This study was conducted to investigate root canal morphology of maxillary first premolars in a Jordanian population. Six hundred maxillary first premolars were collected, stained, and decalcified. Cleared teeth were examined and the following features were evaluated: (1) number of roots, (2) presence of furcation grooves, (3) location of apical foramina, (4) number and types of root canal, (5) number of lateral canals and isthmi, and (6) frequency of apical deltas. Of the six hundred maxillary first premolars 30.8% has one root, 63.2% has two, and 5.2% has bifid roots. Concerning root canal morphology, 79.7% had two canals with two separate apical foramina, whereas 3.3% of the teeth possessed type I canal systems. All two rooted maxillary first premolars showed furcation groove in the buccal roots. Maxillary first premolars are mainly two rooted and mostly have two canals. The presence of furcation groove should be kept in mind during both endodontic and prosthodontic procedures.
