1/81. Laser Doppler flowmetry: an aid in differential diagnosis of apical radiolucencies.The case of a patient having 2 teeth with associated apical radiolucencies that responded to conventional pulp tests is presented. A decision was made to reexamine the patient at intervals rather than perform root canal treatment. During a recall visit, use of an available laser Doppler flowmeter allowed detection of blood flow within the affected teeth. A diagnosis of periapical cemental dysplasia (cementoma) was made.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
2/81. Canalis sinuosus mimicking a periapical inflammatory lesion.A case is presented in which an anatomical feature, canalis sinuosus, manifested as a periapical radiolucency on an upper canine. This may have been interpreted as an inflammatory lesion and led to the patient receiving inappropriate treatment had a further radiograph not been taken. The incisive foramen and mental foramen are well known anatomical features which may mimic periapical inflammatory lesions but it is less common for a neurovascular canal to manifest as a periapical radiolucency on an upper canine.- - - - - - - - - - ranking = 7keywords = periapical (Clic here for more details about this article) |
3/81. 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 = 2keywords = periapical (Clic here for more details about this article) |
4/81. ameloblastoma--a diagnostic problem.A 50-year-old female was referred by her dental practitioner. She had a periapical radiolucency associated with the lower right second premolar tooth. The tooth was root treated and subsequently apicected. Tissue curetted at the time of surgery was shown to be a solid ameloblastoma which was managed initially by marginal excision. Histopathological examination of the resection specimen demonstrated tumour at the inferior margin. A segmental resection of the mandible with an immediate reconstruction using a free tissue transfer of the iliac crest was therefore performed. The case shows the need for vigilance in dealing with periapical pathology and underlines the importance of sending all tissue specimens for histopathological analysis.- - - - - - - - - - ranking = 2keywords = periapical (Clic here for more details about this article) |
5/81. Computerized tomography in the management and follow-up of extensive periapical lesion.Radiographs are good diagnostic aids in endodontics, although they have limitations. The purpose of this article is to discuss the use of computerized tomography in differential diagnosis, treatment planning, follow-up and overall clinical management of complex periapical lesions. A clinical case of an extensive symptomatic periapical lesion of the upper jaw is presented, in which the use of computerized tomography allowed evaluation of the true extent of the lesion and its spatial relationship to important anatomical landmarks. Computerized tomography also provided specific information about the type of lesion and the degree of bone repair which had taken place 18 months after non-surgical treatment had been completed.- - - - - - - - - - ranking = 6keywords = periapical (Clic here for more details about this article) |
6/81. Periapical cemental dysplasia: case report.The authors present a case of periapical cemental dysplasia affecting the mandibular left canine, with vital pulp, in a 43-year-old black female patient, an occurrence that follows the classical cases found in the literature. The need of a careful history, clinical and radiographic exams and vitality tests are emphasized in order to reach the correct diagnosis of this disease.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
7/81. hemangioma of the mandible presenting as a periapical radiolucency.A case of an hemangioma of the mandible in a 53-yr-old female patient is presented. The lesion was removed, and no atypia or mitotic cells were found. The excision was curative, and the overall prognosis was excellent. A differential diagnosis of radiolucent periapical lesions of the mandibular symphysis is presented.- - - - - - - - - - ranking = 5keywords = periapical (Clic here for more details about this article) |
8/81. The implant periapical lesion: four case reports and review of the literature.postoperative complications have been identified with implant failure in conjunction with the increased use of root-type implant restorations. The failure of osseointegrated dental implants primarily occurs as a result of peri-implantitis and occlusal overload. Less frequently reported failures, however, have been attributed to implant periapical lesions. The etiology and treatment modalities for such lesions have been speculated throughout the literature. This article discusses possible etiologies of and treatment for implant periapical lesions based on the existing literature and four case reports.- - - - - - - - - - ranking = 6keywords = periapical (Clic here for more details about this article) |
9/81. Treatment of a human transosseous mandibular defect by guided bone regeneration.The treatment of through-and-through human periapical lesions by barrier membrane techniques has not been reported in the periodontal literature. However, periodontists frequently perform this treatment. The authors present a case that demonstrates radiopacity after regeneration surgery of a human periapical transosseous mandibular defect, suggesting local bone regeneration. The surgical technique performed in this case was based on the principles of guided bone regeneration using a demineralized freeze-dried bone membrane (DFDBM). The bone membrane acted as an efficient barrier that excluded the nonosteogenic tissue. Radiographic findings demonstrated bone fill after 8 months.- - - - - - - - - - ranking = 2keywords = periapical (Clic here for more details about this article) |
10/81. Reversible and irreversible painful pulpitides: diagnosis and treatment.The foregoing clinical evidence indicates that when pain is severe, or when mild to moderate pain is present with a previous history of pain in the aching tooth, with or without periapical radiolucency, the tooth is in the IRPP category. Treatment dictates endodontic therapy or extraction. On the other hand, when clinical evidence indicates that the pain is mild or moderate with no previous history of pain, normal pulp vitality, and there is no positive percussion sign, the pulp is in the RPP category. Treatment dictates indirect or direct pulp capping in teeth with or without periapical radiolucency. The success rate favours teeth with no periapical radiolucency, 98%; in teeth with periapical radiolucency the success rate is less favorable, 43%. Efforts should be made to maintain pulp vitality. Endodontic therapy can always be done, if in time the pulp develops necrosis.- - - - - - - - - - ranking = 4keywords = periapical (Clic here for more details about this article) |
