    The purpose of this study was to evaluate the mechanism of action and the inhibiting effects of two types of desensitizers against dentin demineralization using pre-demineralized hypersensitivity tooth model in vitro. In this study, we confirmed that a hypersensitivity tooth model from our preliminary experiment could be prepared by immersing dentin discs in an acetic acid-based solution with pH 5.0 for three days. Dentin discs with three days of demineralization were prepared and applied by one of the desensitizers containing calcium fluoro-alumino-silicate glass (Nanoseal, NS) or fluoro-zinc-silicate glass (Caredyne Shield, CS), followed by an additional three days of demineralization. Dentin discs for three days of demineralization (de3) and six days of demineralization (de6) without the desensitizers were also prepared. The dentin discs after the experimental protocol were scanned using swept-source optical coherence tomography (SS-OCT) to image the cross-sectional (2D) view of the samples and evaluate the SS-OCT signal. The signal intensity profiles of SS-OCT from the region of interest of 300, 500, and 700 µm in depth were obtained to calculate the integrated signal intensity and signal attenuation coefficient. The morphological differences and remaining chemical elements of the dentin discs were also analyzed using scanning electron microscopy and energy-dispersive X-ray spectroscopy. SS-OCT images of CS and NS groups showed no obvious differences between the groups. However, SS-OCT signal profiles for both the CS and NS groups showed smaller attenuation coefficients and larger integrated signal intensities than those of the de6 group. Reactional deposits of the desensitizers even after the additional three days of demineralization were observed on the dentin surface in NS group, whereas remnants containing Zn were detected within the dentinal tubules in CS group. Consequently, both CS and NS groups showed inhibition effects against the additional three days of demineralization in this study. Our findings demonstrate that SS-OCT signal analysis can be used to monitor the dentin demineralization and inhibition effects of desensitizers against dentin demineralization in vitro.

    <p> Purpose: Recently, the application of composite resin restorations has expanded. Although chromatic studies of composite resins have progressed, color differences measured by colorimeters and visual color evaluation do not always match. The aim of this study was to establish a method of evaluating the visual color of composite resins by using the visual analog scale (VAS), which evaluates subjective data as a continuous variable, and to examine its validity.</p><p> Method: One structural color composite resin (experimental resin : ECM-001) and three commercial composite resins of shade A3 were used in this study. Class Ⅴ and class Ⅲ cavities were prepared in artificial maxillary central incisors of four shades (A1, A2, A3, and A3.5) and each composite resin was filled and its color matching was evaluated on a black-and-white background using VAS. The correlation between VAS value and visual evaluation was analyzed. The color matching of teeth and composite resin were statistically analyzed using one-way analysis of variance and Tukey's HSD test (p<0.05). Background differences in the same sample were analyzed by the t-test (p<0.05).</p><p> Results: In the Class Ⅴ restoration, ECM-001 showed better color matching than other composite resins. In the Class Ⅲ restoration, ECM-001 showed excellent color matching with a wide range of teeth shades on the white background. The VAS values of the other composite resins were higher on the black background than on the white background. However, the VAS value of ECM-001 on the black background tended to decrease. Because the evaluation of VAS color matching by evaluators showed the same tendency, the VAS value reflects information that can be recognized by visual observation. It is suggested that the evaluation of VAS value correlates with visual evaluation.</p><p> Conclusion: It is suggested that the evaluation of color matching of composite resin restorations using VAS is useful for structural color composite resins, providing a new method of visually evaluating composite resin restorations.</p>

    The aim of this study was to investigate the effect of Er:YAG laser irradiation on human dentin surface using X-ray photoelectron spectroscopy (XPS). 10 human dentin disks were prepared from extracted human molars for XPS analysis. These specimens were divided into two groups of five: a control group and group that were irradiated by an Er:YAG laser beam (1.00 mJ, 1Hz). All specimens were analyzed by XPS over a wide scanning range and narrow scanning ranges. The Ca/P ratio was calculated from the XPS results.
    In the results, the binding energies of Ca, P, and N in the laser-irradiated group were higher than those in the control group. The Ca/P ratio of the Er:YAG laser irradiated group (1.24 +/- 0.05) was significantly lower than that of the control group (1.52 +/- 0.16). This study showed that Er:YAG laser irradiation decreased Ca/P ratio and denatured the collagen of human dentin.

    Dentin regeneration to the lost dentin is the supreme therapy to keep functionality, aesthetics and so forth in operative dentistry. In 2006, we demonstrated the human bone marrow mesenchymal stem cells (hMSCs) differentiated into odontoblast by the stimulation of Emdogain Gel and TNF-&alpha; set. In 2008, we tried to demonstrate odontoblast that differentiated from hMSCs generate dentin under the artificially synthesized appropriate scaffold and molecular signal in vitro. As a result, the differentiated cell tissue tested positive for osteocalcin by fluorescence antibody method and enzyme antibody technique and positive for calcium compounds with the alizarin red S staining. In addition, we detected the dentin-like tissue outside the cell walls by phase contrast microscopy. These results suggested that hMSCs differentiate into odontoblast and generate dentin using Emdogain Gel and TNF-&alpha; set and peptide hydrogel.

    The mineralization accelerating adhesion materials that added EVA+C (RMSB) were produced experimentally, and we studied it about a bond strength and the biocompatibility. As a result, bond strength decreased with increase of the EVA+C addition ratio. But the level of the decrease was inhibited when SBP30 was treated. The RMSB group showed a tendency to growth similar to Control at the early phase, and cell count was higher than an SB (Superbond) at high ratio of EVA+C group. It was a combination of SBP30 and 7P (SB/EVA+C = 40wt%/60wt%) that showed a high bond strength and a good cell proliferation. Also, as a result of animal experiment, 7P had weaker inflammation than an SB and mineralized tissue formation was good. It was suggested that it was obtained high adhesive property and biocompatibility by adding EVA+C in an SB at the appropriate ratio in conclusion.

    The aim of this study was to investigate the effect of bioabsorbable material on the direct pulp capping to know whether this material has a function in dentin regeneration by bioabsorption. Class V cavities with the exposed pulp area were prepared on the buccal surface of first molars in young beagle dogs. All cavities were conditioned with a self-etching primer (Clearfil SE Primer). In the cavities of right side (experimental group), the exposed pulp was covered with a bioabsorbable sheet (Kurabio AG), and then the cavities were coated with an adhesive agent (Clearfil SE Bond) and resorted with a resin composite. The left side cavities (control group) were applied the adhesive agent without the bioabsorbable sheet and restored with a resin composite. On three and six months after surgery, the teeth were extracted, immersion-fixed and decalcified. Afterward, the teeth were frozen-sectioned, stained with hematoxylin and eosin and observed using a light microscopy. In the experimental group, a large amount of the tertiary dentin was formed into the prepared cavity. On the other hand, the tertiary dentin was almost not formed into the cavity in the control group. The significantly tertiary dentin formation was recognized into the prepared cavity when the exposed pulp area had been covered by a bioabsorbable material. This result suggested that the space making by a bioabsorbable material could produce the derivation of pulp tissue and then dentin regeneration into the prepared cavity.

    We analyzed loss of heterozygosity in detail of the long arm of chromosome 4 in 40 oral cancer by using 16 microsatellite markers based on the recent data from human genome sequence and defined the deletional mapping of the region with putative tumor suppressor genes. Our data revealed two distinct commonly deleted regions around the markers D4S2623 and D4S1644 with an allelic deletion of 44% and 39%, respectively. Additional mapping and use of the markers near one of these hot spots narrowed down the minimally deleted region about 1.5Mbp around the marker, D4S2623. Caspase 6 is just localized 280kb distant from the marker, D4S2623. Fine mapping of this region with possible tumor suppressor gene suggest caspase 6 as a putative tumor suppressor gene. Further molecular analysis of caspase 6 should be performed to clarify its role in oral carcinogenesis.

    We recently reported the frequent deletion of chromosome 4q25 region in oral squamous cell carcinoma and discussed the Caspase-6 as a possible tumor suppressor gene in this region due to its near location to this hot spot. We this time examined the role of Caspase-6 in oral cancers. mRNA expression level, protein localization and gene mutation of Caspase-6 were analyzed. Reverse-transcription-PCR analysis demonstrated decreased expression in 40% and equal expression in 30% of Caspase-6 mRNA of primary tumors as compared with that matched normal samples. cDNA sequencing analysis of Caspase-6 did not reveal any somatic mutation. Caspase-6 protein localization was in similar proportion with its mRNA expression. Failure of Caspase-6 response in tumor samples as compared to normal samples could suggest Caspase-6 as a candidate tumor suppressor gene in a subset of oral cancer.

    Basaloid squamous cell carcinoma (BSCC) is a virulent variant of squamous cell carcinoma. We present a case of BSCC affecting the tongue of a 57-year old Japanese male. Microscopically, BSCC was diagnosed on the basis of presence of basaloid carcinomatous component in intimate contact with smaller areas of conventional squamous cell carcinoma. Immunohistochemistry demonstrated positive staining of tumor epithelium for pan-keratin marker MNF116, CK8, CK17, CK19 and CEA, weak immunoreactivity for CK14, EMA and S-100 protein and negative staining for CK1 and alpha-smooth muscle actin. The principal differential diagnoses considered were adenoid cystic carcinoma, adenosquamous carcinoma and polymorphous low-grade adenocarcinoma. © 2005 Elsevier Ltd. All rights reserved.

    In our past study, we confirmed the highest Loss of heterozygosity frequency in 4q25 (D4S2623), and we observed gene Caspase-6 in the proximity to D4S2623, which has a relevant function during apoptosis and therefore can also work like TSG. So we examined Caspase-6 mRNA expression level. Reverse-transcription-PCR analysis demonstrated decreased expression in 40% and equal expression in 30% of Caspase-6 mRNA of primary tumors as compared with the matched normal samples. We also examined Caspase-6 cDNA sequencing for mutations. But no mutation was detected. These findings suggested the possibility of Caspase-6 gene to function as a tumor suppressor gene in a subset of oral SCC.

    Type IV collagen, the major component of basement membrane (BM), demonstrates a stage- and position-specific distribution of its isoforms during tooth development. To determine its localization in BM of malignant odontogenic neoplasms, immunohistochemistry using six anti-alpha(IV) chain-specific monoclonal antibodies was performed. Results disclosed that BM demonstrated an irregular alpha(IV) chain profile in tooth germ as compared to benign odontogenic neoplasms. No alpha3(IV) chains were detected. Expression of alpha1(IV)/alpha2(IV) and alpha4(IV), alpha5(IV)/alpha6(IV) chains was ameloblastic fibro-odontosarcoma, but not the inductive hard tissues. Ameloblastic carcinoma showed specific alpha1 (IV)/alpha2(IV) chain loss, while primary intraosseous carcinoma demonstrated a discontinuous alpha1 (IV)/alpha2(IV) and alpha5(IV)/alpha6(IV) staining pattern. The present results suggest that modification and remodeling of BM collagen IV alpha chains occur during malignant odontogenic neoplasms' progression.

    Tumor suppressor gene (TSG) has a very important role in cancer formation and squamous cell carcinoma (SCC) is the most common malignant tumor in oral region. So the aim of our study is a finding a new TSG in oral sec. Loss of Heterozygosity (LOH) is an effective means to discover TSG. In past studies, LOH has been frequently detected at chromosome 4q22-35 region in human oral SCC. This suggests the existence of tumor suppressor genes. We analysed LOH at 4q22-35 region in 40 oral SCC casrs by using 17 microsatellite markers and found allelic deletions in 85% (34/40) of the significant cases. We detected two high LOH regions, one is around D4S2623 and the other is around D4S1644. D4S2623 showed the higher LOH frequency being 44%. When we redefined the map of 4q22-35 region according to the contiguous sequences, we observed gene Caspase-6 in the proximity of D4S2623, which has a relevant function during apoptosis and therefore can also work like TSG.
