1/22. 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.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
2/22. 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.- - - - - - - - - - ranking = 0.2keywords = fracture (Clic here for more details about this article) |
3/22. Management of a horizontal root fracture after previous root canal therapy.This case report concerns a 9-year-old girl who had a horizontal root fracture of her maxillary left central incisor and had root canal therapy performed by her family dentist immediately after the injury. Because of the incomplete canal obturation, the root canal filling material was removed, and calcium hydroxide therapy was initiated. Healing at the fracture site occurred, with hard tissue forming between the root segments. The coronal segment of the root was then obturated with gutta-percha. The patient later had orthodontic treatment with some movement of the coronal segment. Six-year post-treatment follow-up shows apparent clinical and radiographic success. This case illustrates the potential for repair of a horizontal root fracture after endodontic retreatment of the coronal segment and long-term splinting.- - - - - - - - - - ranking = 1.4keywords = fracture (Clic here for more details about this article) |
4/22. Enhanced post crown retention in resin composite-reinforced, compromised, root-filled teeth: a case report.The introduction of an intraradicular composite reinforcing technique, in conjunction with the reestablishment of matching post canal spaces, has allowed compromised, root-filled teeth to be restored with functional, esthetic post crowns. This clinical case report suggests that reconstituted post canals, in accurately adapting to passive, parallel-sided, matching, and well-fitting posts, can enhance the retention of post crowns. Other factors of clinical importance relating to the resin-reinforced technique are discussed, including fracture resistance, depth of polymerization, dentin adhesion, polymerization shrinkage, and coronal microleakage.- - - - - - - - - - ranking = 0.2keywords = fracture (Clic here for more details about this article) |
5/22. 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.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
6/22. 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.- - - - - - - - - - ranking = 0.2keywords = fracture (Clic here for more details about this article) |
7/22. Retrieval of a foreign object from the palatal root canal of a permanent maxillary first molar: A case report.A 12-year-old boy presented with a fractured sewing needle within the palatal root canal of a nonvital permanent maxillary first molar. The patient admitted that he had often placed a sewing needle in the tooth to relieve discomfort associated with it. A minimal amount of tooth structure was removed around the foreign object to facilitate access for K-type files. Under copious irrigation, the files were worked around the object to loosen it. The fractured needle was removed with a tweezers that had long, narrow beaks. Use of this simple technique allowed the object to be removed from the root canal with minimal damage to internal tooth structure.- - - - - - - - - - ranking = 0.4keywords = fracture (Clic here for more details about this article) |
8/22. Use of a tooth-colored post for anterior restorations.The restoration of endodontically treated teeth is still a challenge to the general dentist. Extensive caries or traumatic fracture may result in insufficient coronal tooth structure remaining to support a core. The introduction of fiber post systems in the 1990s has provided dentists with new options for the restoration of the pulpless tooth. This clinical article demonstrates the use of a fiber post and a composite buildup material.- - - - - - - - - - ranking = 0.2keywords = fracture (Clic here for more details about this article) |
9/22. Techniques for immediate core buildup of endodontically treated teeth.Access to the pulp chamber for endodontic treatment is indicated inter alia as a result of extensive caries, trauma to the tooth causing fracture or loss of vitality, requiring restoration of the missing tooth structure. Different approaches and materials are described in the literature for foundation restorations, either with a cast post and core or immediately, with a chairside post-and-core system. This article briefly reviews the current data regarding the microbiologic, prosthetic, mechanical, and periodontal aspects while emphasizing the immediate approach using amalgam, resin composites, and glass ionomers. Factors affecting retention of the post are presented to guide the clinician in selecting a suitable post-and-core system to preserve optimal root structure and prevent root fracture. Three clinical cases are presented in which tooth structure was restored using different techniques: in the first two, provisional acrylic resin shells, one custom made and the other prefabricated, were used to house an amalgam coronal-radicular dowel core, where in the third case, a copper band was used for a composite post-and-core system. All cases emphasize the ease of production and short chairtime in the stages of crown fabrication.- - - - - - - - - - ranking = 0.4keywords = fracture (Clic here for more details about this article) |
10/22. Treatment of a non-vital immature incisor with mineral trioxide aggregate (MTA).- A case of severe crown fracture and luxation in the upper permanent incisors of a 9-year-old boy is reported. The treatment of one of the injured teeth included apexification with calcium hydroxide and endodontic treatment with gutta-percha obturation. The other incisor was also treated with calcium hydroxide, but as there was no apical stop after 3 years of treatment, it was decided to use a new root-end filling material: mineral trioxide aggregate (MTA). At follow-up 12 months later, the tooth was asymptomatic and radiographically showed the initial repair of the radiolucent apical lesion.- - - - - - - - - - ranking = 0.2keywords = fracture (Clic here for more details about this article) |
