Background: The addition of bioactive glass (BG), a highly bioactive material with remineralization potential, might improve the drawback of weakening property of mineral trioxide aggregates (MTA) when it encounters with body fluid. This study aims to evaluate the effect of BG addition on physical properties of MTA.
Methods: ProRoot (MTA), and MTA with various concentrations of BG (1, 2, 5 and 10% BG/MTA) were prepared. Simulated body fluid (SBF) was used to investigate the effect of the storage solution on dentin remineralization. Prepared specimens were examined as following; the push-out bond strength to dentin, compressive strength, setting time solubility and X-ray diffraction (XRD) analysis.
Results: The 2% BG/MTA showed higher push-out bond strengths than control group after 7 days of SBF storage. The 2% BG/MTA exhibited the highest compressive strength. Setting times were reduced in the 1 and 2% BG/MTA groups, and solubility of all experimental groups were clinically acceptable. In all groups, precipitates were observed in dentinal tubules via SEM. XRD showed the increased hydroxyapatite peaks in the 2, 5 and 10% BG/MTA groups.
Conclusion: It was verified that the BG-added MTA increased dentin push-out bond strength and compressive strength under SBF storage. The addition of BG did not negatively affect the MTA maturation reaction; it increased the amount of hydroxyapatite during SBF maturation.

To investigate the dislodgement resistance of AH Plus and CeraSeal sealers to root dentin conditioned with Dual Rinse 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP) (DR HEDP) or Triton and to correlate their effects on the organic and inorganic content of the root dentin treated with test irrigants.Sixty single-rooted extracted human teeth were divided into two groups and irrigated with DR HEDP or Triton. These samples were further divided into two subgroups to study the dislodgement resistance of AH Plus and CeraSeal sealers.

Objectives: This study aimed to assess the influence of two endodontic sealers on the bond strength of glass fiber posts using conventional and self-adhesive resin cement through a push-out test.
Methods: Forty central human incisors were randomly divided into four groups (n = 10) based on sealer (epoxy resin- based or calcium silicate-based) and cement (conventional and self-adhesive resin) types: AH Plus (Dentsply De- Trey)/RelyX ARC (3M ESPE), AH Plus/RelyX U200 (3M ESPE), Bio-C Sealer (Angelus)/RelyX ARC, and Bio-C Sealer/RelyX U200. After canal filling and post cementation, roots were sectioned to obtain one specimen per root third.

Background: "Furcation perforation" is a procedural mishap that can compromise endodontic success. An ideal repair material must exhibit strong "dislodgment resistance." Irrigants used during biomechanical preparation may affect the "push-out bond strength (POBS)" of these materials.

Objectives: The objective of this study was to evaluate the dentin tubule penetration of three self-etching adhesive systems and the bond strength of fiber post cementation using standard protocols and ultrasonic activation of the adhesive system.
Materials And Methods: Sixty extracted bovine teeth samples had their canals prepared and the apical thirds filled. Six groups were selected from the total sample.

By conducting push-out tests, the bond behavior between H-shaped steel and concrete under different freeze-thaw (F-T) cycles (including failure modes, bond strength, and bond stress-slip curves) was investigated. The experiment considered one type of concrete (C35), three volumetric stirrup ratios (0.4%, 0.
