Fatigue failure load and finite element analysis of multilayer ceramic restorations
Ceramic materials have been widely used in restorative treatments due to excellent qualities as such superior aesthetics, biocompatibility, chemical stability, wear resistance, low biofilm adhesion and color stability [1]. In addition, the constant optimization of its microstructure and physical properties has allowed its use in areas of great masticatory effort such as posterior regions [2]. Regardless of the type of ceramic material used, clinical researches point to an estimated survival rate of around 90% after 5years [3 –7]. (Source: Dental Materials)

Calcium phosphate coatings elaborated by the soaking process on titanium dental implants: Surface preparation, processing and physical –chemical characterization
Dental implants provide a good solution for the replacement of tooth roots. Indeed, dental implants restore the functional symmetry of dentition and thus help to maintain the jawbone density and shape, eating and talking ability and smiling aesthetic. All these functions support the psychological, social and physical well-being of the patient. Nevertheless, a long time for bone healing (3 –6 months) is required between the implantation and the positioning of the crown (artificial tooth) on the dental implant, which fully reestablish the function of the tooth.

Assessing the osteogenic potential of zirconia and titanium surfaces with an advanced in vitro model
Dental implants are the gold standard of dental replacement strategies and to date, a multitude of implant materials and surface modifications have been developed and are routinely applied in clinics. Especially titanium and titanium alloys have been the materials of choice for dental implant systems due to their exceptional mechanical and chemical properties as well as the biological response to those implants [1]. Various in vitro and in vivo studies successfully showed that the implant surface properties including topography, chemical composition, and hydrophilicity regulate the cellular fate decisions of osteoprogenito...

Effect of cryopreservation of teeth on the structural integrity of dentin
The autotransplantation of teeth after cryopreservation has become an increasingly viable method for whole tooth replacement. While the immediate success rates are quite high, damage introduced by cryopreservation within the dentin or enamel could be detrimental to the durability of these teeth. (Source: Dental Materials)

Synthesis of core-shell structured ZnO@m-SiO2 with excellent reinforcing effect and antimicrobial activity for dental resin composites
Dental caries is one of the most common oral health diseases nowadays, and the improper treatment can result in secondary infections and systemic diseases, such as arthritis, heart disease and chronic nephritis [1]. Therefore, the versatile and reliable restorative materials for caries treatment are highly required. Due to the superior aesthetics and biocompatibility over amalgam alloys, dental resin composites have been widely used to restore dental caries and other defects since 1960s [2,3]. These composites are made from surface-modified inorganic fillers dispersed in a photopolymerizable resin matrix, which can form a ...

Cytotoxic and genotoxic potential of the type I photoinitiators BAPO and TPO on human oral keratinocytes and V79 fibroblasts
The initiator is an important component of light-curing dental adhesives and resin composites. Camphorquinone (CQ) is the mostly used photoinitiator for photo-polymerizable dental resinous materials. CQ requires an accelerator, such as a tertiary amine, to promote an efficient polymerization process [1]. However, despite its clinical acceptance and broad application, the CQ/amine system has its limitations. It can impair the esthetic appearance of resin restorations due to its yellow colour. It also may cause adverse interactions with acidic monomers, which may decrease the stability of the dental materials and affect the ...

Quaternary ammonium silane-based antibacterial and anti-proteolytic cavity cleanser
Although considerable advancements have been achieved in dentin bonding over the past decade, the durability of tooth-colored plastic fillings remains a clinically formidable issue that has not been satisfactorily addressed. There are two major challenges in achieving durable resin –dentin bonds. Secondary caries has been thought to be one of the primary challenges [1]. The minimal intervention approach is currently recommended for the treatment of deep carious lesions, to preserve tooth structure and avoid damage to the dental pulp complex [2,3].

In situ photochemical crosslinking of hydrogel membrane for Guided Tissue Regeneration
Oral diseases, including dental caries and periodontitis, are among the most important global health burdens, affecting the majority of school-aged children and adults worldwide. The prevalence of periodontitis is reported to be between 20 and 50% of the worldwide population [1], with reported relationships between periodontitis and systemic diseases such as cardiovascular disease [2,3]. In Europe, the more severe forms of periodontitis affect 10% of the population [4]. (Source: Dental Materials)
