Objectives: The purpose of this study was to clarify the relationship between perceived oral health and oral health status, oral health symptoms in elementary school students. Methods: Oral examination and oral hygiene survey were performed on 446 students in 5th grade from 4 elementary schools in Wonju, Gangwon province. Oral examination assessed decayed teeth, filled teeth, missing teeth from decay. Then, oral hygiene status was evaluated by O'Leary index and self-reported questionnaires were surveyed. We analysed the collected data using SPSS program ver. 20.0, significant difference level was p<0.05. Results: 38.4% of the subjects rated their oral health as poor, 61.6% as good, female students was worried about their appearances than male students. Their decayed teeth was 1.01, missed teeth was 0.01, filled teeth was 1.75, O'Leary index was 64.49, oral hygiene status of them was poor. Perceived oral health was associated to decayed teeth, DMFT, oral health symptoms except tooth fracture and pain of mucosa (p<0.05). However, there is no correlation between perceived oral health and oral hygiene status (p>0.05) Conclusion: Self-rated oral health status of the elementary school students was related to decayed teeth and oral health symptoms, but it was not related to oral hygiene status. Therefore it was needed to improve the oral hygiene status in elementary students by devise effective way to motivate them.
Objectives : The purpose of this survey research was to investigate the relationship among oral health State, behavior and knowledge of oral health of patients who participate in dental hygiene students voluntarily. Methods : The subject in this were patients who got a scaling at the oral hygiene practice lab in the department of dental hygiene in S university dental clinic from April 1 to May 31, 2010. For the data analysis, an SPSS WIN 11.5 program was used and its signification level was 0.05. Results : 1. For the oral health state according to sex distinction, it showed the men's 0.78 MT index was higher than women's 0.48 MT index and statistically significant difference. For FT index, women(4.72) was higher than men(3.50) and it showed statistically significant difference(p<0.05). 2. For the oral health state according to age distinction, DT index of under 20years(2.44) was higher than the others and it showed statistically significant difference(p<0.05). 3. For the oral health state according to marriage distinction, not married DT index(1.59) was higher than married DT index(2.56) and it showed statistically significant difference(p<0.05). 4. For the oral health behavior according to age distinction, 87.0% 20~29years patients replied as I have experience of my teeth scaled and it showed statistically significant difference. 18.5% more than 30 years replied as I use interdental brush and it showed statistically significant difference. 18.5% more than 30 years replied as I use powered brush and it showed statistically significant difference(p<0.05). 5. For the oral health state according to oral health behavior distinction, there were significant difference that regular visit of dental clinic, experience of teeth scaled, toothbrushing, oral hygiene device(p<0.05). 6. For the oral health state according to oral health knowledge distinction, there were significant difference that toothbrushing time after each meal, appropriate toothbrushing time, toothbrushing method, dental caries foods(p<0.05). Conclusions : I suggest with the result of the study that there was a very close relationship between oral health status, behavior and knowledge of oral health. Therefore student of the dental hygiene should be encouraged to pay more attention to oral health care of the patient, and they should be well educated oral health care personnels who volunteers in practice for oral prophylaxis.
A comparative study on the effects of the water fluoridation program and fluoride mouth rinsing program in the elementary school children. This study was performed to compare the oral health status of permanent teeth for children of the caries prevention effects by using methods of fluoride 309 children for water fluoridated program, 240 for fluoride mouth rinsing program and 248 for control group. The DMFS rate, DMFT index, soft and hard deposite rate were analysed from the oral examination. And 300 questionares from the parents who lived in Cheong ju city were evaluated to see the situations of using the tap water. The results were as follows; 1. Caries experience rate in permanent dentition was the lowest in fluoride mouth rinsing group. 2. It was estimated that soft deposite rate was comparatively low in the fluoride mouth rinsing group but calculus deposite rate was no significant difference in each other groups. 3. The 72.0 percentage of parents who lived in non fluoridated water area were misunderstood that they lived in water fluoridated area. 4. The 66.8 percentage of residents used the piped water as drinking water. 5. It was recommended that fluoride mouth rinsing program was suggested in rural area, on the other hands, toothbrusing program in urban area with water fluoridation to prevent the dental caries for school children.
Objectives : The aim of the study is to estimate the dental caries experience and the factors influencing the dental caries in children and adolescents and to provide the data for effective management of oral health in children and adolescents. Methods : Subjects were 446 students randomly recruited in primary, middle, high school students located in Seoul from April 1 to May 31 2011. The data were collected by a questionnaire survey and direct oral examination. The collected data were analyzed with the SPSS WIN 14.0 program. Results : DMF in male accounted for 88.8% and that in female accounted for 89.1%. The oral promotion behaviors in female was significantly higher than those in male (p<0.001). Aged (p<0.05) and well-educated parents(p<0.001) tended to have better oral promotion behaviors. The higher oral health knowledge, the better oral health promotion behaviors. Better oral health promotion behaviors tended to have lower DMFT and DT index (p<0.01). In regression analysis, age, oral health promotion behavior in children and adolescents were related to the dental caries experience (p<0.001). Poor oral health promotion behaviors increased the dental caries experience. Conclusions : The active oral health care can prevent dental caries in children and adolescents. The concern for oral health care is important to maintain healthy dental hygiene.
Using imprint cultures and epithelial smears, the density and prevalence of colonization of oral mucosal sites and denture surfaces by Candida albicans has been determined in 28 healthy dentate subjects and 20 denture wearers. With questionnaire, oral and denture examination, the relationship between the carrier rates and several factors; DMFT, oral hygiene index, salivary pH & denture plaque score were studied. But these factors have not significant relationship to the carrier rates. Imprint culture appears to be sensitive technique for detecting candidal carriers and be useful for distinguishing between the healthy carrier state and candidal infection. Cigarette smokers had a significantly increased carrier state (P<0.05) compared with nonsmoker in male dentate subjects. Female were more frequent carriers than male in dentate and denture group, but these differences were not significant. In denture wearers, there was a higher density and frequency of candidal colonization of all mucosal sites sampled, compared with that of healthy dentate group especially anterior palate and posterior palate showed highly significant differences in frequency of candidal colonization (P<0.05). The distribution of Candida albicans is not uniform throughout the mouth. The tongue in the healthy dentate subjects and the impression surfaces of upper dentures are the primary oral reservoirs for the fungus. Overnight wearing of dentures was associated with increased density and frequency of candidal colonization and density.
The author conducted a dental survey of a college girl students and compared with that of E college students 10 years ago which based on the same criteria. The items of this survey included the prevalence of dental caries, DMFT and the kinds of restored material. All college students 1,414 were examined in May 1978, with the recommended criteria and method of W.H.O.. Among them, the data of 1,393 were analyzed for this study. The following results were obtained: 1. The average number of present teeth were 28.97${\pm}$1.64. 2. The prevalence of dental caries was 84.92% and D.M.F. index was 15.51. Average D.M.F. teeth were 4.49${\pm}$3.69. 3. The average number of decayed (D) teeth were 2.09${\pm}$2.16. 4.30% of the present decayed teeth was secondary decay, and 2.44% of the decayed teeth was indicated for extraction. 4. The average number of missing(M) teeth were 0.32${\pm}$0.79. It included 8.56% of root fragements. 5. Average number of filled(F) teeth were 2.09${\pm}$3.17. F-ratio of this group was 46.45%. The analysis revealed 50.88% of amalgam alloy, 31.41% of gold inlays, and 1.20%, the least among the filling materials, silicate cement or composite resin. 6. While the prosthodontic treatment, such as crown and bridge has reduced than that of 10 years ago, the fillings and inlays as the conservative means has increased.
This study aims to identify the regional distribution in the prevalence of dental caries and related multidimensional factors among 12-year-old children in Korea. Data from the 2018 Child Oral Health Survey were used to calculate the average DMFT index of 12-year-old children in metropolitan cities, and a multi-level regression model was applied to explain the regional distribution of dental caries prevalence and related factors. Factors were divided into two levels by administrative structure. This study finds a significant regional difference in the prevalence of dental caries in 12-year-old Korean children across metropolitan cities. Multilevel analysis showed that district-level factors (average number of pit and fissure-sealed permanent teeth, dental treatment demand rate, preventive treatment rate, sex ratio, and number of dentists per 100,000 people) and metropolitan-level factors (intakes of cariogenic beverages and number of pediatric dental hospitals and clinics per 100,000 people) had a significant effect on dental caries prevalence (p < 0.05). Individual characteristics and local socio-environmental factors influence the prevalence of dental caries. Especially considering the strong dependence on preventive treatment and accessibility to dental care services, it is necessary to provide adequate preventive treatment and expand health care resources in high-risk areas of dental caries.
Objectives : The aim of the study is to propose the fundamental data for further developments of the school dental clinic program through evaluating comprehensive improvements of the indices and the oral health status. Methods : This studied was carried out from December 2010 to September 2012. Subjects were 239 elementary school 4th, 5th, 6th grade students having no school dental clinic and 195 elementary school 4th, 5th, 6th grade students having school dental clinic in Busan. They completed self-reported questionnaires after accepting informed consent. The questionnaire included knowledges, attitudes and practices for oral health recognition and supports of the school dental clinic program. Results : Permanent tooth caries prevention rate revealed 59.0%, 53.3%, and 62.0%. in 4th, 5th, and 6th respectively. Rate of Care Group with fissure sealant permanent teeth showed 80.3%, 88.0%, and 88.9% respectively. Index of Care Group with fissure sealant permanent teeth revealed 2.68, 2.90, and 3.97, respectively. DMFT index of Care Group was 1.11, 1.35, and 1.51, respectively. Active D rate of Care Group resulted in 16.7%, 24.1%, and 16.7%, respectively. Dental health education group showed high awareness level of fluoride and sealant effect for caries prevention. Tooth brushing of three times per day was more effective when using rolling tooth brushing. On the other hand, oral health recognition and oral status in the control group was low. Conclusions : Oral health recognition was closely related to good oral care. Expansion of oral health care business is important to prevent dental caries. Systematic approach for oral health education programs and human resources development is very important to improve oral health care.
Purpose: The aim of this study was to evaluate the effects of oral health care programs in 3 school-based oral health care center among primary schoolchildren. Methods: School-based oral health care programs included fluoride mouth rinsing, pit and fissure sealing for permanent premolars and molars, fluoride gel application and chewing of xylitol candy. All of the programs were carried out by one dental hygienist among 'D' primary schoolchildren in Daegu city under the supervision of a dentist. Baseline dental examinations were completed and preventive care was implemented for 544 children during one year. All of the children visited a school-based oral health care center every three months for a regular check-up. The final oral examination was conducted from March 15 to April 1, 2004. The data analysis data was made on the basis of SAS 8.01. Mean differences between 2003 and 2004 data were compared by paired t-test. Corresponding p-values were considered significant at values less than 0.05. Results: The DMF rate and DFT index were reduced to 8.0% and 8.4% during one year respectively, but there were no statistically significant differences. The DMF rate was significantly reduced (16.3%) after a one year program of school-based oral health care practice. The DMFT(Decay Missing Filling Tooth) index was also reduced compared to 2003 throughout the entire grade. Conclusion: School-based oral health care programs can reduce the prevalence of dental caries prevalence among schoolchildren during one year. This program also improved the oral health capacity of schoolchildren. It is recommend that the school-based oral health care program should be extended to every primary school in Korea.
Objectives: The aim of this study was to evaluate the oral health status and behavior in Korean diabetic adults. Methods: The study subjects were 11,840 adults who participated in the fifth Korea National Health and Nutrition Examination Survey(2010-2012). Diabetic status was defined by doctors and fasting blood sugar(FBS) level. Oral health status was assessed by decayed-missing-filled teeth(DMFT), community periodontal index(CPI), periodontal disease, denture needs, limitation of oral function, and chewing difficulty. The oral health behavior was evaluated by oral examination within a year, brushing times a day, and use of auxiliary oral product. The data were analyzed by descriptive analysis, chi-square tests and multiple logistic regression analyses. Results: The prevalence rate of diabetes mellitus diagnosed by doctor and FBS was 8.3% and 10.2%, respectively. The prevalence rate of periodontitis was 25.4%. The proportions of $DMFT{\geq}20$, $CPI{\geq}3$, periodontal disease, denture needs, oral function limitation and chewing difficulty in the confirmed diabetic group by doctor were significantly higher than those of the non-diabetic group(p<0.05). In multiple logistic regression analysis, the adjusted odds ratio(aOR) for periodontal disease(aOR=1.73, 95% CI=1.41-2.12), presence of denture needs(aOR=1.40, 95% CI=1.06-1.84), limited oral function(aOR=1.43, 95% CI=1.15-1.78) and chewing difficulty(aOR=1.41 95% CI=1.13-1.77) in diabetic subjects were significantly higher than those of the non-diabetic subjects. There were similar associations between diabetes defined with FBS and oral health. In oral health behavior, diabetic subjects had significantly lower odds ratios for oral examination(aOR=0.76, 95% CI=0.60-0.98), brushing time ${\geq}2$ times(aOR=0.73, 95% CI=0.57-0.93), and auxiliary oral products(aOR=0.74, 95% CI=0.59-0.94). Conclusions: There was a significant relationship between oral health status and behavior in Korean diabetic adults. Further study is needed to evaluate the underlying mechanisms between diabetes mellitus and oral health status.
