Clinical Management of Regional Odontodysplasia.

Odontodysplasia is a rare developmental anomaly in tooth formation generally
observed in young patients.

This disease is characterized by the malformation and
hypocalcification of both the enamel and dentin, asymmetrically and locally.

Since the initial description by McCall and Wald, approximately 125 cases
have been reported in the dental literature worldwide.

The disease is variously described as odontodysplasia, localized arrested tooth
development,3,4 odontogenesis imperfecta, and unilateral dental malformation.

Rushton termed the disease “ghost teeth” due to the ghost-like appearance of the teeth radiographically.

Here we report a case of regional odontodysplasia in a 7-year-old Japanese girl. The patient was
followed up for 6 years and had normal occlusion.

According to the patient’s mother, tooth numbers 64 and 65 erupted at 6 months after
birth and were very different from those on the other side of the maxilla, with altered morphology and a yellowish color.

The external appearance of 26 was similar to that of 64 and 65, and associated with
some swelling and redness. No undisputed cases of regional odontodysplasia were observed
in other family members.

Tooth numbers 24, 25, and 27 were still inside the bone.
The number and morphology of the remaining dentition were normal.

According to the literature, regional odontogenesis is slightly more prevalent in females8
and slightly more often involves the maxillary arch.

In this case, the patient was female and the maxillary arch was affected.
Both the dentition  were affected, and the age of
diagnosis was during primary tooth eruption as well as during mixed dentition.
