Resumen

Este estudio tuvo como objetivo evaluar la relación de las radiolucidez periapicales (PA) con la calidad del tratamiento del conducto radicular (RCT) mediante tomografías computarizadas de haz cónico (CBCT) de una población iraní. Este estudio transversal se realizó en 200 dientes tratados endodónticamente en exploraciones CBCT recuperadas de una clínica de radiología en Qazvin, Irán. Las vistas sagitales, coronales y axiales fueron evaluadas por un endodoncista y un estudiante de odontología de último año capacitado para detectar errores en el procedimiento del conducto radicular y la presencia/ausencia de radiolucidez PA en los respectivos dientes. La asociación de las lesiones PA con la edad, el sexo, la mandíbula, el tipo de diente, la presencia/ausencia de restauración coronal y la calidad del RCT se analizó mediante el modelo de regresión logística (alfa=0,05). La frecuencia de RCT de mala calidad fue del 75,3 % en los dientes con radiolucidez PA y del 15,5 % en los dientes sin ella. Se encontró una asociación significativa entre la calidad de la tomografía computarizada de haz cónico y las radiolucencias de la PA (P<0,001). La ausencia de restauración coronal también tuvo una asociación significativa con la presencia de radiolucencias de la PA (P<0,001). De los errores de procedimiento, la perforación, la obturación insuficiente y excesiva, la baja densidad de obturación (huecos) y el transporte del conducto se asociaron significativamente con la presencia de radiolucencias de la PA (P<0,05). La calidad de la tomografía computarizada de haz cónico tuvo una asociación significativa con el desarrollo de radiolucencias de la PA, de modo que los errores de procedimiento y la ausencia de restauración coronal se asociaron con una frecuencia significativamente mayor de lesiones de la PA.
