“…This disadvantage is overcome by the use of a microscopic technique that allows observation under different magnifications of teeth ex vivo, either by a direct visualization of the apex, or by analyzing a sagittal or cross-sectional cut in order to visualize the entire length of the apical anatomy. This is a simple and reproducible method to study apical anatomy (Martos et al, 2009;Abarca et al, 2014).…”

SUMMARY:The purpose of this study was to determine the shape and diameter of the physiological foramen in maxillary premolars of a Chilean population. The sample consisted of 125 extracted maxillary premolars, in which the apical three to five millimeters were cut and observed under magnification of 40x, photographed (Motic Cam), and analyzed using Motic Images Plus 2.0 ML in order to obtain measurements of the minor and major diameter of each physiological foramen. The average minor and major diameter in maxillary premolars was 0.270 and 0.413 mm, respectively. In terms of shape, 72.19 % had oval shaped physiological foramen; 18.93 % were irregularly shaped and 8.88 % were round. Oval and irregular canals are significantly more difficult to shape and require special attention in order to obtain a thoroughly disinfected root canal system.

“…1 Morphologic analyses have shown that canals are oval-shaped or irregular in the apical third and present their largest diameter at the buccolingual aspect. 2,3,4 This concept is confirmed by the fact that the first file that clinically binds to the apex is smaller than the anatomical diameter of the apical foramen. 5 Weine 6 (1989) proposed that the apical enlargement must be three sizes larger than the first file that bound at the working length.…”

In this study, scanning electron microscopy (SEM) was used to evaluate the adaptation of the first apical file after preflaring in mesiobuccal (MB) and mesiolingual (ML) canals of mandibular molars considering the tactile sensibility as a reference. The mesial canals (n = 22) of human mandibular molar teeth were used, and the first instrument to bind to the working length was determined after preflaring and crowndown shaping. Digital images of the root apex were acquired and a single examiner determined the contact of the file with the walls using Image J software. The results showed that the file was in contact in 47.83% and 31.71% in the MB and ML canals, respectively. When the apexes are fused, the average was 40.03%. A descriptive analysis showed that the first apical file did not touch all dentin walls in any of the samples.

“…La mayoría de autores acotan que el foramen apical se encuentra 1 mm coronal al ápice anatómico [6][7][8] ; sin embargo, otros autores como Martos y cols. 9 plantean que esta distancia es menor a 1 mm, Marroquin y cols. 10 acotan una distancia entre 0,86 mm y 1 mm en molares inferiores y superiores; y Blaskovic y cols.…”

Materiales y método: Estudio in vitro que incluyó 71 piezas dentarias (incisivos, caninos y premolares) uniradiculares. Se evaluó la posición del foramen apical (vestibular, palatino/lingual, mesial y distal) así como la distancia desde el foramen apical hasta el vértice del ápice anatómico a través de un Vernier electrónico. Resultados: Treinta y dos piezas dentarias (45,1%) coincidieron la ubicación entre el foramen apical y ápice anatómico; el 56,4% de forámenes apicales se encontró a nivel vestibular y palatino/lingual. De las piezas dentarias donde se encontró la coincidencia, la mayor cantidad fue encontrada a nivel de los incisivos centrales superiores (31,3%). La distancia entre la ubicación del foramen apical y el ápice anatómico fue de 0,36±0,41 mm. Conclusiones: El foramen apical se ubicó en mayor frecuencia a nivel vestibular y palatino/lingual. La coincidencia entre la posición del foramen apical y el vértice del ápice anatómico se encontró presente en un 45% de casos.

AbstractObjective: To evaluate the relationship between the position of the apical foramen and the anatomic apex in uniradicular teeth. Materials and method: In this vitro study that included 71 teeth between incisors, canines and premolars, all of them were uniradicular. The position of the apical foramen (vestibular, palatal / lingual, mesial and distal) was evaluated as well as the distance from the apical foramen to the apex of the anatomic apex through an electronic Vernier. Results: In thirty-two dental pieces (45.1%) coincided the location between the apical foramen and anatomical apex; in 40 (56.4% ) the apical foramen was found at vestibular and palatal / lingual levels, In teeth where there was concordance, the largest amount was found at the level of the upper central incisors (31.3%). The distance between the position of the apical foramen and the anatomical apex was 0.36±0.41 mm. Conclusions: The apical foramen is more ...

Topographical evaluation of the major apical foramen in permanent human teeth

Abstract: In this sample of teeth without apical resorption the distance between the major foramen and the anatomical root apex was always <1 mm. Deviation of the major foramen from the anatomic apex varied widely amongst tooth groups.
