RESUMO
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.
