The use of Bioceramics as root-end filling materials in periradicular surgery: a literature review [PDF]
, 2018 Introduction: Periradicular surgery involves the placement of a root-end filling following root-end resection, to provide an apical seal to the root canal system. Historically several materials have been used in order to achieve this seal.

Investigation of Cement, Mineral and Chemical Additive Interactions in Micro Scales
Düzce Üniversitesi Bilim ve Teknoloji Dergisi, 2021 Self-compacting concretes (SCC), a new type of concrete, were realized with the development of polycarboxylate-based chemical additives. The interaction of these additives with the powder materials in the nano and micro scales affects the fresh and ...

Influence of Drying Protocol on the Setting and Crystalline Phase Formation of Calcium Silicate-Based Sealers. [PDF]
Aust Endod JABSTRACT 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.
