In spite of the progress in techniques and materials of the prosthodontic rehabilitation of patients with complete edentulous arches, prosthodontists still face patients' complaints about dissatisfaction and discomfort from their dentures. In the past several decades, prosthodontists tried to find the factors that influence the patient's satisfaction with dentures. However the results are contraversial especially with the psychological factor. In this study using 'patient denture satisfaction questionnaire' and Hopkins Symptom Checklist, we tried to find the correlation between the patient's denture satisfaction and the patient's psychological aspects. 23 complete edentulous patients who have visited the Department of Prosthodontics, Yonsei University Dental Hospital from September 1998 to June 1999 for complete denture treatment were asked to complete the questionnaires 4 to 6 weeks after the upper and lower complete delivery. After the measurement of validity of the questionnaires, correlations between the patient's general satisfaction with their new upper and lower complete dentures and the other satisfaction questions including the satisfactions with esthetics, retention, mastication, speech, comfort and other people's opinion and between the patient's general satisfaction with their new upper and lower complete dentures and the 5 symptoms of Hopkins Symptoms Checklist including somatic, obsessive-compulsive, interpersonal sensitivity, depression and anxiety were analyzed. Among the several satisfaction questionnaire items, comfort with the lower denture showed highest relation to the patient's general satisfaction with dentures. However, only the anxiety scale of Hopkins Symptoms Checklist among the other symptom scales was related to the patient's general satisfaction with dentures. The two questionaires used in this study turned out to be valid means of analyzing patient's denture satisfaction and psychological status before and after the complete denture treatment.

The purpose of this study was to investigate the effect of alcohol drinking motivation on the drinking behaviors of female college students. It is necessary to examine the drinking behavior of female college students not only for their academic performance and health status but also for future reproduction concerns. The subjects of this study included 296 college students in their 20s. Research data was analyzed using SPSS 24.0 and AMOS 22 statistical programs. Results of this study found academic and human relationships had the greatest effect on the stress level of female college students. In addition, the perception of drinking was more influential on the drinking problem, and female college students who perceived anxiety through the drinking problem tried to change the behavior of drinking. Also, the perception of drinking by the influence of alcohol was more significant than that of drinking by college students who perceived anxiety through drinking problem. Second, if drinking is beneficial in the internal or external motivation of the individual, it maintains drinking behaviors and changes the behavior of drinking when experiencing the problem of drinking. Through these results, we aim to contribute to the reduction of the negative risk of alcohol by understanding the drinking preference of female college students and examining the drinking culture according to drinking motives.

Children commonly experience orofacial injuries and often need emergency treatment. Due to fear and anxiety, children tend to be uncooperative in emergency rooms. Ketamine hydrochloride is a well-known sedative agent at medical-based emergency rooms which has been used for procedural sedation. In this paper, we will discuss the sedation of uncooperative young patients, who needed dental treatments in the emergency room at Wonju Severance Christian Hospital, using ketamine. We collected the records of patients under 18-years-old who visited the emergency room for dental treatment from January 2010 to May 2014. The data was categorized by age, sex, required dental treatments and application of ketamine sedation. Among 659 pediatric patients who visited for emergency dental treatments, 118 patients were treated under sedation using ketamine. Majority of patients were under the age of 6 (110 patients), and the most frequent cause of sedation was suture of oral laceration (105 patients). Though ketamine should not be used by dentists alone, dentists in emergency rooms can easily meet the patients under deep sedation using ketamine. Hence, dentists in emergency rooms need to be aware of the clinical effects, considerations, and potential adverse effects of ketamine.

Background: Fearful and anxious patients who find dental treatment intolerable without sedative and analgesic support may benefit from moderate sedation. Target controlled infusion (TCI) pumps are superior to bolus injection in maintaining low plasma and effect-site concentration variability, resulting in stable, steady-state drug concentrations. We evaluated the safety and efficacy of moderate sedation with remifentanil and propofol using TCI pumps in non-hospital dental settings. Methods: A prospective chart review was conducted on 101 patients sedated with propofol and remifentanil using TCI pumps. The charts were completed at two oral surgeons and one general dentist's office over 6 months. Hypoxia, hypotension, bradycardia, and over-sedation were considered adverse events and were collected using Tracking and Reporting Outcomes of Procedural Sedation (TROOPS). Furthermore, patient recovery time, sedation length, drug dose, and patient satisfaction questionnaires were used to measure sedation effectiveness. Results: Of the 101 reviewed sedation charts, 54 were of men, and 47 were of women. The mean age of the patients was 40.5 ±18.7 years, and their mean BMI was 25.6 ± 4.4. The patients did not experience hypoxia, bradycardia, and hypotension during the 4694 min of sedation. The average minimum Mean Arterial Pressure (MAP) and heartbeats were 75.1 mmHg and 60.4 bpm, respectively. 98% of patients agreed that the sedation technique met their needs in reducing their anxiety, and 99% agreed that they were satisfied with the sedation 24 hours later. The average sedation time was 46.9 ± 55.6 min, and the average recovery time was 12.4 ± 4.4 min. Remifentanil and propofol had mean initial effect-site concentration doses of 0.96 µ/.ml and 1.0 ng/ml respectively. The overall total amount of drug administered was significantly higher in longer sedation procedures compared to shorter ones, while the infusion rate decreased as the procedural stimulus decreased. Conclusion: According to the results of this study, no patients experienced adverse events during sedation, and all patients were kept at a moderate sedation level for a wide range of sedation times and differing procedures. The results showed that TCI pumps are safe and effective for administering propofol and remifentanil for moderate sedation in dentistry.

With Korea's rapid entry to aged society, elderly population has become a major age group both in the whole society and medical field and its importance will be constantly stressed out. Elderly population is also important in the field of oral medicine which deals with chronic and recurrent diseases in the orofacial region of non-dental origin but there exist few studies indicating epidemiology of elderly patients in this regards. This study aimed to investigate change of age distribution of new patients in a university-based dental hospital and oral medicine clinic for last decade and to investigate clinical epidemiology of elderly patients (${\geq}$ 65 years) of oral medicine clinic. This study was performed retrospectively using medical records of the new patients in Dankook University Dental Hospital in 2001 and 2011. According to the study, percentage of elderly new patients increased in both dental hospital and oral medicine clinic and degree of the increase was greater in oral medicine clinic than in the whole hospital (p=0.000). 13.5% of adult patients ${\geq}$ 18 years of oral medicine clinic were elderly patients ${\geq}$ 65 years. 83% of elderly patients were suffering from one or more systemic diseases. Although TMD was the most common reason for elderly patients who visited oral medicine clinic, oral soft tissue diseases, dry mouth, burning mouth syndrome and oromandibular dystonia was more frequently diagnosed in elderly patients compared to adult patients aged 18 to 64 years. Pain severity and interference of Brief Pain Inventory and depression and anxiety scores of Hospital Anxiety Depression Scales were higher in elderly patients than in the adult patients (p<0.05). Increase of elderly patients with chronic oral diseases and pain needs more attention of dentists and specialists of oral medicine to improvement of assessment and development of tailored management because large portion of the elderly patients have systemic diseases, polypharmacy and impaired communication, possibly restricting treatment options.

The aim of this study was to analyze factors related to xerostomia in adults aged 30 years and over. The data were analyzed using the t-test, one-way ANOVA and multiple linear regression analysis in the SPSS version 12.0 program. The results were as follow. 1. The respondents who were older than 51 years old, unemployed and had less than 3 million won of average monthly income were more aware of xerostomia (p<0.05). 2. The respondents who answered poor and moderate for their general and oral health and the group with duplicate medication and comorbidity were more aware of xerostomia (p<0.05). 3. The respondents that had problems in chewing, communication, ordinary activities and complained of pain discomfort and suffered from anxiety depression were more aware of xerostomia (p<0.001). 4. The respondents that answered frequent dryness on their skin, eyes, lips, and nasal mucosa were more aware of xerostomia (p<0.001). 5. Xerostomia showed highest correlation with quality of life ($\beta$=0.436) followed by the number of medications ($\beta$=0.239), sense of entire body dryness ($\beta$=0.200), feeling of hopelessness ($\beta$=0.160) and number of oral mucosa disease symptoms ($\beta$=0.099) (p<0.05). According to the results of the study, xerostomia may cause deterioration in quality of life. Thus, it is advised to improve the patient management system among dental professions to prevent various complications caused by xerostomia and conduct regular health education on the cause and management method of xerostomia.

This study examined the effects of various individual differences on children's memory of a stressful experience. The participants for the current study were children (N=85) aged 4-9 years those who experienced a naturally occurring stressful experience from a dental procedure. There was overall negative relation between the level of stress and children's memory performance. However, more interestingly, the results of this study provided some further evidence that several cognitive (i.e., receptive language ability and working memory capacity) and emotional (i.e., children's general anxiety condition, children's self-report of pain and anxiety about the event) individual difference factors were associated with variations in children's remembering across ages. The results suggest that the relation between stress and children's memory might be impacted in part by children's various individual characteristics. Furthermore, the findings are discussed in the applied context that based on the results clinical and legal professionals can tailor interviews to best meet children's needs and capabilities, and create developmentally and individually sensitive guidelines for interviewing children in the legal system.

Natal teeth that are already present at birth and neonatal teeth that erupt shortly after birth may cause various complications. The purpose of this study is to evaluate the characteristics of natal/neonatal teeth in Korean infants who visited to Kyung Hee University Dental Hospital from 2006 to 2015. A retrospective review of clinical data, including the sex of the patients, chief complaints of the mothers, clinical appearances and locations of the natal/neonatal teeth, and associated complications and treatments, was collected. Overall, a total of 75 teeth were found in 48 patients and 69% of the infants had natal teeth, while 31% had neonatal teeth, all of which were mandibular incisors. Females showed more natal/neonatal teeth than males. Major reasons for visiting the dental clinic were parental anxiety, referrals from other clinics, Riga-Fede disease, and pain during breastfeeding. Extraction was the most common treatment choice; observation and grinding were also used.

The aim of this study was to investigate changes in treatment patterns within pediatric dentistry departments by analyzing the distribution of patients and treatment trends. To that end, treatment charts based on electronic medical records (EMR) from the Yonsei University Dental Hospital from 2008 to 2012 were collected and analyzed. The results showed a decrease in the number of new patients and patients cared for by non-specialists, while the number of foreign patients has increased. The under 2 years-old group accounted for a large portion of new patients. Dental caries, dental trauma, and malocclusion ranked as the top complaints. In terms of restoration treatment, the proportion of patients receiving composite resin, amalgam, and sealant has decreased, whereas self-curing glass ionomer and preventive resin restoration have increased. Single-visit endodontic treatment has been increasing, with a decreasing trend in multi-visit endodontic treatment. The rate of conservative pulp treatment, such as pulp capping and pulpotomy, has increased. For reducing patient anxiety, treatments under sedation have increased, especially with the use of nitric oxide. This investigation into the latest treatment trends and patient characteristics is expected to help pediatric dentists to make appropriate treatment plans.

Williams syndrome (WS) is a rare congenital disorder which is caused by microdeletion of approximately 1.6 MBP from the long arm of chromosome 7 at 7q11.23. It is characterized by cardiovascular anomalies, elfin face and mental retardation. The most typical oral signs in patient with WS are hypodontia, reduced mesio-distal dimensions both in the primary and permanent teeth, macroglossia, excessive interdental spacing, enamel hypoplasia and enamel hypomineralization. The majority of children with WS have mild to moderate mental retardation, generalized anxiety disorder, hyperactivity disorder and sensitivity to sounds. The purpose of this presentation is to describe dental treatment for a child with WS. A 9-year-old boy diagnosed with WS had caries on his first permanent molars. Because of the poor cooperation, these teeth were filled temporarily with glass ionomer, and treatment under general anesthesia was planned. Under general anesthesia, caries treatment of first permanent molar and extraction of primary molar was successfully performed and there was no postoperative complications related to general anesthesia. Open bite, hypodontia, excessive dental space, enamel hypoplasia, enamel hypomineralization were observed which were characteristic in WS.
