Dens evaginatus is a rare odontogenic developmental anomaly that is found in teeth where the outer surface appears to form an extra bump or cusp.

Premolars are more likely to be affected than any other tooth.^[3] It could occur unilaterally or bilaterally. ^[1] Dens evaginatus (DE) typically occurs bilaterally and symmetrically.^[4] This may be seen more frequently in Asians^[3] (including Chinese, Malay, Thai, Japanese, Filipino and Indian populations).^[4]

The prevalence of DE ranges from 0.06% to 7.7% depending on the race.^[3] It is more common in men than in women,^[3] more frequent in the mandibular teeth than the maxillary teeth.^[1] Patients with Ellis-van Creveld syndrome, incontinentia pigmenti achromians, Mohr syndrome, Rubinstein-Taybi syndrome and Sturge Weber syndrome are at a higher risk of having DE.^[3]^[2]
