Fiber-reinforced composites in fixed prosthodontics —Quo vadis?
Fiber-reinforced composite (FRC) materials were introduced to dentistry more than five decades ago [1]. Following extensive research and product development, it took more than twenty-five years until FRCs were first indicated as a reconstruction material for fixed dental prostheses (FPDs) [2 –4]. Early FRC FPDs were used in the design of full coverage crown retainers but the rationale for using indirect crown-retained FRC FPDs were questioned when it became evident that the longevity of the FRC FDPs was not as favourable as porcelain-fused-to-metal FDPs [5].

Fracture resistance of molar teeth with mesial-occlusal-distal (MOD) restorations
Filled MOD restorations show near-complete recovery of tooth strength relative to the newly prepared, unfilled state. The present study examines the underlying mechanics of this recovery by more closely quantifying the mode of splitting fracture from the cavity base. By understanding the role of specific cavity dimensions on fracture resistance, useful clinical guidelines concerning MOD morphologies are formulated. (Source: Dental Materials)

Sol –gel-derived bioactive glass nanoparticle-incorporated glass ionomer cement with or without chitosan for enhanced mechanical and biomineralization properties
Glass ionomer cement (GIC) is a tooth-colored material introduced by Wilson and Kent [1] in the late 1960s. GIC is set based on a reaction between a fluoroaluminosilicate-based glass powder and an acidic liquid primarily composed of polyacrylic acid. These substances bond chemically to the tooth structure via a carboxyl (from GIC)-calcium (from enamel or dentin) interaction and release fluoride ions for a relatively long period, which is a beneficial anticariogenic property [2,3]. Along with the above advantages, GIC has been used as luting cement, a restorative material or a base and liner before a final direct or indirec...

Evaluation of alternative monomers to HEMA for dental applications
2-Hydroxyethyl methacrylate (HEMA) is the most frequently used hydrophilic monofunctional monomer that can be found in various dental materials such as dental adhesives, resin-modified glass ionomer cements (RMGICs) or luting composites [1,2]. Depending on the etching process, dental adhesives can be classified into two main categories: total-etch (TEAs) and self-etch adhesives (SEAs) [3 –5]. When using TEAs, the dental hard tissues are typically etched using a phosphoric acid gel prior to the infiltration of an adhesive resin. (Source: Dental Materials)

Poly(amido amine) and calcium phosphate nanocomposite remineralization of dentin in acidic solution without calcium phosphate ions
Patients with dry mouth often have an acidic oral environment lacking saliva that provides calcium (Ca) and phosphate (P) ions. However, there has been no study on dentin remineralization by placing samples in an acidic solution without Ca and P ions. Previous studies used saliva-like solutions with neutral pH and Ca and P ions. Therefore, the objective of this study was to investigate a novel method of combining poly(amido amine) (PAMAM) with a composite of nanoparticles of amorphous calcium phosphate (NACP) on dentin remineralization in an acidic solution without Ca and P ions for the first time.

Ageing kinetics and strength of airborne-particle abraded 3Y-TZP ceramics
Tetragonal zirconia polycrystalline ceramic, which is partially stabilized by yttria (3Y-TZP), is highly regarded for its combination of excellent mechanical properties and its enhanced aesthetic appearance compared to metals. It is a popular choice for all-ceramic dental restorations [1]. Its high strength and toughness are achieved through tetragonal-to-monoclinic (t –m) transformation. Under stress, parts of the metastable tetragonal grains transform martensitically to the stable monoclinic variants. (Source: Dental Materials)

PLGA nanoparticles as chlorhexidine-delivery carrier to resin-dentin adhesive interface
Resin-dentin bonding is achieved through dentin demineralization to expose the underlying collagen-fibrils that facilitate resin-permeation into the filigree of mineral-deficit collagen-meshwork forming the transitional resin-dentin hybrid-interface and resin-tags inside dentinal-tubules [1]. Several endogenous dentin-bound matrix metalloproteinases (MMPs) and/or bacterial enzymes were identified to participate in the breakdown of naked collagen-fibrils, drastically affecting the mechanical and structural integrity [2,3].

Bifunctional dentifrice: Amorphous polyphosphate a regeneratively active sealant with potent anti-Streptococcus mutans activity
The development of tooth is an intricate process and the result of a cumulative and reiterative molecular signaling between dental epithelium and dental mesenchyme [1]. While dental mesenchyme differentiates into the pulp and the dentin segment of the complex tooth organ, the epithelial tissues give rise to the enamel layer producing the dental enamel [2]. Both inorganic matrices, enamel and dentin, are composed primarily of calcium and phosphate linked together by physico-chemical interactions [3]. (Source: Dental Materials)

Resin-based core buildup materials are often used for this purpose in clinical dental practice [1 –3].

Measurement uncertainty associated with chromatic confocal profilometry for 3D surface texture characterization of natural human enamel
Optical surface texture measurement and characterization of dental hard tissues are becoming increasingly used within dentistry as a method for detecting and quantifying early enamel damage resulting from common oral pathologies such as dental erosion [1,2]. When quantifying the micro-texture of enamel surface damage, the earliest signs of wear occur at the scale of an enamel prism. Accordingly, recent research into nanometer scale surface changes of polished human enamel using confocal laser microscopy concluded that optimal characterization of acid mediated surface texture changes requires surface metrology instrumentati...

Antimicrobial effect and physicochemical properties of an adhesive system containing nanocapsules
The failure rate of composite resin restorations as a result of recurrent caries was reported between 40 and 70% [1 –3]. The increase of bacterial oral colonization around restorations leads to a pH decrease and consequently recurrent desmineralization process [4]. Post-operative sensitivity is another reason of failure with an occurrence rate around 10% [3]. The sensitivity occurs in deep cavities with a pulpa l involvement that can lead to an acute or chronic inflammation or necrosis of pulp tissue [5,6]. (Source: Dental Materials)

Accelerated fatigue testing of dentin-composite bond with continuously increasing load
Resin composites are now widely used in direct dental restorations. However, as their use becomes more popular, the occurrence of restoration failure has also become more frequent [1,2]. Clinical studies have shown that, on average, composite restorations have a shorter lifetime than amalgam restorations, with one of the main causes of failure being recurrent caries at the tooth-restoration margin [3 –5]. Maintenance of interfacial integrity is therefore essential for a composite restoration to be durable, and all new composite systems should be assessed for their interfacial strength to ensure acceptable clinical pe...
