1/36. 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 = canal (Clic here for more details about this article) |
2/36. 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 = 1keywords = canal (Clic here for more details about this article) |
3/36. 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 = 0.25keywords = canal (Clic here for more details about this article) |
4/36. A new bacterial species associated with failed endodontic treatment: identification and description of actinomyces radicidentis.OBJECTIVE: This report describes 2 endodontic patients who had persistent signs and symptoms after conventional root canal treatment. The aim of this study was to determine what microorganisms were present in the root canals of the teeth with failed endodontic therapy. STUDY DESIGN: After removal of the root fillings, the canals were sampled by advanced microbiological techniques and the isolates were characterized by various tests. RESULTS: bacteria, which grew in pure cultures, were isolated in each case. The bacteria were similar to each other and were classified as actinomyces on the basis of phylogenic and phenotypic evidence. The bacteria were different from others within the genus, thus warranting designation as a new species, actinomyces radicidentis. CONCLUSIONS: The 2 cases of endodontic failure were infected with A radicidentis, a new actinomyces species. This bacterium joins a restricted group of other microorganisms that have been associated with failure of root canal treatment.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
5/36. 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 = 0.5keywords = canal (Clic here for more details about this article) |
6/36. Generalized odontodysplasia--a case report.odontodysplasia is a relatively uncommon condition that can affect both primary and permanent dentition. It is characterized by defective formation of both enamel and dentin, with enlarged pulp chambers and root canals with open apices. It is usually a localised condition where one or few teeth may be involved. Sometimes, an entire quadrant or more than one quadrant may be involved but generalized involvement is extremely rare. An interesting case of a generalized odontodysplasia affecting both primary and permanent dentition in an eight year old girl is presented here.- - - - - - - - - - ranking = 0.25keywords = canal (Clic here for more details about this article) |
7/36. Management of teeth with open apices and necrotic pulps with single visit apexification: 3 representative cases.apexification is the most widely accepted procedure for the treatment of nonvital immature teeth. Single visit apexification is less time consuming, more economical and an easily acceptable technique with the aim of inducing the formation of a hard tissue barrier, thus allowing proper condensation of gutta percha in the root canal. Factors considered during this procedure are: i. debridement of root canal minimizing the infection and filling the root canal space with resorbable calcification inducing material i.e. Ca(OH)2. ii. Minimal mechanical intervention to maintain the integrity and vascularity of apical region. Once filled, Ca(OH)2 was not changed again and the treated tooth was examined only radiographically till the desired apical closure was achieved. Three representative cases treated with this single visit apexification technique are discussed here. In all the cases successful apical closure of different types was achieved. Treatment was then concluded with gutta percha obturation in all the cases with successful follow up.- - - - - - - - - - ranking = 0.75keywords = canal (Clic here for more details about this article) |
8/36. 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 = 1.5keywords = canal (Clic here for more details about this article) |

10/36. Endodontic and periodontal treatments of a geminated mandibular first premolar.AIM: To describe a rare case of gemination involving a mandibular first premolar. SUMMARY: The complex morphology of geminated teeth renders their endodontic and periodontal management difficult. Root canal and periodontal treatments were performed on a geminated mandibular first premolar with three canals. Clinical examination showed two separated crowns with united roots. Radiographically, two distinct pulp chambers with two joined and a third independent canal were seen. Conventional root canal treatment resulted in complete healing of the apical lesion. However, the occurrence of a vertical fracture led to the extraction of the mesial segment. At the follow-up visit, the distal segment was clinically healthy and continued to satisfy functional demands.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
