1/62. Chronic factitial ulcer of chin cured by endodontic (root-canal) surgery for underlying periapical abscess.In a determined search for the cause of a "factitial" ulcer of the jaw, consultation with 3 dentists was required before an underlying periapical abscess was discovered. Within 3 months of endodontic surgery, this ulcer of 12 years duration had completely healed and remains healed. Too often dental infection is neither suspected nor detected as a cause of skin disease.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
2/62. Surgical treatment of a periradicular lesion on an invaginated maxillary lateral incisor (dens in dente).The complex anatomy of invaginated teeth make their root canal treatment difficult. Moreover, this treatment may compromise the future of the tooth if it is destined to support a post-retained coronal restoration. This case reports the successful surgical root canal treatment of an invaginated tooth using a retrograde filling with gutta-percha. After surgical exposure of the root-end and cleaning of the root canal, the gutta-percha was compacted in the root canal which had been coated previously with a zinc oxide-eugenol cement. The gutta-percha was then cold-burnished. Periapical radiographic examination after 1, 2, 3, 6 and 12 months showed periapical healing with osseous formation. This procedure, resulting in minimal loss of hard tissues, permitted subsequent restoration of the tooth.- - - - - - - - - - ranking = 0.2keywords = periapical (Clic here for more details about this article) |
3/62. Dentinal dysplasia type I: report of a case.A case of dentinal dysplasia type I is presented. This rare hereditary disturbance of dentine is characterized by short-rooted teeth with sharp conical apical constrictions, aberrant growth of dentine in the pulp chamber leading to reduced pulp space in permanent teeth and total pulpal obliteration in the primary dentition. Clinical, radiographic and histopathological material from a 7-year-old boy, showing the typical features of this disorder in which teeth are prematurely lost through periapical abscesses, cysts or spontaneous exfoliation, is described. A review of the theories of pathogenesis of this condition is included. Management of patients with dentinal dysplasia is difficult and a discussion of the shortcomings of various treatment strategies, including conventional endodontic therapy, periapical curettage and retrograde root filling, and a preventive regimen, are discussed. In this case, despite diagnosis being made at an early age and the provision of regular dental care, the patient is now losing teeth because of spontaneous abscess formation.- - - - - - - - - - ranking = 0.4keywords = periapical (Clic here for more details about this article) |
4/62. diagnosis and treatment of cutaneous facial sinus tracts of dental origin.BACKGROUND: Cutaneous draining sinus tracts of dental origin often are a diagnostic challenge. A delay in correctly diagnosing these types of lesions can result in ineffective and inappropriate treatment. CASE DESCRIPTION: The authors present five cases of facial lesions that were initially misdiagnosed as lesions of nonodontogenic origin. The correct diagnosis in each case was cutaneous sinus tract secondary to pulpal necrosis and suppurative apical periodontitis. All facial sinus tracts resolved after the patients received nonsurgical root canal therapy. CLINICAL IMPLICATIONS: As patients with cutaneous facial sinus tracts of dental origin often do not have obvious dental symptoms, possible dental etiology may be overlooked. Early correct diagnosis and treatment of these lesions can help prevent unnecessary and ineffective antibiotic therapy or surgical treatment.- - - - - - - - - - ranking = 41.970680743388keywords = periodontitis (Clic here for more details about this article) |
5/62. Metastatic melanoma of the maxilla presenting as a gingival swelling.Malignant melanoma metastatic to the gingiva has been reported only once. We present a case in which the occurrence of melanoma in the gingiva followed extraction of a periapically "abscessed" tooth. Since the initial periapical mass may well have been a metastatic tumor, particularly in a patient undergoing therapy for disseminated malignant disease, the need for biopsy of such lesions is emphasized.- - - - - - - - - - ranking = 0.4keywords = periapical (Clic here for more details about this article) |
6/62. paresthesia of the mental nerve induced by periapical infection: a case report.paresthesia can be a rare complication of infections of dental origin. This article presents a case of anesthesia/paresthesia caused by a periapical infection of the right mandibular second premolar. The sensory disturbance disappeared 2 weeks after conventional endodontic treatment associated with antibiotic therapy. Twelve months later, the tooth was still asymptomatic. The possible mechanisms responsible for paresthesia associated with periapical infection are discussed.- - - - - - - - - - ranking = 1.2keywords = periapical (Clic here for more details about this article) |
7/62. periapical abscess formation and resolution adjacent to dental implants: a clinical report.The vitality of teeth adjacent to dental implants should be considered in the treatment planning of dental implants. Both the restorability of an endodontically treated tooth and the risk of infection of the adjacent implant are important factors in planning for success. Given the illustrated difficulties and difficulties associated with resolving periapical infections of teeth and implants, it is essential to define the vitality of teeth by careful pulp testing and to consider the integrity of existing questionable, endodontically treated teeth before implant treatment. The risk of periapical infection at teeth adjacent to implants must be minimized.- - - - - - - - - - ranking = 0.4keywords = periapical (Clic here for more details about this article) |
8/62. Effect of occlusal trauma on healing of periapical pathoses: report of two cases.AIM: To present two clinical cases and demonstrate that occlusal trauma may affect healing of periapical pathoses. SUMMARY: Two teeth with periradicular disease did not respond successfully to conventional root canal treatment or endodontic surgery. occlusal adjustment was finally performed on both cases. After occlusal adjustment, uncomplicated healing and periapical repair occurred in both cases. The findings in these two cases suggest that occlusal trauma may play a role in the healing of periapical pathoses. KEY learning POINTS: Occlusal trauma is positively correlated with changes in periodontal tissues. Although experiments in animals have shown that application of forces to teeth will not induce further periodontal destruction, we believe that some failures of root canal treatment may be due to the presence of occlusal trauma modulating the responses of inflamed periapical tissues or apical pathoses with persistent infection.- - - - - - - - - - ranking = 1.6keywords = periapical (Clic here for more details about this article) |
9/62. Inferior alveolar nerve paresthesia caused by endodontic pathosis: a case report and review of the literature.Sensory disturbances such as anesthesia, hypoesthesia, hyperesthesia, and paresthesia may be present in the oral cavity, stemming from many local and systemic factors. paresthesia of the inferior alveolar nerve is quite rare because of the unique anatomy of this nerve. Among other effects, periapical lesions can damage the nerve, resulting in paresthesia of its innervated area. Only a few cases of paresthesia caused by these lesions are reported in the literature. In this report we present a case of paresthesia of the right inferior alveolar nerve; discuss the anatomy, pathobiology, and etiology; and suggest that a periapical lesion affecting the lower right second molar (No. 31) may have been the cause. The routine x-rays (intraoral and panorex) and the axial and cross-sectional tomographs of the mandible by means of computed tomography contribute to making this case a good example of nerve injury.- - - - - - - - - - ranking = 0.4keywords = periapical (Clic here for more details about this article) |
10/62. Non-surgical root canal treatment of dens invaginatus type 2 in a maxillary lateral incisor.AIM: To describe the clinical management of an unusual dens invaginatus type 2. SUMMARY: A case of dens invaginatus in a maxillary lateral incisor with a periapical lesion is reported. The patient presented with pain and localized swelling. Despite the complex anatomy and diagnosis of dens invaginatus, non-surgical root canal treatment was performed successfully. Key learning points Dens invaginatus may be presented in many forms, and the aetiology of this phenomenon is not fully understood. Due to abnormal anatomical configuration, dens invaginatus presents technical difficulties in its clinical management. Non-surgical root canal treatment can be performed successfully.- - - - - - - - - - ranking = 0.2keywords = periapical (Clic here for more details about this article) |
