description	Introducción El diagnóstico temprano de periodontitis apical se realiza a través de imágenes diagnósticas. La tomografía computarizada de haz cónico (CBCT) actualmente es considerada la técnica radiográfica con mejores capacidades para identificar éste evento. El objetivo de este estudio fue determinar la prevalencia de periodontitis apical en 1858 dientes sin tratamiento endodóntico, evaluados en 152 tomografías computarizadas de haz cónico tomadas a pacientes que asistieron a consulta odontológica en la Universidad Santo Tomás Seccional Bucaramanga. Metodología Mediante un estudio analítico de corte transversal, fueron incluidas las tomografías computarizadas de haz cónico de dientes permanentes de personas de ambos sexos tomadas entre 2016 y 2017. Se evaluó la presencia de periodontitis apical mediante el índice CBCT PAI. La asociación entre el evento y variables como género, edad, diente afectado y cantidad de dientes que presentaron la patología por tomografía evaluada, se realizó mediante prueba de Chi2, valores de p0.05 se consideraron de significancia estadística. Resultados La prevalencia de Periodontitis apical encontrada fue de 19.7%. El 83.6% de estas lesiones (n=306) se ubicaron en el criterio CBCT PAI I ((>0.5 mm–1mm). Los dientes más afectados fueron el 13, 24 y 23 respectivamente. Respecto a la cantidad total de dientes afectados por tomografía evaluada, se evidenció que 19.7% de las tomografías analizadas (n=30) tenían un diente con evidencia de la patología y el 19.1% (n=29) dos dientes afectados. Conclusiones La prevalencia encontrada (19.7%) fue relativamente alta comparada con otros estudios reportados. En una Tomografía axial computarizada es posible observar Periodontitis apical de tamaño incipiente.

Cone beam computed tomography (CBCT) is currently considered the radiographic technique with the best capabilities to identify this event. The objective of this study was to determine the prevalence of apical periodontitis in 1858 teeth without endodontic treatment, evaluated in 152 CBCT taken from patients who attended a dental practice in a region of Colombia. Methodology Through a cross-sectional analytical study, CBCT of permanent teeth of people of both sexes taken between 2016 and 2017 were included. The presence of apical periodontitis was evaluated using the CBCT PAI index. The association between the event and variables such as gender, age, affected tooth and number of teeth that presented the pathology by assessed tomography, was performed by Chi2 test, p de 0.05 values were considered of statistical significance. Results The prevalence of apical Periodontitis was 19.7%. 83.6% of these lesions (n = 306) were located in the CBCT PAI I ((> 0.5 mm-1mm) .The most affected teeth were 13, 24 and 23 respectively. With respect to the total number of affected teeth in evaluated tomography, it was evidenced that 19.7% of the CBCT analyzed (n = 30) had one tooth with evidence of the pathology and 19.1% (n = 29) two affected teeth. Conclusions The prevalence found (19.7%) was relatively high compared with other studies reported. In a CBCT it is possible to observe apical Periodontitis of incipient size.Magíster en Odontologíahttps://www.ustabuca.edu.co/Maestríaapplication/pdfAtribución-NoComercial-SinDerivadas 2.5 Colombiahttp://creativecommons.org/licenses/by-nc-nd/2.5/co/Abierto (Texto Completo)info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Prevalencia de periodontitis apical en dientes no tratados endodónticamente evaluados en CBCTbachelor thesisTesis de pregradoinfo:eu-repo/semantics/acceptedVersionFormación de Recurso Humano para la Ctel: Trabajo de grado de Maestríahttp://purl.org/coar/resource_type/c_7a1finfo:eu-repo/semantics/bachelorThesisMaestria en OdontologíaApical periodontitisTooth not treated endodonticallyConventional cone beam tomographyRadiographic techniqueEndodonciaEnfermedades de los dientesTomografía computarizada por Rayos XDientes - RadiografíasPeriodontitis apicalDiente no tratado endodónticamenteTomografía convencional de haz cónicoTécnica radiográficaCRAI-USTA BucaramangaMiller WD.
