ABSTRACT
This case report presents a surgical case in which an accessory branch of the mental nerve exited the mandible distal and slightly superior to the mental foramen. Careful manipulation of the surgical site allowed proper identification of the mental nerve, and the accessory branch and permanent nerve damage was avoided.

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.

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 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. In addition, the profession has disregarded much of the research that shows many recommended storage media damaging to avulsed teeth. This article reviews the pertinent research on avulsed teeth and recommends a new treatment philosophy of avulsed teeth that delineates 10 treatment categories based on the type of storage medium used, the length of extraoral time, and the stage of development of the root apex.

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.

The treatment of advanced periodontal breakdown as a result of an associated endodontic lesion continues to challenge the practitioner. Two cases of teeth with endodontic pathologic conditions that required apical surgery are presented. On raising the flap, no buccal cortical plate was found, significantly lowering the prognosis of the surgery. A barrier membrane was used in addition to the apical surgery, which on postoperative follow-up appears to have resulted in the reestablishment of the buccal cortical plate.

To determine whether a relatively large dose of oral dexamethasone given for a short period of time would be effective in reducing endodontic interappointment pain, the current double-blind, placebo-controlled study was undertaken. After the visit for instrumentation, 40 patients with asymptomatic teeth having vital-inflamed pulps were randomly given either dexamethasone (3 tablets of 4 mg each) or a dextrose placebo identical in appearance (same dosage schedule). The outcome showed that the oral administration of dexamethasone resulted in a statistically significant reduction in endodontic interappointment pain at all three time periods evaluated, that is, at 8 hours, 24 hours, and 48 hours (p less than 0.01). It appears from the results of this study that this dosage schedule of oral dexamethasone is sufficient to significantly reduce endodontic interappointment pain for teeth with asymptomatic vital-inflamed pulps. Further studies are needed for teeth with other endodontic pulpal-periapical conditions and for symptomatic teeth.
