Objectives : This study is aimed to seek how to promote oral health care by leading the clients with dental fears to change their behaviors in oral hygiene care based on the analysis of the relationships between the dental fears and oral health care behaviors of the clients who visit the Dental Hygiene Education Room. Methods : This study analyzed the 361 dental hygiene records of the subjects with finished treatment and accurate records among a total of 370 clients who had received dental hygiene care at the Dental Hygiene clinic in Y University from March 2007 till June 2009. According to their general features, the study analyzed whether they had any dental fears and why such fears occurred and conducted Chi-square test to compare their oral hygiene care experiences and behaviors with dental fears. Data analysis was made using the SPSS 12.0K for Window, with level of significance set at 0.05. Results : 1. In terms of dental fear or non-fear, the comparison by gender showed that women had a higher level than men, with 76 women(47.2%) answering yes; the comparison by age showed that the age group of 30 years old or older had a higher level than other groups. 2. In terms of dental fear reasons, "the past pain experiences" recorded 34.2%, showing the highest rate. 3. In addition, dental fears had influences on regular dental examination, scaling and dental hygiene education and the subjects without dental fear showed higher levels in terms of tooth-brushing frequency and time. Conclusions : To control "the past pain experiences", future dental treatment should place priority on preventive treatment and get clients to cope with pains through the preliminary education with pains. Besides, to make an effective oral health care of the clients with dental fears, dental hygienists should control the fears of the clients and perform an appropriate oral health care for them using the communication techniques to make friendly and trustworthy impressions.

The objective of this study was to examine possible causes of fear of dental treatment in middle school students. The subjects were a total of 347 students who were selected by convenience sampling from among the students of the middle schools located in Cheongju, Korea. They were administered a self report survey. The results showed that overall dental fear was higher among female students than male students. With respect to associative dental fears, they felt fear the most when they waited sitting on the dental chair. In fears of specific dental stimuli, needles were the most fearful stimulus. In the areas of fears of specific dental stimuli and overall dental fear, the subjects with indirect pain experiences felt fear more. There exists a need to develop dental health care programs that will help to manage and decrease fear of dental treatment.

Objectives: The purpose of this study is to investigate the effect of preventive treatment experience on scaling fear level. Methods: A total of 259 adults who had visited the dental clinic were analyzed. The results were summarized as follows. Statistical analysis of the collected data was performed using the SPSS WIN 20.0 statistical program. The general characteristics, scaling experience, and the characteristics of the subjects were analyzed. Frequency of scaling according to general characteristics was analyzed by independent sample t-test, Scaling fears according to treatment experience were tested by t-test. Correlation analysis was performed for scaling fears according to the reliability of dental hygienist. Regression analysis was carried out to investigate factors affecting scaling fear. Results: Level of fear during scaling was higher in females (3.03) than in males (2.54) and that after scaling was scored higher in females (2.68) than in males (2.34) by general characteristics (p<0.001). The adults who were not healthy in oral health showed the highest levels of fear during (3.29) and after (3.00) scaling by oral health status (p<0.001). Adults who had brushing education experience showed lower fear level than those who did not after scaling (p<0.01) according to the experiences of preventive treatments. With respect to the correlation of trust level to the dental hygienists with the scaling fears, it showed higher in the trust level (-0.688) as lower level of scaling fear (-0.642) in the scaling (p<0.01). Confidence level of dental hygienist (-0.661), brushing education experience (-0.121), and oral health status (-0.121) were influenced upon the regression analysis. Conclusions: Oral health education and dental hygiene education are increasing. It is thought that active efforts are needed to promote and maintain oral health.

Hyperventilation is produced by several distinct causes: anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The dental fears about acute pain, bleeding, needle, drill and dental surgery lead to the severe anxiety and increased blood catecholamine level. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the gentle care, a hyperventilation were occurred during the surgical extraction of impacted third molar with pericoronitis. We suggest that the dental patients with anxiety disorder must be attention for the manifestation of hyperventilation, especially in the psychologic disabled patient.

Tremors are trembling movements and are seen in association with alcoholic intoxication, certain drugs, thyrotoxicosis, multiple sclerosis, hysteria, and nervous tension. Dental fears, such as, pain, drill, unknown, dependency, helplessness, mutilation and oral change, induce the neuroendocrine response (release of epinephrine and norepinephrine, etc). The clinical manifestations of epinephrine or other vasopressor overdose include : anxiety, tenseness, restlessness, throbbing headache, tremor, perspiration, weakness, dizziness, pallor, palpitation and respiratory difficulty. Signs of local anesthetic overdose appear clinically whenever the anesthetic level in the blood rises to an appropriate level in an individual. The clinical signs of moderate overdose levels include : talkativeness, apprehension, excitability, slurred speech, tremor and muscular twitching. This is a case report about the severe tremor care after the endodontic treatment under right mandibular block anesthesia in a 56-years old female patient.

Objectives: The purpose of this study was to investigate the overall research trends and factors influencing dental fears in the last 10 years (2007-2017) and provide recommendations for future research. Methods: The literature review focused on dental fear research in Korea. Inclusion criteria of selected studies were as follows: studies that examined fear in middle school students or older, studies undertaken between 2007-2017, and studies that examined trends and factors relating to dental fears. Results: Findings from this literature review showed that the most commonly used tool for measuring dental fear was the Dental Fear Survey (DFS). A lack of trust towards the dentist increased dental fear among patients. Women managed fear better than men. Past pain experiences increased dental fear. The most frequent intervention for reducing fear was sound (41.7%). Most of the intervention studies demonstrated a reduction of fear, with the exception of interventions using ear plugs. Fear was increased in studies involving ear plugs. Conclusions: Based on the results of the study, specific measures should be taken to alleviate past pain experiences, such as the fear of anesthetic injections and sensations of the dental drill. Continuous research is needed to reduce dental fear.

Dental fear is one of the main barriers to the use of dental services, leading patients to avoid periodical dental check-ups or treatments, thus making oral health worse, and sometimes becoming the reason that dental professionals fail control the behavior of patients. Therefore, a dental fear must be controlled carefully in order to promote oral health and effective dental treatment. This study was taken from 313 people 13 to 18 year olds to measure their levels of dental fear. After analyzing the characteristics of dental fear and its related factors, as well as other factors which influence dental fear, we acquired the following results. 1. The level of dental fear was high, compared with advanced countries with relatively good oral health. 2. The strongest physiological response experienced during a dental treatment was the tension of muscles. These dental fears were mainly related to anesthetic needles and drills. 3. Levels of dental fear became higher, the number of times for the dental services utilization had reduced, avoid regular dental examination and perceived oral disease symptoms increased. 4. One of the biggest influences on dental fears turns out to be direct painful experiences and beliefs about dentists.

Objectives: This research is to provide the basic data for the improvement on oral health by examining the relationship between the dental fear and the dental service utilization, and to discuss a strategy for dental health in order to lower the level of dental fear. Methods: Data were collected by conducting a structured survey of 1,607 people between the age of 13 and 70 who have experiences in visiting a dental institution. Both univariate and multivariate analyses were employed to analyze the relationship between the number of times dental service and dental fears. Results: The average level of dental fear the respondents reported was $52.16{\pm}15.71$ and 31.5% of the response was at the level of high dental fear. A strong physiologic response during the dental treatment was muscle tension and the stimulations that strongly arouse the dental fear were the anaesthetic needle and the sound of drill. A result of analysis on the relationship between the dental fear and the dental service utilization shows that as the level of dental fear became higher, the number of times for the dental service utilization for the last year had reduced. Also when a patient has an experience of putting off or canceling an appointment due to dental fear and as a physiologic response during the dental treatment became stronger, the result shows a tendency that the number of times for the dental service utilization for the last year had reduced. Conclusions: It has been observed that dental fear is one of the main barrier to use dental service. Therefore, a physio-psychological factor like the dental fear should be included in the task of promotion of dental health, and in analyzing the dental service utilization behavior. A discussion about how to lower dental fear was made with respect to oral health promotion. At individual level, improvement of communication skill by dental service providers should be made with rearrangement of clinic environment into more cozy one.

Hyperventilation is defined as ventilation in excess of that required to maintain normal blood $PaO_2$ and $PaCO_2$. It is produced by several distinct causes: anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The dental fears about acute pain, needle, drill and dental surgery lead to the severe anxiety and increased blood catecholamine level. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the gentle care, two cases of hyperventilation were occurred during local anesthesia for incision and drainage of acute odontogenic infectious lesions. We suggest that the dental patients with acute odontogenic infection must be attention for the manifestation of hyperventilation, especially in the medically compromised conditions.

Extension of advanced odontogenic infection from deep neck fascial spaces into the mediastinum is heralded by chest pain, dyspnea, fever, and radiographic demonstration of mediastinal widening. The critical care should be done in a team approach by multiple medical and dental departments, such as, oral & maxillofacial surgery, otolaryngology, anesthesiology, chest surgery, and infection medicine. Especially, fluid & drug therapy, adequate incision & drainage and systemic supportive psychosedation care are important. But, acute hyperventilation can be produced by several distinct causes: severe anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The orofacial fears about acute pain, trismus, dysphagia, swelling and oral surgical treatment lead to the severe anxiety and increased blood catecholamine level by stress. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the care, hyperventilation was occurred during psychosedation and local anesthesia for incision and drainage of the masticatory fascial space abscess with deep neck infection & mediastinitis. We suggest that the dental patient with advanced odontogenic infection must be attention for the manifestation of hyperventilation, especially in the medically compromised conditions.
