Summary

The study is a randomized controlled clinical trial comparing the use of microneedling with vitamin C against injecting vitamin C for depigmentation in physiological gingival melanin hyperpigmentation in a group of patients attending the outpatient clinic of the department of Oral Medicine and Periodontology-Cairo University.

Conditions

  • Gingival Pigmentation

Interventions

PROCEDURE

Microneedling will be done with application of topical vitamin C paste for depigmentation

A Dermapen device will be used to microneedle the gingival tissue (model M8) with 24 microneedles arranged in rows, which is adjusted with 1.5 mm depth at the 6th mode speed of 700 cycles/min. It will be used in intermittent motion on the affected area for 30-40 seconds / tooth. Once bleeding points are observed on all areas of the pigmented gingiva, it will be irrigated using saline solution and dried using sterile gauze. Topical vitamin C powder (1000 mg/ml) will be mixed with saline, and the resultant slurry mix will then be applied to the gingiva for 10 minutes.

PROCEDURE

Vitamin C injection

1-1.5 ml Vitamin C will be injected into the gingiva, using an insulin syringe, once weekly, for 3 weeks. All the injection procedures will be performed by the same operator. The treated area will be left without dressing in both groups.
