Smear Layer-Deproteinization: Improving the Adhesion of Self-Etch Adhesive Systems to Caries-Affected Dentin
AbstractPurpose of reviewThis paper reviews a new method of dentin surface modification, smear layer-deproteinization for self-etch adhesive systems, particularly in relation to improving the adhesion to caries-affected dentin.Recent FindingsRemnants of smear debris, which forms hybridized smear layer with self-etch adhesives, can prevent monomer infiltration and interfere with the chemical interaction of adhesive monomers and the underlying dentin. The hybridized smear layer weakens the physical and chemical properties of the resin-dentin hybridized complex both immediately and over time. Smear layer-deproteinization with...

Zirconia Implants: Is There a Future?
AbstractPurpose of ReviewThis review is making an overview of the behavior of the zirconia-toughened ceramic (ZTC) intended for use in the next generation of dental implants replacing zirconia (yttria-stabilized zirconia [Y-TZP]) currently in use.Recent FindingsThe new ZTCs are joining improved strength and toughness to the excellent biological behavior of TZP currently used worldwide for metal-free dental implants.SummaryMost of the Y-TZP dental implants currently in use are one-piece designs. New two-piece designs are now in the market. This design results very demanding because of the mechanical behavior of the ceramic ...

Fiber-Reinforced Composites for Implant Applications
AbstractPurpose of ReviewAlthough metals, ceramics, and particulate filler resin composites have successfully been used as implant biomaterials for decades, devices made out of these materials do not meet all surgical requirements. This review describes the structure and mechanism of function of biostable glass fiber-reinforced composite (FRC) implants, which contain bioactive glass.Recent FindingsFor instance, metal objects may interfere with some medical imaging systems (computer tomography, magnetic resonance imaging) and biomechanical mismatch of implant and bone may cause stress shielding-related bone resorption. Ther...

The Use of Cone Beam Computed Tomography to Assess Periodontal Biotype
AbstractPurpose of ReviewPeriodontal biotype is a concept with great relevance to clinical practice. Although numerous factors contribute to determining biotype, including soft/hard tissue thickness, soft/hard tissue contours, amount of keratinized tissue, and tooth shape, gingival thickness has been mostly utilized. The use of cone beam computed tomography (CBCT) has been recently proposed as a state-of-the-art approach for assessing periodontal biotypes because it provides information relative to both soft and hard tissue dimensions.Recent FindingsWhen used in conjunction with lip retraction or a dual-scan technique, rel...

Recent Trends in Tricalcium Silicates for Vital Pulp Therapy
AbstractPurpose of ReviewTricalcium silicates are considered as materials of choice for vital pulp therapy. Recent development improved their mechanical and bioactive properties and broadened their clinical application fields. Incorporating resins to tricalcium silicates further decreased the setting time and simplified clinical procedures but raised questions about their potential toxicity.Recent FindingsTricalcium silicates represent an added value in vital pulp therapy. This is ascribed to the pulp high regeneration potential, material byproducts production upon hydration and growth factor release from target cells. Add...

Current Concepts in Carious Tissue Removal
AbstractPurpose of ReviewTo summarize current concepts in carious tissue removal.Recent FindingsTraditionally, caries has been seen as an infectious disease and was treated by attempted complete removal of all cariogenic bacteria. The logical traditional aim of carious tissue removal —removing all bacteria from carious lesions—no longer applies. The contemporary aim of carious tissue removal is to maximize restoration longevity, without unnecessarily removing sound or remineralizable dentin. This is based on recent perspectives that dental caries is a biofilm-based and lifes tyle-mediated disorder. In shallow lesions, ...

The Future of Payment for Dental Care
AbstractPurpose of ReviewTo examine the literature on dental reimbursement methods, with emphasis on paying for value (e.g., health care outcomes) rather than procedure. To make recommendations that would facilitate the expansion of access to dental care for those most in need and improve the oral health of the US population.Recent FindingsAlthough the health care system is moving toward paying for performance and outcomes, dentistry lags behind. We review publications that identify obstacles to payment for outcomes in oral health as well as moving away from traditional fee-for-service reimbursement.SummaryPayment for valu...

Fracture Toughness Testing of Dental Restoratives: a Critical Evaluation
AbstractPurpose of ReviewWe intend by this short critical review to highlight important aspects regarding the mechanical testing of fracture toughness. The final aim is to increase the awareness to the test sensitivity, ultimately increasing the quality and reliability of reported testing results.Recent FindingsIn a well-intended attempt to facilitate testing procedures or provide alternatives for testing material interfaces, authors are resorting to adaptation of testing methodologies without proper theoretical and experimental validation. The assumption of validity in such cases endangers the perpetration of testing stra...

Vitamin Status and Mineralized Tissue Development
AbstractPurpose of ReviewThe physiological control of mineralized tissue development is mediated by two processes: mineralization, such as bone formation due to osteoblast activity, and mineralized tissue destruction by osteoclast bone resorption. In this system, nutritional status, including vitamin intake, influences each regulatory processes, although definite responding mechanisms in target cells vary according to each compound.Recent FindingsIn contrast with water-soluble vitamins that constant supply is required, fat-soluble vitamins such as vitamin D and K are stored in the liver and fat tissue for long time. They a...
