Abstract
One hundred twenty mandibular first molars and (96) maxillary first molars of Arabic permanent dentition were studied morphologically in vitro, using visual examination to detect number of roots, and apical foraminae, a radiographic investigation was formed to detect number of canals and a clearing or (transparent) technique was performed to emphasize the results obtained, the clearing technique was performed by decalcification of teeth and injecting them with a dye, number of roots, root canals and apical foraminae were detected and calculated as follow (98.33%) of the mandibular first molars had two roots and (1.66%) had three roots (one distal & two mesial), the maxillary first molars had three roots (one palatal & two buccal) in (100%) of teeth examined,(10%) of the mandibular first molars had two canals,(86.7%)had three canals and (3.3%) had four canals. The maxillary first molars did not have two canals,(82.3%) had three canals & about (17.7%) had four canals. The number of apical foraminae in the mandibular first molar were found to be two in (15%) of the teeth, three in about (84%) and four apical foraminae in less than (1%) of the teeth, The maxillary first molars had three apical foraminae in about (85.4%) four apical foraminae in (14.6%) of the teeth examined.
