Multiple bilateral dens in dente as a factor in the etiology of multiple periapical lesions.

A case of multiple bilateral dens in dente of the maxillary anterior region with associated multiple periapical lesions of the maxilla is reported. Examination demonstrated the condition known as dens in dente to be present in all six maxillary anterior teeth. Also noted was a large palatal swelling which was confirmed to be an infected maxillary radicular cyst. The multiplicity, severity, and consequences of the dens in dente as reported in this case may indicate prophylactic restorative therapy.
