Dental plaque has been considered as one of the major causes of inflammation. Therefore, removal of dental plaque by tooth brushing is the most important to prevent gingival and periodontal diseases and to maintain postoperative gingival health. The author executed clinical examination on 100 outpatients who were admitted to infirmary of dental college, S.N.U. The patients were examined on their tooth brushing method, frequency, habit and admitted experience to dental clinic. The obtained results were as follows; 1. The patient group who brushed with the method of Stillman, showed the lowest plaque index. 2. The examined group who brushed more frequently per a day, showed the tendency of reduced plaque index. 3. Plaque index was lowest in the group who brushed after meals and before bed. 4. The patient group who visited more frequently to dental clinic, showed the lower tendency of plague index. 5. Among the total examined group, those who recognized the importance of oral hygiene were less than 10%.

Adenoid cystic carcinoma arising from the submucosal glands of the trachea and bronchial tree is rare. The histopathology and natural history of bronchial adenoid cystic carcinoma have been well documented, but detailed descriptions of its cytomorphology are few. We report a case of primary bronchial adenoid cystic carcinoma in a 20-year-old female, diagnosed by bronchial brushing cytology. The cytologic specimens showed large clusters of small cells arranged around cystlike spaces containing globular basophilic material.

A case of primary malignant fibrous histiocytoma(MFH) of the lung occurring in a 62-year-old man is presented. After preoperative bronchial blushing and washing cytologic diagnosis of poorly differentiated carcinoma, surgical resection and lymph nodes dissection were performed. Subsequent histologic examination revealed a primary MFH. The diagnosis was confirmed by electron microscopic and immunohistochemical examinations. The review of the bronchial brushing and washing cytologic features disclosed many bipolar and a few unipolar spindle tumor cells with a "comel" configuration, mainly single cells, but also forming loose clusters. The nuclei were elongated and hyperchromatic and contained one or more irregular nucleoli. Scattered bizarre, multinucleated tumor giant cells were also present.

The purpose of the pilot study was to know the relationship between halitosis and oral hygine, to examine the difference of the positon of the straw to be placed in the oral cavity by using Halimeter. Fourteen persons that has good health condition without halitosis were participated in this pilot study. They were treated twice prophylaxis and then they had not tooth brushing during two weeks. After two weeks, they were examied to gingival index, plaque index, VSC valuses. The obtained results were as follosws : 1. No significant difference of VSC values were observed during two weeks withoiut tooth brushing. But significant difference of gingival index, plaque index were observed. It was suggested that halitosis was not caused by only plaque, complex reasons(salivary function, stress etc) maybe caused halitosis. 2. Here were significant reduction of VSC values as the depth of plastic straw into the oral cavity decreased (p<0.05)

Objectives : Periodontal disease is a serious oral disease that frequently occurs among adults. The objective of this study is to provide necessary data for the development of an oral health care program that can effectively manage periodontal disease and subsequently maintain and enhance oral health. Methods : Data was collected from patients of a dental clinic in Daejeon, Korea from 1 July to 25 August 2009. A thesis submitted to the Committee of Graduate School of Public Health & Biotechnology Chungnam National University in partial fulfillment of the requirements for the degree of Master of Public Health conferred in February, 2010. Results : 68% of the patients were aware of periodontal disease, with older patients exhibiting better awareness. 48.0% replied that their periodontal health is good in general, with older patients inclined to say that their periodontal health was poor. 70.5% cited bad brushing habit or skipping the act of tooth brushing as the cause of periodontal disease, while 63.5% reported brushing their teeth an average of 3 times a day. 56.5% said that they brush their teeth correctly, and 63.5% told that they brush their teeth up and down, and left to right and 70.0% replied that they would attend an educational program for the prevention of periodontal disease, with older patients shown to more likely attend such a program. Conclusion : a program that can motivate people to become aware of the importance of oral health care should be developed and implemented. Such a program should include the dissemination of correct and accurate oral health care information and measures for educating people about the importance of prevention.

Purpose : This study was conducted to improve cognitive oral healthcare care by analyzing the correlation between oral health behavior and oral health status Korean adolescents. The subjects were 65,528 youths in 798 schools monitored in the Twelfth Korea Youth Risk Behavior Web-based Survey in 2016. Methods : The general characteristics consisted of 9 items including sex, grade, and academic performance. The academic performance and economic status were restructured into "upper, middle, lower". Subjective health perception and subjective oral health perception were reorganized as "health", "normal", "no health". The sub-areas of oral health behavior include five times of daily brushing during the day yesterday. The number of brushing times was "0", "1-2", "3", "more than 4" After lunch at school, brushing was restructured as "always," "sometimes," "not." The oral health status subscale consisted of 6 items including tooth breakage and toothache at the time of eating. Result : Tooth fracture(43.7 %), pain in mastication(43.7 %), tooth tingling(47.4 %), gum pain and bleeding(45 %), pain in buccal mucosa(43.8 %) and halitosis(46.6 %) were rare in adolescent having healthy oral health status cognitively(P<.001). Nosymptom adolescents without dental sealant showed low tooth fracture(0.64 times), pain in mastication(0.67 times), tooth tingling(0.59 times), gum pain and bleeding(0.84 times), pain in buccal mucosa(0.76 times), and halitosis(0.90 times). Nosymptom adolescents without scaling showed low tooth fracture(0.88 times), pain in mastication(1.03 times), tooth tingling(0.82 times), gum pain and bleeding(0.64 times), pain in buccal mucosa(0.70 times) and halitosis(0.82 times). Conclusion : This study revealed that oral health status is correlated with oral health behavior. Development of educational media and program, and aggressive promotion required to establish oral health Korean adolescent.
