Clinical Trial: Gingival Depigmentation by Diode Laser

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: Efficacy of810 nm Diode Laser on Gingival Pigmentation

Brief Summary: Physiologic gingival pigmentation(PGP) is the most common type of gingival pigmentation and cosmetic concern particularly in gummy smile patients. Laser therapy is an effective and noninvasive treatment option. The aim of this study was to evaluate the efficacy of diod laser on the treatment of PGP in patients.

Detailed Summary:

Preoperative and postoperative photographic and clinical observations about the gingival melanin pigmentation were made according to Dummett-Gupta Oral Pigmentation Index scoring criteria given by Dummett C.O. in 1964 The investigators classified pigmented gingiva in patients as:

  1. Mild:Pink to slightly brown
  2. Moderate:Deep brown or black
  3. Severe:Mixed in color Score in each tooth was taken including one full inter dental papilla. Observations were made in natural light. The assessment of the scoring of the pigmentation index were done by all the three examiners, and the agreed upon score was assigned to prevent individual variations.

The investigators compared the intensity of pigmentation in each patient in recall sessions after 1month and 3mounth postoperative.
