dc.descriptionIntroducción: La existencia de variaciones anatómicas ocasionan fracasos en tratamientos endodónticos, por lo que es importante diagnosticarlas. El objetivo fue determinar la reproducibilidad y la validez de criterio de las radiografías con placa de fósforo y la radiovisiografía con sensor para identificar las variaciones anatómicas detectadas por tomografía computarizada de haz cónico (CBCT) en premolares inferiores. Métodos: En 140 premolares se obtuvieron imágenes por CBCT, radiografía y radiovisografía. Se realizó lectura independiente por dos endodoncistas, evaluándose la clasificación de Vertucci y las ramificaciones. Se determinó la reproducibilidad intraobservador e interobservador. Se calcularon sensibilidad, especificidad y áreas bajo la curva operador-receptor (AUC) utilizando como estándar de oro la CBCT. Resultados: La reproducibilidad intraobservador e interobservador fue mayor para radiografía. Para la Clase I de Vertucci, la radiografía presentó mayor sensibilidad (94,7%), especificidad (64,9%) y AUC (0,7952) que la radiovisiografía (89,3%, 62,2% y 0,7574, respectivamente), al igual que para la Clase V (Radiografía 69,2%, 93% y 0,8111; radiovisiografía 50%, 84,2% y 0,6711, respectivamente). Ninguna de las técnicas aportó al diagnóstico de la Clase III (AUC <0,5). Las ramificaciones fueron infrecuentes (2,9%) y su detección fue baja (Sensibilidad 25% para radiografía y 0% para radiovisiografía). Discusión: Este es el primer estudio que evalúa la reproducibilidad y validez de estas dos técnicas radiográficas comparadas con la CBCT para la detección de variaciones anatómicas en dientes. Conclusiones: La radiografía con placa de fósforo presentó mayor reproducibilidad y validez para el diagnóstico de las Clase I y V de Vertucci, que fueron las variaciones más frecuentes.spa
dc.description.abstractIntroduction: The existence of anatomical variations cause failures in endodontic treatments, so it is important to diagnose them. The objective was to determine the reproducibility and criterion validity of phosphor plate radiographs and sensor radiovisiography to identify anatomical variations detected by cone-beam computed tomography (CBCT) in lower premolars. Methods: 140 CBCT, radiographs and radiovisography premolar images were taken. Independent interpretations by two Endodontists were carried out to evaluate the Vertucci classification and teeth ramifications. Intra-observer and interobserver reproducibility were determined. Sensitivity, specificity and areas under the operator-receptor curve (AUC) were calculated using CBCT as the gold standard. Results: The intra-observer and interobserver reproducibility of the radiography was higher than the radiovisiography. For Vertucci Class I, radiography had higher sensitivity (94.7%), specificity (64.9%) and AUC (0.7952) than radiovisiography (89.3%, 62.2% and 0.7574, respectively), similarly in Class V (Radiography 69.2%, 93% and 0.8111; radiovisiography 50%, 84.2% and 0.6711, respectively). None of the techniques contributed to the diagnosis of Class III (AUC <0.5). Ramifications were infrequent (2.9%) and their detection was low (Sensitivity 25% for radiography and 0% for radiovisiography). Discussion: This is the first study thar evaluates the reproducibility and validity of these two radiographic techniques compared to CBCT for the detection of anatomical variations in teeth. Conclusions: Phosphor plate radiography showed higher reproducibility and validity for the diagnosis of Vertucci Class I and V, that were the most frequent observed premolar variations.spa
