Dental caries is one of the most common chronic diseases in the world, which are caused by complex actions of oral such factors as the bacteria, food, tooth, saliva and other factors. Although this is one of the typical oral diseases, we can acquire a high prophylactic effect by use of proper prophylactic measures and management. At the beginning of the 1940s, fluorine was first introduced to prevent dental caries which now is widely used. The fluorine application effects are varied from different concentrations and categories of fluorine, and different application method and frequency, etc. There is great debate on the best application method at the present. Dental clinics use iontophoresis as the application method and use it clinically. It uses APF (1.23%, Acidulated phosphate fluoride, APF) and uses 2% NaF so as to encourage more absorption of fluorine. Recently, fluoride varnish, which uses admixture mucus of colophony resin into 5% NaF, and a variety of forms that can be applied in the oral cavity are still being continuously researched. When using fluoride topical application on the enamel surface, it was highly recommended that fluoride varnish be used directly after fluoride iontophoresis rather than fluoride iontophoresis only or fluoride varnish by itself. The new method is more effective and does not need repeated application.

김용숙,조자원 대한예방치과학회 2011 International Journal of Clinical Preventive Denti Vol.7 No.4

Objective: Volatile sulfur compound as the most important oral malodor gas can be detected by a B&B checker unit in clinical. The standard value for B&B level should be needed in order to classify the normal range or abnormal, in each age group. Methods: Six hundred ninety six persons of Korean people, distributed with such age groups as children, adolescent, young adult, prime of the manhood and senile, in 4 regions in Korea, after calibrating the inter and intra machinery difference of B&B value (BBV). Mean and standard deviation of each age and gender group was calculated in order to suggest the B&B value for Koreans. Questionnaire for oral malodor was also distributed to subjects, in order to check the cause or severity of the malodor for Koreans. Results: Oral malodor was the severe complaint in senile group and the most in before breakfast. The average of halitosis level measured by B&B checker was 40.5±22.6 BBV, in oral gas, 37.5±23.6 BBV in breath gas and 33.9±18.4 BBV in nasal gas. Co-relation Co-efficient was revealed as r=0.396 (p<0.001) between in oral gas and breath gas, r=0.393 (p<0.001) between in oral gas and nasal gas, r=0.903 (p<0.001) between in breath gas and nasal gas, and r=0.279 (p<0.001) between in tongue plague and oral gas. Conclusion: It was recommended that the malodor control should be mainly focused in senile group for highly recognition and in young adult group for highly value measured.

서동훈,조자원,장연수 대한예방치과학회 2010 International Journal of Clinical Preventive Denti Vol.6 No.4

Objectives: In order to develop a model for a prevention oriented dental care system, periodontal disease prediction through an individual oral health index should be developed. Methods: We examined 200 patients who agreed to take the examinations among the patients who visited L dental clinic in Gongju from September 2009 to December 2009 in order to obtain data on 8 factors related to the periodontal health and the sum of CPI on 6 oral sections (standard of periodontal health), and processed recessional analysis between the 8 factors and the sum of CPI of various age groups. Results: The plaque index, gingival crevicular fluid and oral microorganism index reflect the periodontal status of adolescent effectively. The tooth mobility, status of alveolar bone and gingival crevicular fluid reflect the periodontal status of young adults effectively. The tooth mobility, plaque index and dental calculus index reflect the periodontal status of adults effectively. The status of alveolar bone and tooth mobility reflect the periodontal status of elderly effectively. Conclusion: The results described above suggest that the Prevention-oriented Incremental Dental Care System should be recommended in consideration of relative importance of factors related to periodontal health for each age group.

이명구,조자원,박진영 대한예방치과학회 2013 International Journal of Clinical Preventive Denti Vol.9 No.2

Objective: We attempted to measure the quantities and activeness of oral microorganisms using a phase-contrast microscope and conduct a oral bacteriological test based on germiculture to identify correlations between two different outcomes. Methods: A total of 50 adult patients, who have visited Preventive Dentistry of Dankook Dental Hospital between March and June 2012 and agreed to participate in the test without any other dental problems, underwent oral microorganism tests using a phase-contrast microscope and germiculture based on Dentocult SM and Dentocult LB to examine the correlation between two corresponding outcomes. Results: The correlation between the quantity of Streptococcus Mutans and the phase-contrast microscope was measured at r=0.292 (p<0.05) using Dentocult SM test method, suggesting that the two variables are weakly correlated with each other. The correlation between the quantity of Lactobacillus and the phase-contrast microscope was measured at r=0.311 (p<0.05) using Dentocult LB test method, suggesting that the two variables are weakly correlated with each other. Conclusion: Although the bacteriological examination using phase-contrast microscopes was found to be relatively less effective in forecasting dental caries, phase-contrast microscopes are recommendable as they help establish plans to prevent and treat dental diseases and examine prognosis through demonstrating active germs directly to patients so as to motivate them and maximize effects of dental health education.
