Endodontic applications of guided tissue regeneration in endodontic surgery.

This paper is intended to provide an overview of different endodontic applications in guided tissue regeneration. It is our expectation that using these techniques, where applicable, will increase endodontic surgical success. We have described six different clinical conditions including external resorption, root perforation, dehiscence, palatal grooves, oblique root fractures, and large periapical lesions. We believe the use of guided tissue regeneration techniques will allow us to predictably treat teeth that otherwise might be extracted.

Endodontic applications of guided tissue regeneration in endodontic surgery.

There are several possible causes of failure following nonsurgical and surgical endodontic treatments. Many of the causes of these failures can be attributed to the presence of endodontic-periodontic bone loss around roots. The development of guided-tissue regeneration (GTR) procedures in periodontal therapy has let to the successful treatment of some types of periodontal bone loss. These GTR procedures can be adapted for use in endodontic surgery to produce success in cases that previously presented a poor prognosis. this study categorizes all of the different clinical situations in which GTR procedures can be used to treat endodontically related bone loss. Case reports of several categories are presented.

The access box: an ah-ha phenomenon.

Proper access is the basis for all endodontic therapy. This article highlights a teaching tool that powerfully demonstrates to all students and dentists the concept of proper access.

Management of tooth avulsion in the school setting.

Tooth avulsion is a widespread problem for school nurses and school health care personnel. Over two million teeth are avulsed every year in the United States, often during school activities. Almost all avulsed teeth can be saved if stored properly and then replanted by a dentist. All of the known methods and devices for the storage, preservation, and transportation of avulsed teeth are reviewed in this article. Based on this review, specific recommendations are made to the school nurse for saving avulsed teeth.

Avulsed teeth. Management during anesthesia induction, surgery.

It is not known how often teeth are inadvertently knocked out in the operating room during intubation or surgery. When it occurs, it can be very disturbing to the operating room personnel and the patient when he or she recovers from the surgery. Research has shown that most avulsed teeth can be saved by replanting them within 15 to 30 minutes, aligning and splinting them into proper position, and instituting appropriate follow-up care. Because a dentist cannot easily be found in this time period, a system designed specifically to preserve the teeth can be used to provide optimum care in these situations. By using such a system, the physician can proceed with the surgery knowing that all the appropriate measures have been taken to save the knocked-out tooth.

Treatment of tooth avulsion in the emergency department: appropriate storage and transport media.

Teeth that have been accidentally avulsed can be preserved, reconstituted, and replanted with an excellent long-term retention prognosis. The mechanisms for this process are now well understood. The most biologic methods for preserving and storing avulsed teeth are presented so that the emergency physician can choose appropriate modalities for treating patients who present with this problem.

The treatment of avulsed teeth.

More than 2 million teeth are accidentally avulsed each year in the United States. Most of the victims are children. Almost all of these teeth can be saved if the proper treatment is instituted. Regardless of the frequency with which it occurs, every pediatric health care provider must be prepared for patients who have avulsed teeth. By instituting the proper treatment, the provider may help to save a victim's tooth, thus saving the family and child the expense of dental treatment and the possible psychologic problems associated with false teeth. Each health care provider should take the following steps: 1. Inform all health care personnel that avulsed teeth can and should be saved. 2. Teach all health care personnel what action should be taken if a tooth is avulsed. 3. Fabricate or purchase tooth-preserving devices such as the Emergency Tooth Preserving System, which can safely store, preserve, and transport avulsed teeth. 4. Place these tooth-preserving devices at strategic locations such as in emergency kits or at nurses' stations.

Treatment of tooth avulsion by nurses.

More than 90% of the 2 million teeth avulsed each year in the United States can be saved if the proper treatment is instituted. Storage in a tooth-preserving medium can sustain the life of the tooth for 12 hours. An avulsed tooth that has dried out should be soaked in Hank's solution before replantation to reconstitute degenerated cells.
