Rheological study of interactions between MHEC and superplasticizers in aqueous solutions for applications in cement industry [PDF]

, 2011
Innovative cement-based materials are characterized today by rather complex formulations. In particular, when cement pastes are considered, their formulation generally includes two different types of polymers: a rheology modifier (RM) (typically a ...

What Outcomes Matter in Vital Pulp Therapy? Current Concepts and Challenges

Australian Dental Journal, EarlyView.
ABSTRACT Vital pulp therapy (VPT) has re‐emerged as a practical and biologically sound alternative for managing deep caries and carious pulp exposures. Although its clinical use is now widespread, the outcomes used to judge the success of VPT remain inconsistent and often difficult to compare across studies.

Effect of calcium source on structure and properties of sol–gel derived bioactive glasses [PDF]

, 2012
The aim was to determine the most effective calcium precursor for synthesis of sol–gel hybrids and for improving homogeneity of sol–gel bioactive glasses. Sol–gel derived bioactive calcium silicate glasses are one of the most promising materials for bone

Influence of Delivery Method of Hydraulic Calcium Silicate Cement‐Based Sealer on Void Formation: A Micro‐Computed Tomography Study

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim of this study was to compare three delivery methods of a hydraulic calcium silicate cement‐based sealer by quantifying voids using the single‐cone technique. Forty‐eight human mandibular molars were instrumented and scanned using micro‐computed tomography.

Discuss the Rationale for Minimally Invasive Endodontics and the Merits and Demerits of the Concept

Australian Endodontic Journal, EarlyView.
ABSTRACT Minimally invasive endodontics (MIE) places emphasis on the conservation of sound tooth structure and viable pulp tissue during endodontic procedures such as root canal treatment (RCTx) and vital pulp therapy (VPT). The use of minimal access cavity designs and conservative canal preparation dimensions have been investigated as a way to improve
