1/135. erythema nodosum of dental origin.

    This paper describes the case of a patient who had erythema nodosum which disappeared following teeth extraction. ( info)

2/135. 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.

3/135. 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.

4/135. apexification & apexogenesis.

    When there is pulpal involvement of permanent teeth with incompletely formed roots, techniques for the induction of apical closure should be completed before endodontic therapy is begun. apexification is a method of inducing a calcified barrier at the apex of a nonvital tooth with incomplete root formation. Apexogenesis refers to a vital pulp therapy procedure performed to encourage physiological development and formation of the root end. ( info)

5/135. 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. ( info)

6/135. 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. ( info)

7/135. 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.

8/135. 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. ( info)

9/135. Endodontic radiographs: realities and illusions.

    Several case reports show how, on occasion, radiographs fail to disclose important realities. The illusions that are presented radiographically have the potential to misdirect diagnosis and treatment as well. ( info)

10/135. A suspected periradicular scar: treat or not?

    This paper presents an unusual case of a tooth with multiple adjacent endodontic problems. The diagnosis was complicated by a bony scar that untypically was located around the apex of one of the teeth. ( info)
