“…Otro estudio demostró que CBCT detectó lesiones periapicales en 37 raíces (25,9 %), en comparación con 18 (12,6 %) de las radiografías periapicales (Liang et al, 2011). Estrela et al (2008) evaluaron la precisión diagnóstica de lesiones apicales en radiografías panorámicas y periapicales en comparación a CBCT, reportando los valores de sensibilidad, especificidad, valores predictivos positivos y negativo; se evaluaron a 888 pacientes (1508 dientes) concluyendo que las radiografías periapicales tienen un alto valor predictivo positivo, sin embargo, presentan un bajo valor predictivo negativo, es decir, en un 55 % de las radiografías periapicales corresponden a situaciones donde realmente no hay lesiones.…”

HERNÁNDEZ, V. S.; DONOSO, Z. M.; SANHUEZA, T. C.; LINCO, O. J. & RIQUELME, C. S. Evaluación de lesiones periapicales en pacientes derivados a cirugía periapical mediante tomografía computarizada de haz cónico. Int. J. Odontostomat., 11(2):128-132, 2017. RESUMEN:El uso de la tomografía computarizada de haz cónico (CBCT) en endodoncia ha ido en aumento, justificando su uso en casos más complejos, como cirugías periapicales. El objetivo fue evaluar las características imagenológicas encontradas en un grupo de pacientes derivados a cirugía periapical, mediante el uso de CBCT. Se realizó un estudio observacional descriptivo, en un grupo de pacientes, derivados a cirugía periapical, a los cuales se realizó un examen de CBCT, evaluación clínica y radiografía periapical. Un total de 18 pacientes fueron examinados (6 hombres y 12 mujeres), cuyas edades estaban entre los 19 y 64 años de edad. El diámetro mayor de las lesiones varió entre 6 mm a 16 mm. El uso de CBCT en cirugías periapicales entrega información más completa al cirujano, ya que permite mayor precisión al realizar el acceso quirúrgico y detecta un mayor número de lesiones periapicales que con la radiografía periapical, logrando en casos complejos un mejor diagnóstico y planificación del tratamiento.PALABRAS CLAVE: tomografía computarizada de haz cónico, cirugía periapical, endodoncia.

BACKGROUNDRadiographic imaging is a preliminary and essential step in the diagnosis, treatment planning and followup of all the cases in endodontics. The interpretation of an image can be influenced by several confounding factors including the regional anatomy a nd superimposition of both teeth and the surrounding dentoalveolar structures. Due to the complexity of the maxillofacial skeleton, conventional two dimensional (2-D) radiographic images fail to provide accurate information of the particular region of interest. Superimposition of the images, seen in planar periapical radiography, reveal only limited information about a three dimensional (3-D) object. The structures so visualised are also subject to geometric distortion. Hence, recent research has highlighted the need for 3-D imaging modality to overcome the potential drawbacks of conventional radiography. Medical Computed tomography (CT) was one of the earliest three dimensional imaging systems. It has been used in the field of endodontics over the past decade but with limited success. This can be ascribed to high radiation exposure, lengthy scan time and cost factor. The next new phase in imaging modalities came with the advent of cone beam computed tomography (CBCT). Contemporary endodontics emphasise on the significance of CBCT, since it limits the radiation exposure and rapidly provides 3D reconstructed images which have been proven to be accurate in all aspects. This paper reviews the importance of three dimensional CBCT technology over conventional two dimensional imaging system along with its potential drawbacks. BACKGROUND Diagnostic imaging is considered as an important adjunct in clinical assessment of the patient. Since time immemorial, radiology has played a critical role in dentistry and now with expanding array of different imaging modalities, it has become an indispensable tool in endodontic assessment as well. The first intraoral radiograph to be used in dentistry was reported by Sir C Edmond Kells. 1 Thereafter, field of radiology has seen several changes. With improvements in the film technology and reduced exposure times, gradually film based system gave way to advanced sensor based digital systems. Solid state sensors like charge coupled device (CCD), complementary metal oxide semiconductor (CMOS) and photostimulable phosphor plates (PSP) largely replaced the film based conventional imaging. 2, 3, 4 Digital systems also provided opportunities for image processing and modification (colour, brightness, contrast) which further assisted the diagnostic process. But the images were still a two dimensional representation of three dimensional anatomy and the need for cross sectional information was still unmet.

Cone beam computed tomography (CBCT) is a contemporary, radiological imaging system designed specifically for use on the maxillofacial skeleton. The system overcomes many of the limitations of conventional radiography by producing undistorted, three-dimensional images of the area under examination. These properties make this form of imaging particularly suitable for use in endodontics. The clinician can obtain an enhanced appreciation of the anatomy being assessed, leading to an improvement in the detection of endodontic disease and resulting in more effective treatment planning. In addition, CBCT operates with a significantly lower effective radiation dose when compared with conventional computed tomography (CT). The purpose of this paper is to review the current literature relating to the limitations and potential applications of CBCT in endodontic practice.
