Comparative evaluation of remaining dentin thickness using single file, two file, and multiple rotary file system - An in vitro CBCT study.

Context: Endodontic success hinges on a multifactorial interplay, with meticulous canal shaping, proper disinfection, and three-dimensional obturation being paramount. Among these factors, the amount of dentin remaining after instrumentation directly influences the biomechanical resilience and longevity of the tooth.

Aims: This study aims to evaluate the impact of various rotary instrumentation systems, including single-file, two-file, and multiple-file configurations, on the remaining dentin thickness (RDT) following canal preparation.

Comparative evaluation of push-out bond strength of bioceramic and epoxy sealers after using various final irrigants: An study.

Aim: The aim of the study is to compare the push-out bond strength of bioceramic and epoxy sealers after using various final irrigants.

Materials And Methods: Hundred single-rooted teeth were divided into two groups ( = 50) according to the sealer used: Group A: Bio C (bioceramic sealer), Group B: Dia-Proseal (epoxy sealer). Each group was subdivided into five subgroups ( = 10) according to the final irrigation protocol: Group A1 and B1 - 5% glycolic acid (GA), Group A2 and B2 - 17% GA, Group A3 and B3 - 0.
