This study addresses the effectiveness of a VR model that is designed to relieve distress and improve communication during pediatric dental treatment for 3-9 year-old young patients. This is due to the challenging nature of the dental treatment for both young patients and pediatric dentists. The proposed model is designed to alleviate the unpleasant experience a young patient might go through during the dental treatment through providing a VR content to be displayed in on a head-mounted device during the treatment session. In addition, the model is designed to help decrease the frequent movement of the young patient during the dental treatment session by directing the patient's head to the immersive VR content. Furthermore, the model could solve the communication difficulties that might occur between pediatric dentists and young patients during the treatment session by showing live instructions related to adjusting body postures

Objectives: The purpose of this study was to provide a satisfactory and reliable dental care service for the patients and to establish a plan to raise the perception about dental infection control. Methods: The perception of infection control in the dental clinic of the patients was examined who visited to dental clinics, over 20 years old and living in Seoul and Gyeonggi province since December 2016. The questionnaire was used as the survey tool, and 274 questions in the questionnaire were analyzed. Results: Results of examined factors affecting the perception of dental infection control in dental clinics show that the perception of infection control in dental clinics is affected by the degree of university graduates (p<0.05), full-time workers (p<0.01), housewives (p<0.001), and oral health concerns (p<0.05), the perception of infection control of dental medical personnel (p<0.001) in order. Conclusions: Dental medical personnels must thoroughly wash their hands, wear uniforms, wear personal protective equipment, and thoroughly clean and disinfect the interior of a dental clinic.

Objectives : Based on data collected from patients who suffered from dental caries during the period between 1990 and 2008, the number of patients and their trends were analyzed as a source of evidence to conduct the oral health plan. Methods : A population of sample design for patient survey data was derived from computerized data saved at medical institutions accredited by National Health Insurance Corporation. Large institutions such as dental hospitals were included for the complete enumeration test, while the rest of medical institutions, for example, dental clinic, relatively small institutions, were used for the sample survey. Most of patients with dental caries were outpatients and their disease was treated at the dental hospital or dental clinic in general, therefore, main analysis was carried out at those institutions. Results : The rate of patients who suffered the dental caries has decreased to 56.8% in 2008 from 78.5% in 1990. The rate of patients who visited the dental hospital for treatment has increased to 4.8% in 2008 from 0.5% in 1990, whereas the percentage of those who visited the dental clinic has fallen to 97.9% from 99.5% during the same period. The ratio by age, in the meantime, it showed that patients aged 40s has increased to 13.5% in 2008 from 7.2% in 1990, and the number also has risen in 50s from 5.6% in 1990 to 9.9% in 2008. However, the number of children aged 0 to 9 who visited hospital for treatment of dental caries has fallen to 17.0% in 2008 from 33.9% in 1990. Conclusions : By figuring out the trends of patients with the dental caries during the period between 1990 and 2008, fundamental data for the oral health policy have been collected. As a result, the necessity of a new medical treatment system for managing the dental caries in terms of patient ages as well as the oral health policy and campaign was taken into consideration.

Lidocaine, a local anesthetic commonly used in dental treatments, is capable of causing allergies or adverse effects similar to allergic reactions. However, the frequency of such occurrences in actual clinical settings is very rare, and even clinical tests on patients with known allergies to local anesthetics may often show negative results. When adverse effects, such as allergy to lidocaine, are involved, patients can be treated by testing other local anesthetics and choosing a local anesthetic without any adverse effects, or by performing dental treatment under general anesthesia in cases in which no local anesthetic without adverse effects is available. Along with a literature review, the authors of the present study report on two cases of patients who tested positive on allergy skin tests for lidocaine and bupivacaine and subsequently underwent successful dental treatments with either general anesthesia or a different local anesthetic.

Dental treatment under general anesthesia is considered for behavioral control of disabled patients who have severe anxiety or involuntary movement. However, in case of simple treatment, inhalation or intravenous sedation, which has earlier onset and recovery, is preferred. Conventionally, nitric oxide is used for inhalation sedation, nowadays sevoflurane can also be used due to easily titratable for controllable effect and less complications. In this case report, two patients with mental retardation required simple dental treatment. Deep sedation with inhaled sevoflurane were successfully employed and patients were discharged without any complications.

Objectives: The purpose of the study was to investigate the influencing factors on anxiety and depression before and after prosthetic treatment in the patients. Methods: A self-reported questionnaire was completed by 248 patients with tooth loss and over 20 years old. The questionnaire was carried out before and after oral examination and dental prosthetic treatment from July to December, 2013. The study instruments included Beck's anxiety inventory and self-rating depression scale by Zung. The questionnaire was adapted and modified from Kwon's anxiety inventory and Lee's depression scale. Results: While the anxiety level increased from 69.4% to 78.2% in the normal people, the depression level changed from 53.2% to 64.1% in the normal people. The gender variable had a positive effect on anxiety and depression while educational level had a negative effect on them. The dental fear was closely related to anxiety and depression before and after the prosthetic treatment. The entire body health perception showed a negative effect on anxiety and depression. The distrust towards the dentist had an influence on the anxiety and depression in the prosthetic patients. Conclusions: The influencing factors on anxiety and depression in the prosthetic patients included gender, dental fear, entire body perception, and distrust towards the dentist.

Objectives: The goal of this study is to establish data baseline to ameliorate oral health policies for patient. The research was conducted in dental clinic at Seoul Metropolitan Children's Hospital - the major municipal hospital for the disabled. The outpatients' visiting patterns to the dental clinic were analyzed, compared to other medical departments. For further research related to TMD, the questionnaires were given to the subjects. Material and methods: Data for visiting patterns/frequencies was collected from patient records of 1419 outpatients who visited the dental clinic at Seoul Municipal Children's Hospital in 2011. Then TMD-related questionnaires were given to 127 outpatients who were over 13 years old. Results: 1. 219 out of 1419 patients (15.4%) who visited the dental clinic at Seoul Municipal Children's Hospital in 2011 were the disabled. 2. Compared to normal patients, disabled patients visited the dental clinic and rehabilitation medicine department more frequently.(p<0.05) However, there was no apparent difference in visiting frequencies between the disabled and the normal patients in the psychiatric department.(p=0.3237) 3. 44% of the TMD-related questionnaire subjects responded that they often consumed relatively hard or tough food, 53% answered they had unilateral chewing habit, 3% had bruxism, and 12% had clenching habit. Conclusion: In the dental clinic at Seoul Municipal Children's Hospital, 19% of outpatients over 13 years old had TMD such as clicking and pain. Also, the disabled patients' visits to the dental clinic were considerably more frequent, compared to the normal patients and to other medical departments. Accordingly, the result may suggest that the proper systematic supports from the government are essential to the dental clinic at municipal hospital for the disabled.

PURPOSE. Squamous cell carcinoma (SCC) of the tongue has a relatively high incidence of all oral cancers. Some studies have reported a relationship between intraoral dental prosthesis and SCC of the tongue; however, this relationship remains controversial. The purpose of this study was to investigate the relationship between SCC of the tongue and the positional aspects of dental prosthesis using a retrospective analysis. MATERIALS AND METHODS. A total of 439 patients with SCC of the tongue were diagnosed and treated in the Department of Oral and Maxillofacial Surgery, Seoul National University Dental Hospital. Patients were treated over a 12.5-year period ranging from January 1, 2001 to June 30, 2013. Statistical analysis was performed to examine potential differences between the groups. RESULTS. The number of patients with a crown and/or a bridge (134, 63.5%) was significantly different than the number of patients without a prosthesis (77, 36.5%). Even after accounting for different types of prostheses such as crowns, bridges, and dentures, no significant differences were observed between the position of the prosthesis and the location of the SCC of the tongue, with significance defined as a P-value less than .05 by the Pearson-Chi square test. CONCLUSION. Patients with crowns and/or bridges exhibited more frequent SCC of the tongue compared with patients without these prosthesis. These data support the hypothesis that mechanical trauma and galvanic phenomena play a role in the etiology of SCC of the tongue.

Background: People with special needs tend to require diverse behavioral management in dentistry. They may feel anxious or uncomfortable or may not respond to any communication with the dentists. Patients with medical, physical, or psychological disorders may not cooperate and therefore require sedation (SED) or general anesthesia (GA) to receive dental treatment. Using the healthcare big data in Korea, this study aimed to analyze the trends of SED and GA in special needs patients undergoing dental treatment. It is believed that these data can be used as reference material for hospitals and for preparation of guidelines and related policy decisions of associations or governments for special needs patients in dentistry. Methods: The study used selected health information data provided by the Korean National Health Insurance Service. Patients with a record of use of one of the eight selected drugs used in dental SED between January 2007 and September 2019, those with International Classification of Diseases-10 codes for attention deficit hyperactivity disorder (ADHD), phobia, brain disease, cerebral palsy, epilepsy, genetic disease, autism, mental disorder, mental retardation, and dementia were selected. The insurance claims data were analyzed for age, sex, sedative use, GA, year, and institution. Results: The number of special needs patients who received dental treatment under SED or GA from January 2007 to September 2019 was 116,623. Number of SED cases was 136,018, performed on 69,265 patients, and the number of GA cases was 56,308, implemented on 47,257 patients. In 2007, 3100 special needs patients received dental treatment under SED while in 2018 the number of cases increased 6 times to 18,528 SED cases. In dentistry, ADHD was the most common disability for SED cases while phobia was the most common cause of disability for GA. The male-to-female ratio with respect to SED cases was higher for males (M : F = 64.36% : 35.64%). Conclusion: The application of the SED method and GA for patients with special needs in dentistry is increasing rapidly; thus, preparing guidelines and reinforcing the education and system are necessary.
