Maxillary premolars are subjected to a combination of vertical and
lateral occlusal forces. Furthermore, premolars present with an anatomical shape and
unfavorable crown to root ratio, making them more prone to fractures than other
posterior teeth. When endodontic treatment is combined with mesio-occluso-distal
(MOD) cavities, the susceptibility to fracture increases.
