Er:YAG and Nd:YAG-based low-level laser therapy (LLLT) with medical collagen improve third-molar extraction wound healing: a randomized controlled trial.

ABSTRACT: To evaluate whether Er: YAG surgery and Nd: YAG-based low-level laser therapy (LLLT), combined with medical collagen, improve early postoperative outcomes after extraction of impacted mandibular third molars. Adults undergoing surgical removal of mesioangular or horizontal impacted mandibular third molars were randomized equally (1:1:1:1) to blank control (BCG), collagen only (COL), lasers only (LAS), or collagen plus lasers (COL + LAS). Primary endpoints were pain (VAS; spontaneous and swallowing; POD1/3/7), swelling (POD1/3/7), trismus (POD1/3/7), and early mucosal healing (POD3/7). Secondary endpoints were bleeding (30 min post-extraction only), cutaneous induration/ecchymosis (POD7), alveolar osteitis (POD3/7), and local cytokines (IL-1β, IL-6, TNF-α; POD3/7). In 120 patients, COL + LA
