Summary: Intimate knowledge of root canal morphology is essential for succesful endodontic therapy. The objective of this project was to develop a technique, utilizing computer image processing that would allow three-dimensional reconstruction of the root and its root canal. The samples were permanent lower first molars and incisives. The cross-sectioning started at the root apex and continued in the coronal direction, rougly perpendicular to the long axis of the root. The distance between two cuts was registered. After each section the root canal contour was determined utilising the calibrated net with coordinate system in the ocular of the stereomicroscope. The determined coordinates were relevant input data for the reconstruction of root canal cross-sections, longitudinal sections and for the final three-dimensional root canal model.

Keywords: root canal anatomy, apical constriction, apical foramen, root apex

Research goals: The intracanal biomechanical preparation as well as root fillingshould terminate at cementodental junction or apicalconstriction. The objective of this project is to determinetopography and anatomy of the apical constriction. The method oftooth decalcification cannot serve for accurate exploration. Thenew technique had to be developed for the researching internalroot morphology. The objectives were the following: 1. To developa technique utilizing computer image processing that would allowthree-dimensional imaging of root canals. 2. To analyse the rootcanal cross-sections. 3. To determine the smallest root canalcross-section. 4. To reconstruct the longitudinal root canalsection and to describe its image. 5. To confirm the presence ofthe apical constriction.
