1/37. 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.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
2/37. 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.- - - - - - - - - - ranking = 0.11289808865017keywords = dental (Clic here for more details about this article) |
3/37. 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.- - - - - - - - - - ranking = 1.3386942659505keywords = tooth, dental (Clic here for more details about this article) |
4/37. 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 = 1.1128980886502keywords = tooth, dental (Clic here for more details about this article) |
5/37. 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.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
6/37. Segmental odontomaxillary dysplasia: an unusual orthodontic challenge.Segmental odontomaxillary dysplasia has only recently been delineated from other osseo-odontogenic dysplasias. Yet, this seldom-reported developmental abnormality might be diagnosed by a unique combination of clinical, radiographic, and histologic findings. Unilateral maxillary hyperplasia combined with displaced molars and unusual bone trabeculation is quite obvious at an early age. Recognition and subsequent reporting by dental specialists is encouraged to more clearly define the natural progression and the appropriate treatment of this abnormality.- - - - - - - - - - ranking = 0.11289808865017keywords = dental (Clic here for more details about this article) |
7/37. Regional odontodysplasia: expression of matrix metalloproteinases and their natural inhibitors.Regional odontodysplasia is a localized disorder of tissues of dental origin that results in a ghost-like appearance of the affected teeth. We present a case with a study of gingival tissue around the follicle. The results show evidence of the role of the matrix metalloproteinases and their natural inhibitors by resident cells in this pathosis. An imbalance in the amounts of matrix metalloproteinases and their natural inhibitors is associated with the pathologic breakdown of the collagen.- - - - - - - - - - ranking = 0.11289808865017keywords = dental (Clic here for more details about this article) |
8/37. An unusual case of regional odontodysplasia.A case is presented of a 3-year-old child with regional odontodysplasia affecting all erupted and developing mandibular teeth. Maxillary teeth were unaffected. This pattern of distribution does not appear to have been reported previously and the extent of involvement poses problems for the long-term dental management of the patient.- - - - - - - - - - ranking = 0.11289808865017keywords = dental (Clic here for more details about this article) |
9/37. Regional odontodysplasia. A case report.Regional odontodysplasia (RO) is an unusual, non-hereditary anomaly of the dental hard tissues with characteristic clinical, radiographic and histological findings. Etiology is unknown, and treatment, while varied, should be appropriate for each individual's clinical findings. In the case reported here, a 2-year-old female was diagnosed with RO. Extractions were performed under general anesthesia. Clinical, radiographic, and histological findings are described.- - - - - - - - - - ranking = 0.11289808865017keywords = dental (Clic here for more details about this article) |
10/37. Regional odontodysplasia: a review of the literature and report of four cases.Regional odontodysplasia (RO) is a rare dental anomaly involving both dentitions, mostly teeth of one quadrant. The characteristic findings are discolored soft teeth accompanied by gingivitis, swelling or abscess. Enamel and dentin are hypomineralised and hypoplastic, so that the 'ghost teeth' appear shadowy in radiographs with wide pulp chambers. The etiology is unknown. Epidemiological data is rare; 138 cases of RO have been published to date and reports on ultrastructure are few. An analysis of published cases of RO in the international literature is presented. The sex ratio of females to males was 1.7:1. The age at the time of diagnosis ranged between 4 and 23 years. The maxilla was more often affected (maxilla to mandible ratio 1.6:1). In 67 patients the deciduous and permanent dentitions were affected (47.1%). In 129 cases, affected teeth lay side by side. Missing tooth development was observed in 10.7%. Failure of tooth eruption of RO teeth occurred in 39.7%. In addition, four cases with RO which were collected over a period of more than 25 years are presented. Ultrastructural findings of one specimen are demonstrated.- - - - - - - - - - ranking = 2.1128980886502keywords = tooth, dental (Clic here for more details about this article) |
