Abstract

This study is to determine the penetration of various medicaments such as Howe's ammoniacal silver nitrate and methyleneblue, to root canal dentin within given time (5,10,30 sec.) Followings are the results obtained from this study. 1) The dye stuff is more deeply penetrated according to the time elapsed. 2) According to the increase of age, the penetration ratio is decreased accordingly. 3) The penetration ratio of Howe's ammoniacal silver nitrate is higher than that of methyleneblue. 4) The permeability of the root canal dentin is gradually reduced as access to the apex.
