  • The author made a periodontal survey on 2,000 Korean adolescents in Seoul special city and Kyoungki-Do, to detect periodontal conditions and treatment needs. The obtained results were as follows: 1. 1.20% of adolescents had healthy periodontal tissues. 2. 11.95% showed only the gingival bleeding on probing, 66.55% had the calculus. 3. The proportions of adolescents with pocket depths about 4 to 5mm and over 6mm were 19.95% and 0.35% respectively. 4. Periodontal treatment need proportion showed 98.80% in oral hygiene instruction and 86.65% in oral prophylaxis; mean number of sextants affected was 2.96. 5. 0.35% was needed complex periodontal treatment. 6. In the sex and regional distribution, girls were slightly higher than boys in periodontal treatment needs and seoul than Kyoungki-Do; but the difference was not significant statistically.(p<0.05) 7. In the age distribution, periodontal treatment needs did not increase evidently with age; but comparing those for 15 years old with 19, the latter was slightly higher than the former.(p<0.05)

  • 본 연구는 치주질환 주요 병인균주 중의 하나인 Porphyromonas gingivalis의 세균내독소가 마우스 대식 세포주인 RAW264.7 세포에서의 nitric oxide의 생성과 iNOS의 발현에 미치는 영향을 분석하고 그 기전을 규명하기 위해 수행되었다. Butanol추출법과 phenol-water법에 의해 P. gingivalis 381로부터 세균내독소를 추출하였으며, NO의 생성은 배양 상층액 내의 nitrite 농도를 측정하여 결정하였다. 또한, iNOS의 western blot 분석과 reverse transcription (RT)-PCR 산물의 분석을 수행하였다. P. gingivalis의 세균내독소는 부가적인 자극이 없는 상태에서도 iNOS의 발현과 NO 생성을 유발하였으며, NF- ${\kappa}B$, microtubule polymerization, protein tyrosine kinase, 그리고 protein kinase C 등이 P. gingivalis 세균내독소에 의한 NO 생성에 간여하는 것으로 여겨진다. 또한, P. gingivalis 세균내독소에 의한 NO 생성에는 L-arginine이 요구되었다. P. gingivalis 세균내독소에 의한 NO 생성은 염증성 치주질환의 발병과 진행에 있어 중요한 역할을 하는 것으로 여겨진다.

  • 그람 음성균의 감염에 의한 만성 염증질환인 치주염이 동맥경화를 동반한 허혈성 심장질환 (협심증이나 심근 경색)을 일으킬 수 있는 위험인자로 작용할 수 있다는 보고가 있었다. 그러나, 그 기전에 관해서는 명확하게 알려져 있지 않다. 작용기전의 하나로서, 치주염에 의해 치주조직에서 국소적으로 생긴 염증성 싸이토카인(IL-1${\beta}$, IL-6, $PGE_2$, TNF-${\alpha}$)이 혈행을 따라 이동하여 심혈관에서 동맥경화를 일으킬 수 있다는 가설이 제시되고 있는데, 이 가설을 검증해 보고자 한다. 서울대학교 병원 순환기 내과에 불안정 협심증이나 심근경색으로 입원한 환자 및 과거 이 질환의 병력을 갖고 있거나 검진 목적으로 내원하여 관상동맥 조형술을 받은 환자들 중 동맥경화로 진단받은 사람을 실험군(24명)으로 하고, 동맥경화로 진단받지 않은 사람을 대조군(12명)으로 하였다. 치주질환의 활성도를 나타내는 치은 지수, 치태 지수, 치주낭 깊이, 부착 상실을 측정하였다. Paper strip을 실험대상 치아(Ramfjord's teeth)들 중에서 가장 깊은 치주낭을 가진 두 개의 치아를 택하여 각 치아의 가장 깊은 치주낭에 30초간 삽입한 후 밀폐된 plastic tube에 넣고 ELISA kit를 이용하여 IL-1${\beta}$, IL-6, TNF-${\alpha}$, $PGE_2$의 농도를 측정하였다. 환자의 plasma에서도 동일한 싸이토카인의 농도를 측정하였다. 설문조사를 통해 동맥경화의 위험 인자로 간주되어온 고혈압, 당뇨, 가족력, 심근경색이나 협심증의 기왕력, 흡연의 유무를 기록하였다. 혈액검사를 하여 total cholesterol, triglycerides, LDL cholesterol, HDL cholesterol, WBC, CRP (C-reactive protein)의 농도를 측정하였다. 치주조직에 대한 임상 검사 결과 치은의 염증상태를 나타나는 지표인 치은 지수에서만 실험군이 대조군에 비해 유의할 정도 (p=0.0174)로 높게 나타났고, 만성적인 염증의 결과로 인한 치조골의 사실 정도를 나타내는 치주낭 깊이나 부착 상실에서는 유의할 만한 차이를 보이지 않았다. 치주낭에서 측정한 염증성 싸이토카인 중 IL-1${\beta}$, $PGE_2$가 실험군에서 유의할 만한 차이 (p=0.005, 0.022)를 보이며, 더 높은 농도로 나타났고, TNF-${\alpha}$는 대조군에서 유의성 있게 (p=0.009) 높게 나타났다. 그러나, plasma의 싸이토카인이나, serum lipid/lipoprotein, C-reactive Protein, WBC는 유의할 만한 차이를 보이지 않았다. 또한 치은열구액내의 싸이토카인과 이에 상흥하는 싸이토카인 간에 상관관계는 관찰되지 않았다. 다변량 로지스틱 회귀분석 결과, 치은열구액내의 IL-1${\beta}$와 TNF-${\alpha}$ 만이 동맥경화와 유의성 있는 관련성을 보였고, 특히 IL-1${\beta}$와 교차비는 273으로 상당한 관련성을 보여주었다. 결론적으로, 치주조직에서 국소적으로 생긴 염증성 싸이토카인이 그대로 혈행으로 이동하여 혈장내의 싸이토카인 농도를 높이는 것은 아니다. 그러나, 치주염으로 인해 치은열구내액내에 국소적으로 증가된 염증성 싸이토카인은 동맥경화와 상당한 관련성을 가진다.

  • Patients who lost molars from dental caries or periodontitis have difficulty in maintaining their vertical dimension because their incisors and premolars also show vertical tooth movement. Missing posterior molars leads to occlusal interference and collapse of occlusal plane due to extrusion of opposite teeth and tipping of adjacent teeth. When this condition persists over long time, mandible moves forward, so it causes mobility and labioversion of upper incisors. This progress cannot be stopped spontaneously and the situation gets worse and worse. Therefore, for a patient with pathologic teeth migration caused by chronic periodontitis, interdisciplinary approach which is including periodontal treatment, orthodontic teeth alignment and prosthetic restoration of missing molars is required. This case report shows successful multidisciplinary approach to a patient who lost vertical dimension due to severe dental caries and periodontitis.

  • The purpose of this study was to investigate factors affecting perceived oral health status according to socioeconomic status and community periodontal index(CPI) and decayed, missing, and filled teeth(DMFT) using the 6th Korean national health and nutritional examination survey(KNHANES VI) and provide a basic data for plan of policy. The higher the age, the lower the household income and education level, the worse the subjective oral health had better oral health and there was a tendency that the respondents who had no oral exam within 1 year and experienced CPI or DMFT estimated their own health as worse. It is needed to make policy development to resolve the inequality of oral health.

  • The successful results of the treatment using a double crown denture have been reported in several papers for some of the few remaining teeth in patient. In particular, double crown dentures may be an alternative to treatment in cases where the periodontal status is poor and clasp type removable partial dentures are inappropriate (crown/root ratio > 1). In this case, the patient visited clinic with a chief complaint of difficulty in mastication due to loss of posterior teeth and overall teeth mobility. After teeth with severe periodontitis were extracted, treatment plan of mandible is Kennedy class I removable partial denture (RPD) and treatment plan of maxilla is hybrid telescopic double crown RPD with a friction pin. Patient is well adapted after the prosthetic treatment and we report due to achieving satisfactory results in pronunciation, mastication, retention and aesthetics.

  • Tooth impaction may lead to malocclusion, root resolution, cyst or aberrant changes in adjacent teeth. Clinical and radiographic examinations are used to locate the impaction, and appropriate treatment plans must be made to relocate the impacted tooth. When surgically exposing the impacted tooth, periodontal considerations to conserve maximum amount of soft and hard tissue are used. Oral hygiene instructions are emphasized to maintain sound periodontal health. Securing enough space for the impacted tooth and proper anchorage is important. Proper use of force and mechanics is crucial to prevent such complications as root resolution. Various patterns of orthodontic traction may be employed as situation permits. Most impaction cases can be managed with orthodontic traction to restore function and esthetics, provided that early detection and proper diagnosis and treatment planning are made.

  • This study aimed to examine whether needs for scaling are associated with health behaviors in a representative sample of middle-aged Korean people. We examined 5120 individuals aged 40 to 64 years who participated in the Seventh Korea National Health and Nutrition Examination Survey. Multivariate logistic regression analysis was performed with adjustments for demographic variables and health status. This analysis revealed significant associations between needs for scaling and the following: current smoking, no visits to dental clinics, current drinking, non-oral checkups, and non-use of oral care products. As a result of a subgroup analysis, significant factors differed according to gender. As a result of this study, needs for scaling were associated with identified health behaviors and findings about health behaviors that are effective for maintaining and promoting periodontal health in middle-aged people were confirmed.

  • The purpose of this study to grasp the effects of the stress coping method on the periodontal disease in order to provide raw data for the studies on the development of the training for effective stress copying method resulting in improvement in prevention, occurrence, and progression of periodontal disease. Data were collected from total of 326 subjects in their forties and fifties, during the period from March to October 2011. Using questionnaire and examination of periodontal health, and were analyzed using frequency, t-test, multivariate analysis of variance, multiple regression by SPSS ver. 19.0 (IBM Co., USA). The higher emotion-focused stress coping ($\beta$=0.341), the higher the gingival index, the higher the emotion-focused stress coping ($\beta$=0.239) the deeper the pocket depth, the higher the emotion-focused stress coping ($\beta$=0.158) the higher clinical attachment loss, showed statistically significant positive association. This study suggests that the dental clinic institute needs to implement education program including stress management and coping method improvement in order to prevent periodontal disease and make the occurrence and progression to be managed by professionals.
