1/116. 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. ( info) |
2/116. Initiation of ectopic epithelial calcification in a calcifying odontogenic cyst. Ultrastructural observation was performed on a calcifying odontogenic cyst (COC) associated with an odontoma and arising in the right mandibular region of an 8-year-old Japanese boy. Four types of cells were identified in the epithelial layer of the COC. The basal cells were low columnar in shape and contained some intracellular organelles. They were attached to the neighboring cells with a few desmosomes and resembled inner enamel epithelium of the normal enamel organ. The stellate reticulum-like cells, polygonal in shape, possessed desmosomes and many cytoplasmic projections. Some intracellular organelles and a few bundles of tonofilaments were observed in the cytoplasm. The light oval cells that were pale staining with toluidine blue contained dilated membranous organelles and many relatively evenly distributed tonofilaments. These cells were usually scattered in the vicinity of the focal accumulations of ghost cells, and the cell membrane was discontinuous in parts. The ghost cells contained many bundles of tonofilaments that were 60-240 nm in diameter and arranged in various directions. No intact intracellular organelles were noted in the cytoplasm. They were attached to the neighboring ghost cells with some desmosomes and their cell membrane was discontinuous in parts. A variety of vesicles, 90-450 nm in diameter, were scattered among the tonofilament bundles. Some of these contained needle-like crystals that were considered to be initial calcification sites in ghost cells. These vesicles presented morphological similarities to matrix vesicles, and it is therefore suggested that matrix vesicle-like structures are deeply involved with initiation of calcification of ghost cells in COC.

3/116. Compound composite odontoma in primary dentition--a case report. Compound composite odontoma, is a tumor formed by the overgrowth of transitory or complete dental tissue, made up of one or more rudimentary teeth. Although odontomes are considered to be quite common of odontogenic tumors, these rarely occur solely in primary dentition. This paper is a report of case of a compound composite odontoma, five year old child who presented to the Department of Pedodontics and preventive dentistry, College of Dental Surgery, Manipal.

4/116. An unusual treatment with sagittal split osteotomy: report of a case involving an odontoma. Sagittal split osteotomy is one of the most commonly performed surgical techniques in the world and has been modified by many authors. The efficacy of this operation has been studied by many groups. When performing this surgery, there should be adequate contact of wide, cancellous bone surfaces, which guarantees excellent and rapid bony union in the desired position. In the present article, treatment of mandibular prognathism with open bite by sagittal split osteotomy with an odontoma in the third molar area is presented. ( info) |
5/116. Gingival peripheral odontoma in an adult: case report. BACKGROUND: odontoma arising in the extraosseous soft tissue is extremely uncommon. We describe our experience of gingival peripheral odontoma in which the initial presentation was a small asymptomatic nodule. methods: Case study. RESULTS: A 44-year-old man reported with a firm gingival mass of the anterior maxilla which had been gradually enlarging over 5 years. Radiographic examination showed a dense radiopaque mass occupying most of the tumor and no evidence of underlying intraosseous lesion. The pathology was reported as odontoma. CONCLUSIONS: This is the fourth reported case of peripheral odontoma in the gingiva. ( info) |

7/116. Restorative dentistry using a multidisciplinary approach. Multidisciplinary treatment was essential for this patient to optimally manage the occlusion and missing teeth. When the space distribution was completed, ridge management procedures for pontic site development were accomplished. The final restorative treatment required was actually minimized to a 7-unit fixed partial denture. It was apparent the multidisciplinary treatment was essential to predictably manage this patient by decreasing risk and ensuring a long-term strategy for enhanced patient satisfaction. ( info) |
8/116. 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. ( info) |
9/116. Multiple odontomas in the facial bones. A case report. A rare case of multiple compound odontoma involving the facial bones and erupting into the oral cavity of a 15-year-old Nigerian girl is presented. The unacceptable facial appearance and the surgical approach used makes this case worth reporting. ( info) |
10/116. odontoma-producing intraosseous calcifying odontogenic cyst: case report. The present report describes a case of odontoma-producing intraosseous calcifying odontogenic cyst in a 36-year-old Black male in the right mandibular bicuspid region. The lesion involved an unerupted permanent canine, which was displaced to the mandible base and a calcified mass that was later recognized as an odontoma. The lesion was surgically removed. ( info) |
