Regional odontodysplasia: report of four cases

Abstract

Four cases of regional odontodysplasia are described. Clinically erupted teeth appear hypoplastic and are often mobile. The radiographic appearance has given rise to the term 'ghost teeth' and the cases presented demonstrate this with short roots which are less well calcified than normal teeth. Clinical and radiographic findings showed that this condition affects only one side of the jaw, but can be seen in any part of the upper or lower jaws. This article represents cases in different parts of the mouth with varying degrees of involvement.

Regional odontodysplasia: Account of clinical case in permanent teeth

“…Authors agree that the deciduous dentition and the permanent one can be affected, in the presented case both dentitions are involved. When the teeth affected exceeds the median line, the condition passes to be called as generalized odontodysplasia [13].…”

“…Some authors say that the extraction of the involved elements and posterior confection of prosthesis would be the best option [27]. Another group of authors indicate dentistic procedures, if possible, for the aesthetic and functional reestablishment of the patient [13,36,44].…”

“…In relation to the epidemiology of this pathology, Crawford & Alfred [12] state that the age group of bigger prevalence is between the first and the second decade of life; without predilection for any racial group. In relation to the sex, the feminine one is more frequently attacked [3,6,[13][14][15][16].…”

“…The treatment can be to extract the dysplasic teeth and to the confection of prosthesis [4,19,27], or when the teeth erupt, can use prosthetic resource of dentistic (metallic restorations and/or crowns) to try to reestablish the patient aesthetically and functionally [13,36,44]. It should also be taken into account that the choice of treatment depends on the grade of dental development, aesthetic and functional needs, the patient's age, the number of teeth affected and the attitudes and desires of the child and parents [2][3][4]19].…”

Simultaneous occurrence of unusual odontodysplasia and oligodontia in the permanent dentition: report of a case

“…Congenital absence of teeth may arise from (1) physical obstruction or disruption of the dental lamina, (2) space limitation, (3) functional abnormalities of the dental epithelium, (4) failure of induction of the underlying mesenchyme, and genetic factors have also been suggested [7]. There have been few reports concerning odontodysplasia with units in the same dentition being congenitally missing [8,9]. This report presents a rare case of odontodysplasia accompanied by oligodontia in the permanent dentition.…”
