This study aimed to evaluate the use of web-based educational slides providing an-ticipatory guidance on infant oral health and early-childhood caries（ECC）to early-child-hood educators. Slides containing basic guidance in the areas of oral hygiene, fluoride use, the acquisition of oral bacteria, the causes and sequelae of ECC, and the importance of dental visits were provided using smartphones. A test based on six key questions was conducted to evaluate the oral health knowledge of the educators（n=123）be-fore and after viewing the slides. A survey was used to receive participants’ feedback after viewing the slides. A significant improvement in knowledge was observed as assessed by the mean proportion of correct responses following a single viewing of the slides（47±17.8%, p<0.001）. More than 85% of the participants answered positively on the survey about the slides. Web-based educational slides on smartphones can be an effective way to improve educators’ awareness of infant oral health and prevention of ECC.

anatomical difference between the brains of both sexes has been reported; specifically, that the cortex is thicker in women than in men（9）. This is considered to be one of the factors affecting the NIRS dataset. Women are also known to be more prone to depression than men（10, 11）. The tendency to become depressed seems to be related to attention, concentration, judgment, and reduced memory, and there may also sex-related differences in human cognitive function. Thus, it was hypothesized that sex differences also appear in Abstract The data on near-infrared spectroscopy（NIRS）corresponding to the left dorsolateral prefrontal cortex can be used as diagnostic criterion for psychological halitosis. Howev-er, it is unclear how sex differences affect them. Thus, this study aimed to investigate the influence of the differences between sexes using NIRS to diagnose psychological halitosis. The study included 42 patients（21 men and 21 women）with presumed psychological halitosis. All patients underwent volatile sulfur compounds（VSC）concentration analysis and psychological testing. They were investigated using NIRS during the performance of the verbal fluency task. Although 16 channels were measured in total, and the channels 13, 14, and 16 that corresponded to the left dorsolateral prefrontal cortex were analyzed. The results demonstrated that no significant differences were observed between VSC and psychological tests. The integral values and initial activation on the NIRS were significantly higher in men; thus, sex differences were observed. In conclu-sion, the present study suggests that sex differences should be considered when using NIRS as a diagnostic tool for patients with psychological halitosis.

It is well known the high prevalence periodontal disease in Down syndrome（DS）. Tumor necrosis factor alpha（TNF-α）augments invasion of Porphyromonas gingivalis（P. gingivalis）in human gingival epithelial cells. We examined the effect of TNF-α on invasion of P. gingivalis to gingival fibroblasts derived from individuals with DS（DGF）and the influence of the cellular response in DGF pretreated with TNF-α prior to inoculation of P. gingivalis. The invasion assay was performed using gingival fibroblasts derived from individuals with non-DS（NGF）and DGF treated with TNF-α prior to inoculation of P. gingivalis. The mRNA expression of interleukin 6（IL-6）and intercellular adhesion molecule 1（ICAM-1）were quantified using real time PCR. Furthermore, the protein expressions of TNF-α receptor（TNFR）I and II, and phosphorylation of p65 nu-clear factor-κB（NF-κB）and phosphorylation of extracellular signal-regulated kinase （ERK）1/2 were also performed in NGF and DGF pretreated with TNF-α prior to inoculation of P. gingivalis by Western blotting. The number of invasive P. gingivalis in TNF-α pretreated DGF was more than that in NGF. IL-6 and ICAM-1 mRNA expressions in DGF pretreated with TNF-α prior to inoculation of P. gingivalis were significantly higher than those in NGF. The relative signal intensity of TNFR I, phospho p-65 NF-κB, and phospho ERK1/2 were significantly higher than those in NGF. It was considered that TNFR I, phospho p65 NF-κB, and phospho ERK1/2 in DGF pretreated with TNF-α may contribute to enhancement of ICMA-1 mRNA expression and the infection of P. gingivalis. The collaboration of these protein and P. gingivalis may be a key factor for development of severe periodontal disease in DS. anaerobic conditions for 7 days. The colonies were count-ed to determine the number of colony - forming units （CFUs）of invasive P. gingivalis in fibroblast cells. Inva sion assays were performed 3 times for each sample.
