Evaluation of Electrosurgery and Cryosurgery in Removing Epulis Fissuratum Lesions

Introduction: The epulis fissuratum is a reactive inflammatory lesion associated with the periphery of ill-fitting dentures that histologically resembles the fibroma. For treatment of them, blade surgery, electrosurgery and cryosurgery and laser can be used. No need for sutures, preserving depth of vestibule and no or little bleeding are benefit of electrosurgery and cryosurgery over blade surgery. This study was done for comparing electrosurgery and cryosurgery for removing these lesions. Materials & Methods: In this clinical trial study, approved by ethical committee of Isfahan University of Medical Sciences, 20 lesions of epulis fissuratum with about 1cm size was randomly divided into two similar groups for removing by electrosurgery and cryosurgery. Healing time and pain after surgery were compared between the two groups. Survival analysis, /-test and repeated measure ANOVA were used for data analysis. Results: Healing time in cryosurgery was 14.5 days and in electrosurgery was 12.8 days. Survival analysis about clinical healing period showed a significant difference between the two methods (P=0.0216). Pain intensity was not significantly different between the two methods. Conclusion: Clinical healing period in electrosurgery was shorter than cryosurgery. Since, cryosurgery was done without anesthetic injection and had no unpleasant smell, it should be considered for some patients.
