  • Objectives: This study aimed to evaluate the relationship between pit and fissure sealants of the molars, and caries prevalence and experience to assess the effect of sealants on caries prevention. Methods: Data from 16,119 people were extracted from the seventh Korean national health and nutrition examination survey, which was conducted from 2016 to 2018. Demographic, socioeconomic, oral health-related behavioral, and oral examination survey data were collected as independent variables. SAS statistics for complex samples and multiple logistic regression analysis (Windows ver. 9.4) was used for the statistical analyses. Results: Caries prevalence and experience were significantly associated with age, sex, daily toothbrushing frequency, interdental cleaning, and having molar sealant. Multiple logistic regression analysis revealed a significant association between having molar sealants and the caries prevalence and experience among participants under 30 years of age after adjusting socio-economic variables and toothbrushing-related factors. Conclusions: This study confirmed the effect of molar sealants on caries prevention in Korea. Our results support that the application of molar sealants in children, adolescents, and young individuals is effective in preventing caries.

  • Objectives: This study was conducted to assess dental health states of disabled people and analyze association between perception and awareness toward dental health and dental health status. Methods: The survey was performed from June 25 through October 30, 2004. A total of 548 disabled people participated in the study with details of 419 living in eight residential care centers located in Gyeongsangbuk-do and 129 children from a special school and two day-care centers. All subjects underwent oral examination and surveyed through a questionnaire. Parents of 129 children with disabilities were also surveyed through a separate questionnaire. Results: The dental caries experience rate was 82.1% of total 548 subjects. By age, those in their 20s experienced a high rate of dental caries with 87.5%. By educational level, those with a middle school education experienced a high dental caries rate with 91.8% (p<0.05). Of total subjects who experienced dental caries, 78.9% had experience in dental caries treatment. By age, those in their 10s showed a high rate of dental caries treatment with 87.4%(p<0.05). By educational level, those with a high school education showed a high rate of dental caries treatment with 87.7%(p<0.05). Those in residential care centers had a high rate of dental caries treatment with 82.1%, which is significantly higher than 68.8% of those who used day-care centers. A tooth extraction rate was 38.0% of total subjects. Those in their 40s had a higher rate of tooth extraction(p<0.01). Those in residental care centers had a significantly higher rate of extraction with 43.4%, compared with 20.2% of those in day-care centers. Of total subjects, 61.5% had plaque. A high rate of plaque formation was observed in those in their 40s(92.0%), those with a high school education(84.0%) and those with multiple disabilities(77.8%)(p<0.01). Among total subjects, 47.6% maintained healthy periodontal tissue. Those in their 40s and those with multiple disabilities had diseased periodontal tissue(p<0.01). Of 129 disabled children, 43.8% had plaque with parents who were not oral health-conscious while 18.6% had plaque with parents who were oral health-conscious, showing a significant difference(p<0.05) Conclusion: The results of the study suggest the need for educating parents with disabled children about oral health and strengthening programs for oral health for teachers working at special schools and day-care centers.

  • Dental caries is induced by organic acids produced by oral bacteria. In order to prevent dental caries, therefore, it is essential to maintain neutral pH in the oral cavity. Urea plays a major role in oral pH homeostasis. Urea is hydrolyzed by bacterial ureases to ammonia, causing a pH elevation. Streptococcus salivarius has been shown to be a major contribution to oral ureolysis. Synthesis of urease by S. salivarius appears to be constituitive, but can be greatly enhanced by low pH. It is, therefore, conceivable that ureolytic activity of S. salivarius from a carious lesion is greater than that of the bacterium from a healthy tooth. In the present study, urease activity of S. salivarius isolates from dental plaque of carious lesions was compared with that of the isolates from plaques of the teeth and the dorsum of the tongue; 45 S. salivarius strains were isofated from carious lesions(>C2) of 21 individuals with dental caries and 30 strains from 10 individuals without dental caries. The results were as follows: 1. All the 21 individuals with dental caries harbored ureolytic S. salivarius whereas 3 of 13 individuals without dental caries harbored non-ureolytic strains of S. salivarius. 2. All the 45 S. saliuarius isolates from carious lesions showed urease activity. In contrast, of 30 isolates from individuals without dental caries, 17 isolates(56.7%) did not demonstrate urease activity, or if any, very little(<5${\mu}mol$/min/mg). 3. Urease activity of the isolates from carious lesions was greater than that of the isolates from individuals without dental caries : the urease activity ranged from 42 to $381{\mu}mol$/min/mg and from 0 to $208{\mu}mol$/min/mg, respectively. 4. At acid pH(5.5), the isolates which showed intermediate urease activity at pH 7.0 demonstrated even higher activity whereas the isolate with no or lower urease activity did not show any significant difference in their activity. However, the isolates with the greatest urease activity from both individuals with and without dental caries, exhibited a rather much lower urease activity at pH 5.5. The overall results suggest that isolates may have their own urease activity but the isolates exposed to chronic acidic environment of the carious lesion might elevate urease activity of S. salivarius, which in turn, might influence on survival of S. salivarius itself and other bacteria, establishing a new oral bacterial ecosystem.

  • 이 연구의 목적은 건강보험심사평가원의 자료를 이용하여 만 14세 이하 소아청소년들의 치아 우식 유병률의 경향성과 치료의 현황을 파악하는 것이다. 이 연구는 2011년부터 2020년까지 연도별로 전체 소아청소년이 포함된 모집단에서 약 100만명을 무작위 표본 추출한 집단의 진료내역을 이용하여 분석을 시행하였다. 이 연구에서 K02 치아우식 주상병명을 진단받는 아이들은 연도별로 증가하였고, 전반적으로 모든 연령군에서 치아 우식 치료를 받는 아이들도 증가하는 경향성을 보였다. 반면 중증의 치아 우식으로 인해 치수 치료 또는 발치를 경험한 10 - 14세 어린이들은 감소하는 경향을 보였다. 2021 - 2022년 아동 구강 건강 실태조사에서도 5세와 12세의 우식경험지수는 정체되거나 소폭 증가하는 경향을 보였으나 우식 유병자율은 감소하였다. 치료적 관점에서 개인적, 지역적 환경은 과거에 비해 전반적으로 개선된 것으로 나타났으나 예방적 관점에서 치아 우식 유병 상태와 예방 진료가 지난 10년간 개선되지 않고 정체 상태로 머물러 있던 것으로 해석된다. 따라서 대한민국에서 소아청소년을 대상으로 구강건강 증진 및 예방을 위해 시행되고 있는 구강 보건 사업에 대한 홍보와 효용성에 대한 평가가 필요하다.

  • Objectives: The aim of this study was to assess an association between nutrient intake and prevalence risk of deciduous dental caries among preschool children. Methods: A total of 922 children aged 3 to 5 years was selected from the database of Fourth Korean National Health and Nutrition Examination Survey(KNHAINS). Data were included socio-demographic characteristics, oral health related behaviour, nutrient intake(carbohydrate, protein, fat, calcium, phosphate, iron, sodium and potassium), and oral health status(dft index). To assess the crude and adjusted associations, logistic regression analysis were applied considering a complex sampling design. Results: Children who were more consumed protein, calcium, phosphate, iron and sodium had slightly lower prevalence risk of deciduous dental caries after adjusting for socio-demographic characteristics and oral health related behaviour. Moreover, prevalence risk of the highest intake of phosphate and sodium(3rd tertiles) was significant lower than that of the lowest intake(1st tertiles). Conclusion: The nutrient intake was slightly associated with the prevalence risk of deciduous dental caries.

  • Objectives: This study aims to evaluate the association between intake of energy, calcium and protein and permanent teeth caries in Korean children. Methods: Research data were obtained from the Fifth Korean National Health and Nutrition Examination Survey (KNHANES) and 1,274 Korean children within 9 to 12 years were selected as subjects for the study. The DMFT index, nutrition factors including total energy and protein intake, and degree of calcium intake were identified Chi-square test was performed to assess the difference of distribution in socioeconomic status, oral health behavior and nutrition factors according to sex. Multilevel linear regression analysis was performed to identify the relationship between DMFT index and the related variables. Results: Significant differences in energy, protein and Ca intake were confirmed according to the sex. Among 10 year-old children who intake total energy less than the recommended had few dental caries (p=0.058, ${\beta}=-0.411$). In addition, 11-year-old children having protein intake more than the recommended experienced dental caries (p=0.02, ${\beta}=0.588$). Conclusions: These results suggest that, there is significant differences between intake of energy and protein and dental caries among Korean children. However, further researches is needed to confirm between intake of energy and protein as a related factor.
