    Abstract PDF
    Objectives: The purpose of the study is to investigate the awareness and practice of dental unit waterline management in dental hygienist. Methods: A self-reported questionnaire was completed by 377 dental hygienists in Seoul and Gyeonggido from March 2 to April 30, 2015. The data were collected by direct visit and informed consent was received after explanation of the study. The questionnaire consisted of general characteristics of the subjects, awareness of dental waterline, practice of dental waterline, and implementation of dental waterline disinfection. Data were analyzed using SPSS 12.0 program. Results: There was a significant correlation between the dental unit waterline disinfection and the appropriateness of the water used for dental treatment(p<0.01, p<0.001). The handpiece was the most commonly used device before treatment and the majority of the subjects answered that they didn't take water out of ultrasonic scaler and air-water syringe on a daily basis. Conclusions: The majority of the dental hygienists did not know the right understanding and proper practice of dental unit waterline management.

    전은영 | Lee, Su Young | 2016, 16(4) | pp.525~530 | number of Cited : 1
    Abstract PDF
    Objectives: The purpose of the study is to investigate remineralization effect according to application cycle of fluoride varnish in preschool children. Methods: The study subjects were fifty six children (92 teeth) having one or more early dental caries lesion. Fluoride varnish was applied to the primary area of maxillary and anterior mandibular teeth with the interval of one month, three months, and six months. Results: Dft index was 3.54 in male and 3.44 in female. The fluorescence loss(△F) value due to early caries lesions showed a significant difference in experiment groups Ⅰ and Ⅱ after the application of fluoride varnish, but there was no significant difference in experiment group Ⅲ. After fluoride varnish application, there was a significant change in experimental group Ⅰ and Ⅲ. The maximum fluorescence loss(△Fmax) from early caries lesions showed a significant difference after application of the fluoride varnish in all three experiment groups of Ⅰ, Ⅱ, and Ⅲ(p<0.001).

    Abstract PDF
    Objectives: The purpose of the study is to investigate the awareness and attitude toward health insurance coverage extension to scaling in dental service consumers. Methods: A self-reported questionnaire was completed by 349 adults in Jeonbuk from May 4 to 15, 2015. The questionnaire consisted of general characteristics of the subjects (7 items), Awareness of the dental health insurance system(8 items), Health insurance system coverage extension to scaling(8 items), Self-perception of oral health(7 items), Recognition toward yearly scaling benefit(10 items). Results: There were significant differences according to age in opinions on the appropriateness of the frequency of yearly scaling benefit, and the respondents who were in their 20s, who were unmarried and who brushed their teeth three times a day had significantly different opinions on the appropriateness of the fee of yearly scaling benefit. Their opinions on the expansion of scaling benefit was significantly affected by age. It implies that scaling should be added to the coverage list of the national health insurance in every age group since there is an increase in periodontal diseases with age. Concerning awareness of dental health insurance policy, the better-educated respondents took a better view of this system as they showed a more positive interest in its policies and shifts. Conclusions: It is desirable to provide more precise information as to eligible age, frequency and cost through public promotion of health coverage of scaling, and the effort to improve the health insurance coverage policy should be made in order to extend the scope of health coverage of scaling in the near future

    Abstract PDF
    Objectives: The purpose of this study is to investigate the effect of health behavior on oral health of Korean adolescents. Methods: The study subjects were 1,071 adolescents of 13-18 years old from Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012. Male students were 54.5% and female students were 45.5%. The study consisted of two groups: 13-15 years old and 16-18 years old groups. Data were analyzed by SAS 9.13 version. Results: Those who ingested alcohol had gingival bleeding in 41.0% and 31.0% in those who did not. Those who did not have regular oral examinations had 38.5% of gingival bleeding while those with regular oral examination had 29.7% of gingival bleeding (p<0.01). Students between 16 to 18 years old without oral care products tended to have more gingival bleeding than those who use auxiliary oral hygiene devices (OR=2.658, 95% CI=1.327-5.324).

    Nam.y.o | 이화정 | 최미혜 | 2016, 16(4) | pp.635~641 | number of Cited : 0
    Abstract PDF
    Objectives: The purpose of this study is to assess the characteristics of tooth surface after using Gracy curet and Ultrasonic scaler Methods: In this study, 12 teeth extracted were used. 12 specimens were divided into three groups with the same numbers, which were classified into Control group, Gracy curet use group, and Ultrasonic scaler use group, and after performing instrument operation, we measured the roughness and the loss degree of tooth surface by using SEM. Results: In groups using Gracy curet and Ultrasonic scaler, the roughness and the loss of tooth surface increased significantly(p<0.05). In the roughness of groups using Gracy curet and Ultrasonic scaler, Ultrasonic scaler group was higher in crown, but Gracy curet group was higher in root. As a result of observation through SEM, the roughness and the loss degree increased in order of Control group, Ultrasonic scaler use group, and Gracy curet use group. Conclusions: Taken together above results, both hand instrument and ultrasound equipment create roughness and loss in crown and in root, and hand instruments makes rougher than ultrasonic instruments in root, so it is thought to require thorough and accurate technical application not to damage tooth surface when removing plaque.

    Abstract PDF
    Objectives: The purpose of the study was to investigate the relationship between professor trust and learning flow in allied health students and to provide the basic data for the improvement of curriculum and teaching method. Methods: A self-reported questionnaire was filled out by 263 allied health students. The questionnaire consisted of 27 questions of professor trust by Likert 5 scale and 29 questions of learning flow by Likert 6 scale. Cronbach’s alpha in this study was 0.97 in professor trust, 0.96 in learning flow. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, correlation and stepwise multiple regressions. Results: The score was 3.72 in professor trust and 3.46 in learning flow. There were positive correlations between learning flow and professor trust including intimacy, professional, teaching skills and leadership. Stepwise multiple regression analysis revealed that learning flow was related with professor trust. Conclusions: The learning flow depends on professor trust. Based on the research, improvement directions that put strong emphasis on low section of professor trust and learning flow must be placed.
