This study intends to improve the radiation safety management and the recognition for handling radiation using structured questionnaires to dental hygienists working at Jeollabuk-do from September 1 to October 31 in 2014. As a result, 63% of respondents have not received education for radiation safety management. Moreover, the practical degree for radiation safety management was $2.58{\pm}1.11$, while the degree of knowledge was $3.74{\pm}0.83$ of total 5.0. The results of insecurity for radiation danger were high as $3.88{\pm}0.92$, and insecurity for fetus during pregnancy shows the highest value as $4.43{\pm}0.71$. From the results of statistical significance level, the knowledge degree of radiation safety management is affected by total numbers of radiograpy for a day (p<0.05), and the practical degree of radiation safety management is affected by age group, academic background, monthly income, continuous service year, practice area, present position, and status of radiography in present (p<0.05). In addition, the knowledge degree of radiation safety management have a negative correlation (r=-0.232) with the practical degree, but have a positive correlation (r=0.262) with the insecurity for radiation danger. The high knowledge degree of radiation safety management (${\beta}=0.252$, p<0.001) and the short radiography work period (${\beta}=-0.341$, p<0.05) were the influential factors to the insecurity for radiation danger. Consequently, countermeasures are necessary to encourage dental hygienists to put their radiation safety management knowledge into the practice and to reduce the insecurity degree for radiation danger. Furthermore, it is important to prevent psychological and physical risks by radiation exposure through the improvement of radiation safety management level and recognition for handling radiation to improve medical environment.

This research was attempted to investigate the correlation between food habits as well as preferences and health conditions of middle-aged people. 380 people living in Dae-gu, kimch$\breve{o}$n and k$\breve{u}$mr$\breve{u}$ng gun in the 40's or 50's were selected for this research as subjects from July 1 to August 15, 1990. The data analysis was made by way of frequency, percentage, ${\chi}^2-test$ and Pearson correlation using SAS package. The summarized results are as follows. 1. Among the total subjects of this research, 200 people (52.6%) were male and 180 people (47.4%) were female. The regional distribution was like this; 115 people (30.3%) lived in large city, 154 people (40.5%) in small and medium city and 111 people (29.2%) in rural region. 2. The survey on food life attitude on the subjects showed that they had a relatively good attitude, and there were little significant differences (p<.05) between men and women. But there were significant differences (p<.001) between rural region and city. 3. On the preferences for taste, food and cooked food the subjects showed the lowest preferences for processed milk-fat food and the highest for soybean and processed soybean food. 4. The research on health condition 1) 30.8% of the subjects were obesity. And this research showed that the percentage of obesity was higher among men (33.5%) than women (27.8%), and higher in cities (40.4, 34.4%) than rural region (16.2%), (p<.05, p<.01). 2) 90.8% of the subjects showed negative according to Diabetes inspection. 3) 2.0% of the subjects were hypertensive, and the percentage was higher among women than men, and higher in rural region than cities. 4) 12.6% of the subjects were anemia, and the percentage was higher among women (17.8%) than men (8.0%), and higher in rural region (23.4%) than cities (7.0, 9.1%). 5) DMFT index and DMF rate of dental caries was higher among women (DMFT index; 10.6 DMF rate; 88.9) than men (DMFT index; 7.3 DMF rate; 81.5), and higher in rural region (DMFT index; 11.8 DMF rate; 90.1) than cities (DMFT index; 7.4, 7.9 DMF rate; 79.1, 85.7). 6) According to the survey on self-diagnosed health status of subjects, the percentages of articular·neuralgia (48.9%) was the highest. And that of stomach digestion troubles (31.1%), headache (22.4%), anxiety excitement (12.9%), spastic constipation (12.4%), insomnia (9.7%), melancholia (7.9%) and etc (1.6%) followed. 7) People had allergied food which contained animal protein such as pork, chicken, mackerel, siakworm pupa, clam and so on. 8) In female cases, 46.7% of women became already menopausal and 13.3% of them was under menopause. 5. This research showed that there were significant correlation between food life attitude and health condition in obesity, anemia and dental caries but not in blood pressure. 6. And this research also showed that there were significant correlations between food preference and health condition in obesity, anemia and dental caries but not in blood pressure.

Patients with extreme anxiety who are unable to cope with dental treatment under non-pharmacological behavioral management method may require sedation, or other forms pharmacological behavioral management method. The aim of this retrospective study was to investigate the effect of concomitant administration of 0.1 mg/kg intramuscular midazolam with or without sevoflurane insufflation sedation on sedation depth and cardiopulmonary function in pediatric patients. We analysed the records of anesthesia on patients who received dental treatment under deep sedation using sevoflurane insufflation from January 2013 to March 2014. Thirty-six children, aged 3 to 6 years, undergoing dental treatment were sedated using either sevoflurane insufflation alone (Group S, n = 18) or a combination of intramuscular injection of 0.1 mg/kg midazolam plus sevoflurane insufflation (Group SM, n = 18). Upon comparison, the average entropy value of group SM was lower than that of group S, but there were no statistically significant difference between the two groups (p > 0.05). The average heart rate and mean arterial pressure of group SM were higher than those of group S (p < 0.05). Concomitant intramuscular injection of 0.1 mg/kg midazolam with sevoflurane insufflation sedation is not sufficient to enhance the quality of sedation.

Background: Local anesthetic injections may induce pain in children, leading to fear and anxiety during subsequent visits. Among the various approaches recommended to reduce pain, one is the use of a Buzzy Bee^TM device that operates on the concept of gate control theory and distraction. The literature regarding its effectiveness during the deposition of local anesthesia remains limited; hence, the aim of the present study was to determine the efficacy of extraoral cold and vibrating devices in reducing pain perception during the deposition of local anesthesia. Methods: A split-mouth crossover study in which 40 children aged 3-12 years requiring maxillary infiltration or inferior alveolar nerve block for extractions or pulp therapy in the maxillary or mandibular posterior teeth were included. The control intervention involved the application of topical anesthetic gel for one minute (5% lignocaine gel), followed by the administration of local anesthetic (2% lignocaine with 1:80,000 adrenaline) at a rate of 1 ml/ minute. Along with the control protocol, the test intervention involved using the Buzzy Bee^TM device for 2 minutes before and during the deposition of the local anesthetic injection. The heart rate and face, legs, arms, cry, and consolability revised (FLACC-R) scale scores were recorded by the dentist to assess the child's pain perception. Results: The mean age of the participants in Group A and Group B was 7.050 ± 3.12 years and 7.9 ± 2.65 years respectively. A reduction in the mean heart rate and FLACC-R score was observed during the deposition of local anesthetic solution in the tissues when the Buzzy Bee^TM was used in both groups at different visits in the same subjects (P < 0.05) The Buzzy Bee^TM device was effective in reducing the heart rate and FLACC-R scores when used during maxillary infiltration and inferior alveolar nerve block local anesthesia techniques (P < 0.05). Conclusion: The use of extraoral cold and vibrating devices significantly reduces pain perception during local anesthetic deposition in pediatric patients. Considering the results of this study, the device may be incorporated as an adjunct in routine dental practice while administering local anesthesia in children.

The study on correlation between the parents' character of orthodontic patients and patients cooperation. Although dentists have excellent skill and technique, patients' cooperation is always demanded. Patients' poor cooperation results in poor treatment result. Cooperation between psycho-social state of parents and patient's cooperation was studied. The parent's psychosocial state is evaluated with scl-90-r. The cooperation is measured by appointment time compliance, appliance taking rate, breakage of appliance, and fee paying. Parents' psychosocial contents are somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic-anxiety, paranoid ideation, psychoticism, and additional item. Statistics was done by SPSS WINDOW version 12.0 program. The result showed no correlation between patients' cooperation and their parents' psychosocial state. There is no correlation between father's psychosocial state and patients' cooperation except psychoticism. There is no correlation between mother's psychosocial state and patients' cooperation. However, there was correlation among cooperation variables: appointment time compliance, appliance taking rate, breakage of appliance, cost paying. Appliance taking rate and cost paying showed positive correlation. Our findings suggest that patients' cooperation does not followed their parents' pychosocial state. Other combined factors should be considered like pychosocial state of patient and doctor-patient relationship.

This study examined the symptoms of temporomandibular disorder and the relationship with the psychological character using Symptom Check List-90-Revision (SCL-90-R). The self-administered questionnaire survey was implemented from March 1, 2014 to June 30, 2014 targeting 294 University Students in Daejeon and Gangwon area aged 20-31 years old (Men 140 persons, Women 54 persons). The data showed that the teeth grinding and the unilateral chewing out of corrupt practices in the mouth in relation to the use of the lower jaw showed a significant correlation (p<0.01) with the depth of symptoms of temporomandibular disorder, as the result of the simple psychodiagnosis inspection (SCL-90-R), and a significant correlation (p<0.05) with the depth of symptoms of temporomandibular disorder in the item excluding phobic anxiety (PHOB). The somatization (SOM) criteria out of individual psychological characteristic appeared to have the significant plus (+) effect on the depth of symptoms of temporomandibular disorder as a result of implementing multiple regression analysis by controlling the individual characteristic variables to check the influence of the psychological character of the study object on the symptom of temporomandibular disorder.

The purpose of this study was to examine the association between oral health status and health related quality of life (HRQoL). The study used a nationally representative sample of Koreans (2013 Korea National Health and Nutrition Examination Survey) aged 19~64 years (n=3,252). Dependent variable was HRQoL, which was assessed with each component of EuroQol-5 dimension (EQ5D). Independent variable was oral health status (oral pain, chewing problem, speaking problem, and perceived oral health). After adjustment for confounders (socio-demographic factors, oral health behaviors, health behaviors, and physical conditions), the risk of having poor HRQoL was greater in adults with poor oral health status. The odds ratio (OR) of having pain/discomfort were 1.50 (95% confidence interval [CI], 1.22~1.86) for respondents with oral pain, 1.72 (95% CI, 1.33~ 2.22) for respondents with chewing problem, 1.79 (95% CI, 1.22~2.62) for respondents with speaking problem, and 1.36 (95% CI, 1.09~1.70) for respondents with poor perceived oral health. The OR of having anxiety/depression were 1.74 (95% CI, 1.28~2.38) when having a chewing problem, 1.72 (95% CI, 1.12~2.64) when having a speaking problem, and 1.54 (95% CI, 1.14~2.08) when rating his/her oral health poor. Among Korean adults, two of the EQ5D components were associated with oral health status. Future study is needed to examine the detailed causal relations between oral health status and HRQoL longitudinally.

Objectives: Stress is a psychological reaction to stimuli such as anxiety or threat felt by a person either physically or mentally when placed in a difficult situation. Although a relationship between stress and dry mouth has been reported, it remains understudied. The purpose of this study was to investigate the association between stress and subjective dry mouth among the elderly living in a rural region. Methods: A total of 214 people aged ${\geq}60years$ living in a rural area were recruited with an informed consent for a cross-sectional analysis. Information about stress and subjective dry mouth was obtained by an interview survey with a constructed questionnaire. Data on other potential confounding factors (including oral factors) such as socio-demographic data, health-related behaviors, the number of remaining teeth, and subjective chewing ability were also gathered at the same time. Logistic regression models were used to analyze the relationship of stress and dry mouth using SPSS. Results: The Crude odds ratio (OR) of stress awareness affecting subjective dry mouth was 2.59 (95% confidence interval: 1.43-4.68). After adjusting for sex, education, income, smoking, and alcohol intake, the adjusted OR was 2.52 (95% confidence interval: 1.30-4.87) which was statistically significant. Conclusions: Elderly people who were stressed had an approximately 2-fold increase in experiencing subjective dry mouth when compared to their stress-free counterparts.

Purpose: The purpose of this study was to assess influences of psychological factors on sleep disturbances in young adults through the revised version of the Minnesota Multiphasic Personality Inventory (MMPI-2). Methods: Two hundred and ninety nine college students in Gyeonggi-do completed the MMPI-2 and a questionnaire related to sleep disturbances and collected data were analyzed by logistic regression. Results: The odds of tooth grinding increased significantly with the increase of T-score of hysteria (Hy) scale. The increase of T-score of hypomania (Ma) and social introversion (Si) scale significantly contributed to the risk of insomnia. The occurrence of insomnia increased significantly as T-score of somatic complaints (RC1) and psychoticism (PSYC) scale increased. The odds of tooth grinding increased significantly as T-score of anxiety (ANX) and family problems (FAM) scale increased. The occurrence of insomnia decreased significantly with the increase of T-score of type A behavior (TPA) scale. The increase of T-score of dominance (Do) scale significantly contributed to the risk of tooth clenching. The odds of tooth grinding decreased significantly as T-score of MacAndrew alcoholism-revised (MAC-R) scale increased, whereas it increased significantly as T-score of addiction potential scale (APS) increased. No scale of MMPI-2 significantly affected the occurrence of snoring. Conclusions: T-scores of Hy, ANX, FAM, Do, MAC-R, and APS scales on MMPI-2 affected the risk of bruxism. T-scores of Ma, Si, RC1, PSYC, and TPA scales on MMPI-2 influenced the occurrence of insomnia. The psychometric instrument such as MMPI-2 is helpful in understanding and managing bruxism and insomnia.

The aim of this review is to introduce about the issue of benzocaine and methemoglobinemia. Through blocking the pain during dental treatment, fear and anxiety of patients will be reduced. Thus, anesthetic agent containing benzocaine is commonly used while controlling the pain of patients during treatment. However, on May 28, 2018, the Ministry of Food and Drug Safety reported a medication safety report about restricting the use of benzocaine-containing agents in infants under 24 months and children. Also, they recommended a cautious use to adolescents and adults to prevent methemoglobinemia (MHb). This report was published due to an advice from Food and Drug Administration (FDA) on May 23, 2018. When using agents containing benzocaine, dentists must consider the probability of MHb and prepare for early diagnosis and appropriate action. Since 1930s, methylene blue is known to cure MHb patients. Therefore, the proper use of methylene blue for emergencies and diagnosis methods for early diagnosis of MHb should be familiar to dentists planning for the use of topical anesthetic agents. Dentists should be trained for emergency situation of MHb caused by the use of benzocaine.
