Dental evagination (dens evaginatus) of the second premolar in the upper jaw. Clinical case

Abstract

Dens evaginatus (DE) is an odontogenic developmental abnormality that can be defined as a tubercle or bulge on the surface of a tooth, consisting of the outer layer of enamel, dentin, and possibly pulp. Early diagnosis and treatment of dental evagination is important to prevent untimely endodontic treatment, occlusal trauma, aesthetics, and the development of fissure caries. This pathology of tooth development is usually found on the premolars of the lower jaw as an additional tubercle or bulge between the buccal and lingual tubercles. DE in the maxillary premolar has been reported rarely in the literature. We report one such rare case in the maxillary premolar.Material and methods. The article describes a clinical case of treating a patient with dental evagination. For observation, we used X-ray images made with CBCT, as well as a photo protocol of the stages of patient treatment.Conclusions. Since this pathology is rare, the description of this clinical case will help doctors better understand the approaches to dental treatment with such anomalies in the development of tooth tissues.
