The purpose of this paper is to be studied the Devil's types and the special effect makeup's techniques expressed on horror movies. As the theoretical background, the researcher inquired the origin of Satan, Demon and Devil, and the shapes and meanings portrayed in the religion, philosophy art and literature. Also classified the Devil's types of the movies, and examined the factors, techniques and aesthetic characteristics of special effect makeup for each of them. The results are as follows. 1. The Devil's types are the Werewolf, the Zombie and the Vampire. The Werewolf is a kind of Devil that changes into a wolf when the full moon rises. It requires animatronics, rubber body suits, furs and fangs for special makeup effects. The Zombie is a dead body that the exorcist restored with a narcotic drug, and it nibbles on human's brain and flesh. So it needs decayed or pale skins, scars, bald heads, non-focus eyes and false teeth for making this character. The Vampire is a bloodsucking ghost. Therefore, it uses fangs, evil eyes, rubber body suits and dropping blood for special effect makeup. 2. They expresses Sadism, Masquerade and Cruelty as the aesthetic characteristics of the Devil's special effect makeup.

The purpose of the study was to observe the association between the main colors of school children's drawings of dental treatment situation and their dental anxiety. The subjects of study were 688 school children from 2nd to 4th grade. Caries experience was investigated by oral examination. Questionnaire survey was done regarding children's attitude toward the dentist and dental treatment and their experience of pain and fear during the dental treatment. Colors with high frequency of use were green, blue, yellow, orange, pink, purple, gray, brown, yellow ochre, red, white, and black in order. Boys used green and blue, and girls used yellow and orange, more than each other. As the grade increased, white, yellow, and blue increased and brown decreased. Colors with high dental anxiety level were black, brown, red, white, blue, orange, yellow and green, yellow ochre, gray, pink, and purple in order, and the upper four represented 10.5% of the subjects. Children with high decayed teeth rate had a tendency to use colors of high dental anxiety level. Black color had the most obvious association with the pain and fear of dental treatment.

The restoration of endodontic tooth is always a challenge for the clinician, not only due to excessive loss of tooth structure but also invasion of the biological width due to large decayed lesions. In this paper, the 7 most common clinical scenarios in molars with class II lesions ever deeper were examined. This includes both the type of restoration (direct or indirect) and the management of the cavity margin, such as the need for deep margin elevation (DME) or crown lengthening. It is necessary to have the DME when the healthy tooth remnant is in the sulcus or at the epithelium level. For caries that reaches the connective tissue or the bone crest, crown lengthening is required. Endocrowns are a good treatment option in the endodontically treated tooth when the loss of structure is advanced.

Objective: This study aimed to investigate the factors associated with masticatory performance, as measured with a chewing gum containing spherical resinous microparticles, and to evaluate the method by examining the relationship with self-reported masticatory status. Methods: The participants in this study comprised 903 industrial workers (mean age, $42.2{\pm}11.6years$). A questionnaire was administered to assess self-reported masticatory status. The masticatory performance score was calculated by counting the number of particles in the chewing gum. Clinical oral examinations were administered. Multiple linear regression analysis was conducted on the masticatory performance scores to examine the related factors. Analysis of covariance was conducted to investigate the association between the masticatory performance score and the self-reported masticatory status. Results: Significant predictors of the masticatory performance score were sex (p<0.001), age (p<0.001), decayed teeth (p=0.009), total-functional tooth units (p<0.001), periodontitis (p=0.003), and malocclusion (p=0.011). The relationship between the masticatory performance score and the self-reported masticatory status was attenuated after controlling for confounding factors. Conclusion: The masticatory performance increased with age and decreased as the oral health status worsened. Using this chewing gum method partly, but not comprehensively, reflects masticatory performance. Therefore, various masticatory performance-related indexes should be employed to measure masticatory performance accurately.

Objectives: This study aimed to examine the association between age at menarche and two major oral diseases. Methods: Data from the 7th Korean National Health and Nutrition Examination Survey (2016-2018) were used. The participants included girls and women aged 12 years and above. Thedataofa total of 7,420 participants were analyzed. Statistical analyses were performed using complex samples cross-tabulation analysis and complex samples general linear model. Results: The average age at menarche of those aged 12 to 80 years was 13.81 years. The age at menarche was found to be associated with decayed-missing-filled teeth (DMFT) (p<0.05). When the age at menarche was nine years, DMFT was 4.20 when it was 19 years, DMFT was 10.80. The age at menarche was found to be associated with periodontal tissue state (p<0.05). The group with early menarche age had healthier periodontal tissues (17.1%), whereas the group with late menarche age had more unhealthy periodontal tissues (17.9%) (p<0.001). Conclusions: The age at menarche was associated with two major oral diseases. Therefore, it is necessary to provide women with oral hygiene care and oral health education to prevent major oral diseases before their secondary sex characteristics appear.

Objectives: The aim of this study was to investigate the effect of breastfeeding on the occurrence of early childhood caries in Korean infants and toddlers. Methods: Data on oral examinations of infants and toddlers of the National Health Insurance Service were analyzed. The study subjects were children who participated in both the first, second, and third oral examinations and the first general health examination in 2008-2017 (n=142,185). Based on the responses to the questionnaire, the subjects were classified into breastfeeding, formula feeding, and mixed feeding groups. The participants were monitored for the development of early childhood caries in three sequential oral examinations. Results: Based on the oral examination results conducted at 54-65 months old, the decayed-filled teeth index of the breastfeeding group was the highest (2.03±3.08), followed by the mixed (1.96±3.03) and the formula feeding groups (1.82±2.91). The Cox proportional hazard regression model including all the variables showed that the risk of developing dental caries was significantly lower in the formula (hazard ratio [HR], 0.85) and mixed feeding groups (HR, 0.91) than in the breastfeeding group. Conclusions: Breastfeeding children have a higher risk of early childhood caries; therefore, oral hygiene education and regular dental check-ups are necessary.

Background: This study aimed to analyze trends in oral health research among people with disabilities. Methods: Data were obtained from 70 oral studies on individuals with disabilities from 2000 to 2024. Keywords were analyzed. Frequency, betweenness centrality, and cluster analyses were performed using NetMiner. Results: The main keywords for oral health research on disabled people were oral health, dental caries, DMFT (decayed-missing-filled-teeth), dental treatment, oral health centers, and disabled children. As a result of the centrality analysis, DMFT had the highest connectivity, followed by disabled children, special care dentistry, oral health behavior, periodontitis, and health insurance. Cluster analysis results of research on disabled people: Group 1, oral diseases and functions of disabled people; Group 2, oral care for disabled children; Group 3, dental treatment for disabled people; Group 4, oral health policy; Group 5, oral care by dental hygienists; and Group 6, conservative dentistry. Conclusion: Considering the increase in the number of disabled people in a super-aging society, research on ways to promote oral health for disabled people, oral health policies, and training of oral health experts for disabled people is required.

The aim of this study was to examine the effectiveness of oral health promotion program in a group of 9~18-year-old children and adolescents living in four orphanages in Dong-gu, Daejeon. The program was based on oral disease prevention program including oral health education, fluoride application and scaling every six months. Oral health status of total 109 orphans was examined by one dentists who were trained in 2010 Korean National Oral Health Survey. Dental caries index, community periodontal index and modified patient hygiene performance index (M-PHP) were checked using dental unit chair. Child oral health impact profile (COHIP) and subjective oral health recognition survey were carried out. Compared with data of 2010 national sample, the mean of decayed, missing and filled teeth showed no difference between the subjects and test values, but the means of decayed teeth, decayed surface, toothbrushing frequency of the subjects showed to become worse with advancing years in spite of oral health promotion program. COHIP, subjective oral health status showed lower than test values, too. In M-PHP and Calculus index, the subjects showed better by periodic oral health education and scaling. We suggest that oral health promotion program for orphans include oral disease treatment program as well as preventive program to improve oral health of orphans efficiently. And, oral health promotion program has to be connected with psychological support for improving quality of life of orphans.

The aim of this study was to evaluate whether the number of existing permanent teeth is associated with chronic obstructive pulmonary disease (COPD) in a representative sample of Korean adults. Data from 3,107 subjects who participated in the 2009 Korea National Health and Nutrition Examination Survey were examined. The dependent variable was COPD and the independent variable was the number of existing permanent teeth. Spirometry results were classified into three groups (normal pattern, restrictive pattern, and obstructive pattern) by trained technicians. We used dichotomized COPD variables (no vs. yes). The number of existing permanent teeth was evaluated by oral examination and divided into 3 groups (0~19, 20~27, and 28). Demographic factors (age group and sex group), socioeconomic status (education and income), health behaviors (smoking and drinking), oral health and behavior (frequency of toothbrushing; periodontitis; decayed, missing, filled, permanent teeth index; and denture status), and general health status (body mass index, diabetes mellitus, and hypertension) were included as confounders in the analysis. Bivariate analysis and multivariate logistic regression analyses including confounders were applied, and all analyses considered a complex sampling design. Stratified analysis was performed by smoking status. After controlling for various confounders, there was a significant association between the number of existing permanent teeth and COPD (odds ratio [OR], 1.90; 95% confidence interval [CI], 1.20~3.00 for the 20~27 group; OR, 3.93; 95% CI, 1.75~8.84 for the 0~19 group). The association was more significant in current smokers (OR, 8.90; 95% CI, 2.53~31.33). Our data indicate that the number of existing permanent teeth was independently associated with COPD, especially in current smokers. Further longitudinal research is needed to determine whether oral health promotion plays a role in the improvement of lung function and prevention of COPD.

The oral health status and practices related to oral health among 44-54-year-, 55-64-year- and 65-year-old needy residents were assessed. The subjects were the residents at the Unbong Permanent Rental Apartment, Bansong-dong, Haeundae-gu. Pusan, Korea. An oral epidemiological survey was undertaken to determine the status of dental caries and periodontal health. Periodontal health were analyzed by the tool of CPITN (Community Periodontal Index of Treatment Needs). A questionnaire was used to interview for the practices of toothbrushing. The numbers of subjects were 192 for the interview on toothbrushing, 228 for the survey of dental status and 208 for the survey of periodontal status. The major results were as follows: 1. Toothbrushing frequencies per day were 1.9 among 44-54-year-, 1.7 among 55-64-year- and 1.7 among 65+-year-subjects. Percentages of after-meal-toothbrushings among total brushing frequencies per day were 73.7% among 44-54-year-, 70.6% among 55-64-year- and 76.5% among 65+-year-subjects. 2. DMFT indices were 15.5 among 44-54-year-, 16.4 among 55-64-year- and 26.6 among 65-year-subjects. Decayed teeth component of DMF teeth were 23.9% among 44-54-year-, 11.6% among 55-64-year- and 62.8% among 65+-year-subjects. Missed teeth component of DMF teeth were 55.59% among 44-54-year-, 62.8% among 55-64-year- and 77.4% among 65+-year-subjects. Filled teeth component of DMF teeth were 20.0% among 44-54-year-, 25.0% among 55-64-year- and 10.9% among 65+-year-subjects. 3. Sound permanent teeth were 16.4 among 44-54-year-, 15.6 among 55-64-year- and 5.4 among 65+-year-subjects. Present permanent teeth were 23.7 among 44-54-year-, 21.6 among 55-64-year- and 10.9 among 65-year-subjects. 4. Subjects who needed professional oral prophylaxis were 75.0% among 44-54-year-, 83.3% among 55-64-year-and 76.9% among 65-year-subjects. Subjects who needed complex periodontal treatments were 16.7% among 44-54-year-, 13.3% among 55-64-year- and 15.4% among 65+-year-subjects. 5. Sextants which needed professional oral prophylaxis were 59.3% among 44-54-year-, 71.5% among 55-64-year- and 71.5% among 65+-year-subjects. Sextants which needed complex periodontal treatments were 5.6% among 44-54-year-, 4.1% among 55-64-year- and 5.7% among 65+-year-subjects. 6. Systematic comprehensive oral health care services should be developed for old needy residents in urban area.
