Mild attrition was present with mandibular molars (Figures 1(a), 1(b), and 1(c)). Suspecting the congenital absence of permanent teeth, panoramic radiograph was taken which confirmed congenital absence of all permanent teeth that clinically were not present (Figure 1(d)). Intraoral periapical radiograph was taken in relation to 11 and 21 which revealed the presence of Oehlers type II dens in dente (dens invaginatus) with the central incisors (Figure 1(e)).

Generalized microdontia with spacing in the permanent dentition was appreciable (Figures 2(a), 2(b), and 2(c)). Panoramic radiograph disclosed congenital absence of all permanent teeth that were missing on clinical examination with generalized spacing (Figure 2(d)). On periapical radiography, Oehlers type I dens in dente was seen in relation to all maxillary incisors (Figure 2(e)).

Shovel-shaped crown morphology was appreciable with 21, with associated deep lingual pit (Figures 3(a) and 3(b)). Panoramic radiography confirmed the congenital absence of following permanent teeth: 13, 12, 22, and 23 (Figure 3(c)). Oehlers Type I dens in dente was detected with 21 on periapical radiograph (Figure 3(d)).
