Objectives: The purpose of the present study was to evaluate the whitening effect, morphological and structural changes, and remineralization of the enamel induced by 3 combined agents: amorphous calcium phosphate (ACP), hydroxyapatite (HA), and tetrasodium pyrophosphate (TSP). Methods: The study was performed on 90 bovine enamel slabs, which were divided into the 6 groups: negative control-distilled water (Group 1); positive control-opalescence F (Group 2); 10% mixed agent (Group 3); 25% mixed agent (Group 4); 50% mixed agent (Group 5); and 100% mixed agent (Group 6). Changes in the shade of the enamel slabs were evaluated using Shade Eye-NCC. Morphological changes were assessed by scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM) was used to determine the remineralizing effect of the three agents on enamel slabs. Results: The change in shade of the enamel (ad*) was noted to increase significantly with increase in whitening frequency in all groups. The value of Δn* was significantly greater in all groups except for the negative control group (P<0.001). SEM revealed that the control group, Group 5, and Group 6 had similar morphologies. The fluorescence lesion areas in the 4 mixture-treated group were significantly smaller than those in the positive control group (P<0.001). Conclusions: These results showed that the mixture of ACP, HA, and TSP was highly effective for bovine enamel whitening and acted by inducing the remineralization of enamel. Clinical significance: We evaluated the applicability of a new mixture containing ACP, HA, and TSP. This mixture would be highly useful in aesthetic dentistry because of its whitening efficiency, which does not compromise the enamel`s integrity.

이 연구는 일부 아동들을 대상으로 일상생활구강영향지수와 구강건강관련행태, 구강건강상태를 조사하였으며, 일상생활구강영향지수에 영향을 미치는 요인을 파악하고, 서로간의 연관성을 알아보고자 2012년 3월부터 5월까지 인천광역시와 천안시 소재 일부 학교 아동 200명을 대상으로 설문조사를 하였다. 그 중 설문조사가 완료된 175명을 최종 분석대상으로 하여 SPSS WIN 20.0 프로그램을 이용하여 분석한 후 다음과 같은 결과를 얻었다. 일반적 특성과 C-OIDP 불편경험 항목 수, 구강건강관련행태와 C-OIDP 불편경험 항목 수는 통계적으로 유의한 차이가 없었다(p>0.05). 그리고 C-OIDP 불편 경험 항목 수가 많을수록 충전유치치면과(p=0.024), 우식경험유치치면이 많고(p=0.049), 구강 내 전체충전치면과(p=0.021) 구강내 전체우식경험치면 역시 많은 것으로 나타났다(p=0.047).이것은 객관적인 구강건강상태와 주관적 지표인 C-OIDP가서로 관련성이 있음을 보여준다. C-OIDP 여덟 항목 중 영향빈도가 높은 것은 식사하기, 치아 닦기, 웃기 순이었으며, 구강 내 전체 우식경험치면수가 많고, 지난 한 달간 잇몸 통증을 경험한 대상자에서 C-OIDP 항목점수가 높았다. 이것은 C-OIDP가 우식과 치주 상태와 관련이 있음을 보여주는 것이다. 이 연구는 주관적 구강건강지표와 실제 구강건강과의 관련성을 본 연구로서 매우 의미 있는 연구이며, 앞으로 C-OIDP에 영향을 미치는 다양한 요인에 대한 연구가 필요할 것으로 생각된다. The purposes of this study were to investigate the factors affection the Oral Impacts on Daily Performances for Children (C-OIDP) in elementary and middle school students, and identify the association between oral health-related behaviors, oral health condition and C-OIDP. A cross-sectional study was conducted in three schools in Incheon, Asan, Korea. A total of 175 selected children were interviewed by a trained examiner using a questionnaire. Oral Health Related Quality of Life was assessed by the Korean version of C-OIDP. Socio-economic characteristics, oral health-related behaviors, oral health condition and C-OIDP were verified using the questionnaire. ANOVA analysis was performed to determine the oral health and C-OIDP, and multiple regression analysis was performed to determine the factors affecting the C-OIDP. The activities with the greatest effect were eating (28.0%), cleaning teeth (22.9%), and smiling (18.9%). In the logistic regression model, the high item score of C-OIDP was associated with experiencing dental caries and gum pain in the past month. The more the C-OIDP prevalence item, the more the fillng deciduous tooth surface (fs) (p=0.024), caries experienced deciduous tooth surface (dfs) (p=0.049), total caries tooth surface (ds+DS) (p=0.021), and total caries experienced tooth surface (dfs+DMFS) (p=0.047). It can be concluded that the factors affecting C-OIDP are fs, dfs, dfs+DMFS, and gingival pain. Based on these results, we can improve C-OIDP to advance preventive practice.

Objectives. Streptococcus mutans ( S. mutans) is the major causative bacteria in human dental decay. Most children acquire these bacteria from their mothers by saliva contacts during the emergence of the primary teeth at the age of 2.5 years. Children whose teeth are colonized earlier by S. mutans show higher caries experience than those colonized later or not at all. Thus, the purpose of this study was to assess the effect of maternal use gums containing xylitol on the characteristics of S. mutans in children`s oral cavities. Methods. The mothers voluntarily participating in women`s oral health prevention program were divided into two groups (a control and a xylitol group). The xylitol chewing gum group had consumed 2 gum pellets, 3 times a day for 24 months, and then they were followed for 30 months. For children`s S. mutans analyses, dental plaque was collected at 6, 24 and 30 months after birth. Dental plaque samples were incubated in MSB plate and the prevalence of S. mutans was assessed. After isolation and identification, transmission electron microscopy and real-time RT-PCR were performed to analyze the characteristics of S. mutans. Results. The S. mutans prevalence increased in both of the groups over the study period, but the polysaccharides synthesis was decreased in the xylitol group. The expression of gtfB, gtfD and ftf were significantly reduced in the xylitol group (p<0.05). Conclusions. These findings indicate that chewing xylitol gum over a long period of the mother can prevent dental caries in their children by decreasing the gene expression associated virulence and the extracellular polysaccharides synthesis of S. mutans.

Objectives: Streptococcus mutans (S. mutans) is the major causative bacteria in dental caries. Xylitol is an effective anticarious natural sugar substitute by inhibiting the virulence of S. mutans. However, longterm xylitol consumption leads to the emergence of the xylitol-resistant S. mutans (XR). The aim of this study is to analyze the difference of gene expression profile of xylitol-sensitive S. mutans (XS) and XR in 0.5% glucose containing TYE media, using a DNA chip. Methods: S. mutans KCTC3065 was maintained in 0.5% glucose and 1% xylitol containing TYE media, during 30 days at 37oC 10% CO2 to form XR. The same procedures without xylitol were repeated for the formation of XS. Both XS and XR were cultured in 0.5% glucose with or without 1% xylitol containing TYE media overnight and total RNA was extracted. RNA from XS was labeled with Cy-3 dye as control, and XR were labeled with Cy-5 as references. DNA chip was hybridized for 18-20 h at 42oC. Results: A total of 277 genes of DNA chip data were significantly increased or decreased in XR. There is a total of 174 XR up-regulated genes in 0.5% glucose and 1% xylitol containing TYE media, and a total of 103 down-regulated genes. For compare with results of DNA chip, 11 in up-regulated genes and 10 in down-regulated were verified by RT-PCR. The most abundant increased genes in XR were related to cell envelope, cellular processes, DNA metabolism, transcription, and protein folding and stabilization. The decreased genes in XR were related to amino acid biosynthesis, toxin production and resistance, energy metabolism, ribosomal proteins synthesis, and signal transduction. Conclusions: These results indicate that the difference of gene expression profile of XS and XR may be in existence. In particular, results of this study for XR up-regulated genes have a lot of similarities with the already published xylitol-related researches and other functional studies.
