Summary: Deviation of the major apical foramen from the anatomical root apex is a recognized phenomenon. to determine the frequency, position and mean distance of the major apical foramen from the anatomical root apex, 230 roots of permanent teeth were examined stereomicroscopically and radiographically. Radiographic analysis was used to establish how accurate the conventional radiograph was in displaying such a deviation. The frequency of deviation of the major foramen, determined stereomicroscopically, was 76% and depended on the type of teeth examined. Radiographic analysis of the same sample revealed 57% of root canals had asymmetry of the root canal foramen. Agreement of stereomicroscopic and radiographic findings was found to be 61%. The most frequent deviation of the major foramen was on the distal root surface (29%), but this was not statistically significant. The mean distance between the deviation of the major foramen and the anatomical root apex was 0.99 mm. The study indicates that the clinician should consider deviation of the foramen during root canal treatment, as the deviation could not easily be detected radiographically.

Summary: The objective of this research was to develop a technique that would allow three-dimensional imaging of root canals utilizing computer image processing. Ten single-rooted permanent human teeth with mature apices were analysed. The teeth were decoronated and fixed on boards with the long axis of the root perpendicular to the board. The cross-sectioning started at the root apex and continued in the coronal direction, roughly perpendicular to the long axis of the root. The samples were devided into two groups. The first five samples were sectioned 15 times, each section being 0.5-mm thick, in order to obtain the three.dimensional reconstruction of the root and the root canal. The second group of five samples served for the graphical reconstruction of the apical portion of the root canal. The root apex of each sample was cross.sectioned 19 times and each section was 0.2-mm thick. After each section the root canal contour was defined utilizing the calibrated net with coordinate system in the ocular of the stereomicroscope. The coordinates of the root canal cross-section contour this determined, together with the value of the hickness of each cut, were relevant input data for the reconstruction of the root canal cross-sections, longitudinal sections and for the final three-dimensional rebuild of the root and the root canal model. This technique appears to be highly accurate in determining the anatomy of the root canal system and may also be applied in other fields of dental research.

Summary: The apical foramen is the most apical point of the root canal, and the region of contact between the root canal system and the vital tissue beyond. It should be the main point of concern in root canal therapy, because on of the most common reasons for endodontic failure is an inadequate seal of the apical foramen. The objective of the present study was to determine the shapes of the major roort canal opening. Two hundred and sixty major apical foramina were examined. Observations were carried out using a stereomicroscope (Carl Zeiss, Jena, Germany) at x15 magnification. During the examination the following shapes were obseerved: circle, ellipse, teardrop, figure of eight and irregular forms. The apical foramen most frequently had a circular shape, in 5.8% of the main root canal openings. The elliptical contour presented in 22.7% of samples, the teardrop shape in 10.4% and the figure of eight shape occurred in 5% of samples. Statistical analysis revealed that the circular shape of the apical foramen was the most frequent finding (P<0.01).

Summary: Intimate knowledge of root canal morphology is essential to successful endodontic therapy. The objective of this pilot study was to develop a technique, utilizing computer image processing that would allow three-dimensional imaging of root canals. Ten single-rooted permanent human teeth with mature apices were analysed. The teeth were decoronated, fixed on boards with the long axis of the root perpendicular to the board. The cross-sectionong started at the root apex and continued in the coronal direction, roughly perpendicular to the long axis of the root. It was important to register the distance between the previous and following section. After each section the root canal contour was determined utilising the celibrated net with co-ordinate system in the ocular of the stereomicroscope (Carl Zeiss, Jena, Germany). The determined co-ordinates were relevant input data for the reconstruction of root canal cross-sections, longitudinal sections and for the final three-dimensional root canal model. Overall, this technique appeared to be very accurate in determining the anatomy of the root canal system. This technique could possibly be applied to other fields of dental research.
