Inhibition zone were measured around antiseptic disks. 5. The results of 45 cases of experiments showed as follows. Average diameter of inhibition zone around phenol disk was 2.99 mm, camphorated phenol, 0.74 mm, formocresol, 13.46mm, formocresol (Korea), 12.7 mm, eugenol, 4.74mm, thymol, 16.46 mm.
