Prevalencia y características de conducto en forma de “C” para el segundo molar inferior en una población de Bucaramanga, Colombia. Evaluación mediante tomografía volumétrica de haz cónico

Abstract

Variations in the internal anatomy of human teeth make prior knowledge indispensable by means of diagnostic imaging aids, in order to achieve an adequate planning of the endodontic treatment as well as the preparation and disinfection of all the root canals; Each tooth has a characteristic internal anatomy. It is common to find ducts in the form of "C" for the lower second molars, this type of variation is a challenge for the endodontist because it requires special considerations for its treatment. The objective of this study was to evaluate the prevalence of this variation in lower second molars by studying three-dimensional images or cone beam volumetric tomography, obtained from patients who attended three radiological centers in the city of Bucaramanga, Colombia and its Metropolitan area. To search for the information, we entered the database of each tomograph with prior authorization and were selected with the document number of each patient. The brand of the equipment with which the images under study were obtained are; Isi-Icat, Planmeca and Galileos with voxel of size 0.25 mm. Tomographic images of lower second molars with complete crown-crown structure, closed apices and of the last eight years (2009-2017) will be included. In the evaluation of the tomographic images, the two evaluators participated, which were trained and calibrated interobserver to evaluate the reproducibility.
