‘Dens invaginatus’ (DI) is a developmental anomaly of teeth, where an infolding of the enamel occurs into the dentine, creating a pocket or a dead space, as a result of the invagination of the enamel organ into the dental papilla prior to calcification. DI have been reported in 0.3–10% of the population. This case describes the comprehensive management of a 9-year-old child with multiple dens invaginatus.
‘Dens invaginatus’ (DI) is a developmental anomaly of teeth, in which an infolding of the enamel occurs into the dentine, creating a pocket or a dead space, as a result of the invagination of the enamel organ into the dental papilla prior to calcification.1,2
DI can be classified depending on the degree of enamel infolding. The most widely accepted classification (Table 1) was developed by Oehlers in 1957.3 Several other terms such as ‘dens in dente’, ‘dilated composite odontome’, and ‘gestant anomaly’ also have been used in the literature to describe this condition.2 DI has been reported in 0.3–10% of the population.1
The most affected teeth are the maxillary lateral incisors, maxillary central incisors, and rarely the premolar and canine teeth.4 It may affect the mandibular teeth, deciduous teeth and supernumerary teeth.4 In 43% of cases, DI has occurred bilaterally implying the necessity to assess the contralateral tooth.5
