibular left central incisor (VAS=6). Full recovery was observed after 20 sessions. This report suggests that LLLT is a safe, non-invasive, and effective modality for enhancing nerve regeneration and managing paraesthesia following third molar surgery.
