 Three types of dens invaginatus occur which can be detected on radiography:Type I: invagination ends in a blind sac, limited to the tooth crown (Figure 1.10a)Type II: invagination extends to the cementoenamel junction extending in a blind sac. It may or may not extend into the root pulpType III: invagination extends to the interior of the root providing an opening to the periodontium, sometimes this presents another foramen in the apical region of toothDens evaginatus shows a tubercle on the occlusal surface (Figure 1.10b)
