Background: General anesthesia is a necessary method for successful dental treatment for children, compromised patients and the disabled who have difficulty in cooperation. The aim of this study was to assess dental treatment under general anesthesia at the department of pediatric dentistry, Ajou university hospital on children and the disabled. Methods: 217 general anesthesia from June 2010 to June 2014 were assessed for this study. Patient's distribution, treatment pattern, reasons for general anesthesia, distribution of combined operation, duration of anesthesia, treatment, frequency of general anesthesia and agents for general anesthesia were examined. Results: The proportion of male, the disabled were higher and above 19 years age group was the highest. Combined operation with otolaryngology was highest. Main reasons for general anesthesia were mental retardation for the disabled and uncooperative behavior for the non-disabled. Percentage of restorative treatment was the highest. Average anesthesia duration was 186 minutes and average treatment time was 143 minutes. Most of the airway was maintained by nasotracheal intubation and induction was done by sevoflurane. Conclusions: General anesthesia for dental treatment has been increasing for children, the disabled who have a difficulty of cooperation. The demand for dental treatment under general anesthesia is expected to continuously increase. Therefore, continuous research and studies should be done to establish efficiency and safety of general anesthesia and provide an enhanced environment for treatment.

The purpose of this study was to identify the accidents happened in the college dental laboratory technique classes and to realize the level of safety education for the dental laboratory technique major students. The research data were collected from a self-administered survey distributed to the conveniently selected college students whose majors were dental laboratory technology in Suwon, Daejeon, Daegu, Kimcheon, and Icsan. The study participants were 422 freshmen, sophomore and junior students in the selected cities. All collected survey responses were encoded and analyzed in SPSS 12.0. The findings were as follows. 1. The students who had any accidents in their laboratory classes were 36% and the other 64% answered 'no.' 2. Most injuries which the participants had were not significant. 3. The medical treatment periods of most injury cases were less than one week; however, approximately 20% of the self-reported injury cases reported that their treatment periods were longer than one week. 4. The body parts frequently injured from accidents were hands with 84.7% and arms, eyes, face, head, and legs in order. 5. Concerning the materials involved in the laboratory classes, most accidents happened when working with wax in 59.9%, with plaster in 52.3%, with wire in 39.8%, with alcohol in 34.6%, and casting iron in 22.2% in order. 6. The accident-prone laboratory methods were polishing with 53.5%, pickling or sanding with 17.4%, and casting or burning with 5.8% in order. 7. Most students wore their laboratory gowns well; however, few students wore mask before dust-involved jobs. Furthermore, only 57.1% students answered their laboratory fans worked during the polishing job. 8. Approximately 54% participant students answered that they took laboratory safety education when necessary only from the class instructors. 9. The 76.1% students responded that they needed laboratory safety education at least 1-2 times every semester. 10. The survey participants answered that the primary factors for injury prevention in their laboratory were taking safety education, wearing safety equipments, and providing safety-focused facilities.

The purpose of this study is to propose a management method to maintain the pleasant indoor air quality of the dental clinic by measuring and analyzing the indoor air quality of the dental clinic. The measurement was conducted in two rooms, a lobby where many residents stay in the reception room for waiting for medical treatment, and a VIP room where treatment activities are mainly performed. Measurement items are Temperature, Humidity, $CO_2$, CO, $NO_2$, $CH_2O$, VOC, $PM_{10}$ and measurement were taken on April 27, 2018. As a result of analyzing the temperature and humidity of the dental clinic, it was analyzed that the average indoor temperature was maintained at $25^{\circ}C$ and the humidity was kept at around 50%, maintaining proper indoor temperature and humidity environment. $CO_2$ was 855ppm in the VIP Room, which satisfied the maintenance standard. In the case of the lobby, it was analyzed to be 1,160ppm, which exceeded the maintenance standard and it is judged that the carbon dioxide generated by the respiration of the people staying in the lobby is the main reason. The mean concentration of formaldehyde in the VIP room was analyzed as $436{\mu}g/m^3$, exceeding the maintenance standard, and $2,100{\mu}g/m^3$ for the VOC exceeded the recommended standard. It was analyzed that the concentration was relatively higher due to the use of disinfectant and other drugs. The mean concentration of PM-10 in the lobby was analyzed as $65{\mu}g/m^3$ and it was analyzed that it satisfied the maintenance standard. To maintain a pleasant indoor air quality in a dental clinic it is necessary to minimize the effects of formaldehyde, VOC, $CO_2$ in the VIP rooms and lobby. For this purpose, the entire ventilation system and air purification system of the dental clinic should be installed. In case of the VIP room, local exhaust ventilation should be installed and workers should wear personal protective equipment.

Methods: The survey was performed from June 25 through October 30, 2004. A total of 548 disabled people participated in the study with details of 419 living in eight residential care centers located in Gyeongsangbuk-do and 129 children from a special school and two day-care centers. All subjects underwent oral examination and surveyed through a questionnaire. Parents of 129 children with disabilities were also surveyed through a separate questionnaire. Results: The dental caries experience rate was 82.1% of total 548 subjects. By age, those in their 20s experienced a high rate of dental caries with 87.5%. By educational level, those with a middle school education experienced a high dental caries rate with 91.8% (p<0.05). Of total subjects who experienced dental caries, 78.9% had experience in dental caries treatment. By age, those in their 10s showed a high rate of dental caries treatment with 87.4%(p<0.05). By educational level, those with a high school education showed a high rate of dental caries treatment with 87.7%(p<0.05). Those in residential care centers had a high rate of dental caries treatment with 82.1%, which is significantly higher than 68.8% of those who used day-care centers. A tooth extraction rate was 38.0% of total subjects. Those in their 40s had a higher rate of tooth extraction(p<0.01). Those in residental care centers had a significantly higher rate of extraction with 43.4%, compared with 20.2% of those in day-care centers. Of total subjects, 61.5% had plaque. A high rate of plaque formation was observed in those in their 40s(92.0%), those with a high school education(84.0%) and those with multiple disabilities(77.8%)(p<0.01). Among total subjects, 47.6% maintained healthy periodontal tissue. Those in their 40s and those with multiple disabilities had diseased periodontal tissue(p<0.01). Of 129 disabled children, 43.8% had plaque with parents who were not oral health-conscious while 18.6% had plaque with parents who were oral health-conscious, showing a significant difference(p<0.05) Conclusion: The results of the study suggest the need for educating parents with disabled children about oral health and strengthening programs for oral health for teachers working at special schools and day-care centers.

The purpose of this study was to evaluate smoking of dental technicians in 2005, and we have distributed questionnaires about smoking in 2005-KDTA general meeting and analyzed them. All 555 respondents who attended KDTA general meeting were selected by random sampling. However we dismissed 41 because of invalidness, so we got 504 people. Therefore, we have got conclusions below: 1. The rate of smokers who attended in 2005 KDTA was 33.93%, 46.3% in men, 1.44% in women. When we compared to other specialist groups, the rate of dental technician smokers was higher than them. 2. When we analyzed the ages of first smoking, 55.56% of the people started to smoke when they were in 24 years old. This result was very similar to the rate of dentist smokers in 2005 KDA research. 3. According to the answers of smokers and people who wire smokers in the past about quitting smoking period and willness in future, 60.82% among all members failed to quit smoking and also 69.2% among all members did not leap over 3 months but, they have thought to quit smoking for 6 months. 4. According to the answers about antismoking training related to environment in dental and clinical labs, most dental technicians(92.66%) have never been trained, also 37.70% among all members have not fulfilled their duty at self office. They have not recognized the danger of the indirect smoking. 5. When we asked chiefs in dental and clinical labs, the reason why they, didn't do the antismoking training their staffs, 32.1% of them replied that they were so busy, and 42.13% did because of their staffs, abhorrence and needlessness. 6. As Pan-dentistry members, over 80% agreed to the thought of the antismoking, also had medical knowledge about smoking. So we have the conclusion that dental technicians have identification as the Pan-dentistry members. 7. Most dental technicians expected KDTA to play a role about the antismoking training for their members. We have two suggestions to KDTA about the antismoking problem for members according to above conclusions. First, KDTA should prepare the antismoking training in the curriculum. Second, KDTA should support the antismoking programs of schools for students.
