1/49. zirconium oxide post and core system for the restoration of an endodontically treated incisor.

    Due to their enhanced optical properties (eg, translucency, value, chroma), ceramic systems can provide natural aesthetics for restorations placed in the anterior segment. In endodontically treated teeth with stained dentin, however, the use of translucent ceramic materials may be contraindicated unless the underlying discoloration can be masked. This article describes the use of a zirconium oxide post and core system with an all-ceramic crown for the restoration of an endodontically treated anterior tooth. This contemporary system allows optical and mechanical requisites to be resolved simultaneously.

2/49. The dentine-bonding of a fractured non-vital anterior tooth.

    This case illustrates an alternative management of a fractured non-vital incisor using adhesive techniques to avoid the disturbance of, and offer protection to, successful endodontic treatment. The rationale for the maintenance of sound tooth structure and the minimisation of coronal leakage, while adequately restoring aesthetics, is discussed.

3/49. Carbamide peroxide whitening of nonvital single discolored teeth: case reports.

    patients who present with a single discolored tooth represent a significant restorative challenge. These case reports describe an economic and conservative treatment option for these patients. The situations presented demonstrate techniques for bleaching with carbamide peroxide in a traditional nightguard or with an inside-outside technique to achieve acceptable esthetic results on isolated nonvital discolored teeth. Although these techniques may not be effective in all cases, they do not compromise or eliminate any future treatment options.

4/49. Forced eruption: a multidisciplinary approach for form, function, and biologic predictability.

    There are several treatment options for patients with coronal fractures, subgingival caries perforations, and root resorption. Frequently, forced eruption is not considered, although in many cases of single-rooted teeth, forced eruption is the "gold standard" for producing an esthetic result without jeopardizing periodontal support for adjacent teeth. Sufficient tooth length, achieved through forced eruption, ensures the periodontal health of the "biologic width" and crown margin and thus a successful restorative outcome.

5/49. 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.

6/49. Nonvital tooth bleaching: a 2-year case report.

    A discolored, nonvital maxillary right central incisor was bleached with sodium perborate and water, used as a "walking" bleach. An excellent result was obtained, proving the efficiency of both the intracoronal bleaching technique and the materials employed. A clinical evaluation performed 2 years later revealed that the tooth was slightly stained but esthetically satisfactory.

7/49. A cautionary tale. Case report.

    A healthy 26 year old female underwent unsuccessful surgery for an incorrectly diagnosed sebaceous cyst in the cheek. Eventually the problem was traced to a non-vital tooth 24. When the tooth was treated endodontically, the situation resolved in one week.

8/49. Root extrusion, a practical solution in complicated crown-root incisor fractures.

    Implants and fixed and removable prostheses are very successful in replacing missing units but their cost can be inhibitory to a number of patients. In addition fixed and removable prostheses can be destructive to sound abutment teeth and can result in damage to dental and soft tissue. This report describes the restoration of a tooth with a complicated incisor crown-root fracture that extended below both the gingival cuff and the alveolar crest, by using remaining tooth tissue. The restoration was completed after root extrusion with a cast post, diaphragm and core, and porcelain crown.

9/49. Use of an existing post to rerestore an endodontically treated tooth with a new post-and-core complex and crown: a case report.

    Replacement of a post-and-core restoration that has failed because of caries or fracture presents a restorative challenge to the general dentist. This case report describes a new technique that enables the utilization of an unremovable preexisting post in the fabrication of a new post-and-core complex. This complex served as a foundation for a restoration that restored form and function to the patient's dentition.

10/49. Implant failures associated with asymptomatic endodontically treated teeth.

    BACKGROUND: Endosseous root-formed implants occasionally fail to osseointegrate. Causes of failure include infection, overheating of the bone, habitual smoking, systemic disease, transmucosal overloading, excessive surgical trauma and implant placement adjacent to teeth demonstrating periapical pathology. CASE DESCRIPTION: In this article, the authors present another possible cause of implant failure. The cases of four patients who received endosseous root-formed implants are discussed. Each patient demonstrated signs of infection after initial implant placement. The common factor in each failing implant was its placement adjacent to an asymptomatic endodontically treated tooth with no clinical or radiographic evidence of pathology. CLINICAL IMPLICATIONS: These patients demonstrate the importance of evaluating and possibly retreating or extracting adjacent endodontically treated teeth before placing implants.
