The aim of this study is to investigate the morphology of maxillary premolar root canal systems using cone beam computed tomography. The literature review was carried out through a literature review of studies published in recent years in the databases of PubMed/Medline, Scopus, LILACS and SciELO. The results show that cone beam computed tomography allows the visualization of three-dimensional structures, reducing image overlapping and allowing a better identification of more complex and variable channel structures, such as premolars. The maxillary first premolars had one to two roots, with a prevalence of type IV and II root canal systems. The maxillary second premolars also varied in number of roots between single-rooted and double-rooted, and had a higher prevalence of type I, II and IV canals. It is possible to conclude that premolars are teeth with high root variability and cone beam computed tomography are a good instrument to help the study of these morphological variations, reducing the possibility of errors in endodontic treatments.
