Resumen
The maxillary first premolar (MFP) presents a highly variable and complex root morphology, it is also one of the teeth most likely to suffer vertical root fractures. The aim of this study was to describe the morphology of the root and root canal system of the MFP in a Chilean population using Cone-Beam Computed Tomography (CBCT). One hundred and twenty-one MFP were evaluated (60 left and 61 right), belonging to subjects of both sexes. Descriptive and statiscal analysis of the data was carried out, with a value of P < 0.05 being statistically significant. One root was observed in 71 % of teeth and two roots in 29 %, statistically significant differences were observed in the number of roots by sex (p<0.05). Two root canals were found in 69.5 % of teeth and one canal in 30.5 %. In terms of morphological classification, 41.3 % of cases were Vertucci Type IV. The proximal cementodentinal walls were the thinnest. The MFP presented a high degree of morphological variation in a Chilean subpopulation.
