The Effect of Dentin Bonding and Material Thickness on the Flexural Properties of a Lithium-Disilicate Glass-Ceramic.

J Adhes Dent 2021 Jul;23(4):309-318

Purpose: Thanks to adhesive techniques and strengthened glass ceramics, ultrathin bonded occlusal veneers have been recently introduced. However, since a universally accepted thickness limit for ultrathin ceramics has yet to be established, their resistance to fracture needs to be better investigated.

Using Proanthocyanidin as a Root Dentin Conditioner for GIC Restorations.

J Dent Res 2021 Jul 14:220345211018182. Epub 2021 Jul 14.

Melbourne Dental School, The University of Melbourne, Carlton, VIC, Australia.

Glass ionomer cements (GICs) are considered the material of choice for restoration of root carious lesions (RCLs). When bonding to demineralized dentin, the collapse of dentinal collagen during restorative treatment may pose challenges. Considering its acidic nature and collagen biomodification effects, proanthocyanidin (PAC) could be potentially used as a dentin conditioner to remove the smear layer while simultaneously acting to biomodify the dentinal collagen involved in the bonding interface.

Silane Heat Treatment Could Eliminate the Hydrofluoric Acid Etching of Lithium Disilicate Overlays: A Four-Year Follow-Up.

Case Rep Dent 2021 22;2021:9961621. Epub 2021 Jun 22.

Department of Conservative Dentistry, Faculty of Dental Medicine, Medical University of Sofia, Georgi Sofiiski 3 Str., Sofia, Bulgaria.

A four-year follow-up of a novel silane heat treatment method for bonding lithium disilicate overlays to tooth structures without hydrofluoric acid etching of the ceramic surface is presented in this case report. Silane heat treatment modifies the silane layer and thus enhances resin ceramic bond strength without hydrofluoric acid etching. The standard ceramic preparation technique prior to bonding silicate ceramics to tooth structure is hydrofluoric acid etching and applying a silane coupling agent, followed by dental adhesive.

Spectrochim Acta A Mol Biomol Spectrosc 2021 Jul 2;262:120144. Epub 2021 Jul 2.

State Forensic Science Laboratory, Department of Home, Government of Chhattisgarh, Raipur 492001, Chhattisgarh, India.

In the present work, we report the adsorption of the methylene blue (MB) dye from an aqueous solution employing resin immobilized gold nanocomposites (R-AuNCs) assisted surface-enhanced infrared absorption (SEIRA) spectroscopy. The appropriate adsorption isotherm models, including the Langmuir, Freundlich, and Temkin are tested to reveal the interactive behavior between the adsorbent (R-AuNCs) and adsorbed (MB). Interestingly, Fourier transform infrared spectroscopy (FTIR) in combination with R-AuNC materials could be another approach through which the analysis of adsorption-desorption of MB on the surface of nanocomposite adsorbents is possible in a more precise way with high sensitivity and adsorptivity.

Energy Decomposition Analysis of the Adhesive Interaction between an Epoxy Resin Layer and a Silica Surface.

Langmuir 2021 Jul 9;37(28):8417-8425. Epub 2021 Jul 9.

Institute for Materials Chemistry and Engineering and IRCCS, Kyushu University, Nishi-ku, Fukuoka 819-0395, Japan.

We investigate the adhesive interaction energy (Δ) between an epoxy resin and a silica surface using pair interaction energy decomposition analysis (PIEDA), which decomposes Δ into four components: electrostatic (Δ), exchange repulsion (Δ), charge-transfer (Δ), and dispersion (Δ) energies based on quantum chemistry. Our previous study with PIEDA showed that synergistic effects of Δ and Δ are critical at the interface between an epoxy resin fragment and a hydrophilic surface. The present study is designed to show in detail that the synergistic effects are significant at the interface between an epoxy layer model consisting of 20 epoxy monomers and a hydrophilic silica surface.

Bis[2-(Methacryloyloxy) Ethyl] Phosphate as a Primer for Enamel and Dentine.

J Dent Res 2021 Jul 8:220345211023477. Epub 2021 Jul 8.

Centre for Oral, Clinical and Translational Sciences, Faculty of Dentistry, Oral and Craniofacial Sciences, King's College London, London, UK.

Dental resin composites are commonly used in the restorative management of teeth via adhesive bonding, which has evolved significantly over the past few decades. Although current self-etch bonding systems decrease the number of clinical steps, the acidic functional monomers employed exhibit a limited extent of demineralization of enamel in comparison to phosphoric acid etchants, and the resultant superficial ionic interactions are prone to hydrolysis. This study evaluates the etching of primers constituted with bis[2-(methacryloyloxy) ethyl] phosphate (BMEP) of dental hard tissue, interfacial characteristics, and inhibition of endogenous enzymes.

[Preparation and application of chiral silica gel spheres based on L-glutamic].

Se Pu 2021 Jun;39(6):607-613

School of Chemistry and Chemical Engineering, Yunnan Normal University, Kunming 650500, China.

Inorganic mesoporous silica gel spheres, which possess sufficient mechanical strength, thermal stability, and mobile phase endurance, are the most important and widely used materials for column packing in high performance liquid chromatography (HPLC). However, amorphous silica gel is generally reported as an inorganic chiral silica gel, and spherical all-inorganic chiral silica gel has not been reportedly used as the chiral stationary phase for HPLC. In this paper, inorganic spherical mesoporous silica gel was used in the method of polymerization-induced colloid aggregation (PICA), with silica sol as the raw material and L-glutamic acid (L-Glu) as the chiral monomer, to obtain mixed spheres of urea-formaldehyde resin and colloidal silica in a chiral environment.

Cranberry Juice Extract Rapidly Protects Demineralized Dentin against Digestion and Inhibits Its Gelatinolytic Activity.

Materials (Basel) 2021 Jun 29;14(13). Epub 2021 Jun 29.

Department of Oral & Craniofacial Sciences and Center of Excellence in Mineralized Tissues, School of Dentistry, University of Missouri-Kansas City, 650 E 25th St., Kansas City, MO 64108, USA.

Improving the longevity of composite restorations has proven to be difficult when they are bonded to dentin. Dentin demineralization leaves collagen fibrils susceptible to enzymatic digestion, which causes breakdown of the resin-dentin interface. Therefore, measures for counteracting the enzymatic environment by enhancing dentin collagen's resistance to degradation have the potential to improve the durability of dental composite restorations.
