Chemical Stability and Bond Strength of Endodontic Sealers Exposed to Acidic, Alkaline and Protein‐Rich Environments: An In Vitro Investigation

Australian Endodontic Journal, EarlyView.
ABSTRACT The sealing performance of endodontic sealers may be influenced by environmental factors such as pH and blood‐derived proteins. This in vitro study evaluated the effects of pH variation and protein contamination on calcium ion (Ca2+) release and push‐out bond strength (BS) of a calcium silicate‐based sealer (Bio‐C Sealer) and an epoxy resin ...

Preoperative Periapical Status and Outcomes of Vital Pulp Therapy: A Systematic Review and Meta‐Analysis

Australian Endodontic Journal, EarlyView.
ABSTRACT This systematic review has investigated whether the preoperative periapical radiographic status (PPRS) is a predictor of VPT success/survival. Four databases were searched for studies published from inception to November 2024. The studies' characteristics were tabulated, and a meta‐analysis was performed to evaluate the correlation between ...

Influence of Drying Protocol on the Setting and Crystalline Phase Formation of Calcium Silicate‐Based Sealers

Australian Endodontic Journal, EarlyView.
ABSTRACT The objective of this study was to assess the hydration, crystalline structure, and setting of bioceramic ready‐to‐use and powder/liquid sealers in dry and wet root canal dentine. Thirty‐two single‐rooted human teeth were embedded in acrylic resin and sectioned into 2‐mm segments.

Selective Root Canal Retreatment: A Scoping Review and Metasynthesis by Thematic Analysis

Australian Endodontic Journal, EarlyView.
ABSTRACT Selective root canal retreatment preserves well‐filled canals by treating only roots showing clinical or imaging evidence of failure, providing a minimally invasive alternative to conventional full retreatment. This scoping review, supported by metasynthesis through thematic analysis, synthesised clinical and imaging evidence in multirooted ...
