윤현서(Yoon, Hyun-Seo) 한국산학기술학회 2014 한국산학기술학회논문지 Vol.15 No.9

보육교사들의 구강보건지식수준과 치아우식증 예방인식도를 조사하기 위하여 서울·경기, 부산·경남지역의 보육교사 를 대상으로 2013년 3월부터 5개월간 총 433명을 조사하였다. 보육교사들의 구강보건지식습득 경로는 병원56.6%로 가장 많 았고, 구강보건지식 응답 분포에서 정답률은 “치아가 빠졌을 때 우유에 넣어서 치과에 간다” 100%로 가장 높았고, “치아가 빠졌을 때 물로 씻는다” 35.1%로 가장 낮았다. 구강보건지식 수준은 부산·경남(p<0.001), 원생 수는 많을수록(p<0.001), 교사 의 연령이 젊을수록(p<0.001), 학력은 전문대졸업(p=0.002)에서 지식수준이 높았다. 치아우식증 예방효과 인식수준에서는 연 령이 증가할수록(p<0.001), 기혼(p=0.002), 직책에서는 원감(p=0.023), 경력에서는 10년 이상(p=0.009)에서 높았다. 아동들의 구강건강의 향상을 위해서는 보육교사들의 정확한 구강보건지식이 습득이 선행되어야 하며, 이를 위해서는 연령에 맞는 교 육프로그램을 개발하고 정기적교육이 이루어져야 할 것이다. This study examined the oral health knowledge of childcare teachers and their awareness of the prevention effects against dental caries. The subjects in this study were 433 childcare teachers in Seoul, Gyeonggi Province, Busan and South Gyeongsang Province, on whom a survey was conducted for five months, beginning in March, 2013. Hospitals (56.6%) were the most common route by which the childcare teachers acquired oral health knowledge. Regarding the distribution of the correct answers on oral health knowledge, every teacher gave the correct answer to the item "When a tooth comes out, it should be kept in milk and then be brought to a dental clinic," and the smallest number of them (35.1%) gave the correct answer to the item "When a tooth comes out, it should be washed with water." Concerning the level of oral health knowledge, the respondents, who worked in Busan and South Gyeongsang Province (p<0.001), who worked in childcare centers with more children (p<0.001), who were younger (p<0.001), and who were junior college graduates (p=0.002) had better oral health knowledge. In regard to the awareness of the prevention effects against dental caries, the respondents who were older (p<0.001) and who were married (p=0.002) were more aware of the prevention effects. According to position and career, teachers who were assistant principals (p=0.023) and had worked for 10 years or more (p=0.009) were more aware of the effects. Therefore, child care teachers should acquire accurate knowledge to improve the oral health of children, and regular training programs for age and education are needed.

윤현서(Hyun-Seo Yoon),김혜진(Hye Jin Kim),박충무(Chung-Mu Park) 한국구강보건과학회 2020 한국구강보건과학회지 Vol.8 No.4

Objectives: Many seaweeds are considered important natural resources since their abundant bioactive compounds. The present study tried to analyze the anti-inflammatory activity of several seaweeds in the human gingival fibroblast (HGF)-1 cells. Methods: Lipopolysaccharide from Porphyromonas gingivalis (LPS-PG), one of the main causes in the progression of periodontal inflammation, was applied to induce inflammatory response in HGF-1 cells. Nitric oxide (NO) was used as one of the hallmarks for inflammation, which was analyzed by the Griess reaction. The protein expression level of inducible NO synthase (iNOS) was identified by the Western blot analysis. Results: Inhibitory effect of NO production was investigated in the ethanol extracts of Asparagopsis taxiformis Trevisan de Saint-Léon (ATEE), Distromium decumbens (Okamura) Levring (DDEE), Galaxaura fastigiata (GFEE), Hypnea japonica Tanaka (HJEE), Myelophycus simplex (Harvey) Papenfuss (MSEE), and Scytosiphon canaliculatus (Setchell & N.L. Gardner) Kogame (SCEE) in LPS-PG stimulated HGF-1 cells. As a result, ATEE and HJEE the most potently inhibited while GFEE and SCEE slightly ameliorated NO production without any cytotoxicity. But, DDEE and MSEE did not exhibit the extraordinary NO inhibitory effect in LPS-PG induced HGF-1 cells. Western blot analysis was also conducted to identify the inhibitory effect of both extracts, ATEE and HJEE that sharply attenuated NO production, in LPS-PG induced HGF-1 cells. ATEE and HJEE mitigated iNOS expression in a dose dependent manner, which was in accordance with the result of NO production. Conclusions: ATEE and HJEE in the algal extracts used in this study drastically reduced the LPS-PG-induced inflammatory response in HGF-1 cells. All of this ATEE and HJEE will be used as candidate substances for treatment and prevention of periodontal disease.

윤현서(Hyun-Seo Yoon),채유정(You-Jung Chae) 한국산학기술학회 2017 한국산학기술학회논문지 Vol.18 No.8

본 연구는 2014년도 질병관리본부에서 실시하는 지역사회건강조사 자료를 이용하여 경상남도 지역주민 17810명을 대상으로 구강검진 여부와 건강관리행태의 관련성을 분석하였다. 통계 프로그램은 SPSS ver. 23.0을 사용하였다. 일반적 특성에서 구강검진 경험은 남자, 30-49세, 시 지역 거주, 대졸 이상, 가구소득 월 600 이상, 경제활동을 하는 경우 높았다. 구강건강관리에서 구강검진 경험은 스켈링을 하고, 점심 식 후 칫솔질, 취침 전 칫솔질, 4회 이상 칫솔질을 하는 경우 높았다. 생활습관에서 구강검진 경험은 음주를 하는 경우, 만성질환 유무에서 고혈압, 당뇨병, 뇌졸중, 심근경색증 및 협심증의 만성질환에 노출되지 않은 경우 구강검진 경험이 높았다. 주관적 건강인식(3.28점)과 주관적 구강건강인식(2.87점)은 구강검진 경험이 있는 경우 높았다(p<0.001). 따라서 구강검진 여부가 주관적 건강인식수준과 생활습관이나 만성질환과 관련이 있어 현재 구강검진 수진율을 향상하기 위한 방안을 마련하여야 하며, 정기적인 구강검진에 대한 인식도를 증진하기 위한 교육프로그램의 개발 또한 필요할 것으로 사료된다. The purpose of this study was to investigate the relationship between the dental screening and health care behaviors for 17810 residents of Gyeongsangnam-do province using the data of the community health survey conducted in 2014. The SPSS ver. 23.0 statistical program was used. The residents were male, aged 30-49 years, city dwellers, their final education level was college or higher, their income was more than 600 KRW monthly, and they had a lot of experience of dental screening. In terms of oral health care, scaling, brushing after eating, brushing before going to bed, and brushing more than 4 times a day were found in the dental screening. In terms of health care, the levels of drinking, without chronic diseases, self-rated health and self-rated oral health were high when the residents had experience of dental screening(p<0.001). Therefore, it is necessary to establish a plan to improve the oral examination rate, because the level of dental screening is related to the levels of subjective health awareness and chronic diseases and lifestyle, and it is necessary to develop an education program to improve the awareness of the need for regular dental screening.

부정교합 종류에 따른 교정치료의 인식과 구강건강영향지수(OHIP-14)

윤현서(Hyun-Seo Yoon) 한국산학기술학회 2017 한국산학기술학회논문지 Vol.18 No.12

본 연구는 부산지역 교정환자를 대상으로 부정교합의 종류와 교정치료에 대한 인식이 삶의 질에 미치는 영향을 파악하고, 부정교합의 종류에 따른 맞춤형 교육프로그램을 개발하여 삶의 질 향상의 기초자료로 삼고자 한다. 2015년 12월부터 약 6개월간 설문조사하여 최종 472부를 분석하였다. 연구결과는 부정교합의 가족력은 I급은 없음, II급, III급은 있음으로 응답하였고, 교육 실천은 자주실천에서 부정교합의 종류에 따른 차이를 보였다(p=0.003). 교정치료의 만족감에서는 불편감은 I급은 기간, II급과 III급은 통증(p=0.035)이였고, 통증부위에서는 치아가 가장 많았으나 II급에서 가장 높아 차이를 보였다(p<0.001). 교정치료 만족도에 따른 삶의 질에서는 현재 만족도가 높을수록, 자신감이 보통인 경우 삶의 질이 높았으며, 교정치료 시작 계기에서는 발음문제(p=0.013), 저작 불편감(p<0.001), 턱관절 소리(p<0.001)가 있는 경우 삶의 질이 낮았다. 구강 건강관련 삶의 질에 미치는 요인으로는 교정치료시기(p<0.001), 현재 만족감(p<0.001), 자신감 변화(p=0.003), 주관적 치아상태(p=0.008), 교합의 종류(p=0.019)순으로 영향을 미쳤다. 따라서 교정치료를 받는 환자들의 구강건강 상태를 면밀하게 분석하고 맞춤형 교정상담프로그램을 통하여 교정기간에도 삶의 질을 향상시킬 수 있어야 한다. The purpose of this study was to examine the influence of type of malocclusion and orthodontic treatment awareness on quality of life among orthodontic patients in the region of Busan as well as to develop an educational program tailored to the type of malocclusion as a way to improve quality of life. A survey was conducted for approximately 6 months from December, 2015, and the answer sheets from 472 respondents were analyzed. The most common painful area was the teeth, and this case was most predominant in the respondents with level 2 malocclusion, who differed from others in that regard (p<0.001). Regarding the relationship between satisfaction with orthodontic treatment and quality of life, respondents who were more satisfied currently and who were neither quite confident nor quite unconfident were ahead of their counterparts in quality of life. Concerning the reason for receiving orthodontic treatment, quality of life was lower among patients who started to receive treatment due to pronunciation problems (p=0.013), chewing difficulty (p<0.001), and temporomandibular joint click sound (p<0.001). With regard to influential factors on oral health-related quality of life, time for starting to receive orthodontic treatment was most influential (p<0.001), followed by current satisfaction (p<0.001), changes in confidence (p=0.003), self-rated teeth status (p=0.008), and type of occlusion (p=0.019). Therefore, accurate analysis of the oral health status of orthodontic patients and customized oral health education are required to improve quality of life even during the period of orthodontic treatment.

윤현서(Hyun-Seo Yoon) 한국콘텐츠학회 2014 한국콘텐츠학회논문지 Vol.14 No.8

본 연구는 주관적 치주건강인식 수와 진료내용(임플란트, 교정진료, 일반진료)에 따른 행복지수를 파악하고, 구강보건측면의 영향요인을 파악함으로써 구강보건관리 프로그램을 개발하여 행복지수를 향상시킬 수 있는 기초자료를 제공하고자 한다. 부산.경남지역에 위치한 치과병·의원에 내원한 환자를 대상으로 2013년 3월부터 약 7개월간 총 400명을 대상으로 실시하여 불성실한 응답 16명을 제외하고 최종적으로 384명을 대상으로 하여 진료내용에 따른 행복지수는 단일문항(p<0.001), 5문항(p=0.037) 모두 교정치료를 받는 경우 높았고, 임플란트 진료를 받는 경우 낮았다. 주관적 치주건강인식 수에 따른 행복지수는 단일문항, 5문항 행복지수 모두 구강증상이 없는 경우 높았고(p<0.001), 주관적 건강상태와 주관적 구강건강 상태에서 매우 건강하다고 인식할수록 행복지수가 높았다(p<0.001). 단일문항 행복지수에 영향요인은 소득이 많을수록(β= 0.198), 주관적 건강상태가 좋을수록(β=0.340) 행복지수가 높았으며, 당뇨질환이 있을수록(β=-0.103), 치주질환수가 많을수록(β=-0.204) 행복지수가 낮게 나타났다. 5문항 행복지수에 영향요인은 연령이 높을수록(β=0.241), 소득이 많을수록(β=0.198), 진료내용이 일반일 때(β=0.107), 주관적 건강상태가 좋을수록(β=0.275), 주관적 구강건강상태가 좋을수록(β=0.132) 행복지수가 높았으며, 치주질환수가 많을수록(β=-0.195) 행복지수가 낮았다. 병·의원에 내원한 환자를 대상으로 주관적 구강건강 인식을 향상하기 위한 구강건강프로그램이 마련되어야할 것이다. The purpose of this study was to examine the relationship of the self-rated peridontal health status of dental patients and the type of their treatment(implant, orthodontic treatment and general treatment) to the quality of life(happiness index), to investigate influential factors for oral health, and ultimately to provide some information on the development of oral health care programs geared toward boosting the happiness index. The subjects in this study were the patients who visited dental hospitals and clinics in Busan and South Gyeongsang Province. As for relationship between the field of treatment and the happiness index, the patients who received orthodontic treatment scored higher in both each itemand all the five items, and the patients who received implant treatment scored lower. Regarding links between self-rated periodontal health status and the happiness index, the patients who had no oral symptoms scored higher in both each item and all the five items, and the respondents whose self-rated health status and self-rated oral health status were both very good scored higher in the happiness index. The preparation of oral health programs that aim to improve the self-rated oral health of patients who visit dental hospitals or clinics is required.

해조류를 함유하는 천연세치제의 치아미백효과 임상시험 연구

윤현서(Hyun-Seo Yoon), 박충무(Chung-Mu Park) 한국구강보건과학회 2020 한국구강보건과학회지 Vol.8 No.3

Objectives: To verify the tooth whitening effect of toothpaste containing seaweed and establish a basis for the development of functional toothpaste that whitens teeth using natural extracts. Methods: Clinical trials were conducted with the participation of 70 volunteers. There was a negative control group (general toothpaste), positive control group (commercially available whitening toothpaste), and test groups A and B. They were examined before and 6 weeks and 12 weeks after their use of VITA Easyshade V for transposition to assess their tooth color and BB Checke to assess them for halitosis. Moreover, with the use of Dentobuff strips, their pH and stimulated saliva were measured; each measurement was conducted three times, and the average value was recorded. Results: The findings verified that the tooth whitening effect of the toothpaste containing algae was similar to, if not slightly better than, that of a commercially available whitening toothpaste. In addition, the toothpaste containing seaweed reduced all halitosis, and saliva outflow became more effective as the seaweed content concentration increased. Conclusions: The effects of natural extracts on tooth whitening have been gradually demonstrated, but when used in products such as toothpaste, the effects are unlikely to appear immediately; it takes about 6 months for the effects to show. Therefore, clinical trials should be advanced, and the number of representatives should be increased. Nevertheless, the demand for tooth whitening is increasing, and it is sensible to whiten teeth using natural extracts to form a basis for developing functional toothpaste that will alleviate bad breath.

부산지역 65세 이상 노인의 구강건강상태에 따른 구강건강 관련 삶의 질(OHIP-14)

윤현서 ( Hyun Seo Yoon ) 한국치위생학회 2013 한국치위생학회지 Vol.13 No.5

Objectives: The purpose of this study was to investigate the relationship between the oral health status of elderly people and their oral health-related quality of life. Methods: The subjects were the elderly people over 65 years old in Busan. A total of 479 elderly people participated in the study from general hospital, two research institutes, eight dental clinics, six welfare institutions, sixteen senior centers, and three nursing homes. The oral health impact profile-14 (OHIP-14) was used in the routine dental checkups of the elderly people. Results: Those who had no oral symptoms had a better oral health-related quality of life. Among the subfactors of the OHIP-14, significant differences were shown in functional limitation(p=0.001), physical pain(p<0.001), emotional discomfort(p<0.001), physical disability(p=0.001), emotional disability (p=0.001), social disability(p=0.005), physical handicap(p=0.003) and total OHIP-14(p<0.001). Those who had 18 sound teeth(natural teeth) or more had a better oral health-related quality of life. Among the subfactors of the OHIP-14, significant differences were shown in functional limitation(p<0.001), physical pain(p=0.007), emotional discomfort(p=0.019), physical disability(p=0.018), Emotional disability(p=.032) and total OHIP-14 (p=0.006). Conclusions: The results revealed a close relationship between oral health status and oral health-related quality of life. The number of sound teeth(natural teeth) and frequency of toothbrushing had a more positive influence. Therefore oral health programs for the elderly people can preserve remaining teeth. Toothbrushing is the best way to improve the quality of life in the elderly people.

윤현서(Hyun-Seo Yoon) 한국콘텐츠학회 2013 한국콘텐츠학회논문지 Vol.13 No.11

본 연구는 경북지역 294명의 근로자들을 대상으로 행복지수에 구강건강 행위와, 주관적 구강건강인식의 영향을 파악하여 이를 바탕으로 산업장 근로자들을 위한 구강보건계획을 수립하는 기초자료로 활용하고자 하였다. 구강건강 행위에 따른 행복지수를 살펴보면 1년 내 정기검진여부에서는 정기검진을 받는 경우 단일문항 행복지수(p=0.002), 5문항 행복지수(0.012)에서 모두 높게 나타났고, 1년 내 스켈링을 받은 경우 단일문항 행복지수(p<0.001), 5문항 행복지수(p=0.003)모두 높게 나타났다. 칫솔질 횟수에서는 칫솔질 횟수가 많은 경우 단일문항 행복지수(p<0.001), 5문항 행복지수(p=0.023)으로 높았으며, 구강보건교육을 받은 경험이 있는 경우 단일문항 행복지수(p=0.041), 5문항 행복지수 모두에서 높게 나타났다. 근무지에 칫솔을 보관하는 경우에는 단일문항 행복지수(p=0.001), 5문항 행복지수(p<0.001) 모두에서 높게 나타났으며, 아플 때 즉시 치과방문이 가능한 경우 단일문항 행복지수(p<0.001), 5문항 행복지수(p<0.001)모두에서 높게 나타났다. 이상의 결과에서 산업장 근로자들의 행복지수를 높이기 위한 체계적인 구강건강프로그램이 마련되어야할 것이다. The purpose of this study was to examine the impact of the oral health behavior and self-rated oral health of workers on their happiness indexes in an attempt to provide information on oral health planning geared toward industrial workers. The subjects in this study were 294 workers in North Gyeongsang Province. As a result of analyzing the relationship between their health behavior and happiness indexes, the workers who got regular health checkups had higher happiness indexes for both single items(p=0.002) and entire five items(0.012), and those who had their teeth cleaned over the past year had higher happiness indexes for both single items(p<0.001) and entire five items(p=0.003). As for a toothbrushing frequency, the respondents who brushed their teeth more frequently had higher happiness indexes for both single items(p<0.001) and entire five items(p=0.023), and those who had ever received oral health education had higher happiness indexes for both single items(p=0.041) and entire five items. The workers who kept their toothbrushes at work had higher happiness indexes for both single items(p=0.001) and entire five items, and the respondents who could afford to visit a dental clinic immediately in case of having a toothache had higher happiness indexes for both single items(p<0.001) and entire five items(p<0.001). The findings of the study suggest that the preparation of systematic oral health programs is required to boost the happiness indexes of industrial workers.
