Effectiveness  Of Low Level Diode Laser (1064) And Acyclovir in Treatment Of Recurrent Herpes Labialis. (Comparative Clinical Study)

BACKGROUND Gingival melanin pigmentation (GMP) is a common aesthetic concern. The gold standard for depigmentation, is surgery. Recently soft tissue lasers have gained popularity. The purpose of this study was to compare and evaluate the clinical efficacy of surgical blade and laser treatment in terms of pain perception and wound healing outcomes, 7 and 14 days following the procedures for the treatment of gingival depigmentation. METHODS This 14 day follow up comparative clinical study, utilized a split mouth design, in the anterior region. Fifteen patients with moderate to heavy bilateral gingival pigmentation were included as per the criteria by Dummett et al. The patients’ right side (group 1) was treated with surgical blade and the left side (group 2) with diode laser (Picasso, AMD LASERS™) by a trained clinician. Pain perception was assessed using Visual Analog Scale (VAS) and wound healing was assessed using clinical parameters. RESULTS Data was analysed using paired t test and Wilcoxon’s signed rank test. P value of < 0.05 was considered statistically significant. On day 7, more than 70 % patients had slight pain in group 1. Whereas, 47 % experienced no pain in group 2. The mean difference in VAS scores between the groups at day 7, was statistically significant. No statistically significant distinction in wound healing was observed 7 days following both procedures. No pain, and complete epithelialisation was noted in both groups on day 14. CONCLUSIONS Pain experienced by the patients was slightly more in the scalpel group compared to laser. There was no difference in wound healing between both groups. KEY WORDS GMP, Gingival Melanin Pigmentation, VAS Scale, Depigmentation, Wound Healing, Laser, Surgical Blade, Split Mouth Design

Background: lip lengthening procedure is one of the surgical options for the correction of gummy smile in patients with short upper lip. Methods: A comparative clinical study was conducted on 15 patients requiring lip lengthening procedure for the esthetic correction of excessive gingival exposure with gummy smile. Scalpel was used in seven patients and diode laser in the remaining eight patients. Under infiltration anesthesia, about one cm strip of mucosa was excised at the vestibular depth and the mucosa of the lip was sutured to the alveolar mucosa. Results: The diode laser group demonstrated less postoperative pain and swelling. Regarding postoperative ecchymosis, three patients in the scalpel group developed ecchymosis and no cases were noted in the laser group, the difference was statistically significant. No patient in the laser group developed wound dehiscence and only one patient in the scalpel group had wound dehiscence at third postoperative day. Observed at one month postoperatively, the laser treated groups had less obvious scar than the scalpel group. Conclusion: Diode laser is a valuable tool in performing lip lengthening for gummy smile.
