Saliva is obviously potential medium to protect the dental caries by not only physical clearing effect, but aggregating action of protein with bacteria. Nevertheless, we still do not understand how the dental caries occur and what brings the individual difference in caries prevalence. In the regards of dental caries prevalence, we hypothesized that the composition of salivary protein might be different from caries susceptible group to caries resistant group. The purposes of this experiment were focused on the molecular analysis of salivary proteins from the subjects who were involved in multiple caries. Electrophoretic analysis was done on the whole saliva collected from the children with and without multiple caries. We found 86.2% of subjects with multiple caries has approximately 120 KDa protein band while 30.4% in the healthy subjects. And the concentration of the total protein on the subjects with multiple caries is significantly higher than that of the healthy group. However, it turned out that the difference of the salivary composition does not affect the bacterial adhesion to hydroxyapatite bead. With regards of enzymes in saliva, the activity of ${\alpha}-amylase$ and lactate dehydrogenase does not have any significant difference between both groups. However, the concentrations of $Na^+\;and\;Cl^-$ in saliva from multiple caries group is higher than that of the control group. Taken all together, it may be concluded that 120 KDa protein in saliva may be associated with the process of dental caries, also the high concentration of protein and $Na^+,\;Cl^-$ in saliva may be linked to dental caries development as a cofactors.

Objectives : This study aimed to explore the influence of food intake and oral health behaviors on dental caries in juveniles. Methods : A total of 2,129 juveniles completed a questionnaire survey to identify the presence of permanent teeth caries, behaviors relevant to oral health and food intake based on the fourth National Health and Nutrition Survey. Results : Multiple logistic regression analysis showed that higher occasions of intake of carbonated drinks significantly cased dental caries in the meanwhile oral health behavior and the number of toothbrushing was in reverse proportion to dntal caries. The risk of dental caries was higher in the group of lower frequency of toothbrushing and intake of carbonated drink. Conclusions : Carbonated drinks intake and the number of toothbrushing is closely related to dental caries. So it is very important to develop oral health education program in order to improve eating habits and toothbrushing habits in juveniles.

Objectives: This study aimed to evaluate the relationship between pit and fissure sealants of the molars, and caries prevalence and experience to assess the effect of sealants on caries prevention. Methods: Data from 16,119 people were extracted from the seventh Korean national health and nutrition examination survey, which was conducted from 2016 to 2018. Demographic, socioeconomic, oral health-related behavioral, and oral examination survey data were collected as independent variables. SAS statistics for complex samples and multiple logistic regression analysis (Windows ver. 9.4) was used for the statistical analyses. Results: Caries prevalence and experience were significantly associated with age, sex, daily toothbrushing frequency, interdental cleaning, and having molar sealant. Multiple logistic regression analysis revealed a significant association between having molar sealants and the caries prevalence and experience among participants under 30 years of age after adjusting socio-economic variables and toothbrushing-related factors. Conclusions: This study confirmed the effect of molar sealants on caries prevention in Korea. Our results support that the application of molar sealants in children, adolescents, and young individuals is effective in preventing caries.

The effectiveness of dental implants in patients with disability, who are non-compliant during treatment, is controversial because of their poor oral health. Thus, oral health-care and management in such patients is concerning. Moreover, limited information is available on prognosis after implant placement. Herein, we describe a patient with schizophrenia who underwent dental implantation under multiple inductions of general anesthesia (5 times) and required conservative treatment and tooth extraction for multiple dental caries and retained roots because of inadequate oral health-care. Postoperatively, fracture of the prosthodontics and progression of dental caries were observed, and with 3 additional inductions of general anesthesia, conservative treatment, implant surgery, and prosthesis implantation were conducted. Postoperative 12-month follow-up since the last prosthesis implantation showed successful results. For patients with schizophrenia, multiple implantation can reduce horizontal bone loss and achieve aesthetic results compared to treatment with removable prosthodontics and could serve as an alternative treatment modality.

The purpose of this study was to examine the influence of maternal socioeconomic status, maternal oral health behaviors, and oral health behaviors of children, on the prevalence of early childhood caries in children aged 5 years. The Korean National Health and Nutrition Examination Survey data collected between 2007 and 2014 were applied to this study, and the study sample included 824 children who received oral examinations and participated in the health behavior survey. The factor that affected the prevalence of early childhood caries were confirmed by maternal and child factors. The data were analyzed using multiple linear regression. The mothers' age, income level, and job status affected the prevalence of early childhood caries. There was a significant difference in the analysis considering the factors of motherhood and children in the prevalence of early childhood caries according to mother's age, education level, income level, and the child's oral examination. The prevalence of early childhood caries was higher in children who received oral examinations than in those who did not. When the mother's educational level was higher than college education, it was found that the index of child, i.e., there was a difference in the prevalence of early childhood caries according to the mother's educational and income levels. These results indicate that maternal socioeconomic characteristics are correlated with the oral health of children. Therefore, oral health education programs that include mothers for the prevention of early dental caries in children may improve the dental health of children. In addition, specific oral health policies are necessary to address the differences in the oral health between the income groups.

Objectives: This study was conducted to assess dental health states of disabled people and analyze association between perception and awareness toward dental health and dental health status. Methods: The survey was performed from June 25 through October 30, 2004. A total of 548 disabled people participated in the study with details of 419 living in eight residential care centers located in Gyeongsangbuk-do and 129 children from a special school and two day-care centers. All subjects underwent oral examination and surveyed through a questionnaire. Parents of 129 children with disabilities were also surveyed through a separate questionnaire. Results: The dental caries experience rate was 82.1% of total 548 subjects. By age, those in their 20s experienced a high rate of dental caries with 87.5%. By educational level, those with a middle school education experienced a high dental caries rate with 91.8% (p<0.05). Of total subjects who experienced dental caries, 78.9% had experience in dental caries treatment. By age, those in their 10s showed a high rate of dental caries treatment with 87.4%(p<0.05). By educational level, those with a high school education showed a high rate of dental caries treatment with 87.7%(p<0.05). Those in residential care centers had a high rate of dental caries treatment with 82.1%, which is significantly higher than 68.8% of those who used day-care centers. A tooth extraction rate was 38.0% of total subjects. Those in their 40s had a higher rate of tooth extraction(p<0.01). Those in residental care centers had a significantly higher rate of extraction with 43.4%, compared with 20.2% of those in day-care centers. Of total subjects, 61.5% had plaque. A high rate of plaque formation was observed in those in their 40s(92.0%), those with a high school education(84.0%) and those with multiple disabilities(77.8%)(p<0.01). Among total subjects, 47.6% maintained healthy periodontal tissue. Those in their 40s and those with multiple disabilities had diseased periodontal tissue(p<0.01). Of 129 disabled children, 43.8% had plaque with parents who were not oral health-conscious while 18.6% had plaque with parents who were oral health-conscious, showing a significant difference(p<0.05) Conclusion: The results of the study suggest the need for educating parents with disabled children about oral health and strengthening programs for oral health for teachers working at special schools and day-care centers.

Objectives: This study investigated the relationship between obesity and dental caries of Korean adolescents. Methods: Data from the Korea National Health and Nutrition Examination Survey (KNHNES VI) (2013 to 2015) were used and targeted adolescents aged 13 to 18 years. For statistical analysis, the SPSS 18.0 program was used, and the significance level was set at 0.05. Results: For the general and health-related characteristics, female students (p=0.001) showed higher decayed, missing, and filled teeth (DMFT) index than male students. Furthermore, DMFT showed higher tendency, as age was higher (p<0.001). Smoking (p=0.011) and drinking experience (p=0.027) revealed higher DMFT. The dental caries experience was significantly different among students who were female (p=0.033), older (p=0.001), and overweight or underweight (p=0.022). In the BMI for the general and health-related characteristics, male students had higher obesity rate than female students (p=0.003), and obese subjects had higher dental checkup in the last year (p=0.013). In multiple linear regression analysis of obesity and DMFT, the unadjusted model showed that the obesity group's DMFT was about 0.8 higher than that of the normal group (p=0.024). However, statistical significance was not shown in the adjusted models. In the logistic regression analysis of obesity and dental caries experience, the unadjusted model 1 (1.93 times), the adjusted model 2 (1.79 times), and model 3 (1.76 times) showed significantly higher dental caries experience. Conclusions: Both obesity and dental caries are related to diet habits and lifestyles and have a negative impact on adult health. Therefore, it is necessary to create a healthy social environment around the adolescent, and proper intervention through education is required to form healthy habits.
