This study aimed to suggest the optimum number of rinsing by researching changes in optical density and pH in accordance with the number of rinsing after toothbrushing, and then verifying the amount of residual toothpaste in mouth. Total 14 university students who had healthy body with no difficulties in daily life were selected from the students of K university in Daegu as the research subjects. The research subjects rinsed their mouths with 40ml of water from zero time to 12 times after toothbrushing. After collecting each rinsing water, the optical density and pH were measured. In the results of measuring the optical density value of each rinsing water, the rinsing water of six-seven times or more after toothbrushing showed the constant value of optical density, which was statistically significant(p<0.05). There were no differences in accordance with the amount of toothpaste such as 1g, 1.5g, and 2g. Based on such results of this study, it would be necessary to provide the education of the use of dentifrice, and also to have diverse researches on the effects of residual dentifrice in mouth on the oral cavity.

The purpose of this study is to confirm the effect of natural tooth whitening using fruits that can be easily accessed in real life by increasing interest in tooth whitening in modern society. Twenty premolar teeth were divided into five groups (n=4). Strawberry (A), lemon (B), banana skin (C), baking soda (D) and whitening toothpaste (E) were treated with a toothbrush on the enamel surface. The tooth surface was treated with a toothbrush at the same time for 3 minutes for breakfast, lunch, and dinner, then washed with sterile distilled water, and stored in saline solution. This procedure was repeated for 4 weeks, and the color change of teeth was observed at intervals of one week. After 4 weeks, there was a significant difference in tooth color change after 3 weeks(p<0.05). Among them, strawberry and lemon showed higer effects to whitening toothpaste. It is believed that strawberries and lemons have a higher whitening effect than whitening toothpaste. Whitening toothpaste may be replaced with a safe natural whitening effect using strawberries and lemons instead of chemical ingredients that may be harmful to human body.

This study aimed to compare the elimination effect of dental plaque between general toothbrushes and chewing toothbrushes, so as to investigate whether the chewing toothbrushes have the practicality as the alternatives of general toothbrushes and their utilities in the real life. The study subjects were 30 healthy adults in their 20s who maintained the good dental condition over 16 teeth without systemic diseases, and the decline rates of dental plaque index after usages of general and chewing toothbrushes were calculated. Upon the comparisons of dental plaque decline rates before and after the usages of general and chewing toothbrushes, PHI index was declined from 7.02 to 1.91 in case of the general toothbrush demonstrating dental plaque decline by 72.79%, while it was declined from 6.72 to 4.08 in the chewing toothbrush demonstrating decline by 39.29%. Currently, a variety of dental care items are available in the Korean market, hence, various studies are required on the dental care items so as for the people to properly choose the items.

Background: This study involved a geriatric oral care expert who developed the competencies of students in the Department of Dental Hygiene and conducted preliminary research to develop an effective curriculum. Methods: A questionnaire was conducted in the last week of class targeting students who took courses in geriatric dentistry, geriatric dental hygiene, and practice. In order to confirm the educational effect according to the differences in the geriatric dental hygiene curriculum, the differences in students' achievement of major competencies, awareness of the geriatric dental hygiene process, class satisfaction, and ageism were analyzed. Results: Regarding major competency attainment, 'communication competency' was significantly higher in PBL education that combined theory and practice than that theory-oriented PBL education (p=0.038). For ageism, the tendency to avoid older adults was low in PBL education, which combined theory and practice, and was statistically significant (p=0.040). For class satisfaction, the rate of responding 'very high' for the 'class atmosphere' was significantly high (p=0.025) for PBL education that combined theory and practice. Conclusion: The PBL teaching method can be useful as a geriatric dental hygiene curriculum. However, it would be more effective to create a curriculum so that education in geriatric dental hygiene care practice can be combined with theory rather than a theoretical education alone.

The purpose of this study is to investigate the effects of incremental oral health care perceptions and experiences on oral health care performance by analyzing the results of incremental oral health care management for adults. As age increased, incremental oral health care experience is significantly higher. The results have shown that as age increases, interest in incremental oral health care becomes even higher. And, the group using secondary oral care products has significantly higher incremental oral care experience(p<0.05). Also, those who visit dental clinic regularly continue to experience incremental oral health care(p<0.05). In addition, the group that had experienced preventive dental services continued to be significantly highly relevant to oral health care(p<0.05). Based on the results of this study, it is possible to analyze the experience and influence of incremental oral health management and it can be used as basic data for the construction of incremental oral health care program in dental clinic.
