About

Randomized controlled parallel designed clinical study aimed to compare vestibule depth gain and dimensional changes of wound area in individuals who underwent vestibule deepening surgery using diode laser and conventional technique

Full description

52 systemically healthy patients aged between 18 and 53 years (10 males and 42 females) with inadequate vestibular depth and insufficient attached gingiva in the anterior mandible were included in this randomized examiner- and patient-blinded, parallel design study. Following nonsurgical periodontal treatment, patients were divided into 4 groups as follows: a) diode laser (L); b) diode laser+Low level laser therapy (LLLT); c) conventional surgery and conventional surgery+LLLT, and vestibule deepening was applied to all subjects either with scalpel or laser assisted.

Scalpel surgery was performed as Clark's vestibuloplasty. A local anesthetic was administered bilaterally to the mental area. Then, a horizontal incision was prepared at the mucogingival junction with a scalpel blade 15c. All the muscle fibers over the periosteum were resected carefully. Following, the mucosal flap was sutured to the depth of the vestibule sulcus with 4-0 polypropylene suture material, once every 4 mm, from a total of 5 regions.

Laser assisted vestibuloplasty was performed using diode laser. Local anesthesia was achieved in the same manner as the control group (scalpel surgery). Laser irradiation was performed in continuous wave mode, using a 980 nm diode laser with a power of 1.5W, 600 μm optical fiber. After adequate local anesthesia, ablation was started from the mucogingival junction and performed with horizontal movements parallel to the bone. The muscle attachments were slowly released until the deepest point of the wound site was 5 mm. The mucosal flap was not stabilized with sutures and periodontal dressing was not used to cover the wound area.
