Bilateral dens invaginatus in the mandibular incisor region.

A case of bilateral dens invaginatus in the mandibular incisor regions has been reported. Radiographs demonstrated invaginations in both of the incisors in the mandibular incisor region and also demonstrated a periapical radiolucency. Clinical examination revealed two anomalous incisors and apparently there was congenital absence of two mandibular incisors. Dens invaginatus in the mandibular incisors would appear to be a most unusual occurrence.
