Abstract

The aim of the study was to investigate the number and diameter of the Cebus apella dentinal tubules. The roots of the Cebus apella teeth were examined in specific tooth locations: the apical, middle and cervical dentin. The calculations were based on the scanning electron microscope photographs of the fractured surfaces. The results showed that the average number of dentinal tubules for each location was: 74,800 tubules/mm2 for apical root dentin, 90,000 tubules/mm2 for mid-root dentin, 91,600 tubules/mm2 for cervical root dentin. The average diameter was the following: apical root dentin, 4,30µm; mid-root dentin, 4,37µm; cervical root dentin,  5,23µm. These findings demonstrate that the Cebus apella teeth are a suitable substitute for human in endodontics studies. 
KEY WORDS: Dentin, dentinal tubules, teeth.
