1/5. The management of ludwig's angina.

    A severe case of ludwig's angina which was treated along the historical lines of surgical decompression is presented. The problem resulting from this approach are discussed together with alternative methods of management. The conclusion is made that surgical decompression as a means of avoiding respiratory obstruction should be abandoned and that tracheotomy should be used.

2/5. Comprehensive therapy of a fusion between a mandibular lateral incisor and supernumerary tooth: case report.

    The term fusion is used to define a developmental anomaly characterised by the union of two adjacent teeth. In the case reported here, clinical and radiographic examinations suggested a unilateral fusion between the mandibular left permanent incisor and a super-numerary tooth. Radiographs showed that the fused teeth had two distinct pulp chambers and canals. A diagnosis of chronic periapical abscess of the supernumerary tooth was made. Before root canal therapy, a periodontal surgical procedure was performed to section the central incisor and its fused supernumerary. Also, odontoplasty was performed on the roots, to establish an anatomy consistent with a normal central incisor. Later, the chronic apical abscess on the supernumerary tooth was instrumented chemo-mechanically, root canal filling was performed and an anterior composite resin restoration was placed. The patient was evaluated for one year after root canal therapy. The tooth was asymptomatic, not exhibiting any pathological root resorption or alveolar resorption, and the anterior composite restoration was intact. Instead of extracting the supernumerary tooth, the application of endodontic, periodontal, and restorative procedures proved to be an alternative treatment.

3/5. Anatomical redesign for the treatment of dens invaginatus type III with open apexes: a literature review and case presentation.

    BACKGROUND: Dens invaginatus is a rare dental anomaly that may give rise to many complex anatomical forms. The complexity of the internal anatomy may create challenges for the complete removal of the diseased pulpal tissue and the subsequent sealing of the canal system. CASE DESCRIPTION: The authors discuss the modification of the internal anatomy under the operating microscope, allowing the clinician better access to treat predictably the canal system with conventional or alternative techniques. CONCLUSION AND CLINICAL IMPLICATIONS: Considering the anatomical variations and the challenges that a dens invaginatus may present, a practitioner may consider a modification of the internal anatomy of the canal system to gain better access for proper instrumentation, disinfection and sealing of the root canal system using conventional or contemporary techniques.

4/5. Conservative endodontic-restorative treatment for a severely damaged and periapically compromised molar: a case report.

    Many teeth with apical involvement show apical external resorption, and become difficult to treat. A patient with a severely damaged, periapically compromised permanent molar was treated successfully with a combination of simple root canal therapy and a conventional amalgam restoration. This method offers an inexpensive and predictable alternative and provides the option for a different restorative approach in the future.

5/5. Endodontic therapy in a postirradiated child: review of the literature and report of a case.

    Exodontia of extremely carious teeth leads to a significant risk of osteoradionecrosis in patients who have undergone radiotherapy. In these patients, endodontic treatment could be an alternative. Successful root canal therapy in a girl who had been irradiated for head and neck neoplasms is reported. The results indicated that use of calcium hydroxide to obturate the root canals is a viable method of postirradiation endodontics in primary teeth.
