    The microesthetics of teeth guide the creation of restorations with pleasing appearance that will blend in. Those aspects of single tooth such as morphology, shade, translucency, opalescence and florescence, texture and gloss, as well as tint and stain characterization are important elements. Individualized esthetic fabrication of appealing ceramic restorations can be achieved only if comprehensive and systematic color and related information were obtained clinically and precisely relayed to the dental technician, which includes the determination of the basic tooth color based on a shade guide in accordance with the porcelain system, individualization of the color and translucency of the incisal edge, precise location and recording of the surface and intrinsic color characterization. By combining information of tooth shape, texture and gloss, all the information is transmitted to the technician by means of series of digital photographs. All these techniques comprise the current mainstream in systematic acquisition and communication of individualized esthetic and chromatic information. The purpose of this article was to provide some basic knowledge on those aspects of individualized esthetic and chromatic information for achieving superior clinical results.

    Objective To assess the remineralization property of several toothpastes on initial enamel lesions. Methods Bovine enamel blocks with in vitro produced initial lesion were used. The lesions were subjected to a pH-cycling regime for 12 d, with one of five treatments: NaF(positive control) group, pro-arginine group, casein phosphorylation of protein group, toothpaste with 0.11% fluoride group and with distilled and deionized water (DDW) group for negative control. The samples were subsequently evaluated using a microhardness tester, polarised light microscopy(PLM) and confocal laser scanning microscope(CLSM). Results Surface hardness measurements revealed pro-arginine group, casein phosphorylation of protein group and NaF group had significantly greater effect on enhancing remineralization than that of toothpaste with 0.11% fluoride group(P<0.05). Detailed investigation of PLM indicated that casein phosphorylation of protein group and toothpaste with 0.11% fluoride group had limited capacity to reduce the lesion depth compared with pro-arginine group and NaF group(P<0.05). Comparing with toothpaste with 0.11% fluoride group , casein phosphorylation of protein group had a significantly greater property of limiting the lesion depth(P<0.05). The results of CLSM inferred that the reduction of fluorescent dye infiltration in toothpaste with 0.11% fluoride group and casein phosphorylation of protein group was less than pro-arginine group and NaF group. Conclusion There is a significant synergistic effect of pro-arginine treatment on promoting the remineralization of initial enamel lesion compared with the other groups.

    The endoplasmic reticulum is susceptible to various stresses that provoke the accumulation of unfolded proteins in it, inducing stress response in cells, and altering the growth and function of cells. This is the endoplasmic reticulum stress(ERS). ERS will happen in chondrocytes, the only cells in cartilage, after exposing to glucose deprivation, interleukin-1β, nitric oxide and some drugs. ERS triggers an evolutionarily conserved series of signal transduction events, which constitutes the unfolded protein response(UPR). The three major transducers of the UPR are inositol-requiring(IRE)1, protein kinase R-like endoplasmic reticulum kinase(PERK), and activating transcription factor(ATF)6. They trigger major signal pathways of UPR, which affect the growth, apoptosis of chondrocytes and the inflammation of cartilage. Advances in the research into ERS, PERK, IRE1 and ATF6 signal pathways are reviewed in this article.
