Exploring the Most Effective Apical Seal for Contemporary Bioceramic and Conventional Endodontic Sealers Using Three Obturation Techniques.

Despite a plethora of studies conducted to date, researchers continue to investigate the best sealer and obturation technique combinations. The aim of this study is to compare the apical seal provided by two bioceramic sealers (Endoseal and Endosequence) with that provided by a calcium hydroxide sealer (Sealapex), and to evaluate the effect of different obturation techniques (cold lateral condensation, continuous wave compaction and single cone) on the apical seal under a stereomicroscope. A total of 110 single-rooted mandibular premolar teeth were decoronated, cleaned and shaped using the Endosequence filing system to tip size 30/0.

Effectiveness of Single Dose Premedication of Piroxicam and Prednisolone on Post Endodontic Pain in One Visit Root Canal Treatment: A Randomized Clinical Trial.

Objective: The objective of this study was to compare the effectiveness of premedication drugs including single dose Piroxicam and Prednisolone in regard to post endodontic pain at different time intervals (24, 48, 72 and 96 hours) after single visit root canal treatment.

Methods: This randomized clinical trial (registration no. NCT04124822) was performed in operative dentistry department of a private clinical institute.
