1/59. Central neurilemmoma of the jaws. review of literature and case report.Neurilemmomas presenting as primary central bone tumors are extremely rare. Only 21 cases have been reported to have arisen in the jaws; all except for one have occurred in the mandible. The majority of these have been associated with the inferior dental nerve. A case of a central neurilemmoma arising in the anterior mandible is reported. Its probable origin is from one of the alveolar branches of the incisive nerve--an unusual site in the mandible. The radiographic features include expansion of cortical bone, resorption of roots of teeth, the presence of lace-like bony septa and a spotty calcification within the tumor. The treatment and the prognosis are briefly discussed.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/59. Resin-ionomer and hybrid-ionomer cements: part II, human clinical and histologic wound healing responses in specific periodontal lesions.Twenty-five subjects with a total of 50 subgingival restorations participated in this study. At the beginning of the investigation, nine teeth that were considered hopeless because of the extent of their pathology were selected for extraction to evaluate histologically the restorations and their effect on the adjacent tissues. The purpose of this article is to demonstrate the responses to the clinical applications as well as to the placement of resin-ionomers in subgingival lesions. Clinical and histologic evidence of epithelial and connective tissue adherence to resin-ionomer restorative materials was observed during the healing process.- - - - - - - - - - ranking = 0.014833773532833keywords = process (Clic here for more details about this article) |
3/59. Treatment of invasive cervical resorption: an analysis of results using topical application of trichloracetic acid, curettage, and restoration.OBJECTIVE: The purpose of this study was to carry out a clinical evaluation of the treatment of invasive cervical resorption. METHOD AND MATERIALS: Topical application of a 90% aqueous solution of trichloracetic acid, curettage, nonsurgical root canal treatment where necessary, and restoration with glass-ionomer cement were performed on 94 patients with a total of 101 affected teeth. A minimum of 3 years' follow-up was required, unless failure occurred before that time, in which case that treatment was included. Teeth were divided into four classes, depending on the extent of the resorptive process. Class 1 represented the least invasive resorptive lesion, near the cervical area with shallow penetration into dentin, while class 4 represented the most invasive resorptive process, which had extended beyond the coronal third of the root. RESULTS: In all class 1 and class 2 cases, the results showed complete success, judged by an absence of resorption or signs of periapical or periodontal pathosis. When overall success was judged by absence of resorption and periapical or periradicular pathosis, the success rate in class 3 lesions was 77.8%. Only 12.5% of teeth in class 4 were free of resorption and deemed to be clinically sound. CONCLUSION: The treatment regimen was successful in class 1 and class 2 cases, reasonably successful in class 3 cases, and generally unsuccessful in class 4 resorptions, where alternative treatment is recommended. diagnosis of lesions at an early stage is, therefore, highly desirable.- - - - - - - - - - ranking = 0.029667547065666keywords = process (Clic here for more details about this article) |
4/59. root resorption and signs of repair in Papillon-Lefevre syndrome. A case study.The aim of this investigation was to describe some tooth-related histological features of prepubertal periodontitis. Teeth extracted during treatment of two Papillon-Lefevre syndrome patients were processed by means of the sawing and grinding technique. light microscopy examination revealed little or no cementum in the coronal parts of the roots. Resorptions of various depths (0.02 to 1.5 mm) and to various extents (affecting up to 1/3 of the root surface) were observed in the 5 investigated teeth. Some resorptive defects on 1 of the examined incisors showed signs of spontaneous repair. Extrinsic fibers were inserted into the new cellular intrinsic fiber cementum which had formed directly on the bottom of the defect. Intact acellular extrinsic fiber cementum was found where fibers were still attached. Here, the characteristic of pristine cementum, a hyaline layer of peripheral dentin, could be identified. If resorption was not present, the cementum did not show any signs of hypoplasia. Thus, histological features of prepubertal periodontitis in the current material were (i) areas of extensive resorption, (ii) signs of spontaneous repair, and (iii) healthy cementum.- - - - - - - - - - ranking = 0.014833773532833keywords = process (Clic here for more details about this article) |
5/59. Successful root coverage: a human histologic evaluation of a case.connective tissue grafts combined with pedicle grafts (subepithelial grafts) have been shown to be effective in obtaining root coverage. Unfortunately, little is known about the histology of the results in humans. This is a case report of a tooth with a recession defect that was treated with a subepithelial graft. Complete root coverage was obtained. However, at 5 months postoperative the tooth had to be extracted because of a vertical root fracture. With the patient's permission, a small collar of tissue was removed with the tooth. The sample was processed and evaluated histologically. The results revealed areas of regeneration, with new bone, cementum, and connective tissue attachment coronal to the original gingival margin. No bone grafts or guided tissue regeneration membranes were used. This case report confirms that regeneration is possible with subepithelial grafts.- - - - - - - - - - ranking = 0.014833773532833keywords = process (Clic here for more details about this article) |
6/59. Treating internal resorption using a syringeable composite resin.BACKGROUND: Internal resorption is a pathological process initiated within the pulp space with the loss of dentin. It often is described as an oval shaped enlargement of the root canal space and usually is asymptomatic and detectable by routine radiographs. Treatment of internal resorption has included several materials--gutta-percha, zinc oxide eugenol and amalgam alloy. These materials do not provide strength to the tooth structure. CASE DESCRIPTION: A 29-year-old woman was referred to a dental clinic for treatment of a large internal resorptive defect in the coronal and middle one-third of the maxillary left central incisor root with no apparent periapical pathosis, as well as a large periapical radiolucency at the apex of the maxillary left lateral incisor that was associated with a necrotic pulp. The authors used a dual-cure syringable composite resin in conjunction with a bonding agent within the defect to treat it. CLINICAL IMPLICATIONS: This technique seals the dentinal tubules and strengthens the remaining tooth structure. It also improves the outcome of resorptive defects and reduces operators' chair time.- - - - - - - - - - ranking = 0.014833773532833keywords = process (Clic here for more details about this article) |
7/59. Delayed apical healing after apexification treatment of non-vital immature tooth: a case report.We report the endodontic treatment of a non-vital permanent immature tooth in which unexpected complications such as exacerbation of apical periodontitis followed by external root resorption occurred after that the initial stages of the healing process were clinically and radiographically evident. After continued treatment stable repair was obtained.- - - - - - - - - - ranking = 0.014833773532833keywords = process (Clic here for more details about this article) |
8/59. gingival overgrowth as the initial paraneoplastic manifestation of Hodgkin's lymphoma in a child. A case report.BACKGROUND: The purpose of this paper is to present the first case of gingival overgrowth, premature root resorption, and alveolar bone loss, which preceded the diagnosis of a stage IVB Hodgkin's lymphoma (HL) in a 9-year-old boy. methods: The child presented complaining of gingival pain which first appeared 3 months prior. Clinical examination revealed inflamed, hyperplastic gingivae, while x-ray showed premature root resorption and alveolar bone loss. Medical work-up was significant for cervical lymphadenopathy. Gingival biopsy, followed by lymph node resection, was performed twice. RESULTS: Histological examination of both gingival biopsies disclosed a mixed inflammatory infiltrate, while classical Hodgkin's lymphoma of the nodular sclerosis type was diagnosed from the second lymph node biopsy. Chemotherapy was instituted with mustard-vincristine-procarbazine-prednizone and adriamycine-bleomycine-vinblastine-dacarbazine. Remission of the lymphoma was observed with concomitant regression of the gingival overgrowth. CONCLUSIONS: The inflammatory gingival overgrowth, premature root resorption of deciduous teeth, and alveolar bone loss in this case, in conjunction with the regression of gingival overgrowth which followed the completion of chemotherapy, are strongly indicative of a paraneoplastic manifestation of HL. The postulated mechanism for the development of the manifestation is the constitutive activation of the transcription factor NF-kB. The gingival inflammatory reaction was probably further aggravated by the bacterial-stimulated cytokine secretion released by monocytes.- - - - - - - - - - ranking = 3keywords = alveolar (Clic here for more details about this article) |
9/59. Ehlers-Danlos type VIII. review of the literature.Ehlers-Danlos type VIII is a rare disorder characterized by soft, hyperextensible skin, abnormal scarring, easy bruising, and generalized periodontitis with early loss of teeth. To illustrate the clinical dermatological and dental features, we present the case history of a 20-year-old patient who has suffered from poor healing of wounds at the shins and knees since childhood, which have developed into hyperpigmented atrophic scars. In the course of orthodontic treatment during the last 3 years, severe apical root resorption, gingival recession, and loss of alveolar bone were observed. family history was noncontributory for any skin or tooth disorders. The typical clinical signs confirmed the diagnosis of ehlers-danlos syndrome type VIII. As there is no specific treatment for the disorder, management is limited to the symptomatic treatment of the dental disease. It seems advisable to consider carefully the indications for orthodontic treatment in patients with Ehlers-Danlos type VIII syndrome.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
10/59. Decoronation of an ankylosed tooth for preservation of alveolar bone prior to implant placement.A 12-year-old patient sustained avulsions of both permanent maxillary central incisors. Subsequently, both teeth developed replacement resorption. The left incisor was extracted alio loco. The right incisor was treated by decoronation (removal of crown and pulp, but preservation of the root substance). Comparison of both sites demonstrated complete preservation of the height and width of the alveolar bone at the decoronation site, whereas the tooth extraction site showed considerable bone loss. In addition, some vertical bone apposition was found on top of the decoronated root. Decoronation is a simple and safe surgical procedure for preservation of alveolar bone prior to implant placement. It must be considered as a treatment option for teeth affected by replacement resorption if tooth transplantation is not feasible.- - - - - - - - - - ranking = 6keywords = alveolar (Clic here for more details about this article) |
