1/14. Numb chin syndrome in Ewing sarcoma.The numb chin syndrome consists of unilateral hypesthesia of the chin and lower lip. In adults, it is often associated with metastatic disease to the mandible, base of the skull, or leptomeninges. In children, it has been associated with infiltration of the inferior alveolar nerve by leukemic cells. We describe two cases of numb chin syndrome in children with Ewing sarcoma. In a child with a solid tumor, this symptom seems to have an ominous meaning and should lead to the investigation of progressive skeletal involvement.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/14. Metastatic transitional cell carcinoma of the urinary bladder presenting as a mandibular gingival swelling.Oral cavity metastases mostly originate from the breasts, lungs, or kidneys. Transitional cell carcinoma (TCC), the most frequent malignant tumor of the urinary bladder, rarely metastasizes to the jaws. To the best of our knowledge, only 8 cases of bladder carcinoma have been reported in the English literature to metastasize to the jawbones. A new case of mandibular metastasis of urinary bladder TCC with extension to the gingiva is presented in a 64-year-old white man. The patient was referred for a periodontal infection of the upper right first molar. The clinical examination also showed a gingival swelling located in the lower left premolar region with a hypoasthesia of the left side of the lower lip. The gingival mass was biopsied, and the microscopy showed a mandibular metastatic TCC of the urinary bladder extending to the gingiva. Periodontists should be aware that, although gingival metastases are rare, when they occur they may mimic other local benign pathological conditions.- - - - - - - - - - ranking = 0.08214221063819keywords = jaw (Clic here for more details about this article) |
3/14. Anaesthesia of the right lower hemilip as a first manifestation of multiple myeloma. Presentation of a clinical case.multiple myeloma is a malignant proliferation of plasma cells. It may affect any of various bones, causing osteolytic lesions with a characteristic "punched out" radiographic appearance. The commonest symptom is bone pain. One of the most frequent locations is the mandible. Symptoms of multiple myeloma of the mandible include tumefaction, non-specific pain, tooth mobility and sometimes loss, and paraesthesia of the dental nerve. Here we report a case of multiple myeloma of the mandible which was unusual in that the presenting complaint was anaesthesia of the right lower hemilip.- - - - - - - - - - ranking = 3keywords = mandible (Clic here for more details about this article) |
4/14. Neuropathic complications of mandibular implant surgery: review and case presentations.Injuries to trigeminal nerves during endosseous implant placement in the posterior mandible appear to occur acutely in approximately 5-15 of cases, with permanent neurosensory disorder resulting in approximately 8%. Nerve lateralization holds even higher risks from epineurial damage or ischaemic stretching. Neuropathy from implant compression and drill punctures can result in neuroma formation of all types, and in some cases precipitate centralized pain syndrome. Two patterns of clinical neuropathy are seen to result; hypoaesthesias with impaired sensory function, often seen with phantom pain, and hyperaesthesias with minimal sensory impairment but presence of much-evoked pain phenomena. The clinician must differentiate, through careful patient questioning and stimulus-response testing, those patients who are undergoing satisfactory spontaneous nerve recovery from those who are developing dysfunctional or dysaesthetic syndromes. Acute nerve injuries are treated with fixture and nerve decompression and combined with supportive anti-inflammatory, narcotic and anti-convulsant therapy. Surgical exploration, neuroma resection and microsurgical repair, with or without nerve grafting, are indicated when unsatisfactory spontaneous sensory return has been demonstrated, and in the presence of function impairment and intractable pain.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
5/14. Inferior alveolar nerve paresthesia caused by endodontic pathosis: a case report and review of the literature.Sensory disturbances such as anesthesia, hypoesthesia, hyperesthesia, and paresthesia may be present in the oral cavity, stemming from many local and systemic factors. paresthesia of the inferior alveolar nerve is quite rare because of the unique anatomy of this nerve. Among other effects, periapical lesions can damage the nerve, resulting in paresthesia of its innervated area. Only a few cases of paresthesia caused by these lesions are reported in the literature. In this report we present a case of paresthesia of the right inferior alveolar nerve; discuss the anatomy, pathobiology, and etiology; and suggest that a periapical lesion affecting the lower right second molar (No. 31) may have been the cause. The routine x-rays (intraoral and panorex) and the axial and cross-sectional tomographs of the mandible by means of computed tomography contribute to making this case a good example of nerve injury.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
6/14. Burkitt's lymphoma: an unusual cause of lip numbness.A 38-year-old man was referred by his dental surgeon with a painful swelling in the right mandibular sulcus and an ipsilateral numb lip. Dental infection secondary to caries was initially diagnosed but biopsy revealed this to be a Burkitt's lymphoma. After intense chemotherapy, the patient is still in remission three years later. This case is a reminder that malignancy should always be high on a clinician's list of differential diagnoses of jaw swelling associated with neurological abnormalities and prompt referral is essential.- - - - - - - - - - ranking = 0.041071105319095keywords = jaw (Clic here for more details about this article) |
7/14. Arteriovenous malformation of the mandible--a case report.Both arteriovenous malformations (AVMs) and solitary bone cysts of the mandible are uncommon lesions. The latter can be considered fairly innocuous but AVMs require careful management. The following is a description of a case where an arteriovenous malformation of the mandible presented with mental nerve paraesthesia. However, radiographically the features appeared to be consistent with a solitary bone cyst. It is important for clinicians in both a primary and secondary care setting to be aware that this type of lesion can have life threatening complications.- - - - - - - - - - ranking = 6keywords = mandible (Clic here for more details about this article) |
8/14. Proposal for a standardized protocol for the systematic orofacial examination of patients with Hereditary Sensory Radicular Neuropathy.AIM: To apply a standardized protocol for the orofacial evaluation of two adult siblings (one male and one female) with Hereditary Sensory Radicular Neuropathy (HSRN) that presented with dental problems. SUMMARY: The systematic evaluation consisted of (a) clinical questionnaire; (b) radiographs [orthopantomography and computarized tomography (CT)]; (c) orofacial psychophysical tests (pain, thermal, mechanical and electrical sensation); and (d) histology of gingiva and pulp (optical and transmission electronic microscopy). The female patient had complete insensitivity to orofacial pain and partial facial heat sensitivity, and received dental treatment without anaesthesia or pain. She had a severe and painless jaw infection due to pulp necrosis in tooth 37. The male patient had partial insensitivity to orofacial pain and required anaesthesia for dental treatment. Histological examination of gingivae and pulpal tissue revealed an altered proportion of unmyelinated and myelinated sensory nerve fibres. KEY learning POINTS: * patients with HSRN may present with significant, silent dental disease. * A standard protocol is helpful when evaluating such patients. * If the opportunity arises, evaluation of pulp tissue may reveal an altered proportion of myelinated and unmyelinated nerve fibres. This may avoid the more estabilished sural nerve biopsy.- - - - - - - - - - ranking = 0.041071105319095keywords = jaw (Clic here for more details about this article) |
9/14. mandible metastasis as the initial manifestation of breast carcinoma--report of a case.A case is presented in which the only positive subjective and clinical findings were numbness of the lower lip and chin, generalized tooth mobility with dull pain, and swelling of the right lower jaw. After an appropriate and careful workup, in conjunction with other medical colleagues, a definitive diagnosis of adenocarcinoma of breast metastasis to the mandible was made, which was confirmed by a histopathologic examination. Radiographs disclosed radiolucent change with an irregular and a moth-eaten appearance in the mandibular trabeculation and loss of the lamina dura of several teeth. As this case demonstrates, the diagnosis of metastatic disease of the jaws requires a high degree of diagnostic astuteness, because of the many possible clinical signs and symptoms which can be nonspecific and can resemble diseases of an inflammatory origin. Accordingly, a histologic evaluation is essential in establishing a definitive diagnosis. The case report emphasizes the need for consideration of metastatic disease in the differential diagnosis of unknown oral lesions, especially in the mandible.- - - - - - - - - - ranking = 2.0821422106382keywords = mandible, jaw (Clic here for more details about this article) |
10/14. Unusual periodontal findings in an AIDS patient with Burkitt's lymphoma. A case report.This report deals with a case of AIDS-related Burkitt's lymphoma in which some of the earliest findings were dental and periodontal in nature. The patient presented initially with painless and extremely loose teeth accompanied by progressive paresthesia of the lower jaw. Unique radiographic findings included extensive periodontal ligament space widening and bulbous, granuloma-like lesions about the apices of the teeth. These findings were associated with progressive tumor infiltration of the mandible and do not appear to be related to other reports of aggressive periodontitis associated with impaired immunologic functions in AIDS patients.- - - - - - - - - - ranking = 1.0410711053191keywords = mandible, jaw (Clic here for more details about this article) |
