1/67. Localized deficient root development associated with taurodontism: case report.

    Dentinal dysplasia type I (DDI) is a rare disturbance in dentin formation. This case report illustrates different radiographic features from other reported DDI cases in that only one quadrant (lower right posterior teeth) has the characteristic of DDI and both right and left upper molars exhibit taurodontism. This finding might be a variation of DDI. However, it is possible that this type of developmental defect could occur because of regionalized abnormalities in cellular function and proliferation as occurs in regional odontodysplasia. ( info)

2/67. Regional odontodysplasia: an unusual case with a conservative approach.

    A case of a 14-year-old male with regional odontodysplasia is reported. In this presentation many atypical clinical and radiographical features of this condition are present. The chief complaint of the patient was the enlargement of the gingiva and, according to the literature, inflammatory processes are the main reason why patients look for care. Moreover, there was no radiographic evidence of unerupted teeth in this report. The functional and psychological benefits of the conservative approach are emphasised. ( info)

3/67. Regional odontodysplasia: report of a case involving two separate affected areas.

    The purpose of this study was to report in a 12-year old white child a rare clinical condition called regional odontodysplasia. The diagnosis was based on clinical and radiographic findings. Due to the patient's concern over appearance, the treatment involved extracting the affected teeth and subsequently placing partial removable prostheses, thus providing the patient better function and appearance. The teeth that were removed were examined histologically, both in routine preparation stained by hematoxyline and eosin, and in ground sections. ( info)

4/67. Segmental odontomaxillary dysplasia: a case report and review of the literature.

    Segmental odontomaxillary dysplasia (SOD) is a rare, unilateral developmental disorder of the maxilla involving abnormal growth and maturation of the bone, lack of one or both premolars, altered primary molar structure, delayed tooth eruption, and fibrous hyperplasia of the gingiva. In this, the twenty-third reported case of SOD, the literature is reviewed, and the clinical, radiographic, and histopathologic data are described. Computed tomographic scans of this case showed that the involved segment of the maxilla extends mesiodistally from the permanent cuspid to the mesial portion of the first permanent molar, largely limited to the area of the missing premolars. However, the affected bone extends superiorly in the lateral wall of the maxilla to the zygoma and base of the orbit. This article is intended to serve as baseline data for a future article, describing the natural history and possible treatment of SOD, which remain undocumented. ( info)

5/67. Early intervention to remove mesiodens and avoid orthodontic therapy.

    Recognition of dental anomalies is essential in determining appropriate treatment for each patient. Diagnosis and assessment of mesiodens are critical in avoiding complications such as blocking the eruption of the maxillary central incisors, cyst formation, and dilaceration of the permanent incisors. Collecting data for diagnostic criteria, utilizing diagnostic radiographs, and determining when to refer to a specialist are important steps in the treatment of mesiodens. early diagnosis and timely intervention could reduce or eliminate the need for orthodontic treatment and prevent serious complications.

6/67. Simultaneous occurrence of unusual odontodysplasia and oligodontia in the permanent dentition: report of a case.

    odontodysplasia is an uncommon clinicopathological condition with a variety of expressions. Although it is generally recognized as a localized disorder of dental tissue, its aetiology has not yet been well explained. In the present case, odontodysplasia with oligodontia in the permanent dentition is reported. The patient was in good health with normal stature and no other physical abnormalities. His parents and siblings were dentally and medically normal. The primary teeth appeared to be normal except for the primary second molars, where the enamel was malformed. However, the permanent incisors that had erupted into the oral cavity showed rough and hypoplastic enamel. An orthopantomogram showed 17 congenitally missing permanent teeth and malformation of the other 11 permanent teeth and tooth-germs. Because these findings were caused by developmental disturbances of both the mesodermal and ectodermal dental components, we diagnosed the present case as odontodysplasia accompanied by oligodontia in the permanent dentition.

7/67. Generalized odontodysplasia--a case report.

    odontodysplasia is a relatively uncommon condition that can affect both primary and permanent dentition. It is characterized by defective formation of both enamel and dentin, with enlarged pulp chambers and root canals with open apices. It is usually a localised condition where one or few teeth may be involved. Sometimes, an entire quadrant or more than one quadrant may be involved but generalized involvement is extremely rare. An interesting case of a generalized odontodysplasia affecting both primary and permanent dentition in an eight year old girl is presented here. ( info)

8/67. Regional odontodysplasia (Ghost teeth). A case report.

    Regional odontodysplasia is a rare development anomaly affecting the teeth with an unknown etiology. This dental abnormality involves the hard tissues of the teeth that are derived from both epithelial (enamel) and mesenchymal (dentine & cementum) components of the tooth forming apparatus. Teeth in a region or quadrant of maxilla or mandible are affected to the extent that they exhibit short roots, wide open apical foramen and large pulp chamber, the thinness and poor mineralisation qualities of th enamel and dentine layers have given rise to a faint radiolucent image, hence the term "Ghost teeth". Both the permanent teeth and the deciduous teeth are affected. Females are more commonly affected than males. There is a maxillary predominance (2.5:1) with a predilection for the anterior teeth. Eruption of the affected teeth is delayed or does not occur. Because of the poor quality of the affected teeth, they cannot be rehabilitated for functional use therefore the treatment of choice is extraction with prosthetic replacement. However, necrosis and facial cellulitis appear to be a complication if these teeth are retained. A unique case of regional odontodysplasia affecting the entire right quadrant of mandible is reported here. ( info)

9/67. Segmental odontomaxillary dysplasia: clinical, radiological and histological aspects of four cases.

    Segmental odontomaxillary dysplasia (SOD) is a rare developmental disorder of the maxilla, primarily involving the posterior part of the maxilla. Clinically, the disorder is often diagnosed in early childhood due to a unilateral buccolingual expansion of the posterior alveolar process, gingival enlargement, absence of one or both premolars in the affected region, delayed eruption of the adjacent teeth and malformations of the primary molars. In this report, four patients with SOD are described. The findings were similar to earlier reports, but for the first time an ipsilateral rough erythema on the skin in two of the subjects is reported. ( info)

10/67. Case report: restorative options in regional odontodysplasia.

    A case of regional odontodysplasia in a 13 year old female is reported. The restorative options in this case are considered along with the rational for providing a dentine bonded all-porcelain bridge. This approach restored both function and aesthetics with minimum destruction to the hypoplastic tooth tissue of the abutment. ( info)
