Objectives: The purpose of the study is to investigate the dental fear and related factors of dental hygienists using dental fear survey. Methods: A self-reported questionnaire was completed by 279 dental hygienists from January 15 to March 28, 2015. The study instrument was dental fear survey. Data were analyzed using SPSS 19.0 program by t-test, one way ANOVA and stepwise multiple regression analysis. The questionnaire included general characteristics of the subjects, subjective oral health status, use of dental care services, subjective oral health status, and recent dental treatment. Results: Alcohol consumption was the most influential factor to the dental fear. The subjective status of oral health and direct pain sense also contributed to the dental fear. Conclusions: To reduce the dental fear, it is important to have high confidence toward the dental treatment performance in the dental hygienists.

Objectives : The neural substrate of fear is thought to be highly conserved among species including human. The purpose of this review was to address the neural substrates of fear based on recent findings obtained from animal and human studies. Methods : Recent studies on brain regions related to fear, particularly fear conditioning in rodents and humans, were extensively reviewed. Results : This paper suggests high consistency in anatomical structure and physiological mechanisms for fear perception, response, learning and modulation in animals and humans. Conclusions : Fear is manifested and modulated by well conserved neural circuits among species interconnected with the amygdala, such as the hippocampus and the ventromedial prefrontal cortex. Further research is required to incorporate findings from animal studies into a better understanding of neural circuitry of fear in human in a translational approach.

Objective : Although studies have explored responses to fear had been assessed using various psychophysiological methods, results have been inconsistent. The present study examined psychophysiological responses in healthy subjects after viewing fear stimuli in a video clip for set up future fear related psychophysiological studies. Methods : We monitored three psychophysiological variables (electroencephalography, skin temperature, and heart rate variability) in adults who watched either a control stimulus movie clip or a fear-inducing movie clip. Results : In 16 healthy adults, theta activity decreased significantly after the fear stimulus as compared to the normal stimulus. However the participants showed no differences in heart rate variability or skin temperature between the fear and normal control stimulus situations. Conclusion : In the limbic area, theta activity corresponds with information processing, integration into previous memories and long-term potentiation. In this study, we suggest decreased theta activity represents amygdalo-hippocampal activity, associated with fear, short-term memory, and memory extinction in the healthy adults. Further studies are needed to evaluate the interaction of fear, memory, and the pathophysiology of anxiety disorder in patient with anxiety disorders.

Purpose: The objectives of this study were to explore the relationships between the fear of falling and daily activities, and physical functioning of older people in community. Method: A descriptive study design was used in this study. 295 people aged over 65 and living in community participated. Data of demographic characteristics, fear of falling, activity daily living, physical functioning were collected. Result: 13.2% of the participants reported that they have falling accident last one year. 75.6% of participants reported fear of falling. 67.7% of them expressed restricting activity because of fear of falling. There were no significant relationship between fear of falling and BADL(Basic Activity Daily Living) but fear of falling and IADL(Instrumental Activity Daily Living) were related. It was also found that older people with higher fear of falling expressed more pain and uncomfortable feelings especially on their lower body and had higher scores of morbidity of neurologic diseases such as neuralgia and cerebrovascular diseases. Conclusion: There were significant relationships between fear of falling and IADL, and physical functioning on lower body, and morbidity of neurologic diseases such as neuralgia and cerebrovascular diseases.

Fear conditioning and extinction, which are adaptive processes to learn and avoid potential threats, have essential roles in the pathophysiology of anxiety disorders. Experimental fear conditioning and extinction have been used to identify the mechanism of fear and anxiety in humans. However, the brain-based mechanisms of fear conditioning and extinction are yet to be established. In the current review, we summarized the results of neuroimaging studies that examined the brain changes-functional activity and structures-regarding fear conditioning or extinction in healthy individuals. The functional activity of the amygdala, insula, anterior cingulate gyrus, ventromedial prefrontal cortex, and hippocampus changed dynamically with both fear conditioning and extinction. This review may provide an up-to-date summary that may broaden our understanding of pathophysiological mechanisms of anxiety disorder. In addition, the brain regions that are involved in the fear conditioning and extinction may be considered as potential treatment targets in the future studies.

The purpose of this study was to describe preschoolers' perceptions of fear from their own perspective. Qualitative data from 213 preschoolers 4 to 6 years of age were obtained by semi-structured interviews. The fear inventory was analyzed by content analysis and frequency. The most common fears of preschoolers in this study were fear of ferocious animals and imaginary figures, such as tigers, lions, snakes, spirits and ghosts. Fear of ghosts was the primary fear of both boys and girls. Results showed that most fears were caused by disgust-related visual images. Worry about injury and pain was another common pathway to fear. At-risk preschoolers scored significantly higher than normal preschoolers on fears of criticism and getting an injection.

Objectives : The purpose of this study is to seek analysis of related factors for dental fear and to know the fear component affecting the treatment of the dental treatment. Methods : Total of 320 females and males aging from 10 to 40 years old with dental treatments done from May to July 2010 have participated with self-entry survey method utilizing the Dental Fear Survey questionnaire. The data received was analyzed using the descriptive statistic, t-test, ANOVA and multiple correlation analysis with level of significance as p<0.05. Results : The dental fear factor were significantly high in woman by $2.79{\pm}0.92$ and in 40's age group by $2.82{\pm}0.84$ (p<0.05). Participants with frequent tooth ache, experiencing pain while treating the tooth ache and breaking the dental treatment appointment showed higher fear factor. Thoughts of having poor dental health condition caused bad influence on fear factor. Overall, the factors affecting the fear of the dental treatments were gender, an ache while treating, number of missed appointment, and distrust of the dentist, stimulation factor were the factors affecting the treatment. Conclusions : The fear factors in the dental treatment were higher with gender, related characteristics of the oral health and distrust of the dentist. Therefore accurately recognizing the sensitive patient with dental treatment, proper management of the toothache, effort to increase the creditability of the doctors and separately treating patient customized for each individual patient will reduce the fear of the dental treatment.

Pediatric and adolescent dental anxiety and fear have been researched in the connection with behavior modification for a long time and this dental anxiety can persist until the adult hoods resulting in extreme fear of and avoidance of dental treatments and causes oral health deterioration. However, the domestic researches regarding adolescent dental anxiety and fear are insufficient. For this reason, this study aims to examine the level of fear and the influential factors affecting their dental fear and to utilize the result as the basic materials in the dental management. The subjects were the students from a middle school located in Gyeonggi-Do. The school was selected by convenient sampling and self-answered questionnaire was filled in by the students. The distribution of responses in each category of fear was examined by frequency analysis. The analysis was conducted using cross tabulation in order to examine the difference between male students and female students and using independent sample t-test in order to compare the fear score of each category. The study results showed the fear score of female students for the category 'causing irritation during the dental treatments' was significantly higher in statistics(p<0.05). Therefore, these results should be reflected to the dental care environments in order for the adolescent to reduce the dental anxiety and fear.
