One of the most critical causes in determining the clinical outcomes of dental prostheses is the validity of models. However, studies that evaluated validity of digital models are few. The objectives of this study were to evaluate validity of edentulous digital models for full denture fabrication. Twenty stone models (edentulous model) were manufactured and scanned by dental blue light emitting diode scanner. Twenty digital models were manufactured. Six linear distances (inter-canine distance, inter-molar distance, two dental arch lengths (right, left), two diagonal of dental arch lengths (right, left) were measured for validity evaluation. The measurements of distances of stone models were used by digital vernier caliper and digital models were used by computer program. The mean${\pm}$deviations values of six distances were calculated. The means were compared by the Mann Whitney U test (${\alpha}=0.05$). All statistical analysis were performed using IBM SPSS Statistics ver. 20.0. Although digital models were smaller than stone models in six distances, there were no significant differences (p>0.05) and non exceeded the clinical acceptable range. The edentulous digital models for full denture fabrication can be considered clinically acceptable.

This study aimed to identify the convergence relationships among nutrition knowledge, health beliefs, diet self-efficacy, and diet management behaviors among Sri Lankans with hypertension (HTN). 91 adults diagnosed with HTN for more than one year participated in this study. A set of interviewer-administered questionnaire was used to assess general characteristics, nutrition knowledge, health beliefs, diet self-efficacy, and diet management behaviors. A stepwise multiple regression analysis was conducted to identify the factors that might influence diet management behaviors. There were statistically significant positive correlations between nutrition knowledge (r=0.26, p=.013), health beliefs (r=0.35, p=.001), diet self-efficacy (r=0.34, p=.001) and HTN diet management behaviors. Three variables, nutrition knowledge, health beliefs, and diet self-efficacy, explained 19.9% of the variance in HTN diet management behaviors (F=8.36, p=.001). Diet self-efficacy was the most significant influencing factor (${\beta}=.29$, t=2.75, p=.007), followed by nutrition knowledge (${\beta}=.25$, t=2.50, p=.014). The findings of this study can be used as valuable data for developing effective interventions to improve diet management behaviors of persons with HTN.

With the increase of visitors to rural tourism villages, the direct selling at sites is getting vitalized. Accordingly, their display stores is getting more important. Therefore, this study has selected 30 domestic rural tourism villages as study objects for the attitude survey of 200 farming suppliers and the site examination for the designs of those display stores in order to analyze their status and classify the types of necessity. Such operation status as sale item, sale method, method of supply and demand, major customer, sales scale, manager, opening hour, and operation cost were examined, to identity and for design factors the pattern, material quality and color were investigated. For the attitude of farming suppliers, the tactics of sales, the reason for being positive or negative, the functionality and the features of display stores were examined through brainstorming. IBM SPSS Statistics 20 Program was employed for Frequency, which indicated that village chiefs and store managers with the sales scale of 1 to 20 million won are dealing with female customers in their 40's and 50's and that those stores are open at the time of experience or year round without any operation expense. Permanent type and Fixed type were found to be the design factors of the display-case type with the material and the color of wood and orange respectively. The result of investigation analysis of farming suppliers' attitude showed the followings: the need of display stores is quite high, structure type and permanent type have high fitness and from the viewpoint of display-on-table type as a standard moving type was very convenient. The analysis of significant items at the characteristics of those display stores revealed that their locations, quality conservation, sanitation, users' convenience, designs and promotion are very important. The result of status analysis revealed that though there is a correlation among the types of display stores depending on the visiting season of tourists their installing is not desirable. Three types have been analyzed: Type 1 is a structure type only in the villages with continuous visitors, Type 2 a moving-table type only in the villages with temporary visitors and Type 3 is a fixed display-case type.

The purpose of this study was to evaluate the accuracy of model according to three types of dental scanner. A maxillary acrylic model was prepared and duplicated 10 times by silicone impression materials. Corresponding working casts were formed from scannable stone and got a 3-dimensional digital models using three different scanners. The distance of each measurement region was measured using vernier calipers and the respective program. One-way ANOVA and the Tukey honestly significant difference post hoc test (${\alpha}=0.05$) was performed using IBM SPSS Statistics 21.0. Overall, the stone cast is smaller than the digital models in measurement distance. And measuring point value of laser scanner showed the most similar values and measurement points value of digital vernier calipers. Digital model of white light scanner showed similar values in the measurement points value of the blue light scanner. In conclusion, the laser scanner showed the best accuracy among the three types of dental scanner. However, the difference between the digital models and the stone cast can be accommodated in making prostheses. Thereby, three types of dental scanner are available in a clinically acceptable range.

The purpose of this study was to examine the relationships between depression, stress, self-esteem, oral health-related quality of life (OHIP-14) in middle-aged women. Data were as collected by self-reported questionnaires from 205 middle-age women. The instruments were the Center for Epidemiologic Studies Depression scale (CES-D), Brief Encounter Psychosocial Instrument (BEPSI), Self-Esteem Scale (SES). The data were analyzed using t-test, one-way ANOVA, Pearson correlation coefficients and multiple regression with IBM SPSS Statistics ver. 21.0. Pearson correlation coefficient analysis found that oral health impact profile (OHIP) was significantly associated with depression (r=-0.560, p<0.001), stress (r=-0.595, p<0.001), self-esteem (r=0.522, p<0.001). The OHIP was explained 39.4% by stress (${\beta}$=-0.362, p<0.001), self-esteem (${\beta}$=0.203, p=0.009) using multiple regression analysis. These results indicate that the intervention program of oral health promotion for community-middle- aged women is needed from now on.

The aim of this study was to examine the image for dental hygienists and career consideration in academic high school students. A self-reported questionnaire was surveyed by 199 high school students in Gwangju. The questionnaire composed subject's general characteristics, image for dental hygienists, career consideration. The data were analyzed for independent t-test or Mann-Whitney test, one-way ANOVA or Kruskal wallis test and pearson's correlation coefficient by using IBM SPSS Statistics ver. 21.0 program. The average of total image was 3.36, personal images were 3.64, occupational images were 3.47, business images were 3.42, social images were 2.83 in the five-point scale. The image of dental hygienists was higher significantly in case of having a dental practitioner in the family, treatment experience less than 1 year, and treatment in dental hospital. The participants who considered to be dental hygienist were higher significantly in occupational and social images. There were positive correlations among the personal, occupational, business, social images of dental hygienists. These results showed that general images for dental hygienists were slightly positive but among them, social image was the lowest level. It showed that most students didn't consider to be dental hygienist. Therefore, we suggested to enhance positive recognition for dental hygienists be needed.

The purposes of this study were to assess dental fear and anxiety level of patients attending a dental clinic using the dental fear survey (DFS) scale, to apply interventions chosen by patients for reducing dental fear and anxiety and measure their effects. This study surveyed 34 patients who visited a dental clinic in Seoul about their self-rated health and their experience of dental fear, and measured the level of dental fear using DFS. Trained dental hygienists applied interventions desired by the patients for reducing dental fear and anxiety and, for each intervention, examined the patients' satisfaction (very helpful [5 point]~not helpful at all [1 point]). Collected data were analyzed using IBM SPSS Statistics ver. 21.0 through independent t-test or one-way ANOVA for difference in level of fear according to related characteristics, and through Wilcoxon signed rank test for comparison between before and after the intervention. The subjects' mean level of fear (DFS score) was 44.53, which was an average level, and the level of dental fear was relatively high for stimulus-response (2.72). The level of dental fear was higher in those who had experienced pains or indirect dental fear from dental treatment in the past, and those whose subjectively perceived health state was poor (p<0.05). With regard to the applied dental fear intervention, 'Helpful (3.57)' was the most common answer. Overall satisfaction before and after the application of dental fear intervention was generally high as 4.37 and 4.35, respectively, but it decreased slightly after the intervention. In order to lower the level of dental fear, it is considered effective to survey not only the level of dental fear but also patients' need of dental fear interventions and to apply a suitable intervention. It is also required to educate dental workers and to develop related manuals.
