Stem cells in dentistry and medicine: the dentist's role.

Research has shown that teeth are a source of high quality stem cells that may be used for the treatment of medical and dental disease. The discovery that odontogenic tissues are a source of adult stem cells has opened up a new role for dentists in the field of medicine. Dentists are positioned to become one of the key providers of stem cells, and as a result, their linkage with the medical field will become very intimate.

Endodontic treatment of reimplanted avulsed teeth.

By using an appropriate storage system such as a Save-A-Tooth and having knowledge of appropriate treatment options, an avulsed tooth can be reimplanted with the greatest chance of success. Using the different categories of avulsed teeth discussed in this article as a guide, the clinician can determine the most applicable course of treatment. If endodontic treatment is based on the clinical condition of the pulp and PDL cells, the chance of success following reimplantation is improved.

Anatomy of the pulp-chamber floor.

Locating the number and position of orifices on pulp-chamber floors can be difficult. This is especially true when the tooth being treated is heavily restored, malposed, or calcified. After evaluating 500 pulp chambers of extracted teeth, new laws for finding pulp chambers and root-canal orifices are proposed.

Management of sports-related tooth displacements and avulsions.

Between 500,000 and 750,000 dental injuries occur each year during sports activities in the United States. Twenty percent of these are tooth displacements: extrusive or lateral luxations, intrusions, or exarticulations. Such injuries pose serious problems and the manner in which they are treated can affect the prognosis.

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.

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.

New philosophy for the treatment of avulsed teeth.

The success rate of replanted avulsed teeth has been low. This poor success rate results from the use of only one treatment regimen. This treatment regimen, replantation as quickly as possible regardless of circumstances, ignores much of the dental research that shows this regimen to not be efficacious.

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.

AANA journal course: update for nurse anesthetists--treatment of avulsed teeth in the operating room.

Teeth that are avulsed in the operating room either during intubation, extubation, or other orally related procedures must be treated immediately in order to provide the best opportunity for success following replantation. New treatment methods have been developed that can significantly increase the success of replanted avulsed teeth. These methods utilize special pH balanced reconstituting fluids, cushioning devices, topical fluorides, and antibiotics that permit the storage of avulsed teeth for up to 96 hours with good success following replantation.

Modern treatment of avulsed teeth by emergency physicians.

New research has shown that the incidence of success of replanted avulsed teeth can be greatly increased by differentially diagnosing and treating them according to the length of extraoral time and the physiological width of the apical foramen. A specific treatment regimen has been presented that will give the physician the information necessary to maximize the success of replanted avulsed teeth that may be seen.

Management of dental injuries.

Dental-related injuries, which range from chipped teeth to fractured jaws, are among the most common injuries seen in schools. This article describes the various injuries and provides guidelines, for the nurse's actions at the scene, to ensure the greatest potential for successful treatment. Guidelines are also given for informing other school and associated health personnel about dental emergencies.

Preserving avulsed teeth for replantation.

We performed a retrospective study of 34 replanted avulsed teeth placed in an EPTS before replantation. Even when extraoral time was 120 minutes or more, 91 percent of the teeth showed excellent or moderate success for follow-up periods ranging from three to 30 months. We think that the success of a replanted avulsed tooth is increased by use of a prefabricated tooth preserving and protecting system as described.

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.

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.

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.
