Objectives: The purpose of the study is to investigate the influencing factors of subjective awareness of dental health status on the use of dental hygienic devices. Methods: A self-reported questionnaire was completed by 320 patients who visited dental clinics in Seoul and Gyeonggi-do from May to June 2014. Except incomplete answers, 284 copies were analyzed by SPSS WIN 18.0 program. The questionnaire was adapted from Park & Youn, and Chae. The questionnaire consisted of five questions of the general characteristics of the subjects, one question of subjective dental health status, eight questions of awareness of dental hygienic devices, and eight questions of use of dental hygienic devices. Results: Although the awareness of self dental health state was shown to statistically significantly affect the awareness of dental hygiene devices(p<0.001) which is the dependent variable, it was shown to not affect the use. Conclusions: Based on such results, to improve and maintain the dental health, an individual's subjective dental health state should be identified and provide accurate and objective information on the dental hygiene devices that are suitable to individual dental state, as well as make the patient's use of dental hygiene devices increase through continuous boosting of motivation.

Stainless steel wire has been used in industry, dental and medical parts. Especially, it has been used widely for the dental orthodontic materials. The orthodontic wire requires good mechanical properties, such as elastic strength, combined with a high resistance to corrosion. To increase elastic strength and good corrosion resistance, drawing methods(one-step and two-step drawing) have been used and the electrochemical characteristics of drawed wire have been researched using potentiodynamic method in 0.9％NaCl and field emission scanning electron microscope. The one-step drawed wire showed the formation of rough surface. The hardness and tensile strength of two-step drawed wire increased. For the case of two-step drawed wire, the corrosion resistance and pitting potential increased compared with one-step drawed wire due to the drawing induced small surface roughness, such as scratch. The passivation and active current density decreased as the reduction in area for drawing increased.

Objectives: Oral diseases can be prevented, and early treatment through dental checkups is important. This study was investigated the relationship between dental checkups and unmet dental care needs in Korean adults. Methods: From the data of the 7th Korean national health and nutrition survey (2016-2017), the final 9,300 of the 16,277 participants selected as the method for extracting stratified colonies by complex sample design. A structured questionnaire interview was used, and chi-square test and multiple logistic regression analysis were performed. Results: The relationship between dental checkups and unmet dental care needs for the last one year was analyzed by controlling demographic characteristics, variables related to health conditions, and "use of dental clinics for the last year." The unmet dental care needs were 7.57 times higher (CI: 6.49-8.83) for non-users of dental clinics for 1 year, and 1.32 times (CI: 1.13-1.54) for dental checkups for 1 year compared to non-dental checkups patients. Conclusions: As described above, there was a close relationship between adult dental checkups and unmet dental care needs. Therefore, it is suggested that it is necessary to expand educational publicity and prepare policy strategies such as visiting dental checkups to improve the adult dental checkups.

This study focused on the change of environment and cognition of dental hygienists about dental calculus removal after the national health insurance. We conducted online and offline surveys for 290 dental hygienists working in dental clinics in Seoul, Gyeonggi and Incheon areas. Differences in perceptions were assessed by independent t-test and ANOVA. 62.1% answered that the health insurance coverage of dental calculus removal was appropriate, and 49.6% said that the desired number of health insurance coverage about the dental calculus removal should be applied twice a year. 54.3% said that the age after 20 years-old was not appropriate in national health insurance coverage of dental calculus removal, and 49.3% said that the appropriate starting age of dental calculus removal should be applied from high school students. 26.3% said that the number of national health insurance applications should be increased yearly, 20.5% said that oral care education should be added. Most of the dental hygienists said that the number of scaling patients increased, but that the quality of the scaling did not deteriorate. According to general characteristics, in the recognition of the removal of calculus, the dental hygienists having a career for 7~8 years felt less change. The dental hygienist wanted to expand the scope of national health insurance about scaling removal so that more subjects could remove dental calculus removal. Dental hygienists wanted that national health insurance should be systematically supplemented in order to contribute to the promotion of oral health of the people.
