| Research Abstract |
To evaluate the hemostasis and reparative dentin induction by the high frequency radio wave generator, we made exposed pulp artificially in maxillary first molar in rat. Compared the cotton pellet moisture with Sodium hypochloride by gentle pressure with high frequency radio wave generator, high frequency radio wave produced reparative dentin having high quality. And also we tried to examine the effect to the reparative dentin formation exposure by using K files. Pulp expanded by No.30 K file has showed good quality of reparative dentin formation, however by over No.50 K file was formed low quality reparative dentin formation with tunnel like defect. In these results, indicated that the hemostasis condition or exposure area can affect to the dentin regeneration and inflammation of the pulp.
