1/39. Delayed eruption of maxillary primary cuspid associated with compound odontoma.

    Impaction of primary teeth is very rare especially in the maxillary anterior teeth. A four-year-old male child with the complaint of delayed eruption of right maxillary primary cuspid due to the presence of odontoma is presented.

2/39. A case report of a compound odontoma causing delayed eruption of a central maxillary incisor: clinical and microscopic evaluation.

    A case of a compound odontoma caused delayed eruption of a central incisor in the maxilla is presented with clinical, radiographic, and microscopic findings. The odontoma was surgically removed and microscopic examination showed a lot of crown-like structures in a very irregular form, some of which were fused to each other at their apical parts. Enamel and pre-enamel were totally abnormal, whereas the inside of the pulp chamber tissue did not present any histological sign of functional tissue. The most homogeneous tissue was dentin. The removal of the odontoma was followed by a rapid eruption of the impacted central incisor.

3/39. 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.

4/39. 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.

5/39. 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.

6/39. 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.

7/39. Ameloblastic fibro-odontoma: a case report.

    Ameloblastic fibro-odontoma is a benign epithelial odontogenic tumour with odontogenic mesenchyme exhibiting the histologic characteristics of ameloblastic fibroma and complex odontoma. It is usually associated with developing teeth and occurs predominantly in children and adolescents. In many cases, such lesions are found on radiographic evaluation of patients in whom eruption of teeth is delayed. Ameloblastic fibro-odontoma is generally asymptomatic but may cause swelling and discomfort. This report describes an ameloblastic fibro-odontoma in the posterior mandible of a 26-year-old woman and discusses the histogenesis and clinical features of the lesion.

8/39. 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.

9/39. 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.

10/39. 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.
