1/30. Compound odontoma--diagnosis and treatment: three case reports.Odontomas are the most common type of odontogenic tumors and generally they are asymptomatic. This paper describes three cases of compound odontomas diagnosed in children due to dislodgement or over-retention of primary anterior teeth and/or swelling of the cortical bone. In all cases, the surgical excision of the lesions was performed and, in one case, orthodontic treatment was adopted in order to move an impacted permanent tooth to its normal position. The results achieved indicate that the early diagnosis of odontomas allows the adoption of a less complex and expensive treatment and ensures better prognosis.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
2/30. Delayed tooth eruption associated with an ameloblastic fibro-odontoma.Delayed eruption of a single primary tooth is an uncommon event. Excluding a previous traumatic insult, the presence of a pericoronal odontogenic cyst or neoplasm is the primary cause for this abnormality. This case report describes the clinical and radiographic features of an ameloblastic fibro-odontoma in a young child, who presented with delayed eruption of the primary mandibular canine and prominent buccal expansion. A differential diagnosis for mixed, radiolucent and radiopaque lesions of the jaws will be discussed.- - - - - - - - - - ranking = 5keywords = tooth (Clic here for more details about this article) |
3/30. Recurrent infection of a complex odontoma following eruption in the mouth.Odontomas are the most common odontogenic tumors, and are classified as either compound or complex lesions. Although its underlying etiology remains unclear, a number of factors appear to be involved (e.g., prior trauma). The lesions are generally diagnosed in the second decade of life, often in the context of routine dental X-ray examinations. A complex odontoma is described in a 22-year-old woman referring discomfort due to overinfection following its aperture into the oral cavity in the distal alveolar region of 2.6. Initial treatment consisted of antibiotics and antiinflammatory drugs. Computed axial tomography revealed a solid, irregular mass in the distal zone of the left maxilla, imprinting upon the region of the maxillary sinus on the same side. Surgical resection was performed, raising the alveolar mucosa and upper left vestibular fundus. The surgical piece contained the amorphous adenoma mass and the tooth 2.7.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
4/30. The secretion of amelogenins is associated with the induction of enamel and dentinoid in an ameloblastic fibro-odontoma.Ameloblastic fibro-odontoma is the unique entity of epithelial-ectomesenchymal odontogenic tumors, which is characterized by enamel formation in addition to dentine. We examined immunohistochemically a case of this tumor in which enamel having prism structures was developed in the absence of odontoblast differentiation but was in contact with mesenchymal matrices. Histological examination showed diverse morphological features of epithelial tumor cells, e.g., cuboidal cells comprising tooth bud-like projections, ameloblast- and stellate reticulum-like cells, and residual cells in forms of extended cords or islands of odontogenic epithelium. Immunostaining with anti-amelogenin sera proved that the intracellular production of amelogenins was initiated at the tooth bud-like stage. The secreted amelogenins were detected almost exclusively in the induced enamel and dentinoid areas, as well as in the core region of cementicle-like spheres deposited in the encapsulating stroma. The results obtained indicate that the odontogenic tumor epithelia and its products, i.e., amelogenins, participate in multifaceted aspects of dental hard tissue formation that takes place during oncogenesis.- - - - - - - - - - ranking = 2keywords = tooth (Clic here for more details about this article) |
5/30. Compound odontoma: a case study.Odontomas are the most common odontogenic tumors and are usually incidental findings in radiographic examination. They are classified as either compound or complex. Both types are composed of enamel, dentin, cementum, and pulp tissues. Compound odontomas appear radiographically as rudimentary toothlets and can be diagnosed from radiographs alone, while complex odontomas appear as indistinguishable radiopaque masses and require resection for definitive diagnosis. They are frequently found in association with other abnormalities, and surgical excision is recommended for both types by most practitioners. The possibility of discovering lesions such as the odontoma supports the practice of recommending baseline radiographic surveys for all dental patients.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
6/30. Compound odontoma associated with an unerupted and dilacerated maxillary primary central incisor in a young patient.The occurrence of odontoma in the primary dentition is uncommon. There are very few reports of non-eruption of a dilacerated primary tooth in the literature. A rare case of compound odontoma in association with an unerupted dilacerated maxillary primary incisor in a young patient is reported. There was also a developing supernumerary tooth in the vicinity of the odontoma. The clinical features and management of these conditions are discussed. The relevant literature is reviewed. A possible causal relationship between odontoma and dilaceration is highlighted.- - - - - - - - - - ranking = 2keywords = tooth (Clic here for more details about this article) |
7/30. Case report: two nasal floor compound odontomas associated with impacted maxillary incisor.AIM: The purpose of this report is to describe the logical sequence of treatment in a case of a six year old caucasian female patient with two nasal floor compound odontomas, that delayed eruption of a maxillary permanent incisor. TREATMENT: The odontomas were surgically removed. However, as the maxillary incisor did not erupt spontaneously, after a suitable period of observation, an orthodontic treatment approach was adopted. This was to obtain an adequate space for the unerupted tooth and to move it to its normal position. CONCLUSION: Early diagnosis and surgical intervention of supernumeraries is therefore necessary and treatment of an impacted tooth may require an orthodontic appliance.- - - - - - - - - - ranking = 2keywords = tooth (Clic here for more details about this article) |
8/30. Odontomas--report of 3 cases.Three clinical cases of odontoma were detected in 2 children and 1 adolescent. The tumors were surgically removed. Clinical suspicion was based on facial deformity in one of the cases and on the absence of permanent tooth eruption in the other two. Radiographic evidence of odontoma was confirmed through histological study.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
9/30. Eruption of a severely displaced second permanent molar following surgical removal of an odontoma.The process of tooth eruption is very complex, and many of its factors remain unknown. Although radiographic features can provide clues into the eruptive potential of a tooth, underlying factors that affect tooth development and eruption are not as well defined, ranging from local disturbances to systemic disease. In addition, it is difficult to predict which teeth will require treatment and when the optimal time is to intervene. The purpose of this report is to illustrate the eruption potential of an impacted molar following the removal of a developing odontoma, despite its unfavorable position in the bone, complete root development, and orthodontic attachment loss.- - - - - - - - - - ranking = 3keywords = tooth (Clic here for more details about this article) |
10/30. Rare compound odontoma of the mandible in a 7-year-old child: case report.BACKGROUND: A compound odontoma is a mixed tumor of odontogenic origin, in which both ectodermal and mesenchymal cells exhibit complete differentiation, resulting in the formation of tooth structures. It occurs with equal frequency in both sexes, and is often initially asymptomatic. CASE REPORT: A 7-year-old boy was recently examined in our Department for management of a compound odontoma. Surgical treatment was invasive because of the size of the lesion, but it was possible to use interceptive orthodontic treatment to restore the dental arch.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
