TL;DR: Aliphatic carbons, from the polymerization reactions, especially in Dycal and TheraCal, were found to mask the other components and showed that Ca in the surface layer could vary from 0 to 18%, depending on the material.

TL;DR: A critical review of recent advances in the chemistry and engineering of MO-based biocomposites is presented, highlighting the role of interactions at the interface and the techniques by which these can be studied.
Abstract: Metallo-oxide (MO)-based bioinorganic nanocomposites promise unique structures, physicochemical properties, and novel biochemical functionalities, and within the past decade, investment in research on materials such as ZnO, TiO2, SiO2, and GeO2 has significantly increased. Besides traditional approaches, the synthesis, shaping, structural patterning, and postprocessing chemical functionalization of the materials surface is inspired by strategies which mimic processes in nature. Would such materials deliver new technologies? Answering this question requires the merging of historical knowledge and current research from different fields of science. Practically, we need an effective defragmentation of the research area. From our perspective, the superficial accounting of material properties, chemistry of the surfaces, and the behavior of biomolecules next to such surfaces is a problem. This is particularly of concern when we wish to bridge between technologies in vitro and biotechnologies in vivo. Further, be...

TL;DR: It is suggested that hDPSCs show suitable biological response in terms of cell viability, cell proliferation, and cell migration when in contact with extracts from NeoMTA Plus, MTA Repair HP, and Biodentine.

TL;DR: The results show that the three capping materials are biocompatible, maintain viability and stimulate proliferation, migration and differentiation in a key dental stem cell population.
Abstract: The aim of the study was to evaluate the effects of the capping materials mineral trioxide aggregate (MTA), calcium hydroxide (CH) and BiodentineTM (BD) on stem cells from human exfoliated deciduous teeth (SHED) in vitro SHED were cultured for 1 - 7 days in medium conditioned by incubation with MTA, BD or CH (1 mg/mL), and tested for viability (MTT assay) and proliferation (SRB assay) Also, the migration of serum-starved SHED towards conditioned media was assayed in companion plates, with 8 μm-pore-sized membranes, for 24 h Gene expression of dentin matrix protein-1 (DMP-1) was evaluated by reverse-transcription polymerase chain reaction Regular culture medium with 10% FBS (without conditioning) and culture medium supplemented with 20% FBS were used as controls MTA, CH and BD conditioned media maintained cell viability and allowed continuous SHED proliferation, with CH conditioned medium causing the highest positive effect on proliferation at the end of the treatment period (compared with BD and MTA) (p<005) In contrast, we observed increased SHED migration towards BD and MTA conditioned media (compared with CH) (p<005) A greater amount of DMP-1 gene was expressed in MTA group compared with the other groups from day 7 up to day 21 Our results show that the three capping materials are biocompatible, maintain viability and stimulate proliferation, migration and differentiation in a key dental stem cell population
