Regional odontodysplasia is a rare developmental disorder of enamel and dentin. The result is localized arrested in tooth development. Odontodysplasia affects the primary and permanent dentitions in the maxilla mandible or both jaws. Odontodysplasia tend to unilateral development, but, has been reported to involve both side of the midline. Clinically affected teeth appear discolored, hypoplastic, and hypocalcified - an appearance that can resemble dental caries. The teeth tend to be shorter, have short roots with open apices, and abnormally wide open apices. Radiographically affected teeth are poorly discernible, having a reduced radiodensity. The enamel and dentin layers are thi and defective, producing a faint, fuzzy outline. This appearance used term of 'ghost teeth'. Teeth in regional odontodyplasia have the wide pulp chambers and canals. The roots apear short and stubby with open apices.
In this case, a 5 years 9 months old female visited fot a treatment of missing of #81,82,83. During radiographic examination, permanent successful tooth are found regional odontodysplasia.
