Phosphoric acid treatment enhances adaptation of glass-ionomer cement to bioceramic sealer-conditioned dentin.

Background: This study evaluated the interface between fresh eugenol/bioceramic sealer-conditioned coronal dentin and high-viscous glass-ionomer cement (HVGIC), treated with various dentin conditioners (saline, 10% polyacrylic acid, and 37% phosphoric acid).

Materials And Methods: Standard endodontic access preparation and instrumentation were done in 21 freshly extracted mandibular molar teeth in this study. Teeth were divided into two interventional groups ( = 9/group), based on the type of sealer (zinc oxide eugenol [ZOE]/bioceramic [BioRoot RCS] sealer) used for obturation.

Root canal isthmi and interorifice distance in human permanent teeth of an Indian subpopulation using cone-beam computed tomography: A retrospective cross-sectional study.

Objective: The aim of the study was to evaluate the prevalence of root canal isthmus (RCI) and measure the interorifice distance (IOD) between the root canals. Additionally to correlate IOD with the RCI in human permanent teeth using conebeam computed tomography (CBCT) in an Indian sub-population (Chennai).

Materials And Methods: A total of 5881 teeth from 280 CBCT full mouth scans were analyzed.
