Intraoral examination revealed depapillation of the tongue and an erythematous lesion present on the buccal mucosa bilaterally, extending posteriorly from the angle of the mouth, suggestive of angular stomatitis and oral candidiasis (Figs 3A and B). The patient presented with adult dentition, and on examination, the maxillary lateral incisors were observed to be malformed (Fig. 3C). Generalized spacing was noted, which could be attributed to the smaller, narrower size of the affected teeth (Figs 3D and E). Radiographic findings revealed short, blunted, conical roots, impacted left maxillary canine, and taurodontism of the maxillary and mandibular molars (Fig. 3F).
