Methods : The subjects in this study were performed with 235 people, who were over 65 years and resided in Daejeon Province, from June 20 to July 10, 2011. An individual interview was held, and they got a dental checkup. As for data analysis, chi-square test, t-test, one-way ANOVA, pearson correlation were utilized. Results : The older age in the whole research subjects and the lower educational level led to the less remaining teeth and the larger missing teeth index. The decayed missing filled teeth index and the decayed missing filled teeth rate were higher in more women and older age and in the lower educational level. Tooth mortality rate was higher in the older age, the lower educational level, and the group of living together with spouse. The maxillary-mandibular fixed-bridge status in the mouth was indicated to be the highest in the full-denture mounting ratio as for elders in over 80 years old. Oral Health Impact Profile(OHIP-14) average score was $56.05{\pm}11.64$ in the whole research subjects The decayed missing filled teeth index and the decayed missing filled teeth rate showed significantly positive correlation with the decayed missing filled teeth rate, tooth mortality rate and showed significantly negative correlation with OHIP-14. Tooth mortality rate showed significantly negative correlation with OHIP-14 Oral Health Impact Profile(OHIP-14) showed significantly positive correlation with its factors. Conclusions : Accordingly, the policy effort is considered to be necessary that implements in elders in order to spend active senescence, and that elders' health and oral-health behavior can be implemented continuously and preventively through classification according to elders' physical function.

Background: Obesity and dental caries have common risk factors such as food intake, eating habits, and lifestyle. Nevertheless, there has been no consensus on the significant association between obesity and dental caries, and additional studies are needed. We investigated the relationship between obesity and dental caries in some college students in this pilot study. Methods: Forty-two obese college students (body mass index [BMI]≥25) registered at a University Obesity Clinic and 19 normal students (18.5≤BMI<25) were recruited. Oral examinations were conducted, and anthropometric data and blood samples were collected. The blood concentrations of low-density lipoprotein (LDL), high-density lipoprotein, and triglyceride were also measured. After controlling for dental plaque index, a univariate analysis of dental caries indicators related to obesity was performed; partial correlation analysis was also conducted. A nonparametric test was used for the analysis of gender-related trends due to the limited number of participants. Results: The obese group had significantly fewer missing teeth (p=0.014), missing surfaces (p=0.035), filled surfaces (p=0.038), and decayed-missing-filled surfaces (p=0.020) than the normal group. There was no difference between the males in the normal and obese groups. The females in the obese group had significantly fewer missing teeth (p=0.003), missing surfaces (p=0.003), and decayed-missing-filled surfaces (p=0.046). Partial correlation analysis showed a weak negative correlation (r=-0.256) between the blood LDL concentration and decayed-missing-filled teeth. The other obesity and dental caries indicators were not correlated. Conclusion:The blood cholesterol concentration had a negative relationship with dental caries, and there were fewer cases of dental caries in the obese group in this study. However, it is important to clarify the relationship between obesity and dental caries through a dietary survey or additional investigations considering other confounding factors.

삶의 질에 대한 관심이 증가함에 따라 건강과 관련된 삶의 질 향상에 대한 관심도 증가하고 있다. 구강건강의 관점에서도 구강질환이 삶의 질을 저하시키며, 구강질환의 예방이 삶의 질을 향상시킨다. 본 연구에서는 구강보건지식과 구강보건실천 정도, 구강건강상태, 그리고 구강건강 관련 삶의 질의 관계를 알아보고자 하였다. 부산지역에 소재한 종합병원 치과, 치과병원 및 치과의원에 내원한 환자 311명을 대상으로 2010년 3월 16일부터 한달간 구조화된 자기기입식 설문지를 사용하여 대상자의 일반적 특징 및 구강보건지식, 구강보건실천, 구강건강관련 삶의 질(OHIP-14) 등에 대한 자료를 수집하였으며, 치과의사 11명이 치경과 탐침으로 사랑니를 제외한 28개의 치아를 대상으로 우식경험치아수(DMF index)를 확인하였다. 분석결과, 구강보건지식은 구강보건실천에, 구강보건실천은 우식경험치아수와 구강건강관련 삶의 질에 직접적인 영향을 미치는 것으로 나타났고, 우식경험치아수도 구강건강관련 삶의 질에 유의한 변수임을 알 수 있었다. 그러나 구강보건지식은 우식경험치아수와 구강건강관련 삶의 질에 직접적인 영향요인이 아니라, 구강보건실천의 매개를 통해 간접적으로 영향을 미치는 것으로 나타났다. 이러한 연구결과는 구강건강관련 삶의 질을 높이기 위해서는 직접적인 효과를 가지고 있는 구강보건실천 수준과 우식경험영구치아수를 적절히 관리할 수 있도록 하는 방안마련이 절실히 요구됨을 말해주고 있다. 즉 우식경험치아수는 구강보건실천에 직접적으로 영향을 받는 변수이므로 단순히 구강건강관련 지식만을 전달하기보다는 태도의 변화와 실천 행동을 유도할 수 있는 구강보건교육 프로그램을 개발함으로써 구강질환의 예방과 조기치료로 이어지도록 해야 할 것이다.

Objectives : The objective of this study was to compare oral health behaviors and oral health indices between regular scaling group and irregular scaling group. Methods : This study was performed at M Dental Clinic in Busan on 352 dental patients treated between January 2014 and June 2015 using V6.0 software and medical interviews. The 352 patients were divided into 3 groups and oral health behavior (OHB) and oral health indices were compared. Results : The OHB scores significantly differed among Groups C and A. Group C had the lowest number of "Bad" scores for the Simplified Debris Index (S-DI), Simplified Calculus Index (S-CI), and Simplified Oral Hygiene Index (S-OHI). Groups B and A had the lowest number of "Excellent" scores. Group C had the lowest bleeding on probing (BOP), calculus rate (CR) and decayed teeth (DT). Furthermore, Group C had the highest number of missing teeth (MT) and filled teeth (FT). Conclusions : Patients who underwent regular scaling had the highest OHB and oral health index scores. This emphasizes the importance of regular scaling for prevention and early detection of oral disease.
