1/42. 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) |
2/42. A suspected periradicular scar: treat or not?This paper presents an unusual case of a tooth with multiple adjacent endodontic problems. The diagnosis was complicated by a bony scar that untypically was located around the apex of one of the teeth.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
3/42. Follicular or dentigerous (tooth-containing) cyst in the premaxilla of an otherwise edentulous 65-year-old man.A unilocular follicular or dentigerous cyst (FDC) with a diameter of 12 mm was observed incidentally in the premaxilla of a midsagittal section of the head of a 65-year-old cadaver. The mucosal lining of the cyst was grey in color and granular in texture: the osseous walls had a thickness of less than 1 mm. In the floor of the cyst, a slender, fully developed incisor tooth was fixed in a horizontal position. The alveolar processes of the maxilla and mandible were completely edentulous. Postmortem computer tomography showed the cyst in an osteolytic lesion of the premaxilla, and histology revealed a lining of non-keratinized stratified squamous epithelium supported by a lamina propria of dense connective tissue. copyright Wiley-Liss, Inc.- - - - - - - - - - ranking = 5keywords = tooth (Clic here for more details about this article) |
4/42. Two cases of totally submerging buried primary molars: characterization of clinical behavior and discussion of cause.Submerging buried tooth is a rare condition whose clinical characteristics are unclear. Two cases are reported of submerging buried maxillary second deciduous molar. A review of the literature in Japanese and English provides the clinical condition of the lesion and allows for discussion of its causes.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
5/42. Ameloblastic fibroma of the anterior maxilla presenting as a complication of tooth eruption: a case report.Ameloblastic fibroma is a rare mixed odontogenic tumour, which is extremely uncommon in the anterior maxillary region. A case report is presented where failure of eruption of an upper central incisor was the presenting feature.- - - - - - - - - - ranking = 4keywords = tooth (Clic here for more details about this article) |
6/42. Maintaining and attenuating periodontal tissues for aesthetic implant placement.Alveolar ridge resorption and soft tissue recession after tooth extraction inevitably disrupted the harmonious pre-existing periodontal complex, compromising clinicians' ability to recreate successful aesthetic restorations. Although numerous surgical procedures had been advocated for the augmentation of both the alveolar ridge and its soft tissue to ideal contours, questions remain regarding viability and predictability of these procedures. This is especially critical in the maxillary anterior region, where a the condition of the soft tissue complex and its relationship to the implant restoration and its adjacent dentition often determines the implant's success. The described technique of retaining the root remnant and inducing the proliferation of the surrounding tissue in conjunction with immediate implant placement results in the preservation of existing soft and hard tissue, thus minimizing the necessity of grafting procedures and facilitating primary flap closure during implant placement.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
7/42. Case report: a large radicular cyst involving the entire maxillary sinus.cysts of the maxillary sinus of odontogenic origin have been well-documented in the literature. Most of these lesions involve the apex of the offending tooth and appear as a well-defined periapical radiolucency. Presented here is a case of an unusually large lesion, which involved the entire maxillary sinus and extended into the floor of the nose. The lesion also caused paresthesia on the affected side. The lesion was removed with conservative treatment without any postoperative complications.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
8/42. Combined therapy of mineral trioxide aggregate and guided tissue regeneration in the treatment of external root resorption and an associated osseous defect.BACKGROUND: The treatment of external root resorption and associated periodontal defects can be challenging to the most astute clinician. In this case report, a multidisciplinary approach was performed to treat a maxillary central incisor that presented with a sinus tract. An amalgam restoration had been placed approximately 10 years earlier to repair an area of external root resorption. methods: A full-thickness mucoperiosteal flap was reflected from teeth #8 to #9. Following degranulation of the area, an amalgam restoration was found on the distal root surface of tooth #8. A 2-wall osseous lesion was also associated with the distal surface of #8. The amalgam was removed and the defect was restored with mineral trioxide aggregate (MTA). The root surface was chemically conditioned with tetracycline, and the osseous defect was grafted with decalcified freeze-dried bone allograft (DFDBA) and a calcium sulfate barrier. RESULTS: An 8 mm gain in clinical attachment, as well as an increase in radiodensity, was noted on the distal surface of tooth #8 at 15 months postsurgery. The patient was also asymptomatic, with no clinical signs of inflammation present. CONCLUSIONS: A combined approach utilizing MTA for root surface repair, and DFDBA and calcium sulfate to address an associated osseous lesion, appears to be a viable modality in the treatment of chronic endodontic/periodontal lesions.- - - - - - - - - - ranking = 2keywords = tooth (Clic here for more details about this article) |
9/42. Eruption cyst formation associated with cyclosporin A.BACKGROUND: Cyclosporin A (CyA) is a potent immunomodulatory agent with a wide range of applications. Despite its therapeutic value, multiple adverse effects of CyA have been identified. This case report describes eruption cyst formation as a possible adverse effect of CyA administration during tooth eruption in a boy treated with CyA as a consequence of a cardiac transplantation. The clinical diagnosis of eruption cyst was confirmed by histopathological examination. TREATMENT: The periodontal treatment consisted of supragingival and subgingival scaling, followed by surgical removal of the tissues overlying the crowns of the teeth associated with eruption cysts, and flap surgery in the region of gingival overgrowth. The patient was then placed on quarterly periodontal supportive therapy and his immunosuppressive medication was switched from CyA to tacrolimus. RESULTS: Twenty months after therapy, neither new cyst formation nor recurrence of gingival overgrowth was registered. CONCLUSION: Formation of an eruption cyst may be an adverse effect of CyA in children with erupting teeth.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
10/42. Radiological features of glandular odontogenic cyst.OBJECTIVES: To present five new cases of glandular odontogenic cyst (GOC) and to review the radiological features at presentation as reported in the English literature. methods: From 1993 to 2002, five patients in our department were diagnosed with GOC based on histopathological findings and supported by radiography and CT. The radiographic features of the new GOC cases were analysed in addition to 51 literature cases. RESULTS: There were 31 male and 25 female patients, aged 14-90 years (mean 50 years). The mandible was involved in 80% and the maxilla in 20%; most of the lesions were located in the anterior jaw. Radiographically, 52% of the lesions were unilocular and 48% were multilocular; 94.5% showed well defined borders, which were sclerotic in 7.7% and scalloped in 13%. Information on cortical plate integrity was available in only 24 cases: 50% showed perforation, 8.3% erosion of the cortical plates and 8.3% thinning of the cortical plates. root resorption was reported in 22% of patients and tooth displacement in 24.4%. CONCLUSIONS: Data collected indicate that GOC has potentially aggressive behaviour, with expansion and perforation in a significant number of cases. We recommend the use of multiple plane radiographs, with CT reserved for large lesions, especially those that are multilocular or involve extragnathic structures.- - - - - - - - - - ranking = 1keywords = tooth (Clic here for more details about this article) |
