Materials and methods: I- Patient selection: ten patients were selected from the outpatient's clinic of Oral Medicine, Periodontology, Diagnosis and Oral Radiology Department, Faculty of Dentistry- Mansoura University. Inclusion criteria:Patients with physiological gingival pigmentation with healthy gingival condition, the age range from 18-30 years old. Exclusion criteria: Patients with systemic diseases, smokers, pregnant women and patients taking any immunosuppression drugs. II- Study design: standard photographs and complete medical and dental history were recorded pre-operatively. We divided the anterior segment into right and left parts, one segment was treated randomly by cryosurgery and the other by electrosurgery. The pigmented area was assessed and compared pre-operatively and 3-6 months post operatively according to Dummett-Gupta Oral Pigmentation Index (DOPI). Results: In electrosurgery group, significance differences were found when comparing the preoperative score of DOPI versus both after 3 and 6 months. While no significance difference was found when comparing between the DOPI at 3 months and 6 months. Concerning cryosurgery group significance differences were found when comparing the preoperative score of DOPI versus both after 3 and 6 months, while no significance difference was found when comparing between DOPI at 3 months and 6 months. Mild degree of pigmentation occurred in 2 cases in both groups which was not esthetically significant. Conclusions: Electro-surgery and cryosurgery techniques were helpful for removal of gingival pigmentation with no recurrence significance for 6 months observation. Clinical Significance: There was no significant difference in recurrence between cryotherapy and electro-surgery groups. | ||||
