RESUMEN
The aim of this study was to assess the effect of ibuprofen sustained release (SR) oral premedication on the efficacy of buccal infiltration (BI) with intraoperative and postoperative pain after single-visit root canal treatment. Sixty patients diagnosed with symptomatic irreversible pulpitis and apical periodontitis in mandibular molar were divided into two groups. Group SR received ibuprofen SR 800 mg and group PL received placebo capsule 1 h before 3.6 mL articaine BI injection. Pain was recorded using a modified visual analogue scale and postoperatively at intervals 6, 24 and 48 h. Group SR showed a significantly higher anaesthetic success rate (73.3%) compared to group PL (46.7%) (p < 0.05). Intraoperative and postoperative pain was significantly higher in group PL compared to group SR (p < 0.05). Premedication of ibuprofen SR improved the efficacy of primary BI in mandibular molars with symptomatic irreversible pulpitis and decreased postoperative pain at 6 and 48 h.

The success rate of fractured instrument retrieval varies because it is dependent mainly on several factors including the visibility of the fractured instrument, the length of the fractured instrument in relation to the curvature of the canal and the techniques applied to each case. This review aims to update the present status on removal of fractured instruments to identify factors and variables that could affect the success of fractured instrument retrieval based on both the preparation techniques and the instrument retrieval techniques. On the other hand, future directions of fractured instrument retrieval should focus on management of nonvisible fractured instruments since the removal of those instruments is deemed unpredictable with the current techniques, whereas the removal of visible fractured instruments is considered predictable now. Another possible direction of it is that there might be no more instrument fracture due to possible significant changes in the root canal preparation technique which may dispense with the use of rotary instruments.
