ABSTRACT: The
regional odontodysplasia, also referred as odontogenic dysplasia, is a rare
condition which has been described as an alteration of the dental development
affecting the mineralized structures of both the permanent and deciduous
teeth, and it has been associated with retardation in the eruption of the affected
teeth, gum edema, hydrocephalus and Epidermal Nevus Syndrome. The etiology is
still unknown, however, some hypotheses
have been suggested about their origin. About its incidence, this
disease is more frequent in the anterior segment of the maxilla and usually
unilateral. Epidemiologically this disease shows no predilection for any racial
group, being more frequent in the first and second decade of life and predominantly
in females. Clinically the Odontodysplasia Regional is characterized as an
hypoplasia of enamel and dentin in teeth badly formed with size alteration and
form coloration varying of the yellow to chestnut; the presence of smooth and extremely
friable dentine, tooth mobility and defective mineralization increases the
possibilities of the pulp exposure and a tendency to develop abscesses. Radio-graphically has the appearance of ghosts tooth with a bizarre morphology;
reduction of the normal radiopacity decrease of the thickness of the dentine
and enamel structures. They generally present with open apexes; shortened or
absent roots; diffuse calcification in the inside of the pulp.
Histopathologically it presents with accented reduction of the amount of
dentin, presence of great interglobular dentine areas and irregular standard of
the dentine canals. Enamel is usually thin, hypoplasic and hypocalcified. The
pulp presents atrophic areas, fibrose and hyalinization and the cement does
not have marked structural alterations.
The treatment of the Regional odontodysplasia has been the reason of many
quarrels. This present essay aims to review the literature and report a
clinical case.
