Supernumerary cusps are morphological variations classified into three patterns: Carabelli\'s cusp, dens evaginatus (DE), and talon cusps. DE is a disturbance of tooth formation that appears as an accessory tuberculated cusp composed of enamel, dentin, and pulp tissue. The first permanent molars (FPMs) may show alteration in their shape or structure. However, the alteration could be observed as accessory cusps on the occlusal surface or accessory roots or hypomineralization as molar incisor hypomineralization. DE is a rare dental anomaly that can occur in primary or permanent dentitions. It is infrequently seen on anterior teeth or premolars. However, their occurrence on molars is rarer. This presented a rare case of bilateral double supernumerary cusps on the right and the left maxillary FPMs of a 6-year-old Libyan boy, while the mandibular FPMs appeared with normal cusps. The aims of this study were to report and discuss the diagnostic methods and the management of this anomaly. In addition, shed light on the importance of early diagnosis and follow-up observation. That could help in reducing the potential dental problems and to improve patients’ quality of life.
