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 collected data was analyzed by using SPSS WIN 15.0 program. The following conclusions were obtained. 1. The result of actual condition of toothbrushing is as follows. As the answer of a question about whether or not toothbrushing after every meal at ordinary times, the largest was 47.5% of being average. The occasion of toothbrushing before going to bed at ordinary times was the largest with 47.5%. The daily toothbrushing frequency was 3 times mostly and the general toothbrushing method at ordinary times was a rolling method. The frequency of exchanging toothbrushes for the past 1 year was 3 times, which is the largest with 45.0%. 2. As a result of the actual condition of using oral care products, the majority of students don't use electric toothbrush, interdental brush, or mouth-rinse except dental floss. Accordingly, there need to be education and promotion with diverse methods so that a patient oneself can prevent oral disease by selecting and using oral care products that are proper for each individual. Also, it was indicated that there is no big difference in oral hygiene effects depending on the amount of toothpaste used. Thus, to avoid wasting toothpaste, we need to educate and promote to use the amount of toothpaste under 0.3g.
