The effect of endodontic therapy, post-hole preparation, and post placement on tooth models of maxillary central incisors was investigated. Two-dimensional photoelastic analysis of birefringent models, under load in a polariscope, indicated the relative stress magnitudes and concentrations at the cervical and apical regions. Within the limits of the method, the results suggest that enlargement of the canal increases cervical stresses and that post placement will decrease stresses in this region… CONTINUE READING
