Abstract
The tensile strength of treated bovine grafts was comparatively evaluated regarding to enzyme used, its activating time and tanning method.
A quality of enzyme was not a significant factor and the only difference was related to its activation time. As a result nynhidrin test, tensile test and histological analysis, activation time of 2 1/2 hours was considered to be appropriate in 1% ficin and 3 1/2 hours in 1.5% papain. As for the tanning agents, neo-chrome was relatively superior to others in terms of flexibility. No difference was observed between glutar aldehyde and formaldehyde.
