Internal curing of cement pastes by superabsorbent polymers studied by means of neutron radiography [PDF]

, 2017
Autogenous shrinkage is a problem in cementitious materials with a low water-to-binder ratio. When the internal relative humidity decreases due to the ongoing hydration reaction and selfdesiccation, autogenous shrinkage takes place if no external or ...

Frost action in cement paste

Matériaux et Constructions, 1973
An earlier theory of frost action is further developed and its implications considered, particularly with regard to testing. Factors determining durability of paste, dimensions of sample, degree of saturation and rate of cooling are discussed. It is shown that cumulative residual expansion is a good indicator for testing frost resistance: samples can ...

Management of Periodontal Abscesses and Endodontic‐Periodontal Lesions—A Systematic Review

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To evaluate the management of periodontal abscesses and endodontic‐periodontal lesions (EPLs). Methods Seven focused questions addressed outcomes such as pocket depth (PD), bleeding on probing (BOP), tooth loss or ovoid elevation. The literature search covered three electronic databases and manual sources for intervention studies.

Pair distribution function studies in cementitious systems [PDF]

, 2017
The analysis of amorphous/nanocrystalline phase(s) within cement matrices that contain high amounts of crystalline phase(s) is very challenging. Synchrotron techniques can be very useful to characterize such complex samples.1 This work is focused on ...

Effects of Substructure Color and Restoration Thickness on the Final Color of Ultra‐Translucent Zirconia Ceramics

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study aimed to evaluate the effects of substructure color and restoration thickness on the final color of shade‐gradient ultra‐translucent zirconia ceramics. Material and Methods A total of 180 flat‐shaped ultra‐translucent zirconia specimens (5Y‐PSZ) with thicknesses of 0.4, 0.6, and 0.8 mm (n = 60) were fabricated and

The Spot‐Dam Technique: A Protocol for Adhesive Cementation of BOPT Crowns

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The Biologically Oriented Preparation Technique (BOPT) uses vertical tooth preparation without a defined finish line, guided by provisional restorations to shape the gingival emergence profile. Subgingival crown margins inherent to BOPT increase the risk of residual cement and soft‐tissue trauma during adhesive cementation.

Reclaiming Relevance Through Problem‐Driven Interdisciplinary Research

Journal of Management Studies, EarlyView.
Abstract Management studies initially emerged as an applied field, uniquely positioned to tackle practical organizational problems through interdisciplinary research. Over time, however, the field has prioritized abstract theoretical contributions over real‐world engagement, fragmenting into disciplinary silos ill‐equipped to address complex ...
