1/14. Glanzmann's thrombasthenia. Report of two oral surgical cases using a new microfibrillar collagen preparation and EACA for hemostasis.Glanzmann's thromboasthenia is a rare congenital platelet disorder characterized by a prolonged bleeding time, a qualitative platelet defect, and severe hemorrhagic episodes. patients with this disorder have been managed by administration of blood and blood components (most recently, platelet-rich plasma and platelet concentrates) to control hemorrhage resulting from trauma or surgical procedures. The two case reports presented here illustrate the use of a local hemostatic agent (microfibrillar bovine collagen, Avitene) and a systemic fibrinolytic inhibitor (epsilon aminocaproic acid, Amicar) to control postoperative hemorrhage secondary to elective extraction of teeth. The clinical results demonstrate excellent postoperative hemostasis and support recent in vitro observation of platelet adherence to the collagen preparation. This provides an alternate therapeutic modality in the management of patients with Glanzmann's disease and possibly other disorders of platelet function.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/14. 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 = 1keywords = extraction (Clic here for more details about this article) |
3/14. Healing of maxillary sinusitis of odontogenic origin following conservative endodontic retreatment: case reports.Because of the anatomical proximity, infection of posterior upper teeth can spread into the maxillary sinus. When confronted with a large persistent periapical lesion on a posterior maxillary root-treated tooth, the practitioner should question the quality of the previous endodontic treatment, evaluate the impact of the potential causes of failure and consider, in the majority of cases, the conservative non-surgical retreatment instead of extraction or periapical surgery of the dental element. This paper reports two cases of healing of extensive periapical bone destruction and of the co-existing sinus pathology of odontogenic origin after non-surgical endodontic retreatment of previously root-treated upper molars. Misconceptions concerning the role of epithelium in the periapical lesion are discussed. Also, emphasis is put on the need of precise radiological diagnosis, pre-operatively as well as post-operatively to ascertain healing and to avoid unnecessary delay in the appropriate management of these patients.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/14. ehlers-danlos syndrome: historical review, report of two cases in one family and treatment needs.Easy bruising in EDS is common, and is frequently the presenting complaint. Bleeding from the gingiva following toothbrushing or dental extraction is another manifestation. There are many oral manifestations of this syndrome.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/14. Cleidocranial dysostosis: a multidisciplinary approach to treatment.To ensure eruption of the dentition in patients with cleidocranial dysostosis, close collatoration between the oral surgeon and the orthodontist is essential to determine the sequence of extraction, the teeth to be ligated, the preferred technique of ligation, and the approach for surgical exposure.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/14. 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 = 1keywords = extraction (Clic here for more details about this article) |
7/14. Further observations on dental parameters of trigeminal and atypical facial neuralgias.One hundred thirty-one patients with primary trigeminal neuralgia and 77 patients with atypical facial neuralgia or pain were treated by oral surgical procedures, with complete or almost complete pain remission in 88% of the cases and without persistent residual anesthesias, dysesthesias, or dysalgesias. The following conditions were related to patients' pain perceptions: cavities in alveolar bone at tooth extraction sites, bone fistulas, periodontal infections, and maxillary sinus infections draining into alveolar bone. The bone cavities and fistulas mentioned above were usually not visualized by standard x-ray diagnostic procedures, and their detection required a new diagnostic approach which is described. Microbiologic findings indicated involvement of a mixed, variable flora in the above conditions. Histopathologic observations of scrapings from involved bone showed a variable incidence of bone necrosis, predominantly chronic inflammatory cell populations and fibrous tissue.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/14. role of the dentist in trigeminal neuralgia.It is well known that people with idiopathic trigeminal neuralgia sometimes have teeth unnecessarily extracted. It is less well known that pain which seems to be due to idiopathic trigeminal neuralgia is occasionally due to dental causes. For this reason it is suggested that such cases should be given very careful dental and oral examination before the commencement of drug therapy or surgery. Such an examination must be meticulous and may be tedious as well as time consuming. It should therefore be done by a dentist who is specially interested in pain and who is preferably associated with a centre for pain relief. A few cases may then have their pain relieved by such procedures as fillings, extractions or occlusal adjustment. In all cases the neurologist or neurosurgeon will face his responsibility more secure in the knowledge that all possible peripheral causes have been eliminated. Moreover, patients with idiopathic trigeminal neuralgia may have difficulty maintaining a satisfactory standard of oral hygiene, both before and after treatment. They should therefore have careful attention paid to this as soon as possible.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/14. 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 = 3keywords = extraction (Clic here for more details about this article) |
10/14. 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 = extraction (Clic here for more details about this article) |
