Abstract


The anatomy of root canals is very variable, with the presence of ramifications, side canals, accessory canals, and interconnections. Therefore, the knowledge of the internal tooth morphology has a fundamental importance for the localization and treatment of root canals, thus achieving success in endodontic treatment. In Endodontics, the preclinical teaching requires human teeth, but because of the current difficulty in obtaining them, the students have used artificial dental
elements. Objective: This study aimed to evaluate the anatomy of the pulp chamber of artificial teeth, used in practical activities in Endodontics. Material and methods: Therefore, the artificial teeth were X-rayed through the digital system and the internal anatomy of the pulp chamber was measured through the Image Tool software. Results: The height of the mandibular pulp chamber: mandibular molar = 1.8 mm and maxillary molar = 1.32 mm; distance from the furcation to the pulp chamber floor: mandibular molar = 5.89 mm and maxillary molar = 7.24 mm; distance from the furcation to the pulp chamber’s roof: mandibular molar = 7.61 mm and maxillary molar = 8.59 mm; distance from the tip of the buccal cusps to the furcation: mandibular molar = 14 mm and maxillary molar = 15 mm; distance from the tip of the buccal cusps to
the pulp chamber’s floor: mandibular molar = 7.9 mm and maxillary molar = 8.1 mm; distance from the tip of the buccal cusps to the pulp chamber’s roof: mandibular molar = 6.2 mm and maxillary molar = 6.4 mm. The measures were homogeneous with maximum percentage variation of 26.5%. Also, the artificial teeth were similar to natural teeth, except for the relationship between the pulp chamber’s roof and cementum-enamel junction. Thus, it is recommended the use artificial teeth with caution in preclinical teaching of Endodo ntics.
