Randomized Controlled Trial
Efficacy of mepivacaine-tramadol combination on the success of inferior alveolar nerve blocks in patients with symptomatic irreversible pulpitis: a randomized clinical trial.
To compare the success of an inferior alveolar nerve block (IANB) after injecting a combination of mepivacaine and tramadol or mepivacaine alone in patients with symptomatic irreversible pulpitis (SIP) in mandibular permanent molars. ⋯ The combination of mepivacaine-tramadol achieved similar success rates for IANB when compared to mepivacaine 2% epinephrine 1 : 100 000. There was no significant difference in the anaesthetic efficacy between the control and experimental solutions, and none of the solutions tested were completely successful.

Randomized Controlled Trial
Effect of maintaining apical patency on endodontic pain in posterior teeth with pulp necrosis and apical periodontitis: a randomized controlled trial.
To evaluate the association between apical patency and post-operative pain in posterior teeth with pulp necrosis and apical periodontitis. ⋯ Maintenance of apical patency during chemomechanical preparation had no significant influence on post-operative pain in posterior teeth with necrotic pulps and apical periodontitis.
