“…The remaining 6 studies were basic research studies with histological assessment as the reference standard (Table 1). Three were undertaken on extracted teeth, [34][35][36] 2 on dry mandibles, 37,38 and 1 on cadavers. 39 Regarding outcomes, the mean difference was calculated in 3 studies, whereas the mean absolute difference was calculated in the other 3 studies (Table 2).…”

Purpose: This study was performed to assess the accuracy of preoperative cone-beam computed tomography (CBCT), when justified for other reasons, in locating the apical foramen and establishing the working length. Materials and Methods: Six electronic databases were searched for studies on this subject. All studies, of any type, were included if they compared measurements of working length with preoperative CBCT to measurements using an electronic apex locator (EAL) or histological reference standard. Due to the high levels of heterogeneity, an inverse-variance random-effects model was chosen, and weighted mean differences were obtained with 95% confidence intervals and P values. Results: Nine studies were included. Compared to a histological reference standard, CBCT indicated that the apical foramen was on average 0.40 mm coronal of its histological position, with a mean absolute difference of 0.48 mm. Comparisons were also performed to an EAL reference standard, but the conclusions could not be considered robust due to high levels of heterogeneity in the results. Conclusion: A low level of evidence is produced suggesting that preoperative CBCT shows the apical foramen to be on average 0.40 mm coronal to its histological position, with a mean absolute difference of 0.48 mm.

“…The inspection of the third dimension of the root canal helps to increase the accuracy of working length estimation. Therefore, measurements of root canals on existing CBCT images are a relatively new method for the con rmation of the diagnostic working length, which has been studied by numerous researchers [22,23]. However, the CBCT scan not recommended to be used routinely in endodontic practice because of dose considerations and potential radiation risks [24,25].…”

“…Conventional 2-dimensional (2D) radiographs provide a cost-effective, high-resolution image, which continues to be the most popular method of imaging today. However, intraoral radiography has some limitations because of its 2-dimensional nature, information may be di cult to interpret, especially in challenging conditions when the anatomy and background pattern are complex [1,2].…”

“…CBCT has been considered useful in endodontics as it can provide 3-dimentional images (3D) for the detection and visualization of the number and location of roots and canals, identi cation of unidenti ed root canals [13,14]. The additional information provided by CBCT may improve the diagnostic accuracy and con dence in decision-making as well as have an impact on treatment planning [1]. Cone-beam computed tomography overcomes several limitations of conventional radiography.…”

Background: An accurate estimation of the working canal length is essential for successful root canal treatment. This study aimed to investigate the diagnostic accuracy of root canal length estimation on cone-beam computed tomography (CBCT) scans and digital paralleling radiographs (PAs), using the real canal length as a gold standard, and to evaluate the influence of canal curvature on this estimation. Methods: Sixty extracted human premolar teeth selected for this study. Root canal length measurement performed on CBCT scans (NewTom, Giano, Verona, Italy) and digital paralleling radiography (EzRay Air W; Vatech, Korea). The real working length established by subtracting 0.5 mm from the actual canal length. Results: No significant difference was found between CBCT and digital paralleling radiography. There was a tendency for underestimation of the root canal length measured on the CBCT images in 52 (86.7%) of the examined teeth and overestimated it in 5 teeth (8.3%). All the digital radiographs slightly overestimated the real canal length. The analysis revealed a strong correlation between the estimation from moderate to severe curvature for digital radiography, and CBCT images. Conclusion: Preoperative working length estimation can be made closest to its real clinical canal length on the standardized paralleling technique, using a long (16-inch) target–receptor distance.

“…El uso de Cone Beam (CBCT) da la posibilidad de determinar LT de manera preoperatoria para obtener información anatómica de manera confiable en formato 3D (Aktan et al, 2016;Janner et al, 2011;Liang et al, 2013). A pesar de la gran ventaja que ofrece el CBCT para la endodoncia, hasta hoy no existe un consenso en la literatura sobre la precisión de medir LT con este sistema, en comparación con LEF y/o con método radiográfico (Método de Ingle) (Liang et al;Sherrard et al, 2010).…”

RESUMEN: En la historia de la Endodoncia, se han utilizado distintos métodos para determinar la longitud de los canales radiculares, como sensación táctil y radiografías. Últimamente, han adquirido gran importancia los localizadores apicales electrónicos, por su gran precisión. Actualmente se ha incorporado el uso de imagenología con Cone Beam. Debido a que existen muchas formas de medir dicha longitud, es necesario ponerlos a prueba y ver si se asemejan a la técnica gold estándar definida en la literatura como el localizador electrónico de foramen apical. El propósito de esta investigación es determinar si existen diferencias estadísticamente significativas en la medida de la longitud de trabajo entre el localizador electrónico de foramen apical, y el uso de Cone Beam procesado con el software 3D endo de Dentsply Sirona. Para esto, se seleccionaron 30 premolares extraídos; se les tomó un Cone Beam para ser analizados con el software 3D endo y medir la longitud de trabajo. Una vez hecho esto, se realizó manualmente cavidad de acceso y se preparó el tercio cervical con fresas Gates Glidden 1 y 2; luego, los dientes fueron colocados en un modelo Pro Train, que asemejó las propiedades de los dientes en la cavidad oral, para permitir el uso del localizador electrónico de foramen y determinar la longitud de trabajo. Una vez obtenidos los datos, fueron comparados a través del Test de Proporciones (p=0.05 hipotético), dando como resultado p=0,2 lo que indica que no existen diferencias estadísticamente significativas en la medida de la longitud de trabajo entre ambos métodos.
