Comparative evaluation of push-out bond strength and mode of failure of three different obturating materials: An study.

Aim: This research aimed to assess the push-out bond strength (PBS) to dentin of three distinct obturation materials inside the root canal and identify the failure mechanism.

Materials And Methods: The research used 30 undamaged human mandibular premolars. The specimens were randomly assigned to three groups, each employing a different sealer ( = 10).

Effect of various disinfectant solutions on the tensile strength of gutta-percha using the rapid sterilization technique.

Context: Gutta-percha (GP) gets contaminated during handling. It becomes imperative to ensure GP is sterile before placement in root canal space.

Aims: The aim of the study was to evaluate and compare the tensile strength of GP treated with four different disinfectant solutions: 3% sodium hypochlorite (NaOCl), amla juice (AJ), (AV) juice, and pancha tulsi (PT).
