Gene, netwoks, occlusal clock and functional patches : new understanding of pattern and process in the evolution of dentition
" Our understanding of the evolution of the dentition has been transformed by advances in the developmental biology, genetics, and functional morphology of teeth, as well as the methods available for studying tooth form and function. The hierarchical complexity of dental developmental genetics combined with dynamic effects of cells and tissues during development allow for substantial, rapid, and potentially non-linear evolutionary changes. Studies of selection on tooth function in the wild and evolutionary functional comparisons both ... "

Platelet-rich plasma and its derivates as promising bioactive materials for regenerative medicine : basic principles and concepts underlying recent advances
" Over the past decade, platelet-rich plasma (PRP), a platelet-concentrated plasma fraction, has been widely investigated and applied to regenerative medicine. The clinical utility of PRP is supported by evidence that PRP contains high concentrations of platelet-related growth factors and normal concentrations of plasma-derived fibrinogen, both of which contribute synergistically to the regenerative process. Additionally, its superior cost-efficacy versus conventional therapies is attractive to many clinicians. However, current disadvantages of PRP include a relatively complicated preparation ... "

Expression of trasncripts for fibroblast growth factor 18 and its possible receptors during postnatal dentin formation in rat molars
" Fibroblast growth factors (FGFs) regulate the proliferation and differentiation of various cells via their respective receptors (FGFRs). During the early stages of tooth development in fetal mice, FGFs and FGFRs have been shown to be expressed in dental epithelia and mesenchymal cells at the initial stages of odontogenesis and to regulate cell proliferation and differentiation. However, little is known about the expression patterns of FGFs in the advanced stages of tooth development. In the present ... "

Cyclophoshamide inhibits root development of milar teeth in growing mice
" Root development of permanent teeth is disturbed in survivors of childhood cancer. Cyclophosphamide (CY) is a cytostatic drug commonly used for chemotherapy in children with cancer. This study aimed to evaluate the effects of CY on the development of molar teeth until the completion of occlusion in young mice, focusing on Hertwig’s epithelial root sheath (HERS). We treated thirty-two 12-day-old ICR mice with CY (100 mg/kg; 100-CY group), and 36 control mice with saline. At ... "

Periostin in a negative regulator iof mineralization in the denta pulp tissue
" The dental pulp tissue is encased in hard tissue and surrounded by hard tissue-forming cells, but remains in a non-mineralized state itself, suggesting the presence of regulatory mechanisms precluding pulp mineralization. This study aimed to reveal the regulatory function of periostin (Postn), which is essential for osteoblast differ- entiation, for odontoblast differentiation/mineralization. We evaluated the effects of Postn overexpression and RNAi-mediated suppression in mouse dental papilla cells (MDPs) on the expression of odontoblastic markers and ... "

Influence of the base and diluent monomer on network characteristics and mechanical properties of neat resin and composite materials
" This study evaluated the effect of the combi- nation of two dimethacrylate-based monomers [bisphenol A diglycidyl dimethacrylate (BisGMA) or bisphenol A ethoxylated dimethacrylate (BisEMA)] with diluents either derived from ethylene glycol dimethacrylate (ethylene glycol dimethacrylate, diethylene glycol dimethacrylate, triethylene glycol dimethacrylate, tetraethylene glycol di- methacrylate) or 1,10-decanediol dimethacrylate (D3MA) on network characteristics and mechanical properties of neat resin and composite materials. The degree of con- version, maximum rate of polymerization and water sorp- tion/solubility of ... "

Fatty acid effect on sucrose-induced enamel demineralization and cariogenicity of an experimental biofil-caries model
" Based on scarce evidence, fatty acids have been described as anticariogenic. The aim was to evaluate the effect of different types of fatty acids on enamel demin- eralization and on the cariogenic properties of Strepto- coccus mutans biofilms on a biofilm/caries model. Mature biofilms of S. mutans UA159 growing on bovine enamel slabs were exposed to 10 % sucrose for 5 min, 3 times per day followed by exposure to a panel of free fatty ... "

Non-invasive in vivo visualization of enamel defects by reflectance confocal microscopy (RCM)
" The enamel defects (EDs) may present with a variety of clinical manifestations with increasing severity from the sole appearance of pale discoloration to remarkable structural alterations. EDs are responsible for higher caries receptivity. In vivo reflectance confocal microscopy (RCM) allows to image in vivo at microscopic resolution of the dental surface, thus avoiding the tooth extraction and the sample preparation because of its ability to optically scan living tissues along their depth. Aim of this ... "
