Treacher Collins syndrome(TCS) is an autosomal craniofacial development disorder which results from mutations in the gene TCOF1. Major features include midface hypoplasia, micrognathia, microtia, conductive hearing loss. Oral manifestations are characterized by cleft palate, shortened soft palate, malocclusion, anterior open bite and enamel hypoplasia. The purpose of this presentation is to describe the interesting aspects of dental treatment of a patient with TCS. A 6-year-old boy with TCS visited Seoul National University Dental Hospital for dental caries. Multiple caries was observed from clinical and radiographic examination. Because of multiple caries and behavior management ploblem, dental treatment under general anesthesia was planned. Treatment of posterior teeth was performed and some primary teeth were extracted. General anesthesia was induced and maintained with sevoflurane, nitrous oxide and oxygen. Under general anesthesia, successful dental procedure was done. Considering behavior management problem and medical condition of patient with TCS, general anesthesia can be useful.

Objectives: The purpose of this study is to examine correlation between subjective oral health status and oral-related appearance satisfaction of college students. 100 college students at a college located in Gyeonggi-do participated in the survey, oral examinations, and self-rated oral hygiene management ability tests. The data was then analyzed accordingly. Methods: Frequency test and chi-square statistical analysis were conducted on general characteristics and subjective oral health status, and SAS version 9.2 was used. Results: As a result of this study, students' subjective perceptions about oral health had positive correlation with oral-related appearance(p <0.05). It is noteworthy that those who responded on 'satisfactory' oral health status indicated that 16% 'unsatisfactory', 28% 'average' and 68% 'satisfactory' on oral-related appearance. Students' self-rated oral hygiene management ability and irregular teeth conditions were also found relevant in causing discomfort in interpersonal activities, whereas students responded 'satisfactory', 0.00%; 'average', 31.82%; 'unsatisfactory' 68.18% (p <0.05). Conclusion: This study suggests that oral-related appearance can have an impact on oral health status and that oral-related appearance can be a contributing factor to improve oral health status and therefore results in promotion of general health. In the future, further research should be considered about perception on oral-related appearance, oral health status and any resulting behavior changes.

This study aimed to examine the relation between subjective oral hygiene status of the elderly and oral health impact profile and to present it as basic data for the improvement of quality of life and oral care. The study subjects were 231 elderly people aged 65 and over. This study measured the oral health behavior and subjective oral hygiene status based on cross analysis by calculating the median of OHIP-14 to divide the above-median group into a subgroup and the below-median group into a superordinate group. Correlation and regression analyses were performed to examine the effects on the oral health impact profile. The oral health impact profile according to oral health behaviors was not significant. The oral health impact profile based on the subjective oral hygiene states is currently affected by oral hygiene status, masticatory problems, toothache, xerostomia and halitosis. As a result of regression analysis to confirm the effect on the oral health impact profile, much experience of masticatory problems, toothache, xerostomia and gum diseases is the most influential. This shows that the subjective oral hygiene status is not healthy as the oral health impact profile is high. It is considered necessary to establish an oral health promotion program to improve the quality of life of the elderly and active oral care methods in the future.
This study was investigated in order to provide basic data for prevention of periodontal disease and maintenance through proper lifestyle by finding the relevance of periodontal health with lifestyle habits. Data were collected from total of 326 subjects in their forties and fifties by using questionnaire and examination of periodontal health status. Results were analyzed by using IBM SPSS Statistics 19.0. The smoking status were statistically significant to gingival index (p<0.01), pocket depth (p<0.001), and clinical attachment loss (p<0.001). Smoking amount per day were statistically significant to gingival index (p<0.05), pocket depth (p<0.01), and clinical attachment loss (p<0.001). Duration of smoking were statistically significant to gingival index (p<0.05), pocket depth (p<0.01), and clinical attachment loss (p<0.001). Drinking cycle were statistically significant to gingival index (p<0.05), and clinical attachment loss (p<0.05). It is investigated that smoking (p<0.05) influence on clinical attachment loss. Dental care institute needs to make patients be aware of the fact that excessive smoking and drinking affect the periodontal health status for prevention of periodontal disease and maintenance of oral health. Therefore systematic educational programs to stop smoking and drinking should be prepared.

Background: The purpose of this study was to compare the clinical safety and effect with and without additional submucosal midazolam to oral chloral hydrate and hydroxyzine when used for pediatric conscious sedation in a clinical dental environment. Methods: Thirty one cases of pediatric conscious sedations were performed in this study. Selection criteria included good health (ASA I), under 6 years old, 20 kg of body weight, uncooperative behavior and the need for sedation to receive dental treatment including anesthesia and restorative or surgical procedure for at least two teeth. In each visit, patients were randomly assigned into one of two groups; CH group: chloral hydrate (60 mg/kg), hydroxyzine (1 mg/kg), CH-M group: chloral hydrate (60 mg/kg). hydroxyzine (1 mg/kg) and submucoal midazolam (0.1 mg/kg). 50% nitrous oxide-oxygen was maintained during the sedation period Sedations were monitored using a pulse oximeter for estimating pulse rate (PR) and percutaneous oxygen saturation ($SpO_2$). Behavior response rated using Houpt's scale and need of restraint was assessed every 2 minutes through 30 minutes of operative procedure reviewing the videotape recording. Evaluation of overall behavior success was performed using modified overall behavior rate of Houpt's scale. Data was analyzed using t-test. Results: PR and $SpO_2$ for both groups remained within the normal values. The mean scores for sleep and movement of CH-M group were higher than those of CH group (P < 0.05). There were no significant difference in mean score for crying between two groups. The mean scores of overall behavior of CH-M group was higher than those of CH group (P < 0.01). Reinstraint of CH-M group was less required than that of CH group (P < 0.05). Conclusions: Oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) combined with submucosal injection of midazolam was safer and showed more improved sedation effect than oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) without midazolam for sedation of pediatric dental patients.
This study was performed to observe the micro-structure change of surface, behavior of oxide change of element, the component transformation of the alloy and the bonding strength between the porcelain interface in order to investigate effects of indium, tin on interfacial properties of porcelain fused to low gold alloy. Hardness of castings was measured with a micro-Vicker's hardness tester. The compositional change of the surface of heat-treated specimen was analyzed with an EDS and an EPMA. The interfacial shear bonding strength between alloy specimen and fused porcelain was measured with a mechanical testing system(MTS 858.20). The results were as follows: 1) The hardness value of alloy increased as increasing amount of indium addition. 2) The formation of oxidation increased as increasing indium and tin contents after heat treatment. 3) Diffusion of indium and tin elements increased as increasing indium and tin contents in metal-porcelain surface after porcelain fused to metal firing. 4) The most interfacial shear bonding strength was increased as increasing a composition of adding elements, and a heat-treatment time, and an oxygen partial pressure. From the results of this study it was found that the addition of alloying elements such as indium and tin increase hardness of as-cast alloy, produce surface oxide layer of adding elements by heat-treatment which may improve interfacial bonding strength between alloy and porcelain.

Objectives: To compare the levels of anxiety on GAD-7 scale among undergraduates of dental, medical and engineering students during COVID-19. The secondary objectives were to correlate the factors influencing level of anxiety and to assess the coping strategies practiced by undergraduates' students of Karachi duri.ng COVID-19 outbreak. Methodology: The cross-sectional based survey was conducted online among the medical, dental and engineering undergraduates' university students of private sector in Karachi through purposive sampling technique during COVID-19 lock down period. The GAD-7 validated tool was used along with the demographic variables, related stress factors and the coping skills practiced during this outbreak. Total 571 questionnaires were found completed in all sections. The data was analyzed on SPSS version 23. P-value <0.05 was considered as statistically significant. Results: The mental health of the students was assessed on GADS-7 scale as normal, mild, moderate and severe levels. From the total (n=18-3.2%) were normal, (n=132-23.1%) had mild, (n=343-60.1%) had moderate and (n=78-13.7%) had severe anxiety level on GADS-7. The levels of anxiety on GAD-7 scale were all positively associated with the related stressors at p-value of 0.000. Moreover the results depicted that there was a moderate and positive correlation found (0.456, 0.447, 0.512 and 0.452) for all related stressors and GAD-7 scale. Taking breaks from watching, reading news regarding the outbreak of COVID-19, meditation and engaging in some other activities were the most frequently used coping strategies for all levels of anxiety among three cohorts of undergraduates'. Conclusion: Undergraduates has shown 96.9% drastically increased level of anxiety during the outbreak of COVID 19 pandemic. Taking breaks from watching, reading news regarding the outbreak of COVID-19 was the most frequent behavior practiced by the students.
The elderly population with dementia is rapidly growing in South Korea. The aim of this study was to investigate the relationship between dementia and oral health in 197 subjects aged ${\geq}65$ years. The questionnaire included questions on subjective health status, subjective health concern, subjective oral health status and behavior, mastication ability, Oral Health Impact Profile-14 (OHIP-14), and Korean Dementia Screening Questionnaires (KDSQ). Oral examination was conducted by a single dentist to evaluate upper or lower denture use, and determine the numbers of remaining and functioning teeth, including implant and fixed prosthesis. The subjects who required a dementia test (KDSQ-C [cognition] of ${\geq}6$) had significant differences in systemic disease prevalence rate, subjective health status, subjective health concern, KDSQ-V (vascular disease) score, KDSQ-D (depression) score, subjective oral treatment need, key food mastication ability and OHIP-14 score compared to the healthy subjects. The proportion of denture wearers, total remaining teeth, total functioning teeth, toothbrushing frequency, oral pain severity, symptoms of periodontal disease, subjective oral health status, and subjective oral health concern showed no significant differences between the two groups. KDSQ-C and OHIP-14 scores showed a strong positive relationship, while KDSQ-C score and total remaining teeth or key food mastication ability showed a weak negative relationship. In the multiple regression analysis, the KDSQ-D, KDSQ-V, and OHIP-14 scores influenced the KDSQ-C scores. We suggest a relationship between oral health and cognitive impairment.
By extracting the variables related to the work stress generated from dental hygiene, identifying their relationships, this study aims to contribute to academic progress on work stress. The test results of this study are as follows for each hypothesis: 1. Among the work stress sensing factors, role ambiguity showed correlation to the active coping strategy and the passive coping strategy, whereas it did not have any correlation to the evasive reation. However, the physical resource environmental factor showed correlation to the active coping strategy, whereas it did not have any correlation to the other reation. 2. The passive coping strategy, among the work stress coping strategies, influences the role ambiguity, B type, work ambiguity, physical resource environmental factor by about 18.7%. 3. The active coping strategy, among the work stress coping strategies, influences the social support, role ambiguity, work place of health center factor by about 18.9%. 4. The evasive reaction, among the work stress coping strategies, was influenced by only the 36 years old over factor by approximately 4.2%. 5. It was found in all work stress sensing factors that the group with lower social support had a more degree of experiencing stress than the group with higher social support. In case of the behavior pattern, the type A experienced more stress than the type B only in role ambiguity. 6. It was found that the group with the higher social support tended to choose more active coping strategy than the lower social support. In case of behavior pattern, the type B coped more actively than type A in the passive coping strategy.
One of the best way to prevent dental caries and periodontal disease is removing dental plaque. Toothbrushing is also one of the crucial ways to gel rid of dental plaque and improve dental hygiene. The purpose of th is study was to examine how many bacteria were attached to toothbrushes used by dental palque acidogenecity and related behaviors to toothbrush use. Subjects in this study were 30 college students in their twenties, on whom a survey was conducted to find out how they cleansed their toothbrushes, how long they cleaned toothbrushes after brushing, and how to keep them. And then dental palque acidogenecity by caries activity test was implemented and the number of bacteria attached to their toothbrushes was tested. The findings of the study were as follows : 1. Concerning correlations between dental palque acidogenecity and the number of remaining bacteria in the toothbrushes used by students, the number of bacteria was lower in the group of students with no caries activity than in the group with mild caries activity. 2. As for relations between the way of cleansing toothbrushes and the number of bacteria, there was no statistically significant gap between the group of students who wetted their toothbrushes with water and rubbed the heads of them and the group of students who just only wetted their toothbrushes with no further actions. 3. Regarding the relationship of toothbrush cleansing time to the number of bacteria, the number of bacteria was lower in the group of students who cleansed their toothbrushes for 15 seconds or more. 4. As to the influence of the number of toothbrush used by students, there was no significant difference between the group using just one toothbrush and the other group using two or more toothbrushes. 5. As for correlations between the way of keeping toothbrushes and the number of bacteria, no significant gap existed between the group thai kept their toothbrushes separately and the other that didn't.
