Abstract

This paper aims to examine the imagination of contemporary Japanese popular texts toward Chinese (or Chinese-ish) culture, focusing on high fantasies. Taking up this imagination for the epic in high fantasies, it reconsiders the notions of history and narrative in this genre related to the image of China, adopting a gender perspective. Epic literature is a typical example that is related to the “grand narrative” and suffers under the spell of Bakhtin’s dictum: “we encounter the epic as a genre that has not only long since completed its development, but one that is already antiquated (Bakhtin 1981: 3).” From the gender point of view, epic literature has been considered to be typically a masculine genre, from Homer’s Iliad to Milton’s Paradise Lost, as Bernard Schweizer states: “Both in subject matter and in form, epic may well be the most exclusively gender coded of all literary genres (Schweizer 2006: 1).” Japan was no exception; the heroic tales and war chronicles such as The Tale of Heike were definitely labeled male literature, while the diary-form was considered feminine. As far as contemporary Japanese literary genres are concerned, however, a desire for the epic still exists, and gender bias seems to affect them as well; a grand saga for boys’ comics and animation (such as Uchū Senkan Yamato (Star Blazers: The Quest for Iscandar) and the Gundam series in the 1970s-80s) and love and friendship for girls (from Candy Candy in the 1970s to Kimi ni Todoke (From Me to You) in the 2000s). On the other hand, it is also intriguing that these genres seem to foster a desire for the epic among girls, especially epics with some Chinese-ish imagination. This paper also clarifies the girls’ yearning for grand history and the characteristics of the works that have been linked with Chinese-ish (and sometimes East Asia-ish) exoticism.

Abstract

In-office bleaching with high concentrations of hydrogen peroxide (H2O2) agents causes undesirable alterations in the enamel. Surface pre-reacted glass-ionomer (S-PRG) filler is a functional material known for its acid-neutralizing and demineralization-inhibition properties. This study evaluates the effect of S-PRG filler incorporation in H2O2-based bleaching on the enamel surface. Bovine enamel surfaces were bleached using a bleaching paste formulated with a liquid (35% H2O2) and a powder containing 5% or 10% S-PRG filler. The surface roughness and the Vickers microhardness of the treated enamel surfaces were evaluated. The enamel surfaces were observed under a scanning electron microscope (SEM) and analyzed using energy dispersive X-ray (EDX) technology. The surfaces were challenged by citric acid and observed by SEM. The specimens bleached with the paste containing the S-PRG filler showed lower enamel surface roughness and higher microhardness values than did those bleached with the plain paste (0% S-PRG filler); meanwhile, there were no significant differences between the 5% or 10% S-PRG filler groups. The S-PRG filler groups showed enamel surface morphologies similar to those of the non-bleached enamel, according to SEM observation, and EDX analysis detected the presence of fluoride and strontium ions. The S-PRG filler groups showed a higher resistance to erosion. The S-PRG filler mitigated the detrimental effects of bleaching agents on the enamel surface and provided resistance to erosion.

Abstract

The effect of a surface pre-reacted glass ionomer (S-PRG)-containing sealant on the demineralization inhibition and remineralization of intact enamel adjacent to the sealant material was investigated. BeautiSealant (BTS, S-PRG sealant, Shofu), Teeth Mate F-12.0 (TMF, fluoride-releasing sealant, Kuraray Noritake Dental), and an experimental silica-filler sealant were investigated. After pH cycling for 10 days, the enamel surface adjacent to the sealant material was observed using confocal laser microscopy and scanning electron microscopy. The polymerized sealant disks were immersed in a demineralized solution (pH: 4.3) to measure pH change. The enamel specimens with polymerized sealant disks were additionally immersed in demineralized solution, followed by energy-dispersive X-ray spectroscopy. The demineralized area of BTS was significantly smaller than that of TMF and SS (p < 0.05). The surfaces adjacent to the sealant of TMF and SS were demineralized, while the surface of BTS was comparatively intact. An increase in pH values were observed in the BTS and TMF groups. Enamel surfaces presented an inhibition of demineralization for BTS and TMF, but not for SS. Fluoride uptake from the polymerized sealant was greater for BTS than for TMF. The S-PRG-containing sealant showed a buffering ability, demineralization inhibition, promotion of remineralization, and it can be advised for clinical applications.
