“…These studies differ in establishing the reference point from which measurement accuracy is determined. Some authors measured from the minor diameter (apical constriction) (21,22,(27)(28)(29)(30)(31)(32)(33), whereas others measured from the major diameter or apical foramen (16,23,34). EALs have traditionally afforded some latitude of acceptable error in locating the apex (21,25,26,30).…”

“…Guise et al determinaron que sí hubo diferencias significativas en el porcentaje de éxito de las mediciones entre el ELE y el PAL comparándolos con el Root ZX, sin embargo no hubo diferencias entre el PAL y el ELE. Se determinó la longitud de trabajo tal y como los sugieren los fabricantes: utilizando el localizador para determinar foramen apical y restando 0.5mm y de esta forma el Root ZX obtuvo un acierto del 97.5% y en los casos de error se mostró corto en relación a la medición mientras que el ELE y el PAL tuvieron un éxito del 90% y 95% respectivamente y al fallar lo hicieron mostrando mediciones sobre-extendidas (12). Estos resultados respecto al éxito del Root ZX (12) se confirman con otra investiagción.…”

RESUMENEn la actualidad es cada vez más la aceptación y confiabilidad que tienen los localizadores apicales en las consultas endodónticas, ya que cada vez logran mediciones más exactas de la longitud de trabajo al localizar no solamente la constricción apical sino que también determina la salida del foramen apical y, por ende se puede predecir más certeramente el resultado de la terapia endodóntica; todo esto gracias a un largo período de desarrollo y perfeccionamiento de estos aparatos desde mediados del siglo pasado, así como también suficientes estudios que avalan resultados positivos y confiables. La endodoncia moderna no puede ni debe dejar de lado el uso los localizadores de ápice ya que como hemos mencionado es una herramienta fundamental no solo en la determinación de la longitud de trabajo sino también en el diagnóstico de perforaciones y fracturas. Sin embargo, así como tiene sus ventajas también tiene sus desventajas, las cuales hay que tener presentes al momento de utilizar estos aparatos, sin olvidar tampoco seguir al pie de la letra las indicaciones del fabricante y mantenerse actualizado respecto a los usos, indicaciones y contradicciones que arrojen estudios recientes. PALABRAS CLAVELocalizador de apice, Longitud de trabajo, Constricción apical. ABSTRACTNow days is more the trust we can have to the Apex-locator in endodontics. Now we can expect more accuracy results working length measure, not only of the apical constriction but the total length of the roots. Endodontics can't left behind the use of the Apex-locator, because of its useful work, not only on the determination of the works length, also in the diagnostic of perforations or fractures. Even do, this article displays a reliable and simple guide in the use of apex locator during enodontic treatment.

“…Some researchers consider the minor diameter or apical constriction (15), whereas others consider the major diameter or apical foramen (14) for this purpose. Variations in the apical third permit a maximum apical limit of 1 mm coronal to the major foramen for endodontic therapy (5,23).…”

“…Several studies have investigated the use of the EALs, their accuracy in endodontic treatment (12)(13)(14)(15)(16) and retreatment (17), the influence of prior preflaring (18), and their coefficient of repeatability (13).…”

An in vivo radiographic evaluation of the accuracy of Apex and iPex electronic Apex locators

et al. 2012

The aim of this study was to evaluate in vivo the clinical applicability of two electronic apex locators (EALs) - Apex (Septodont) and iPex (NSK) - in different groups of human teeth by using radiography. The working lengths (WLs) of 100 root canals were determined electronically. The EAL to be used first was chosen randomly and a K-file was inserted into the root canal until the EAL display indicated the location of the apical constriction (0 mm). The K-file was fixed to the tooth and a periapical radiograph was taken using a radiographic film holder. The K-file was removed and the WL was measured. The same procedure was repeated using the other EAL. Radiographs were examined with the aid of a light-box with lens of ×4 magnification by two blinded experienced endodontists. The distance between the file tip and the root apex was recorded as follows: (A) +1 to 0 mm, (B) -0.1 to 0.5 mm, (C) -0.6 to 1 mm, (D) -1.1 to 1.5 mm, and (E) -1.6 mm or greater. For statistical purposes, these scores were divided into 2 subgroups according to the radiographic apex: acceptable (B, C, and D) and non-acceptable (A and E). Statistically significant differences were not found between the results of Apex and iPex in terms of acceptable and non-acceptable measurements (p>0.05) or in terms of the distance recorded from file tip and the radiographic apex (p>0.05). Apex and iPex EALs provided reliable measurements for WL determination for endodontic therapy.
