1/14. Deposition of calcified tissue around an overextended gutta-percha cone: case report.CASE REPORT: Root canal treatment was performed in a mandibular right second premolar with a periapical lesion and apical resorption. The root canal was prepared with K-files using the step-back technique and 3% NaOCl as an irrigant; during obturation gross overfilling of gutta-percha occurred. The tooth was permanently restored with a post and core along with a crown. Although healing of the periapical lesion occurred and the patient reported that he was symptom-free, the tooth was extracted after 4 years because of a subgingival root fracture. Following extraction the tooth was examined with SEM. The examination revealed the presence of newly formed calcified tissue at resorption sites on the root apex. This newly formed tissue extended from the surface of the root around the apex to the extruded gutta-percha cone to which it was well adapted, forming a bridge between the cone and the root.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
2/14. Inferior alveolar nerve paresthesia relieved by microscopic endodontic treatment.We experienced two cases of inferior alveolar nerve paresthesia caused by root canal medicaments, which were successfully relieved by microscopic endodontic treatment. In the first case, the paresthesia might have been attributable to infiltration of calcium hydroxide into the mandibular canal through the root canals of the mandibular left second molar tooth. In the second case, the paresthesia might have been attributable to infiltration of paraformaldehyde through the root canals of the mandibular right second molar tooth. The paresthesia was relieved in both cases by repetitive microscopic endodontic irrigation using physiological saline solution in combination with oral vitamin B12 and adenosine triphosphate.- - - - - - - - - - ranking = 0.0039690392887737keywords = alveolar (Clic here for more details about this article) |
3/14. Inferior alveolar nerve injury caused by thermoplastic gutta-percha overextension.Injuries to the inferior alveolar nerve following trauma resulting in a mandibular fracture are well documented and are a well-known risk when surgical procedures are planned for the mandible in the region of the inferior alveolar canal. Such injuries are relatively rare following endodontic therapy. This article reports a case of combined thermal and pressure injury to the inferior alveolar nerve, reviews the pathogenesis of such an injury and makes suggestions for its management.- - - - - - - - - - ranking = 0.0055566550042832keywords = alveolar (Clic here for more details about this article) |
4/14. Management of arsenic trioxide necrosis in the maxilla.Historically, pulp-necrotizing agents were commonly used in endodontic treatments. They act quickly and devitalize the pulp within a few days. However, they are cytotoxic to gingiva and bone. If such an agent diffuses out of the cavity, it can readily cause widespread necrosis of gingiva and bone, which can lead to osteomyelitis of the jaws. Although the use of arsenic trioxide can cause severe damage to surrounding tissues, producing complications, it is still used in certain areas in the world. This article presents and discusses two cases of tissue necrosis and their surgical management. These cases showed severe alveolar bone loss in the maxilla, which affected the patients' quality of life and limited the restorative possibilities. As dentists, we should be aware of the hazardous effects of arsenic trioxide and should abandon its use. Because of its cytotoxicity, there is no justification for the use of arsenic trioxide in the modern dental practice.- - - - - - - - - - ranking = 0.00079380785775475keywords = alveolar (Clic here for more details about this article) |
5/14. Antroliths: survey of the literature and report of a case.In the present report, a case with a radiopaque mass within the right maxillary sinus antrum is presented, and the clinical/radiographic features of the lesion are provided. The patient's dental history has revealed extrusion of calcium hydroxide into the periapical area during a previous endodontic treatment. This finding has underscored the need to discuss the potential role of endodontic materials in the development of calcified tissues within the adjacent body cavities.- - - - - - - - - - ranking = 0.5keywords = periapical (Clic here for more details about this article) |
6/14. Successful treatment of a ruptured infected aneurysm of the lumbar artery with transcatheter embolization.We report a patient who had an infected aneurysm of the lumbar artery caused by prolonged psoas abscess-forming spondylitis due to methicillin-resistant staphylococcus aureus and who was treated successfully with transcatheter arterial embolization. This case suggests that an infected aneurysm can be treated successfully by transcatheter arterial embolization in emergent situations (active bleeding or septicemia) even if surgery is contraindicated.- - - - - - - - - - ranking = 0.00030002787505101keywords = abscess (Clic here for more details about this article) |
7/14. Mental nerve paresthesia associated with endodontic paste within the mandibular canal: report of a case.The present study describes a case of endodontic paste (Endomethasone) penetration within and along the mandibular canal from the periapical zone of a lower first premolar following endodontic treatment of the latter. The clinical manifestations comprised anesthesia of the right side of the lower lip and paresthesia of the gums in the fourth quadrant, appearing immediately after endodontic treatment. The lip anesthesia was seen to decrease, with persistence of the gingival paresthesia, after 7 months.- - - - - - - - - - ranking = 0.5keywords = periapical (Clic here for more details about this article) |
8/14. breast abscess following central venous catheterization.We describe a case of late perforation of the right internal mammary vein by a central venous catheter inserted via the left subclavian vein. This resulted in extravasation of parenteral nutritional fluid and breast abscess formation. Delay in reaching the diagnosis was experienced in this case and in two cases previously reported. The clinical presentation was similar in all three cases with good early function of the catheters followed by symptoms of chest pain and signs of inflammation in the breast contralateral to the site of insertion of the central venous catheter. Confirmation of correct placement of the central venous catheter must be sought in any patient who develops these symptoms or signs so that the delay in diagnosis we experienced can be avoided. This may be obtained by a lateral or oblique chest radiograph or by contrast studies if preferable.- - - - - - - - - - ranking = 0.0015001393752551keywords = abscess (Clic here for more details about this article) |
9/14. Assessment of endodontically treated teeth for restorative procedures.This article describes a case report in which cementation of cast posts and cores in endodontically treated upper central incisors resulted in extrusion of zinc phosphate cement into the periapical tissues. This case demonstrates the necessity for careful evaluation of existing endodontic therapy before proceeding with the restorative phase of treatment. Some primary indications for endodontic re-treatment are suggested.- - - - - - - - - - ranking = 0.5keywords = periapical (Clic here for more details about this article) |
10/14. Complications from extravasated retroperitoneal barium: case report and review of the literature.Extravasation of barium into the retroperitoneum is an uncommon complication of radiologic examinations of the gastrointestinal tract. It may occur during evaluation of either the upper or lower tract. A case is presented in which the result was abscess formation, a potential delayed complication of duodenal perforation and retroperitoneal extravasation of barium. In this case, medical treatment was successful.- - - - - - - - - - ranking = 0.00030002787505101keywords = abscess (Clic here for more details about this article) |
