Abstract:
Objective:To observe the effects of high-frequency current on rabbits dental pulp and to provide experimental evidences for clinic research.Methods:60 healthy 3 months old rabbits were divided into 4 experimental groups and 2 control groups.Dental pulps of experimental groups were treated with high-frequency currents with output power of 5 W,10 W,15 W and 20 W respectively.Then the devitalization degree of injury of dental capsule of experimental groups were compared with treated by complex toad composition,a type of traditional pulp devitalized medicine.Results:The effects between the devitalized effect of high-frequency current under 15 W and that of the traditional medicine were similarly.The concomitant injury of root canal tubal wall and periapical were not detected.Dental pulp of deactivation was easy to be extirpated and bled little while being extirpated.Conclusion:The reliability and safety of 15 W high-frequency output current could be the important parameter for clinic application research.
