1/8. Possibilities of preventing osteoradionecrosis during complex therapy of tumors of the oral cavity.In recent years, there has been a dramatic increase in the number of tumors of the head and neck. Their successful treatment is one of the greatest challenges for physicians dealing with oncotherapy. An organic part of the complex therapy is preoperative or postoperative irradiation. Application of this is accompanied by a lower risk of recurrences, and by a higher proportion of cured patients. Unfortunately, irradiation also has a disadvantage: the development of osteoradionecrosis, a special form of osteomyelitis, in some patients (mainly in those cases where irradiation occurs after bone resection or after partial removal of the periosteum). Once the clinical picture of this irradiation complication has developed, its treatment is very difficult. A significant result or complete freedom from complaints can be attained only rarely. attention must therefore be focussed primarily on prevention, and the oral surgeon, the oncoradiologist and the patient too can all do much to help prevent the occurrence of osteoradionecrosis. Through coupling of an up-to-date, functional surgical attitude with knowledge relating to modern radiology and radiation physics, the way may be opened to forestall this complication that is so difficult to cure.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/8. Smokeless tobacco addiction: a threat to the oral and systemic health of the child and adolescent.The use of smokeless tobacco (ST) within the united states has increased greatly in recent years, especially among adolescent boys and young men. Recent national data completed from several large scale studies indicate that 10-12 million Americans use some form of ST. Representing a significant systemic and oral health risk, ST usage can produce a wide range of negative effects on both soft and hard oral tissues. These oral conditions include bad breath, discolored teeth and restorative materials, excessive tooth surface wear (abrasion), decreased ability to taste and smell, gingival (gum) recession, advanced periodontal soft and hard tissue destruction, tooth loss, soft tissue erythema and leukoplakia. Long-term ST usage is directly correlated to an increased risk of cancer of the mouth, larynx, throat and esophagus. Much of the destruction of oral tissues is related to the localization of the tobacco quid; i.e., it is habitually held in only one spot in the mouth. nicotine from ST can activate the sympathetic nervous system thereby significantly increasing heart rate, blood pressure, cardiac stroke volume and output and coronary blood flow. A common misconception is that ST is a 'safe' alternative to smoking cigarettes. Several recent Surgeon General's Reports list ST as being addictive. It is highly possible that ST users will 'graduate' to cigarettes if they eventually conclude that these products are socially unacceptable, inconvenient or out of vogue. Health professionals, educators, parents and schoolchildren need to be informed about the significant health risks associated with ST use.- - - - - - - - - - ranking = 0.021180845871979keywords = mouth (Clic here for more details about this article) |
3/8. Use of microcrystalline collagen for hemostasis after oral surgery in a hemophiliac.A microcystalline collagen hemostat effected rapid hemostasis in dental extractions for a hemophilic patient with a significant level of inhibitor where preoperative transfusion of deficient factor was contraindicated. It appears that MCH can be used safely and effectively for a variety of oral procedures. In addition to its hemostatic properties, the ease with which it can be handled and its adherence make it adaptable for use in locations of limited access. In comparison with currently used materials, such as gelatin foam, it may have wider application and may be of greater benefit in achieving hemostasis in procedures in the oral cavity.- - - - - - - - - - ranking = 0.25keywords = oral cavity, cavity (Clic here for more details about this article) |
4/8. Oral findings in Fanconi's anemia. A case report.A case of fanconi's anemia was referred to the Dental School from the Department of pediatrics. The patient was a 24-year-old male and a product of a consanguineous marriage. His chief complaint was loose and falling teeth, which has started at the age of 16 years. The first teeth to fall out were the first permanent molars followed by mandibular and maxillary anteriors. General examination showed that the patient was of normal intelligence and small for his age. He had no palmar plantar hyperkeratosis and was not diabetic. A total of 19 teeth remained in the mouth, most of them with grade three mobility. The remaining molars and first maxillary premolars had grade three furcation involvement. Most of the teeth had periodontal pockets more than 10 mm deep. Full mouth intraoral periapical radiographs and orthopantomographic views showed severe horizontal bone loss uncommensurate with the patient's age. In view of the patient's history and severe bone loss at an early age, the diagnosis was juvenile periodontitis associated with Fanconi's anemia.- - - - - - - - - - ranking = 0.021180845871979keywords = mouth (Clic here for more details about this article) |
5/8. Anaerobic mediastinitis.Anaerobic bacteria often are neglected in discussions of the bacteriology of mediastinitis. Two cases of anaerobic mediastinitis are reported and the literature in this field is reviewed. Anaerobes are important pathogens in the etiology of mediastinitis secondary to perforation of the esophagus, extension of a retropharyngeal abscess, or extension of cellulitis or abscess of dental origin from the neck. Although anaerobes indigenous to the oral cavity predominate in these cases, there are also a few cases reported involving bacteroides fragilis. The source of the mediastinitis should be considered when antimicrobial therapy is initiated so that appropriate anaerobic coverage can be included when indicated.- - - - - - - - - - ranking = 0.25keywords = oral cavity, cavity (Clic here for more details about this article) |
6/8. Occult dental infection causing fever in renal transplant patients.fever secondary to odontogenic infection following successful renal transplantation is reported in three patients. All three patients initially lacked signs or symptoms localizing to the oral cavity, and two of the three patients did not have x-ray evidence of abscess formation. Two patients received antibiotic therapy without any apparent clinical response, and all three patients responded promptly to surgical extractions. Our patients illustrate that fever can be the only sign of dental sepsis in renal transplant recipients, and tooth extraction as empiric therapy may be necessary. Most important, however, is that the dental pathology responsible for their fever could have been detected and treated prior to transplantation. We recommend pretransplant dental evaluation of all patients with extraction of partially impacted molars and treatment of all periodontal disease and dental caries.- - - - - - - - - - ranking = 0.25keywords = oral cavity, cavity (Clic here for more details about this article) |
7/8. The relationship between dental disease and radiation necrosis of the mandible.Preirradiation panoramic radiographs of forty-six dentate patients were examined for the presence of significant dental disease. The occurrence of necrosis of the mandible after these patients received radiation therapy was then determined. Evidence of a positive association between dental disease present before radiation therapy and subsequent necrosis of the mandible was found (p = 0.09), leading to a recommendation that significant disease be eradicated before irradiation of oral tissues. Two cases are reported to illustrate the complications that can arise in dentate patients following radiation to the oral cavity. Considerable suffering results from bone necrosis, which can be reduced by careful and rational dental diagnosis and treatment.- - - - - - - - - - ranking = 0.0068826739705714keywords = cavity (Clic here for more details about this article) |
8/8. actinobacillus actinomycetemcomitans infection in the oral cavity.An abscess that developed following the extraction of periodontally involved teeth persisted after surgical drainage and ampicillin therapy. Subsequent culture of pus from this abscess gave a pure growth of actinobacillus actinomycetemcomitans which was resistant to ampicillin. Surgical drainage and the use of appropriate antibiotic therapy cleared the infection. The identification of A. actinomycetemcomitans and the types of infection it causes are described. The probable mechanism of infection by the bacterium is discussed. A case that illustrates the importance of the microbiologic examination of pus from dental abscesses is reported.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
