The aim of this article is to analyze the reliability and accuracy of root angulation measurements of posterior teeth in lateral cephalic radiographs and cone beam tomography (CBCT) of a group of students of the Faculty of Dentistry of the University of Cuenca, by means of Nemocast.
A total of 40 individuals were examined, of which, according to the inclusion and exclusion criteria, 12 ondividuals were excluded, having as a final sample 28 individuals, of which 28 cone-beam tomographies and 28 lateral cephalic radiographs were examined, the analysis of the inclination of 336 posterior pieces. The occlusal plane of each patient was identified, determined from the upper incisal edge of the central incisor to the mesiobuccal cusp of the maxillary first molar. Subsequently, lines were drawn at the level of the longitudinal axis of the maxillary and mandibular teeth to determine their inclination in the Nemocast program. Techniques such as observational and statistical were used where data was collected in Microsoft Excel 2010 tables.
Regarding the results, it was determined that the CBCT has greater precision and reliability compared to the lateral teleradiography of the skull, where the average angulation of the posterior teeth is 90.26°. The upper right first premolars presented greater angulation (94.11°). The lower left first molars presented the lowest mesiodistal angulation of 87.83°. On the other hand, in lateral head radiographs the average angulation is 96.2°. The upper right first premolars presented the greatest angulation (105°) and the lower right second premolars presented the lowest angulation of 91.3°.
