It consists of enamel covering a dentinal core that usually contains pulp tissue. The presence of pulp within the cusp-like tubercle has clinical significance and distinguishes it from supplemental cusps, such as cusp of carabelli.1 Early detection and management of this condition is important because trauma during mastication causes fracture or wear of the tubercle that leads to necrosis of pulp and periapical infection. This condition is predominantly found on the occlusal surface of mandibular premolars2, lingual surface of anterior teeth (mainly maxillary lateral incisors).3 Prevalence of DE studied in several population ranges from 1% to 4%,4 the prevalence was found to approximately 2% of Asian descent population.5 Higher rates of occurrence were reported among the Chinese population. 1.29%–3.6%.6 It is usually observed as bilateral, symmetric distribution, with a slight sexual predilection for
