Background: Successful endodontic treatment requires effective biomechanical preparation of the root canals and three-dimensional obturation of the root canal system. This can be achieved only by knowing and identifying the variations in the root canal system of the endodontically treated teeth.
The Aim: The aim of this article is to present cases of endodontic treatment of maxillary first premolar with three root canals – different types.
Material and Methods: Five clinical cases of successful endodontic treatment of patients with maxillary first premolar and three root canals are described.
Result and Discussion: It is noted that good endodontic practice requires good knowledge of dental anatomy and possible variations, accurate X-ray images, as well as use of magnifying equipment.
Conclusion: Knowledge of dental anatomy is fundamental for good endodontic practice.

Key words: Root canal anatomy, three roots, three canals, maxillary first premolar,
