Clinical Management of Regional Odontodysplasia

Abstract

Here we present a case of a 7-year-old Japanese girl with regional odontodysplasia affecting
tooth numbers 24, 25, 26, and 27. No other teeth were affected. Partially erupted tooth
number 26 had a rough enamel surface and was yellow-brown in color. Tooth numbers 24, 25,
and 27 had not erupted. Radiographically, numbers 24, 25, 26, and 27 seemed to be undeveloped
with large pulp chambers, short roots, and open apices, and exhibited the so-called ghostlike
appearance. Histopathologically, number 26 had uneven thin enamel and dentin, revealing
hypoplasia and hypocalcification, and irregular dentinal tubes. The patient was followed up for
6 years and had similarity normal occlusion.
