Objectives: The purpose of this study was to examine the correlation between oral malodor and related factors in visitors to preventive dentistry practice lab. Methods: The subjects were selected from 71 visitors to preventive dentistry practice lab in a department of dental hygiene. The subjects were from twenty to twenty nine years old and had no systemic diseases or symptoms. The questionnaire consisted of general characteristics, oral malodor concentration, oral health status, oral health behavior, and self-rated oral malodor. Results: The mean concentration of the oral cavity gas was 50.80. The score of 50.80 was a weak smell by the selected judgement criteria. The oral malodor prevalence rate accounted for 39.1 percent and a weak smell was detected in 40 points. Those having higher oral malodor concentration tended to have lower self-rated oral health status(p<0.05). Conclusions: The results can not be generalized to determine the cause of oral malodor, but self-rated oral health status can be linked to systemic disease control. More investigation should be taken in order to analyzed the correlation between oral malodor and systemic diseases.

Objectives: The purpose of this study is to analyze relationship between oral health status and subjective oral malodor awareness of public health students. Furthermore, this study aimed to recognize the importance of prevention and treatment of internal and external factors and to contribute to the correct oral health management behavior. Methods: The study subjects were 500 students from 5 health departments of 2 universities located in Jeollanamdo who participated in self-administered survey from September 1 to 15, 2014. For statistical analysis, SPSS 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to investigate the effects of general characteristics, health behavior, oral health behavior, and oral health status on subjective oral malodor awareness. Finally, to investigate the relationship between oral health status and subjective oral malodor awareness logistic regression analysis was performed. Results: Subjective oral malodor awareness was significantly higher in the group requiring dental care with the score of 1.63 (95% CI 1.00-2.65) compared to the group not requiring dental care. Subjective oral malodor awareness was significantly higher in the severe coated tongue group with the score of 5.31 (95% CI 1.45-19.40) and significantly higher in the moderate coated tongue group with the score of 2.56 (95% CI 1.61-4.08). Subjective oral malodor awareness was significantly higher in the often mouth breathing group with the score of 2.13 (95% CI 1.02-4.47) and significantly higher in the sometimes mouth breathing group with the score of 2.66 (95% CI 1.65-4.29). Conclusions: In order to prevent oral malodor, it is emphasized that regular dental checkups, proper brushing after the meal, and brushing of the tongue are necessary to remove the coated tongue. In addition, the use of supplementary oral care products is considered to be a meaningful oral health behavior.

Purpose: This study was performed to investigate a correlation among oral hygiene habits, dryness of mouth, and self-perceived oral malodor and therefore to find out self-care methods which could be a help to reduce oral malodor. Methods: A survey of 296 dental undergraduate students of School of Dentistry, Pusan National University, who wrote consents voluntarily and participated in this study, was conducted using a questionnaire consisting of 17 questions and analyzed to investigate a correlation among oral hygiene habits (frequency of tooth brushing, water gargling, and drinking water, etc.), dryness of mouth indicating the amount of salivary secretion, and self-perceived oral malodor. Results: There was no significant correlation between mechanical cleaning factors and self-perceived oral malodor. The factor showing a strong correlation with severe self-perceived oral malodor was dryness of mouth (p=0.000). Conclusions: There was no correlation between mechanical cleaning habits and self-perceived oral malodor. Participants who felt self-perceived oral malodor more tended to have rather good mechanical cleaning habits. The factor showing a strong correlation with severe self-perceived oral malodor was dryness of mouth. Therefore trying to increase salivary secretion is considered to be a help to reduce self-perceived halitosis.

The purpose of this study was to examine the awareness of people in general characteristics about oral malodor. The subjects in this study are 184 people who visited the clinical practice lab at J health college to get their teeth scaled. After conducting a survey from May 1 to June 3, 2008, we selected four different ares and then analyzed the answer sheets from 179 respondents including smoking/nonsmoking, scaling experience, toothbrushing frequency and the use of oral hygiene supplies. SPSS WIN 12.0 program was used to make a frequency analysis and cross analysis. The findings of the study are as follows: 1. Concerning an intention of treatment for oral malodor, 37.4% didn't intend to receive treatment even in case of having bad breath. 28.5% didn't yet have any definite idea about that, and 20.7% had no mind to do that at all. 10.6% had an intention to receive treatment, and 2.8% want to receive treatment. 2. As for how to cope with oral malodor in case of suffering from it, 47.5% chewed gums or ate candy. 25.1% scarcely care about that, and 15.6% covered their mouth whenever they spoke. 9.5% had little confidence about talking to others, and 2.2% found it difficult to build an amicable interpersonal relationship. 3. Concerning what to do about another person's oral malodor, 40.8% did nothing, and 19% talked to the person about that. 17.3% gave him or her chewing gum. Among their oral health characteristics, toothbrushing frequency made a significant difference to the way they responded to another person's oral malodor(p<.05). 4. As to subjective feelings about another person's oral malodor, 41.9% just found it bearable. 36.9% were a little displeased, and 9.5% never felt bad about another person's bad breath. 8.9% tried to avoid the person, and 2.8% advised him or her to chew gum. 5. Regarding an intention of participating in a oral malodor program, 46.9% had no idea about that. 31.3% intended to participate in the program, and 13.4% wanted to do that without fail. 6.1% had no mind for that, and 2.2% were never going to do that. Among characteristics of the user oral hygiene device made a significant difference whether to participating in the oral malodor program(p<.05).

구취발생과 흡연 및 음주, 구강건강행위와의 관련성을 분석하기 위하여 2006년 10월 1일에서 2007년 3월 30일까지 만 30세 이상부터 59세까지의 성인 144명을 대상으로 설문조사와 함께 Oral $Chroma^{(R)}$(CHM-1, ABILIT Corp., Japan)를 이용한 구취농도 검사를 시행하여 다음과 같은 결론을 얻었다. 1. Hydrogen sulfide($H_2S$)는 치면세마를 규칙적으로 시행하는 군이 가끔 하는 군보다 매우 낮은 농도를 나타냈다(p<0.01). hydrogen sulfide($H_2S$) 농도와 관련성이 높은 요인으로는 치과 방문목적, 음주량, 음주 중 흡연량, 흡연기간, 현재 흡연량 등의 순으로 나타났다. 2. Methyl mercaptan($CH_3SH$)은 과거흡연군이 비흡연군과 흡연군보다 높은 농도를 나타냈고(p<0.05), 20년이상 흡연한 군이 20년 미만 군보다 높았으며(p<0.05), 음주 중 10개비 이상 흡연 군이 10개비 미만 흡연 군 보다 높은 농도를 나타냈다(p<0.05). 음주 특성에서는 주 5회 이상 음주 군이 주 1-2회 이하 음주 군들에 비해 높은 농도를 나타냈고(p<0.01), 잠자기 전 잇솔질을 하지 않는 군이 잇솔질을 하는 군보다 농도가 높았으며(p<0.05), 가끔 스켈링을 하는 군이 규칙적으로 스켈링을 하는 군보다 높은 농도를 나타냈다(p<0.05). methyl mercaptan($CH_3SH$) 농도와 관련도가 높은 요인으로는 치면세마 경험과 음주 중 흡연량으로 나타났다. 3. Dimethyl sulfide($(CH_3)_2S$)는 소주 2병 이상 군이 소주 1/2병 이하 군과 소주 1병 정도 군보다 높은 농도를 나타냈다(p<0.01). 이 결과 구취감소를 위한 교육에 있어서 잠자기 전 잇솔질 실천과 규칙적인 치면세마의 필요성은 강조되어야하며, 금연 및 절주에 대한 지도를 포함해야 할 것으로 사료되었다.
