Objectives: The purpose of the study is to investigate the relationship between saliva factors and oral hygiene factors in adults. Methods: The subjects were 112 adults from April 1 to June 15, 2014. The selected salivary factors included stimulated/unstimulated salivary flow rates, salivary buffering capacity and pH, and the selected oral hygiene factors included halitosis, wet weight of tongue plaque and oral humidity in dorsum and inferior surface of tongue. Results: There were significant differences in stimulated/unstimulated salivary flow rates, oral malodor and wet weight of tongue plaque. There were significant differences according to age in stimulated/unstimulated salivary flow rates, salivary buffering capacity and wet weight of tongue plaque. Age had a negative correlation with salivary buffering capacity and had a positive correlation with wet weight of tongue plaque. Unstimulated salivary flow rate had a positive correlation with stimulated salivary flow rate, and stimulated salivary flow rate was positively correlated with oral humidity of inferior surface of tongue, salivary buffering capacity and halitosis. Oral humidity of inferior surface of tongue had a positive correlation with salivary buffering rate, pH and halitosis. Salivary buffering capacity was positively correlated with pH, and pH was negatively correlated with halitosis. Conclusions: The salivary factors were linked to the oral hygiene. As there may be great changes in salivary flow rate and oral hygiene due to various factors, the salivary factors seem to be one of the major factors to ensure oral hygiene and to promote oral health.

In this study, a survey was conducted to check the health status and health-related behavior according to the subjective oral malodor of some university students targeting 1,490 students who are attending N university in Cheonan. Based on the result to confirm the awareness of oral malodor and systemic diseases status, there were many cases to be realized such as sinus infection, chronic rhinitis, asthma, gastrointestinal disorders and xerostama among the people who think that they have bad breath, not the people who think that they don't have bad breath (p<.05). Based on the result to confirm the subjective oral health condition according to awareness of oral malodor status, it was shown that there were more respondents who have some oral conditions such as 'there are tooth to be treated', 'there is food stuck between tooth' and 'the gums are often swollen' among the people who realize that they have bad breath, not the people who think that they don't have bad breath (p<.05). It was shown that there were more cases to be brushed teeth everyday among the people who realize that they don't have bad breath than the people who think that they have bad breath (p<.05) and there were more cases to be used dental floss and to be brushed tongue everyday among the people who think that they don't have bad breath (p<.01).

Objective : The aim of this study was to investigate the ability of Cheonggugamrosu. a gargling agent made from herb extracts, to decrease oral malodor in vitro and in clinical research. Methods : For in vitro experiment. samples were Garglin (over-the-counter mouthwash), CheonggugamrosuA and Cheonggugamrosu B. Deodorizing activity of each sample against methyl mercaptan were analyzed by gas chromatography (GC). In clinical examination. subjects were 73 students from the oriental medicine school of Kyunghee University. The concentration of VSC in oral cavity of each subject was measured by Halimeter and subjects were divided into 3 groups that would gargle for 30 seconds with normal saline. Garglin and CheonggugamrosuA. Subsequently, concentration of VSC was measured in same way immediately, 2 hours and 4 hours after gargling. Results : During in vitro experiment by GC, deodorizing activities were 46.77% with Garglin, 80.64% with Cheonggugamrosu A and 82.28% with Cheonggugamrosu B. In clinical examination, at 2 hours after gargling, the concentration of VSC in the Cheonggugamrosu A group was significantly lower than in the normal saline group, but not in the Garglin group. 4 hours after gargling, the concentration of VSC in both CheonggugamrosuA and Garglin wasn't significantly different from the one in the normal saline group. Conclusions : Cheonggugamrosuhad better and longer deodorizing effect than Garglin in this study. Because of the safety of herbal medicine and its efficaciousness, we can use Cheonggugamrosu as a clinical prescription.

To maintain good oral hygiene, plaque control is essential and the most common and effective method is appropriate brushing. However accurate brushing is so difficult for children that the importance of brush is getting higher. We investigated the effect of tooth brushing instruction in plaque control for 40 children who came to Kyunghee university dental hospital, department of pediatric dentistry. We examined basic information by self-assessment, evaluated plaque index, tooth & tongue cleanness, malodor index for 4 times and compared values before and after tooth brushing instruction. Plaque index decreased(p<0.01) and tooth & tongue cleanness increased(p<0.01). There were no significant differences in mal-odor index. In conclusion, tooth brushing instruction is effective in removing dental plaque and its beneficial role is highly expected in establishing children's good oral hygiene.

Objectives : To obtain necessary fundamental data for the development of oral health improvement programs for senior citizens in the manner of investigating the Status of their oral health. Methods : Data were collected from 346 senior citizens aged 65 years or older who had lived in Seoul and Gyeonggido province, Republic of Korea. This study was conducted for 3 months from April 2011 to June 2011. Excluding those obtained from 34 respondents who gave inadequate responses to given questions, the data from 312 respondents were analyzed. Results : 1. The number of senior citizens who chose 'Sometimes' to as an answer to the question about the self-perception of their own oral conditions such as mastication, swallowing, gingiva hemorrhage, dry mouth, and/or oral malodor was the largest. As an answer to the question about the presence of interpersonal avoidance, 'No' accounted for the largest proportion. The number of respondents choosing gingiva treatment regarding the perception of the necessity for medical interventions was the largest. 2. In regard to the knowledge of oral health care, the percentage of correct answers was the highest for 'I brush my tooth before each meal' ($0.69{\pm}0.156$), while the lowest percentage of correct answers was seen for 'Gingival diseases can be improved by medications' ($0.33{\pm}0.472$). Conclusions : Based upon the above mentioned results, the author conclude that developing relevant national programs and support policies at a national level as well as implementing proactive and systematic home-visiting oral health programs at the levels of local autonomous entities or communities will lead to significant improvements in senior citizens' oral health and QoL (quality of life).
