Periodontal Flap Surgery along with Vestibular Deepening with Diode Laser to Increase Attached Gingiva in Lower Anterior Teeth: A Prospective Clinical Study

BACKGROUND: Chronic periodontitis in lower anterior teeth results in rapidly progressive gingival recession (GR), loss of alveolar bone, decreased vestibular depth (VD) with consequential tooth mobility, and tooth loss. Treatment option for such cases in this esthetically important area of the oral cavity includes extraction followed by implants for which sufficient bone height and mucogingival complex are a prerequisite. Henceforth, an attempt was made to prolong the life of lower anterior teeth and postpone the need for implants by the treatment of chronic periodontitis with periodontal flap surgery followed by vestibular deepening in single surgical procedure. MATERIALS AND METHODS: In this clinical, prospective study, conventional periodontal flap surgery was done on 74 sites in lower anterior teeth in 16 patients with attachment loss >5 mm due to chronic periodontitis. Vestibular deepening with diode laser at (wavelength - 810 nm, output power: 0.5–7 W, continuous wave, contact mode) was done after suturing the flap. All the clinical parameters: GR, pocket depth (PD), clinical attachment loss (CAL), width of keratinized gingiva, width of attached gingiva, and VD were assessed preoperatively after Phase I therapy and 6 months postoperatively. RESULTS: At all the 74 sites, there was highly significant gain in attached gingiva, keratinized gingiva, and VD (P ≤ 0.001). Highly significant reduction in PD (P ≤ 00.001), significant reduction in attachment loss (P ≤ 0.01) but no significant reduction in GR (P = 0.897) was observed. CONCLUSIONS: The combination of periodontal flap surgery with vestibular deepening with diode laser may be a suitable cost-effective treatment option to prolong the life of periodontally involved lower anterior teeth. The surgical technique can postpone the need for extraction of teeth along with all the intangible benefits of periodontal therapy.
