Abstract
This study was conducted in 12 subjects, with an esthetic complaint of hyperpigmented gingiva on the facial aspect of the anteriors. The patients were selected from outpatient Department of Periodontics, Sri Ramakrishna Dental College and Hospital, Coimbatore. AIMS AND OBJECTIVES: 1. To evaluate the efficacy of bur abrasion and cryosurgery for gingival melanin depigmentation. 2. To compare the rate of repigmentation, following bur abrasion and cryosurgery. MATERIALS AND METHODS: Study Design and Patient Selection: The subjects for this study were selected from the outpatient Department of Periodontics, Sri Ramakrishna Dental College and Hospital, Coimbatore. 12 patients of age around 18 to 30 were selected based on inclusion and exclusion criteria mentioned below to undergo gingival depigmentation. All the patients were treated for gingival depigmentation using cryosurgery for upper arch and bur abrasion for lower arch. Written consent was obtained from each patient prior to their inclusion in this study. Approval from Institutional Review Board (IRB) and Ethical Committee (EC) of Sri Ramakrishna Dental College and Hospital was obtained prior to implementation. Before undertaking any of the procedure, all the patients were reassured, supragingival ultrasonic scaling performed and oral hygiene instructions were advised. Inclusion criteria: 1. Diffuse continuous physiological pigmentation of the gingiva involving the facial aspect of anterior teeth, 2. Patients with esthetic concern, 3. Patients with good oral hygiene. Exclusion criteria: 1. Smokers, 2. Patients with compromised systemic health, 3. Patients with cold intolerance, 4. Patients under systemic medications. A comparative study was designed in relation to upper anteriors and lower anteriors. Upper anteriors was chosen for cryosurgical procedure and the lower anteriors for bur abrasion. The total surface area of pigmentation was measured with the help of 6 standardized photographs of each patient, preoperative, postoperative after 24 hrs, 7th, 30th, 90th and 180 days which was then calculated with help of a photo imaging software (Adobe CS 4). Patients with compromised systemic health, smokers and poor oral hygiene were excluded for the study. Oral prophylaxis and oral hygiene instructions were given to all the patients before performing the procedures. The final results were statistically analyzed and significance evaluated. From the results obtained, the following conclusions were arrived at: 1. Cryosurgical procedure and bur abrasion technique are highly efficient for the treatment of gingival pigmentation. 2. Statistical comparison of both the techniques in terms of efficiency was not significant. 3. The faster rate of repigmentation may be because the study was conducted in people of South India, who are more towards dark complexion. 4. The pain assessment, showed no statistically significant difference between cryosurgery and bur abrasion, but clinically patients preferred cryosurgery over bur abrasion, as it required no local anesthesia and post operative discomfort was also very minimal.
