Purpose: Picture Archiving and Communication System (PACS) is difficult to implement in the best of situations, but evidence is growing that the benefits are significant. The aims of this study are to analyze the current status of full PACS and establish successful installation standard of dental PACS. Materials and Methods : Materials and methods were based on the investigation of current working status and installation standard of PACS, and observation of variable issues to installation of dental PACS. Results: By September 30,2004, full PACS implementations in their facilities were 88.1 % in specialized general hospitals (37 installations out of total 42 hospitals), 59.8% in general hospitals (144 installations out of total 241 hospitals), 12.3% in medical hospitals (116 installations out of total 941 hospitals) and 3.6% in dental hospitals (4 installations out of total 11 0 hospitals) Only 4 university dental hospitals currently have installed and are operating full PACS. Major obstacle to wide spread of dental PACS is initial high investments. Conclusions: Clinical environments of dental PACS differed from medical situation. Because of characteristic dental practice, the initial investments for dental PACS are generally much greater than those of medical PACS. Also new economic crisis makes users scruple. The best way to overcome these limitations is to establish an economic installation standard for dental PACS. Also the clear technical communication between the customer and the supplier before both sides are committed to the obstacles are critical to its success.

Objectives: This study consisted of a literature review on oral health among people with disabilities, and to present the factors that should be considered in developing an oral health program for people with disabilities. Methods: The key words 'people with disabilities' and 'oral health' were searched in 4 Korean academic journals and 5 online search engines and a total of 635 papers were identified. Duplicate papers were removed, and the literature selection criteria were applied to the remaining papers. Finally, a total of 45 papers were used in the review. Results: First, people with disabilities were the most common research subjects, followed by dental students, dental hygiene students, dentists, dental hygienist and guardians and special education teachers. Second, the most frequently studied research topic was dental examination, followed by oral health behavior and behavior of using dental clinics. Third, research purposes included the status of oral health, the quality of oral health, dental treatment, the use of oral health service, and oral hygiene behavior and perception. Fourth, the most frequently discussed policy task was expansion of research subjects, followed by oral hygiene and policy development. Conclusions: To enhance the oral health of people with disabilities who have difficulty in keeping their teeth clean and healthy on their own, development of an oral hygiene training program is required not only for people with disabilities, but also for guardians and teachers. It is equally important to examine oral health behavior that could potentially affect the status of oral health and create a more accurate and systematic oral hygiene method. In addition, the government, together with various other research institutes, should conduct an oral health survey of a representative sample of people with disabilities to determine oral health status and facilitate improvements to oral hygiene programs.

Purpose: We retrospectively analysed patients' dental and periodontal status according to the presence of non-communicable diseases (NCDs) and the effects of NCDs on periodontal treatment outcomes. Factors influencing disease recurrence were investigated using decision tree analysis. Methods: We analysed the records of patients who visited the Department of Periodontology, Pusan National University Dental Hospital from June 2014 to October 2019. As baseline subjects, 1,362 patients with periodontitis and who underwent full-mouth periodontal examinations before periodontal treatment were selected. Among them, 321 patients who underwent periodontal examinations after the completion of periodontal treatment and 143 who continued to participate in regular maintenance were followed-up. Results: Forty-three percent of patients had a NCD. Patients without NCDs had more residual teeth and lower sum of the number of total decayed, missing, filled teeths (DMFT) scores. There was no difference in periodontal status according to NCD status. Patients with a NCD showed significant changes in the plaque index after periodontal treatment. The decision tree model analysis demonstrated that osteoporosis affected the recurrence of periodontitis. Conclusions: The number of residual teeth and DMFT index differed according to the presence of NCDs. Patients with osteoporosis require particular attention to prevent periodontitis recurrence.

Objectives : This research analyzed the general characteristics that closely affect the children's dental health and the mothers' dental health knowledge and dental health behavior to identify the correlation of the latter with the status of children's dental health in order to provide the basic data for the development of dental health business that would target children. Methods : Research subjects were selected arbitrarily from three nursery schools located in Busan metropolitan city, targeting 186 children between the ages of four to six and their mothers. The children were subjected to dental Inspection, and the status of their dental caries was studied whereas the mothers were subjected to the surveys on the general characteristics, dental health knowledge and dental health behavior. Results : 1. Level of mothers' dental health knowledge is higher when the mothers' educational level is higher(p=0.02) and when the household's monthly income is higher(p=0.009). 2. When the level of mothers' dental health knowledge is higher, children tended to brush their toothbrushing using proper method(p=0.025). Moreover, when the level of mothers' dental health knowledge is higher, they tended to take their children to dental clinic mostly for preventive measures than for treating cavity(p=0.023). 3. When the level of mothers' dental health knowledge is higher, children's dmft index was significantly low(p=0.02). When the mothers use fluoride-containing toothpaste, children's children' dmft index was even lower(p=0.02). 4. As the children tended to brush their teeth more often, dmft index was lower(p=0.003). When the reason that the children visited dental clinic was more to prevent, than to treat cavity, dmft index was even lower(p=0.000) Conclusions : When the above mentioned results are summarized, it is possible to know that the mothers' dental health knowledge and dental health behavior significantly affect children's dental health. Accordingly, it is necessary to develop maternal and child dental health program that factors in both the mothers and children in order to prevent children's dental caries and to increase their dental health, and continued care is required to discover and treat dental caries early on.

The purpose of this study,was to find out health status, characteristics related to working conditions, occurrence of low back pain and its related factors among dental hygienists working in dental clinics, and, thus, to provide basic information necessary to set up some plans for preventing the occurrence of low back pains and improving working conditions for dental hygienists. The data were collected from 310 dental hygienists working at dental clinics in Pusan and Kyungnam area, including Masan, Changwon, Jinhae and Jinju, with a self-administered questionnaire and were analyzed finally for 295 records with SPSS for Windows(7.52K) program. The results were as follows : Working condition was considered to be fair by 562% of dental hygienists were thought to threaten their health in the dental clinics. About seventy percent of dental hygienists worked over ten hours a day and 72.8% were standing while working over 7 hours, 65% considered working hours too long. Health status was thought be more than average for 82.3% while more than half perceived certain degree of stress frequently. The rate of complaining low back pains among dental hygienists was 87.8% with pains more than medium level for 39.3%. The variables significantly related to the degree of low back pains were height, uncomfortable postures, type of working postures and the height of working table, while some variables including height, hours of working on the feet, the presence of hazardous work environment, uncomfortable postures, the presence of hazardous works, the amount of working hours, type of working postures and work-associated stresses, were significantly related to the number of symptoms for low back pains. Multiple regression analysis showed that occurrence of low back pains was significantly influenced by 5 factors such as subjective status of health, work-related stresses, the degree of perception to work environment, the degree of perception to the amount of working hours and age. In conclusion, it might be necessary to manage working conditions effectively by reducing working hours, making good postures while working and removing stressful conditions in order to reduce risk factors for the occurrence of low back pains among dental hygienists. Therefore good working postures, assignment of appropriate rest time and some programs for early detection, care and education of low back pains should be provided for the dental hygienists.
