Pulpal reaction to tested medicaments during various time intervals(1, 7, 14, 28, 56
days) were evaluated histologically under light microscope. In Formocresol-ZOE group,
classical 3 different histological zones were observed with apical diffusion of fixation
zone, whereas none - to slight diffusion could be found. Only Glutaraldehyde - ZOE
group showed active fibrotic replacement. Generalized severe inflammation and internal
resorption were observed in Glutaraldehyde-Ca(OH)2 group and ZOE
control group. 5 minute glutaraldehyde(2%) pulpotomy using ZOE as base material
showed the best histological picture among all the tested materials.
