Abstract: Prevalence of dens evaginatus (DE) is very rare in molars, with only nine previous cases described, and all involving patients of Asian heritage. This article presents two unique cases of molar DE in European patients of 10 and 5 years of age, and a review of the current literature. The aim of the article is to review the aetiology, diagnosis, clinical significance and management of teeth affected with DE.

Clinical relevance: Dens evaginatus describe teeth with supplemental cusps that may contain pulpal tissue. These are susceptible to wear, fracture and caries. This may lead to pain and pulpal necrosis. Early diagnosis and management are key to prevent symptoms and optimize tooth prognosis
