    정주희 | HieJin Noh | Yoo Jahea and 1other persons | 2017, 17(2) | pp.247~258 | number of Cited : 3
    Abstract PDF
    Objectives: This study was conducted to identify the correlation between belief in hand hygiene, activities and related hand hygiene performance rates among dental staff. Methods: This study was based on the evaluation of 329 dental practitioners, including dental hygienists who work at dental clinics, dental hospitals, general and university dental hospitals in Seoul, Gyeonggi-do Province, and Incheon. The questionnaire consisted of a total of 46 questions, including 7 questions on general characteristics, and 25 questions on hand hygiene beliefs, and 5 questions on hand hygiene activities, and 9 questions on hand hygiene practices. This study used 291 subjects for the final analysis, excluding subjects who had provided incomplete or inappropriate responses to the questionnaire. The collected data were analyzed using an independent t-test, ANOVA, x 2 test, correlation analysis, and multiple linear regression analysis, where p-values of <0.05 were considered statistically significant. Results: Longer clinical career was associated with a significant increase in behavior and norm beliefs, but no sequential difference in control beliefs. The hand hygiene performance was higher in staff at larger hospitals after contact with pollutants and contaminated environments. Higher age was associated with a significant increase in hand hygiene performance rates, but profession was not statistically significant in the performance rate of hand hygiene. The hand hygiene performance rate was ranked higher among those with average work hours per week of greater than 8 hours followed by those who worked fewer than 8 hours. Fewer work hours per week, a stronger belief in hand hygiene, less frequent exposure to contaminated environments, and a greater number of hand hygiene performance had a positive effect on higher hand hygiene performance rates. Conclusions: In order to increase the hand hygiene performance rate of dental practitioners, it is considered that required time for hand washing should be ensured sufficiently.

    Abstract PDF
    Objectives: The purpose of the study was to investigate the effect of calcium concentration in saliva on dental caries activity after consuming calcium. Methods: A total of 59 adult women aged 20 to 40 years were surveyed for calcium intake. The daily average calcium intake was analyzed through dietary records of the subjects. The subjects were divided into two groups based on daily average calcium intake. Salivary pH and concentrations of minerals in the saliva were obtained from A group and B group. Calcium (Ca 2+ ) and magnesium (Mg 2+ ) concentrations in saliva were measured by HPLC-Ion chromatography using 15 mM sulfuric acid. The dental caries activity test was quantified by salivary buffer capacity test and plaque pH test. Results: The mean Ca 2+ concentrations of A group was 12.75 μg/m, the mean Ca 2+ concentrations in the B group was 16.30 μg/mL (p<0.05) and respectively, Mg 2+ concentrations were found to be 0.48 μg/mL and 0.51 μg/mL. Calcium intake and calcium concentration in saliva showed a significant correlation (r=0.380). Conclusions: The mean Ca 2+ concentrations in saliva was higher in the high calcium intake group. Therefore, calcium intake in saliva was correlated with dental caries.

    Yong-Duk Park | 오혜영 | Park bok ri and 3other persons | 2017, 17(2) | pp.319~330 | number of Cited : 2
    Abstract PDF
    Objectives: The purpose of this study was to compare SYBR Green qPCR, TaqMan, and bacterial selective medium cultures for accurate quantitative analysis of oral microorganisms. Methods: The SYBR Green method is widely used to analyze the total amount of oral microorganisms in oral saliva. However, in this study, MTR-PCR method based on TaqMan method was performed using newly developed primers and probes. In addition, it was designed to confirm the detection agreement of bacteria among bacteria detection method. Results: As a result of MRT-PCR and SYBR Green qPCR analysis, more than 40 times (0.9-362.9 times) bacterium was detected by MRT-PCR. In addition, more bacteria were detected in saliva in the order of MRT-PCR, SYBR Green qPCR, and bacterium culture, and the results of MRB-PCR and SYBR Green qPCR showed the highest agreement. The agreement between the three methods for detecting P. intermedia was similar between 71.4 and 88.6%, but the agreement between MRT-PCR and SYBR Green qPCR was 80% for S. mutans. Among them, the number of total bacteria, P. intermedia and S. mutans bacteria in saliva was higher than that of SYBR Green qPCR method, and bacterium culture method by MRT-PCR method. P. intermedia and S. mutans in saliva were detected by MRT-PCR and MRT-PCR in 88.6% of cases, followed by the SYBR Green qPCR method (80.0%). Conclusions: The SYBR Green qPCR method is the same molecular biology method, but it can not analyze the germs at the same time. Bacterial culturing takes a lot of time if there is no selective culture medium. Therefore, the MRT-PCR method using newly developed primers and probes is considered to be the best method.
