Cone-Beam Computed Tomography Analysis of Retreatability of Resin and Bio-ceramic Sealer For Root Canal Treatment: An In Vitro Study.

Root canal retreatment (Re-RCT) cases have shortcomings due to the ineffective removal of the root canal filling material, eventually leading to endodontic failure. This study aims to test the comparative efficacy of retreatment files in removing calcium silicate-based sealer and epoxy resin-based sealer. Thirty-two single-rooted teeth were decoronated at 15 mm and bio-mechanical preparation was performed.

Management of an Open Apex Using a Platelet-Rich Fibrin Membrane as an Internal Matrix and Mineral Trioxide Aggregate as an Apical Barrier: A Case Report.

Apexification is a crucial procedure for achieving apical healing in non-vital teeth with open apices. Traditionally, calcium hydroxide has been used for this purpose, but it has significant drawbacks, including prolonged treatment duration, increased risk of root fracture, and the potential for porous barrier formation. Mineral trioxide aggregate (MTA) has emerged as a superior alternative due to its biocompatibility, faster setting time, and better sealing properties.

Re-evaluation of Microhardness of Mineral Trioxide Aggregate and Biodentine After Removal From Root Using Different Types of Solvents: An In Vitro Study.

Objective This study aimed to evaluate the effects of different solvents on the microhardness of mineral trioxide aggregate (MTA) and Biodentine, which are used in endodontic therapy for their biocompatibility and ability to create a hermetic seal. Methods A total of 150 extracted human single-rooted teeth were selected and sectioned into 4 mm slices. The samples were divided into two groups according to the material used: MTA and Biodentine.
