title: Comparison of prophylactic and on-demand diflunisal for pain management of patients having one-visit endodontic therapy.
abstract: To determine whether the posttreatment prophylactic use of diflunisal (Dolobid 500) would be more effective than the on-demand use of diflunisal in reducing endodontic posttreatment pain, the current open-label, randomized study was undertaken. After one-visit nonsurgical endodontic therapy, 100 patients with asymptomatic teeth having either vital-inflamed pulp, pulpal necrosis, or pulpal necrosis with periapical radiolucent lesion were randomly given either prophylactic diflunisal (two tablets immediately at the conclusion of the visit, then four tablets to be taken in the schedule of one every 8 to 12 hours for pain if needed) or on-demand diflunisal (same dosage schedule; pills to be taken only if needed). The outcome showed that compared to the on-demand usage, the posttreatment prophylactic administration of diflunisal resulted in a statistically significant reduction in the number of episodes of endodontic posttreatment pain that required analgesic intervention. It appears from the results of this study that the posttreatment prophylactic use of diflunisal is significantly more effective than the on-demand usage of diflunisal in reducing endodontic posttreatment pain for one-visit endodontic therapy with all types of originally asymptomatic endodontic conditions. Further studies are necessary to determine whether pretreatment prophylactic deflunisal would be more effective, and also the effectiveness of prophylactic diflunisal in reducing posttreatment pain in presenting symptomatic cases and for cases treated in multiple visits.
