Objectives: The purpose of this study was to evaluate the association between asthma and dental caries by using data from the Korean National Health and Nutrition Examination Survey (KNHANES), from 2013 to 2015. Methods: The study included 11,731 subjects who were ${\geq}19$ years of age and analyzed their demographic-, socioeconomic-, health-, and oral health care-related data. The chi-squared test and logistic regression analysis were conducted using complex sample analyses to examine the relationship between asthma and dental caries. Results: Compared with the control group, the risk for dental caries in the asthma group was 1.207 times higher, regardless of various confounding factors (p<0.001). In the asthma group, the mean DMFT score was significantly higher than that in the control group (p<0.001). After adjusting for confounding factors, the mean number of DMFT in subjects with asthma was 7.67, which was higher than that in subjects without asthma (7.28) (p<0.001). Conclusions: The study results show that asthma may be a risk factor for dental caries. Therefore, in order to prevent dental caries in asthma patients, oral hygiene education is important.

Background: In our study, a silver diamine fluoride (SDF) compound for the treatment of dental caries was synthesized to characterize its remineralization activity upon direct application to deciduous teeth. This study aimed to use microscopic computed tomography (microCT) and nanoindentation to evaluate whether SDF composite application could effectively arrest dental caries in five exfoliated primary molars. Methods: Carious teeth were extracted and visually examined using quantitative photofluorescence devices (Qraycam and QraypenTM). After performing microCT, the SDF composite was applied to the teeth according to the manufacturer's instructions. The researchers exchanged and precipitated the irritant saliva once daily for 1 week. The teeth were sectioned longitudinally through the centers of the mesial and distal surfaces, embedded, polished, and measured using nanoindentation. Thereafter, microCT was repeated. Statistical analyses were performed using GraphPad Prism software. Results: Following SDF composite application, a remineralized layer was observed on microCT images, and the hardness increased when measured using nanoindentation. We found that demineralized enamel presented with an increased number of irregular crystals in the deep carious lesion group compared with those in the shallow carious lesion group, resulting in a rougher surface. Conclusion: The SDF composite may be used for remineralization of early caries and cessation of advanced caries in primary molars.

The aim of this study was to investigate the caries management by risk assessment (CAMBRA) development process and the latest updated caries risk assessment for the domestic settlement of the CAMBRA program and the activation of dental clinics. A system for CAMBRA was published in California Dental Association (CDA) in 2007. To investigate whether CAMBRA can be successfully implemented outside a university setting, a practice-based research network (PBRN) was created in the San Francisco Bay Area. Based on the CAMBRA-PRAN clinical studies, the caries risk assessment (CRA) tool was updated for patients aged 6 through adults in 2019. The CAMBRA system is expected to be widely and actively used in the dental field in Korea to contribute to oral health care.

The detection of carious lesions is a key point to apply appropriate preventive measures or operative treatment of dental caries. A laser fluorescence device DIAGNOdent$^{(R)}$ (KaVo, Biberach, Germany) has also been shown to be of additional clinical value in the detection of initial caries. This report focus on the DIAGNOdent$^{(R)}$ for caries detection. DIAGNOdent$^{(R)}$ irradiate visible red light at a wavelength of 655 nm to elicit near-infrared fluorescence from caries lesion. This device is known as a reproducible method for caries detection, with good sensitivity and specificity especially for caries detection on occlusal and accessible smooth surfaces. DIAGNOdent$^{(R)}$ tended to be more sensitive method of detecting occlusal dentinal caries, however, showed more false-positive diagnoses than the visual inspection. So Clinician should not use the device as a clinician's primary diagnostic method and it is recommended that the device should be used in the decision-making process in relation to the diagnosis of caries as a second opinion in cases of doubt after visual inspection. The trend of modern dentistry would be a preventive approach rather than invasive treatment of the disease. This is possible only with early detection and respective preventive measures, DIAGNOdent$^{(R)}$ can help the changes.

This study was implemented for 84 students of dental hygiene to show the correlation between dental caries experience and improved caries activity test. Dental caries experience for the sample groups was examined and stimulative saliva secreted for 5 minutes was collected into the tube to check saliva secretion rate. Dentocult LB test was executed to observe Lactobacilli colonies after 96 hour cultivation of culture slides moistened with stimulative saliva. Dentocult SM test(screening strip, site strip) was done to measure SM colonies distribution after 48 hour cultivation of culture strips applied with collected saliva and dental plaque respectively, and salivary buffering capacity was checked by means of Dentobuff strip kit. Following conclusions are obtained after examining the relation between Dentocult LB, Dentocult SM, Dentobuff strip test results and DMFT index, salivary secretion rate. 1. Showed no significant difference between Dentocult LB test results and DMFT index, salivary secretion rate. 2. Showed no significant difference between Dentocult SM(screening strip) test results and DMFT index, salivary secretion rate. 3. Showed significant difference between Dentocult SM(site strip) test results and DMFT index(pE0.05), but showed no significant difference between Dentocult SM(site strip) test results and salivary secretion rate. 4. Showed no significant difference between Dentobuff strip test results and DMFT index, but showed a very wide difference between Dentobuff strip test results and salivary secretion rate(pE0.01).

Objectives : The purpose of our study was to examine the relationship of oral health status such as dental caries and the performance of dietary action guides with six items. Methods : Oral examination and self-administrated questionnaire were conducted on 87 disabled students, aged 6-19 who were attending special school in the area of the metropolitan Seoul. Two logistic regression models to estimate odds ratios and 95% confidence intervals were used to investigate the association dental caries experience and the performance of dietary action guides after controlling for potential confounders. Results : The proportion of study subjects with caries were 37.9%, 26.9%(male) and 54.3%(female), respectively(p<0.05). There was significantly difference the subjects with caries and perceived oral health status(p<0.01). Among the dietary action guides items, skipping breakfast and not avoiding waste food were significantly higher in the proportion of subjects' caries(p<0.05, p<0.01, respectively). The avoiding waste food groups had more possibility of having caries significantly(p<0.05), even after controlling gender, and perceived oral health status. Conclusions : These results indicate that oral health promotion policy with dietary action guides should be strengthened for support of disabled student's dental health.

Objectives: The purpose of this study was to assess the effect of mothers education attainment on prevalence of dental caries among their preschool children. Methods: Data were obtained from the third 2006 Korea National Oral Health Survey. A total of 515 preschool children aged 2 to 7 years and their mothers were selected in this study. We used mother's education level as her socioeconomic position and controlled children's tooth brushing frequency, tooth brushing before bed, the frequency of eating snack, and the preventive dental visit. Whether children experienced dental caries or not and the number of decayed or filled or missing tooth surface they had were used as outcome variables. Results: The proportion of children affected with dental caries was 46.21%. The mother's education level affected children's caries significantly (p<0.05) and children whose mother attended less than high school had more possibility of having caries than children whose mother graduated from college or more (p<0.05). This effect was still significant and got larger(p<0.05), even after controlling children's dental health behavior. Conclusion: This study showed that mother's education level affected the prevalence of caries among their preschool children. In addition, this result indicated a need for more definite policy for children's dental health in lower socioeconomic class with general dental education.

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.

The purpose of this study was to obtain the basic data provide continuous and active dental treatment for the mental handicapped children. The authors studied on the dental caries experience, oral hygiene slates and caries activity test in the mental handicapped children of 9-11 years old, who are housed by rehabilitation school in Kwang-ju and in the 30 normal children of 9-11 years old as a control group. Correlation coefficiency was calculated among the caries experience, oral hygiene states and caries activity test for every children. The obtained results are as follows. 1. The mental handicapped children showed remarkably high score compared to normal children in DMFT index(The Index score was $2.43{\pm}1.98$ in the normal children and $5.26{\pm}4.11$ in the mental handicapped.). 2. Correlation coefficiency was reveled very high score between DT index and DMFT index of the normal children(P<0.01), and the mental handicapped was also high score(P<0.01) between ft index and dmft index. 3. The PMA Index of the mental handicapped children was comparatively higher than the normal(The Index score was $4.03{\pm}4.44$ in the normal children and $7.87{\pm}7.33$ in the mental handicapped.). 4. In the correlation coefficiency between the caries experience and modified snyder test, DMFT index of the normal children was revealed some high score(P<0.05). DMFT index of the mental handicapped was showed remarkably high score(P<0.01).
