Efficacy of buccal piroxicam infiltration and inferior alveolar nerve block in patients with irreversible pulpitis: a prospective, double-blind, randomized clinical trial.

Objectives: This randomized clinical trial aimed to assess the effectiveness of buccal infiltration with piroxicam on the anesthetic efficacy of inferior alveolar nerve block (IANB) with buccal infiltration in irreversible pulpitis, with pain assessed using the Heft-Parker visual analogue scale (HP-VAS).

Materials And Methods: This study included 56 patients with irreversible pulpitis in mandibular molars, randomly distributed between 2 groups ( = 28). After evaluating the initial pain score with the HP-VAS, each patient received IANB followed by buccal infiltration of 2% lignocaine with adrenaline (1:80,000).

Comparative evaluation of fluoride release and re-release and recharge potential of Zirconomer Improved and Cention.

Background: The cariostatic action associated with fluoride-releasing restorative materials is mainly attributed to a sustained release of fluoride. This research aims on comparing Cention N and Zirconomer Improved fluoride release and re-release.

Methods: Test materials were grouped into two categories containing 15 samples each.
