1/40. 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.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/40. Histological and analytical studies of a tooth in a patient with cleidocranial dysostosis.A histopathological and analytical study of a permanent tooth from a patient with cleidocranial dysostosis (CCD) was performed. The patient was a 47-year-old woman, who had 10 erupted permanent teeth and 2 partially erupted and 19 completely impacted teeth, including supernumerary teeth. The erupted right upper premolar was extracted and observed using a light microscope and an electron probe X-ray microanalyzer (EPMA). Findings showed enamel hypoplasia, predominantly irregular globular dentin and Tomes' granular layer, and a complete lack of cellular cementum in the ground section. The incremental von Ebner and counter Owen lines were obscure. Comparative quantitative analysis using the EPMA showed that the quantities of calcium and phosphate were lower in the enamel and dentin than those of the control sample.- - - - - - - - - - ranking = 0.022350060738115keywords = lower (Clic here for more details about this article) |
3/40. Submerging deciduous molars--an extraction in time!A case is presented of a 25-year-old man with a submerged lower second deciduous molar and an impacted lower second premolar. Treatment was complicated by the relationship of the teeth to the inferior dental nerve, which necessitated extensive bone removal and mental nerve transposition to remove the submerged and impacted teeth. Early recognition and treatment of the submerging tooth might have prevented the need for such extensive surgery and morbidity at a later date.- - - - - - - - - - ranking = 0.04470012147623keywords = lower (Clic here for more details about this article) |
4/40. Clinico-pathological aspects of a residual natal tooth: a case report.A Japanese girl was referred to Osaka University Dental Hospital for examination of a tooth-like structure that had erupted following spontaneous exfoliation of a natal tooth in the lower left primary central incisor region. The structure had erupted at 6 months of age, and radiographic and clinical examination showed composition of pulp and dentin, but no enamel. On histological examination, the majority of the dentin area had a tubular dentin-like appearance, while the outer area of the root appeared to be composed of an osteodentin-like substance. Most of the dentin was covered by cementum. These findings suggest that the structure had originated from a developing remnant of the extracted natal tooth, which must have remained in the gingival tissues. We termed this calcified structure a residual natal tooth.- - - - - - - - - - ranking = 0.022350060738115keywords = lower (Clic here for more details about this article) |
5/40. Supplemental premolars in a 13 year old child--a case report.A case of 13 old year is presented with supernumerary maxillary premolars one on either side. Radiograph revealed presence of five more supernumerary teeth unerupted in both maxilla and mandible. The implications of early diagnosis and management to prevent further complications are discussed.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
6/40. The conservative approach to managing unerupted lower premolars -- two case reports.General dental practitioners frequently refer patients with unerupted premolars for specialist management. The frequency of unerupted lower second premolars in 15-year-old children has been cited as high as 9.7%. Two cases are discussed involving unilateral unerupted premolars, which initially appear to be in unfavourable positions. The first patient was referred at 16 years of age and presented with an unerupted lower left first premolar positioned along the lower border of the mandible. The second patient presented with an unerupted distally inclined, horizontally positioned second premolar impacting on the roots of the first permanent molar. Both cases were reviewed without any treatment, and both premolars erupted into excellent positions. This raises important questions concerning the possible treatment options for such teeth as well as the timing of any interceptive treatment. In cases where premolars are unerupted or impacted, a multidisciplinary approach is indicated involving orthodontics, paedodontics and oral surgery to establish the optimal treatment plan.- - - - - - - - - - ranking = 1.1564504251668keywords = mandible, lower (Clic here for more details about this article) |
7/40. Case report--Scanora imaging of an unusual unerupted tooth located entirely below the inferior dental canal.We present an unusual case of an unerupted tooth located beneath the inferior dental canal (IDC) seen as an incidental finding on a dental panoramic radiograph (DPR). An unerupted premolar was identified on the DPR lying horizontally and located entirely below the inferior dental canal in the first and second molar region. The crown was distally orientated and was somewhat demineralised. As this unerupted tooth appeared to have an intimate relationship with the inferior dental canal, which in turn had a close relationship with the distal roots of the lower left first molar, this relationship was investigated further. Spiral tomography using Soredex's Scanora unit was used to obtain three contiguous 2 mm thick cross-sectional images of the area, which showed the separation of the inferior dental canal from both the first molar tooth above and the unerupted premolar. This case highlights the role of Scanora cross-sectional imaging in establishing accurately the relationship between teeth and the inferior dental canal and to document the unusual position of this unerupted tooth.- - - - - - - - - - ranking = 0.022350060738115keywords = lower (Clic here for more details about this article) |
8/40. Canine ectopia: report of two cases.Transmigration of mandibular canine is a rare elusive phenomenon described in dental literature. The eruption of such transmigrated canines is even rarer. Two rare cases one of midline mandibular canine and the other of transmigrated mandibular canine across the midline and erupted distal to the opposite lateral incisor are presented. The transmigrated canine maintained its nerve supply from the original site. It is suggested that on routine evaluation of orthopantomograms when the dentist finds an excessive mesial inclination of the unerupted mandibular canine at 8-9 years associated with proclination of lower anteriors. increased axial inclination of the unerupted canine and an enlarged symphyseal cross section area of the chin, it is best to keep such a patient under routine evaluation.- - - - - - - - - - ranking = 0.022350060738115keywords = lower (Clic here for more details about this article) |
9/40. Transmigration of mandibular permanent canine in a Nigerian patient: presentation and management.A rare dental anomaly--transmigration is presented in a 12-year-old female Nigerian who was referred for orthodontic assessment. A right mandibular canine was found completely located in the left side of the body of the mandible having moved ectopically and progressively from its normal developmental site through the symphysis of the mandible. The importance of the radiological diagnosis with the use of panoramic radiograph is highlighted and the management briefly discussed.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
10/40. osteopetrosis--a review and report of two cases.We present a brief review of the rare condition of osteopetrosis together with two case reports of this disease in the same family affecting the jaws. The first in a 41-year-old woman, and the second in her 39-year-old brother. Plain films and computed tomography showed marked sclerosis of the affected bones with obliteration of the medullary cavities and thickening of the cortices as well as multiple absent and unerupted teeth. In addition radiographs showed discrete mixed radiopaque/radiolucent areas consistent with the appearance of fibro-cemento-osseous dysplasia, but which may also represent part of the overall spectrum of bone changes in osteopetrosis.- - - - - - - - - - ranking = 0.20749707799686keywords = jaw (Clic here for more details about this article) |
