Effect of Repeated Oral Health Education on the Oral Health of Preschool Children.

Journal of Dental Hygiene Science.2017;17(5):423-432. doi:10.17135/jdhs.2017.17.5.423

This study aimed to investigate the effect of repeated oral health education on the oral health of preschool children. This study classified the control group of children of 5~6 years of age where the oral health education was conducted one time, and the experiment group where the oral health education was conducted 4 times. The oral health conditions of each group and their risk of developing dental caries were also assessed. No significant difference was observed in the participants in terms of general characteristics, oral health conditions, risk of developing dental caries, and oral health behavior after oral health education. The two groups did not show a significant difference (p<0.001) in dental plaque index before and after oral health education, and showed a significant difference (p<0.001) according to the number of education sessions. Before oral health education, the participants in both groups were brushing their teeth incorrectly. However, after the third session, 56.7% of the participants in the experimental group and 9.4% in the control group used the correct method of tooth brushing. A significant difference was observed between the two groups (p<0.05). In addition, when the tooth-brushing time was compared, the two groups showed a significant difference (p<0.001), and a significant difference was observed in terms of the number of education sessions (p<0.05). In summary, repeated oral health education had significant influences on the dental plaque index, tooth-brushing method, brushing occlusal surfaces, and tooth-brushing time. Therefore, when oral health education is carried out, repeated oral health education in children is more effective than one-time oral health education as reflected in the changes in dental plaque index and oral health behavior. Moreover, oral health education is considered effective in changing the oral health behavior of children when conducted at least 3 times.

A Yeon JEONG ; Sun Jung SHIN ; Bo Mi SHIN ; Soo Myoung BAE

Journal of Dental Hygiene Science.2017;17(5):383-397. doi:10.17135/jdhs.2017.17.5.383

We attempted to develop a problem-based learning (PBL) module for integrated education in dental hygiene with the aim of helping students gain clinical competencies necessary for dental hygienist work. To develop the PBL Module for Clinical Dentistry in Dental Hygiene course, the researchers identified literature related to not only educational technology, but also medical science, nursing, dentistry, and dental hygiene. During the design phase of the PBL module, problem scenarios and a plan for the teaching and learning process were developed. Developing problem scenarios involved describing a problematic situation and three questions related with that situation. To cultivate competencies required in dental clinics, each question was related to the diagnosis of a dental disease, dental treatment, and dental hygiene procedures for care. Teaching-learning process plan included the designs of operating environment, operational strategies, learning resources, facilitation of problem-solving process, and evaluation. It is necessary to evaluate the PBL module for integrated education in dental hygiene to confirm its effectiveness.

Hyun Ok LEE ; Sun Mi KIM ; Ji Young PARK

Journal of Dental Hygiene Science.2017;17(5):398-404. doi:10.17135/jdhs.2017.17.5.398

The present study aimed to examine the influence of mental health factors on oral health factors using data from the Korean National Health and Nutrition Examination Survey (KNHANES). A total of 1,548 elderly individuals aged over 65 years who completed the screening and health questionnaire were selected as the final study participants. The psychological health factors related to perceived oral health status were depression and stress when the gender was controlled, and in terms of gender, both elderly male and female individuals were stressed and depressed. These results suggested that the psychological health of elderly individuals negatively affects not only perceived oral health but also the quality of life. In addition, the psychological health of the elderly individuals should be systematically managed along with oral health care and overall health care and lifestyle. If a comprehensive health management system is available for low-income groups or an elderly person living alone, it should positively affect and improve the quality of life of elderly individuals.

A Rong HEO ; In Suk PARK ; Kwui Sook SONG

Journal of Dental Hygiene Science.2016;16(1):45-52. doi:10.17135/jdhs.2016.16.1.45

The purpose of this study was to examine the impact of the self-perceived stress of high school students on their oral health care and the relationship between stress and oral health care. The subjects in this study were the students in four different high schools located in Chungcheongnam-do, on whom a self-administered survey was conducted. The answer sheets from 939 respondents were analyzed by PASW Statistics ver.18.0 for Windows. The girls were more stressed than the boys about their studies, appearance and material resource, and the sophomores felt more stress about their home and studies. The group whose academic achievement was good in the past semester had the lowest stress about home and material resource, and the group whose economic standard was higher were less stressed about appearance and material resource. As a result of comparing their oral health care by general characteristics, the groups who were sophomores and whose academic achievement was good in the past semester were most excellent in that regard, and the students whose economic standard was higher and whose average weekly allowances were larger took better care of their oral health. Concerning the influential factors for oral health care, stress about peer relationship was positively related, and stress about material resource was negatively related. Given the findings of the study, the development of oral health care programs that include how to relieve stress is required, and more intensive education is necessary as well. Besides, education for school personnel in charge of student health management and the development of related manuals are both required.

Kyeung Ae JANG ; Jung Hyun PARK

Journal of Dental Hygiene Science.2016;16(2):183-192. doi:10.17135/jdhs.2016.16.2.183

A total of 228 dental hygienists working in dental hospitals and clinics in the Busan and Gyeongnam areas were surveyed between August 1, 2015, and October 15, 2015. The factors influencing infection control awareness and implementation levels among the dental hygienists were investigated to prepare basic data with the goal of establishing guidelines for systemic infection control. Treatment preparation support for infection control positively correlated with equipment and facility support (r=0.4343, p<0.01), treatment skill and information support (r=0.231, p<0.01), infection control education support (r=0.266, p<0.01), infection control awareness (r=0.354, p<0.01), and infection control implementation levels (r=0.442, p<0.01). Equipment and facility support positively correlated with treatment skill and information support (r=0.418, p<0.01), infection control education support (r=0.422, p<0.01), infection control awareness (r=0.404, p<0.01), and infection control implementation levels (r=0.454, p<0.01). Infection control education support positively correlated with infection control awareness (r=0.348, p<0.01) and infection control implementation levels (r=0.405, p<0.01). Infection control awareness positively correlated with the infection control implementation level (r=0.879, p<0.01). The factors influencing the awareness of infection control include treatment preparation support, equipment and facility support, treatment skill and information support, and infection control education support. The influencing the infection control implementation level include treatment preparation support, equipment and facility support, infection control education support, and treatment skill and information support. To enhance the awareness of infection control and implementation levels amongdental hygienists, an infection control system must be established and implemented A rigorous system for evaluating dental clinics must also be established to ensure an ideal dental treatment environment and to protect patients' health and safety.

The purpose of this study was to evaluate the association between oral health-related quality of life and school life satisfaction in high school students. A questionnaire-based survey was conducted on high school students in Daegu, South Korea from November to December, 2015, and final data from 432 students was analyzed. Analysis of oral health-related quality of life in terms of general characteristics showed that both academic achievement and stress were significant factors (p<0.05). With respect to school life satisfaction, academic achievement was found to be a highly significant influencing factor (p<0.01). Correlation analyses of oral health-related quality of life with various factors of school life satisfaction showed positive correlations with personal relationships, educational learning environment, social support. Regression analysis of school life satisfaction showed that academic achievement and oral health-related quality of life were influencing factors. These results indicate that oral health-related quality of life may play a significant role in school life satisfaction.

Ji Won PARK ; Sung Suk BAE

Journal of Dental Hygiene Science.2016;16(2):150-156. doi:10.17135/jdhs.2016.16.2.150

In this study, the surface treatment of a self-cured temporary crown was polished using a denture bur, silicone bur, or pumice. The color stability of the temporary crown resin specimen was evaluated by immersing it in coffee, and cola, wine, beer, red pepper paste, or soybean paste. Two-hundred eighty-five identical resin specimens with six types of staining solution and three types of surface treatment were placed in a shaking incubator at 37℃. The degree of discoloration was observed using a time-lapse recording of days 1, 5, and 7. L*, a*, and b* were measured using a spectrophotometer, which shows the quantitative value of discoloration, and statistically processed after calculating ΔE*. The results show that as time passed, all the specimens showed a color change (p<0.001). The amount of color change was the greatest in in crowns with denture bur polishing on the day 1, 5, and 7. As the precipitation time increased, the ΔE* value was also increased. Of the specimens immersed on day 1, the greatest color change in crowns polished with denture bur was observed in those immersed in red pepper paste, while the smallest color change was observed in those immersed in cola. On days 5 and 7, the greatest color change in crowns polished with denture bur was observed in those immersed in red wine. Crowns polished with silicone bur and immersed in soybean paste exhibited the smallest color change. Based on the results, compared to pumice polishing, silicone bur polishing results in better color stability, saves time and money, and is recommended for patients with temporary crowns.

Young Ki KIM ; Ho Jang KWON

Journal of Dental Hygiene Science.2016;16(2):142-149. doi:10.17135/jdhs.2016.16.2.142

The number of male dental hygienists has been continuously increasing in dental services. The purpose of this study aimed to identify the relationship between job stress, job satisfaction, and turnover intention in male dental hygienists and to provide basic data to improve their job satisfaction. The study population was 110 Korean male dental hygienists working for dental clinics or hospitals. The data were collected from November 10 to December 7, 2015. After an explanation about the objective of the study, 110 questionnaires were distributed via email, and 97 responses were analyzed using SPSS. Overall averages of job stress, job satisfaction and turnover intention in male dental hygienists were 3.05, 2.92, and 3.47 out of 5, respectively. Some sub-factors of job stress, including interpersonal relationships at the workplace and future prospects of dental clinics, were proven to have statistically significant negative influence on job satisfaction (p<0.001). Regression analysis was performed with job stress and job satisfaction as independent variables and turnover intention as a dependent variable. Results showed that job stress had a positive effect on turnover intention (p<0.01) while job satisfaction had a negative effect on turnover intention (p<0.001). Job satisfaction was revealed to have statistically significant negative influence on turnover intention (p<0.001). Some of sub-factors of job stress, including work environment and future prospects of dental clinics and professional position, had a positive effect on turnover intention (p<0.05). The study showed that higher job stress led to higher turnover intention, and higher job satisfaction led to lower turnover intention. Accordingly, job stress and job satisfaction are critical factors for turnover intention in male dental hygienists.

Jae Hyun AHN ; Ji Hye KIM ; Ji Young KIM

Journal of Dental Hygiene Science.2016;16(2):176-182. doi:10.17135/jdhs.2016.16.2.176

The purpose of this study was to evaluate the in-vitro efficacy of the active ingredients of dentifrice following treatment time. The whitening effect was evaluated by a change in lightness value relative to the contact time of hydrogen peroxide, by using artificially stained hydroxyapatite discs. The anti-calculus effect was assessed based on the amount of calcium eluted from the human dental calculus by sodium pyrophosphate. Remineralization was evaluated by the Vickers hardness test following the application of sodium fluoride to bovine enamel. In order to view dentinal tubules occlusion, the formation of insoluble calcium salts by bovine dentin specimens was observed using scanning electron microscopy. Change in lightness value (ΔL) was 5.50±1.51 after 1 min of treatment, 5.73±0.43 after 3 min, 8.64±0.24 after 10 min, 18.93±0.76 after 30 min, and 27.35±0.54 after 60 min. The amount of calcium eluted from the human dental calculus was 4.23±0.14 ppm after 1 min of treatment, 4.51±0.04 ppm after 3 min, 12.12±0.16 ppm after 10 min, 17.85±0.81 ppm after 30 min, and 25.15±0.32 ppm after 60 min. The Vickers hardness change value (ΔVHN) was 1.96±1.44 after 1 min, 1.52±1.06 after 3 min, 9.06±0.15 after 10 min, 10.83±5.13 after 30 min, and 12.55±2.09 after 60 min. Partial dentinal tubules occlusion was observed at 10 min and complete occlusion was evident at 60 min. In summary, the use of patch type dentifrices for 10, 30, or 60 min were 1.57 to 8.26 times more effective than using the paste type dentifrices for 1 to 3 min. Based on these findings, it is reasonable to expect that the use of patch type dentifrices for 10 min would lead to remineralization, anti-calculus and dentinal tubules occlusion effects, and that use for 30 min would result in a whitening effect.

Sang Hwang OH ; Soo Jeong HWANG

Journal of Dental Hygiene Science.2016;16(2):165-175. doi:10.17135/jdhs.2016.16.2.165

Health behavior is one component of life style and is defined as behaviors performed by a person to protect, promote, or maintain the their health. General health behavior habits include not smoking, weight management, moderate drinking, regular exercise. The aim of this study was to analyze the relationship between toothbrushing and general health behaviors in 1,013 adults using data from the 2008 Daejeon Health Promotion Survey. Results showed no significant difference by region in general health behavior and toothbrushing. Smoking, alcohol consumption and toothbrushing frequency were related to sex, age, monthly income, occupation, and the degree of obesity. The predictoers of toothbrushing more than a day by losistic regression were female sex (vs. male, OR 1.88, 95% CI 1.20∼2.95), age ≥65 years (vs. twenties, OR 0.51, 95% CI 0.26∼0.99), monthly income 2 miillions Korean Won (KRW) to 3 millions KRW (vs. <2 million won, OR 1.58, 95% CI 1.04∼2.42), white collar (vs. self-employment, OR 2.74, 95% CI 1.62∼4.64), and regular exercise (vs. never, OR 1.60, 95% CI 1.21∼2.11). We recommend the independent administration of oral health promotion programs focusing on aged and vulnerable social group because general health behaviors except regular exercise were not related to toothbrushing frequency.
