evaluation of three methods in the diagnosis of dentin cracks caused by apical resection.
to compare three various methods in the diagnosis of dentinal cracks formed in the apical third after root resection.one hundred extracted human maxillary central incisors were selected. the root canals were prepared with step-back technique. then 3mm from the apical end of all roots was cut perpendicular to the long axis of the tooth. the apical end of each root was evaluated to make sure ther...
