Tissue reactions after experimental luxation injuries in immature rat teeth.

Immature permanent teeth often develop complications after luxation injuries. The pathology and the degenerative processes of the complications, however, are not well understood. In this study, we histologically examined the long-term reactions of immature rat teeth after standardized luxation injuries delivered in our previously developed experimental model. The upper first molars of 3-week-old male Wistar rats weighing 50-60 g were pushed horizontally toward the palate to cause a constant amount of dislocation. The follow-up changes of the luxated molars were studied up to 56 days after the trauma. Soon after the trauma, the periodontium had irregular fibers, degenerated cells, hemorrhage and edema in various places. After 12 h, a cell free area appeared in the palatal periodontium. In the alveolar bone and on the surface of the root, resorption occurred one day and 5-7 days after injury respectively. Although the damage in the periodontium and alveolar bone was gradually repaired, the root resorption, especially in the palatal cervical region, continued throughout the experimental period. In the most cases, the dental pulp did not seem to be damaged immediately after the trauma. By the 3rd day after injury, however, displacement of odontoblasts into the dentinal tubules was observed in many teeth. Moreover, formation of irregular dentin was observed in some teeth after 7 days. These changes of the pulp tended to disappear in the later stages of the experiment.

Emergency dental management of a patient with von Willebrand's disease.

A patient with von Willebrand's disease presenting for dental treatment requires thorough evaluation prior to the determination of a proper course of treatment. In this case report, a patient with von Willebrand's disease presented to the emergency room with dental trauma. A modified treatment plan, taking into account the severity of the patient's systemic illness and the need for medical management, yielded successful results.

Autotransplantations and loss of anterior teeth by trauma.

The loss of anterior teeth by trauma has usually been corrected by orthodontic or prosthetic means. In some specific cases, however, the skeletal and dental relationship may contraindicate the use of space-closure mechanics. Autotransplantation of teeth, successfully depicted in many clinical studies, can help to reduce the severity of orthodontic cases complicated by traumatized anterior teeth. A case report is presented to stress both the indications and limitations of such treatment.

Transient apical breakdown following subluxation injury: a case report.

Transient apical breakdown has been reported to occur in cases in which a periapical radiolucency develops and resolves without treatment following luxation injury. Diagnostic errors are inevitable if periapical breakdown is used as the sole criterion or as an overriding criterion in the decision to initiate root canal treatment. A clinical case report is presented in which transient apical breakdown occurred after a subluxation injury. The threshold to sensitivity tests increased yet sensitivity remained positive with the appearance of the periapical radiolucency. The decision was made not to initiate root canal treatment in spite of the radiographic appearance periapically. At the 10-month recall the tooth remained responsive to sensitivity tests and the apical radiolucency had disappeared.

Delayed endodontic and orthodontic treatment of cross-bite occurring after luxation injury in permanent incisor teeth.

A case is presented in which combined endodontic and orthodontic therapy was performed in traumatically injured teeth 12 months after an accident. Calcium hydroxide treatment was used to halt any possible resorption during orthodontic treatment. The teeth were repositioned in a desirable manner without any complication by orthodontic treatment. Root canal obturation was accomplished after the completion of active orthodontic treatment. Recall examination 12 months after completion of root canal treatment showed clinical and radiographic evidence of healing.

Bilateral pulmonary aspiration of intact teeth following maxillofacial trauma.

Tooth aspiration is one of the rare sequelae of dental trauma. When this does occur, the right bronchus is usually involved in adults due to the anatomical configuration. In this unusual case, two teeth were aspirated with one entering each lung. While the outcome from cases of aspiration of foreign bodies is usually favourable, this case serves to illustrate one of the possible unfavourable consequences.

Micro-scooter induced dental trauma: a case report.

There has been a remarkable increase in the popularity of micro-scooters over the past few years. This has brought with it an astonishing rise in the number of associated injuries. Highlighted here is a case report which outlines the dental injuries associated with the use of a micro-scooter.

Emergency dentures and esthetics.

Accidents occur in life and when they affect the dentition, whether natural, artificial, or a combination, they can result in a feeling of dread and despair in the patient. The thought of appearing not only in public with business and social acquaintances, but also in private with family members can be reprehensible. This article discusses the use of visible light-cured denture base materials that can be used to alleviate the fear these patients display in being exposed to socio-esthetic intercourse when becoming suddenly partially edentate. The method of use and three patients' photographic essay presentations are discussed.

Achieving optimal esthetics in a patient with severe trauma: using a multidisciplinary approach and an all-ceramic fixed partial denture.

UNLABELLED: The treatment of traumatic injuries can be difficult, especially when the patient's expectations are too high or unreasonable. Such cases require extremely clear communication with the patient before beginning the case, including an explanation of the final results, based on the patient's goals. Taking over a case from another colleague adds more complications and requires that close attention is paid to the reason for the original dissatisfaction between the former dentist and patient to avoid repeating the same mistakes. Clinically, patients with thin, fragile gingiva are extremely challenging if they require a fixed partial denture in the esthetic zone since the most common material, a ceramometal bridge, requires infragingival margins; if any recession occurs, a catastrophic esthetic failure will result. The case presented here underscores all these special issues. Proper multidisciplinary management, good patient communication, and the use of an all-ceramic fixed partial denture system can provide an excellent final result. CLINICAL SIGNIFICANCE: Replacing teeth in the esthetic zone is complicated, especially when trauma has caused severe damage to the surrounding bone and gingiva. Satisfying a demanding patient requires a multidisciplinary approach and psychological management, as are exemplified in this article.
