Randomized Controlled Trial
Buccal infiltration versus inferior alveolar nerve block in mandibular 2nd premolars with irreversible pulpitis.
The purpose of this study is to compare the success rates of inferior alveolar nerve block (IANB) and buccal infiltration anesthesia of mandibular second premolar with irreversible pulpitis and to evaluate the level of patient discomfort with these methods. ⋯ Within the limitation of this in vivo study, there was no difference between the efficacies of the buccal infiltration anesthesia and IANB anesthesia in the mandibular 2nd premolar teeth with irreversible pulpitis. Buccal infiltration anesthesia caused more discomfort in the patients compared with the IANB during the administration.

Randomized Controlled Trial
Retreatability of root canals obturated using mineral trioxide aggregate-based and two resin-based sealers.
The aim of this study was to compare the retreatment time and the removal efficiency of different root canal sealers using WaveOne Gold reciproc file system by measuring required time. ⋯ None of the sealers evaluated in this study could completely be removed from the root canals. MTA-based sealer was removed faster than resin-based sealers.
