La capacidad de reconocer las variaciones anatómicas del sistema de conductos radiculares es crucial antes de iniciar el tratamiento endodóntico. No menos importante es llevar a cabo estos tratamientos con base en la evidencia científica actual. Los premolares son las piezas dentales con mayor complejidad en su anatomía interna y las que se presentan en mayor porcentaje en comparación con otras piezas dentarias; si una pieza presenta anatomía accesoria, es altamente probable que la pieza contralateral presente la misma anatomía interna, a esto se le conoce como bilateralidad simétrica. Por lo tanto, las tomas radiográficas deberán ser ejecutadas con proyecciones proximales y ortorradiales para aproximarnos a la forma 3D que presentan estas anatomías y minimizar errores procedimentales. El uso de la magnificación es imprescindible para abordar todo el sistema de conductos y realizar un adecuado tratamiento endodóntico. El presente reporte de caso muestra el abordaje de los dos primeros premolares superiores maxilares de un mismo paciente con anatomía de tres conductos y simetría bilateral.
The ability to recognize the anatomical variations of the root canal system is crucial before starting endodontic treatment, no less important is being able to carry out these treatments based on current scientific evidence. The premolars are the dental pieces with the greatest complexity in their internal anatomy and the ones that appear in the highest percentage compared to other teeth, if a piece presents accessory anatomy, it is highly probable that the contralateral piece presents the same internal anatomy, to this it is known as symmetrical bilaterality, therefore the radiographic images must be executed with proximal and orthoradial projections in order to approximate the 3D shape that these anatomies present and minimize procedural errors. The use of magnification is essential to be able to address the entire root canal system and perform an adequate endodontic treatment. This case report presents the approach to 2 maxillary first premolars from the same patient with 3-canal anatomy, presenting bilateral symmetry.
