1/7. 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.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/7. Regional odontodysplasia. Case report with etiologic and treatment considerations.Regional odontodysplasia, a relatively rare developmental abnormality of the dental hard tissues, most often unilaterally and segmentally involves the anterior maxillary teeth of young females. patients often have pulpal pathosis, periodontal manifestations, and irregularities of the eruption sequence of the affected teeth. The resultant reduced density of the enamel and dentin imparts a radiographic appearance of "ghosting" with correspondingly enlarged pulp chambers and canals. Etiology is uncertain; numerous local and systemic factors have been proposed. Treatment may sometimes be controversial, and timing of extractions and restorative procedures is critical. This case report illustrates the signs and symptoms of regional odontodysplasia, to aid clinicians in early recognition of the condition, to provide further evidence that a local circulatory disorder might be involved in its pathogenesis, and to illustrate treatment options that consider the patient's development and welfare.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/7. Conservative management of regional odontodysplasia: case report.Regional odontodysplasia is an uncommon developmental anomaly affecting a localized area of the dentition. The affected teeth are often grossly malformed and develop abscess soon after eruption. Although extractions are often required, in some milder cases the teeth may be retained for a long period. The treatment plan should be based on the degree of involvement as well as functional and esthetic needs in each case. This article describes a conservative treatment approach in a 10-year-old boy with regional odontodysplasia.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/7. Regional odontodysplasia presenting as a soft tissue swelling.An unusual case of regional odontodysplasia in a 13-year-old black girl is presented. Although the affected teeth displayed features characteristic of odontodysplasia, the patient appeared with significant soft tissue swelling of the buccal and palatal maxilla. Treatment consisted of extraction of affected teeth, removal of involved tissue, and histologic examination.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/7. Unilateral odontodysplasia.A case of malformation of five permanent teeth in the right maxilla is described. The asymmetrical malformations were probably caused by an early local trauma of the right maxilla. This trauma led to defective mineralization of the deciduous tooth germs, which was verified roentgenologically. The resulting early osteitic process caused injury to the permanent germs at a sensitive mineralization period. Mineralization disturbances of 13, 14, 15, 16 and 17 were established roentgenologically. In the other halves of the jaws the development was entirely normal. Endocrinological examination showed normal values and there were no signs of hypothyreosis or Turner's syndrome. Acute symptoms in the right maxilla at the age of 9 necessitated extraction of germs 14 and 16. As subsequent roentgenograms showed that 13 and 15 were not developing normally in respect of mineralization, these were extracted at, respectively, 12 and 13 years of age. For the same reason 17 was extracted two years later. The histopathological examination showed in all involved teeth a pronounced malformation with disturbances both of the morpho- and histodifferentiation of the various dental tissues.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/7. Regional odontodysplasia.An unusual case of regional odontodysplasia in an 8-year-old boy is presented. He was referred to our clinic because of failure of tooth eruption on the left side of the maxilla and frequent fever attacks. Treatment consisted of extraction of the affected teeth, and removal of inflamed tissue.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/7. Regional odontodysplasia: review of the literature and report of a case.Regional odontodysplasia is a rare and unique dental developmental anomaly that affects tooth morphogenesis. This case is unusual in that it involved the mandibular dentition. However, in this case the mandible was unilaterally involved. The presence of an abscess in relation to the lower right first permanent molar, in the absence of deep caries or periodontal pathology was an interesting finding. The radiographic appearance of bizarre pulpal morphology with high pulp horns extending to the occlusal surface would provide an open communication between the pulpal tissue and oral cavity. The importance of the first permanent molar as a strategic tooth was recognized and an apexification procedure was performed. The care and treatment of a child with odontodysplasia requires a multidisciplinary approach. In this case the right lower primary cuspid and first primary molar had been extracted previously. The early extraction of these teeth and the subsequent delay in hard tissue formation and eruption of the permanent successors could have resulted in altered growth of the alveolus in this region.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
