In this study, the patterns of people who get dental services from unqualified dental practitioners were identified by using "2006 National Dental Health Investigation". There were 4,543 people in total and the group was divided into two groups - those who had experience of receiving dental services from unqualified practitioners and of those who had not. The most pattern model was CHAID. It was patterned that 39% of those who are more than 68 years would experience such unqualified dental service, and it was found that 3% of those who are less than 33 years experienced such a service. It was found that 45% of those who are 55 or 68 years and woman would experience such unqualified dental service, and 32% of those who are 55 or 68 years and man experienced such a service. With the increase in health awareness, the burden of medical bills is also rising. However, cases of unqualified dental treatments that could cause extremely dangerous symptoms are also rising recently. Therefore it is most important to anticipate those groups who are most exposed to unqualified dental services, and educate them with appropriate information and publicise about the danger.

The purpose of this study was to analyze outpatient referral patterns of children in Jeonbuk National University Dental Hospital. All patients under 16 years old who were consulted from the external facilities were reviewed based on the electronic medical record of Jeonbuk National University Dental Hospital from 2015 to 2018. Total 720 boys and 460 girls with an average age of 7.4 years were referred from local dental clinic (85.2%) for treatment severity (90.2%). 3.2% of patients has disability with the highest number of intellectual disabilities. The patients were usually referred at the pre-treatment stage with higher rates if they had disability or medical problem. Referral rate by chief complaints was highest in surgery, followed by reparative treatment and orthodontic treatment. 2^nd referrals in pediatric dentistry had a higher rate of referrals to minor surgery and pulp treatment than of first referrals. The time point of 2^nd referral was relatively delayed with increased ratio of 'during treatment'. These results suggest necessities of appropriate case selection and referral based reasonable criteria for pediatric dentist.

Introduction The aim of this study, personal trait and their dental care based on experience level of dental fear is to analyze the differences. Catastrophizing is an irrational belief that something is far worse than it actually is. Because it makes it possible to analyze patients' anxious thoughts and tendencies. Methods The Dental Fear Survey(DFS) and Anxious Thoughts and Tendencies(AT&T) were used as measuring tools, and the independent sample t-test and ANOVA were performed on the basis of the mean value of the summated scale scores and the standard deviation. On the factors to dental anxiety, the multiple regression analysis was performed. Results Demographically, the total DFS score was higher in women($25.73{\pm}8.27$) than in men. Also, AT&T was higher in women($31.01{\pm}7.05$) (p<0.05). Dental fear was intense in the group of patients who visited dental clinics only problems($25.29{\pm}8.57$) than in those regular visited($22.29{\pm}7.78$). In relation to dental experiences, the DFS score was significantly higher in children. In many cases, patients experienced therapeutic pains in children($26.40{\pm}9.54$) (p=0.004). Also in many patients, dental anxiety began to occur in adolescence(44.3%). The multiple regression analysis result, it was found that dental treatment pain and their AT&T wielded great influence upon dental fear.

X-ray image analysis is a very important field to improve the early diagnosis rate and prediction accuracy of periodontal disease. Research on the development and application of artificial intelligence-based algorithms to improve the quality of such dental X-ray images is being widely conducted worldwide. Thus, the aim of this study was to design a super-resolution algorithm for predicting periodontal disease and to evaluate its applicability in dental X-ray images. The super-resolution algorithm was constructed based on the convolution layer and ReLU, and an image obtained by up-sampling a low-resolution image by 2 times was used as an input data. Also, 1,500 dental X-ray data used for deep learning training were used. Quantitative evaluation of images used root mean square error and structural similarity, which are factors that can measure similarity through comparison of two images. In addition, the recently developed no-reference based natural image quality evaluator and blind/referenceless image spatial quality evaluator were additionally analyzed. According to the results, we confirmed that the average similarity and no-reference-based evaluation values were improved by 1.86 and 2.14 times, respectively, compared to the existing bicubic-based upsampling method when the proposed method was used. In conclusion, the super-resolution algorithm for predicting periodontal disease proved useful in dental X-ray images, and it is expected to be highly applicable in various fields in the future.
