Abstract: Objective: To evaluate the clinical efficacy of combined treatments of ligating and electrotome on pregnacny epulis. Methods: A total of 69 pregnant women with pregnancy epulis were included in this study. According to the volume, the epulis was divided into solitary and multiple types. Treatment included combination of ligating therapy which contained pedicle ligation, segmenting ligation, suspension ligation, and micro electrotome resection. Results: All 69 cases gained different therapeutic effects. Cure rates in solitary and multiple types were 94.44% and 73.33%, respectively, and improvement rates were 5.56% and 26.67%, respectively. There was significant difference in treatment effect between two types of pregnancy epulis (P=0.003). Conclusion: It is a minimal invasive and safe treatment to ligate the epulis which reduces the blood supply and thus decreases the volume of epulis, followed by micro electrotome resection. The two therapies show a synergistic effect.
