  • Purpose: The purpose of this study was to evaluate severe periodontitis with tooth loss as a modifiable risk factor for Alzheimer dementia (AD), vascular dementia (VaD), and mixed dementia (MD) using the National Health Insurance Service-National Health Screening Retrospective Cohort database with long-term follow-up over 14 years. Methods: Multivariate Cox hazards regression analysis was applied to a longitudinal retrospective database, which was updated in 2018, to evaluate the association between severe periodontitis with few remaining teeth and dementia after adjusting for potential risk factors, including sociodemographic factors and comorbid diseases. Results: Among 514,866 individuals in South Korea, 237,940 (46.2%) participants satisfying the inclusion criteria were selected. A total of 10,115 age- and sex-matched participants with severe periodontitis and 10,115 periodontally healthy participants were randomly selected and evenly assigned. The results showed that the risks of AD (hazard ratio [HR], 1.08), VaD (HR, 1.24), and MD (HR, 1.16) were significantly higher in patients with severe periodontitis with 1-9 remaining teeth after adjustment for sociodemographic factors, anthropomorphic measurements, lifestyle factors, and comorbidities. Conclusions: Severe periodontitis with few remaining teeth (1-9) may be considered a modifiable risk factor for the development of AD, VaD, and MD in Korean adults.

  • Objectives: The objectives of this study were to investigate the distribution and level of periodontopathic bacteria with the general characteristics and oral health condition of the elderly. Methods: A total of 335 elderly individuals aged 65 years or older who lived in Ganghwa-gun, Incheon, were included in the study. Oral examination, investigation through a questionnaire, and collection of saliva were carried out. The collected saliva was analyzed for the distribution and levels of bacteria (red and orange complex bacteria) by real-time polymerase chain reaction. Statistical analyses were performed using chi-square test, t-test, one-way analysis of variance, and Pearson's correlation coefficient with SAS statistical software version 9.4. Results: Among the general characteristics, there were significant differences in the distribution of Porphyromonas gingivalis, Treponema denticola, and Parvimonas micra depending on sex, age, and dental visits (p<0.05). The number of remaining teeth and denture use were related to the distribution of periodontopathic bacteria, except T. denticola (p<0.05). Additionally, periodontitis was related to the distribution of P. gingivalis (p<0.05). As the number of remaining teeth increased, the copy number of red and orange complex bacteria also increased (p<0.05). Those individuals who did not use dentures and had periodontal disease had more periodontopathic bacteria (p<0.05). Conclusions: The distribution and copy number of periodontopathic bacteria in the elderly were more related to oral health condition than to general characteristics. In particular, the distribution and copy number of periodontopathic bacteria were higher in subjects with multiple remaining teeth, no dentures, and periodontal disease.

  • Objectives: This study aimed to validate the moderating effect of oral health on the relationship between perceived health status and health-related quality of life in the elderly and to use this information as primary data to suggest oral health policies for the aged society. Methods: This study included 3,707 subjects aged over 65 years who answered all the variables used in the study model and completed the health questionnaire and screening survey based on the sixth Korea National Health and Nutrition Examination Survey. Baron & Kenny's linear regression analysis using SPSS 22.0 and SPSS Macro Version 3.1 programs was performed to confirm the moderating effect of the number of remaining natural teeth, chewing difficulty, and cardiovascular disease on the relationship between perceived health status and healthrelated quality of life in the elderly. Results: The number of remaining natural teeth, chewing difficulties, and cardiovascular diseases affected the perceived health status of the elderly. As the number of remaining natural teeth increased, the effect of perceived health status on the quality of life in the elderly was buffered. The effect of perceived health status on the quality of life increased with chewing difficulties and the number of cardiovascular diseases. In particular, it was confirmed that chewing difficulties, rather than the number of cardiovascular diseases. had a greater effect on the quality of life in the elderly. Conclusions: Oral health policies and projects are required to ensure oral rehabilitation with dentures and implants and restore chewing function to improve the quality of life of the elderly in Korea.

  • 'Crossed occlusion' is the condition in which occlusal intercuspation is lost when several teeth on upper and lower jaw remain. This report describes a clinical case in which a patient had two upper-left posterior teeth and two lower-right posterior teeth; typically known as left-right crossed occlusion. Considering the patient's general condition and financial situation, the treatment plan included placement of two implants on each jaw against the remaining teeth using surgical guide. To find out the ideal position of implants, digital diagnostic wax-up was preceded by superimposing the cast and cone beam computed tomography image, which was aided with radiographic stents. The consequent surveyed implant bridge provided stable vertical stop for fabrication of the implant assisted removable partial dentures. The patient was satisfied with the functionality and esthetics of definitive prosthesis.

  • One of the primary advantage of acrylic resin teeth is their ability to bond chemically to the denture base resins. But, occasionally, failure have been observed in which acrylic resin teeth break lose from the denture, indicating that chemical bonding does not always occur. The most probable explanation for this type of failure was the presence of a trace of wax remaining as a residue on the surfaces of the teeth after the boiling-out procedure which adgered to the tooth surface and prevented bonding. The purpose of this stdy was preparing the specimens of denture base resin with acrylic resin teeth that four treatment method to ridge lap portion of the tooth and investigated bond between the teeth and denture base resin with tensile strength. Compared results of tensile strength on test specimens were as follows: 1. The mean of strength among the four test groups showed the difference was significant enough(P 0.01). The order of its strength mean was methylene chloride treatment group, detergent solution treatment group, kerosene-ether treatment grgoup, boiling water only group. 2. In compared results between the wax eliminating method groups, there were significant difference between the boiling water only group and other groups(P 0.01), no significant difference were found in the wax eliminating method groups except boiling water only group(P 0.05).

  • This study was peformed to investigate the distribution and magnitude of stress at supporting tissue of abutment teeth and residual ridge tissue with remaining unilateral posterior teeth. Four types of removable partial dentures that included clasp retained removable partial denture, attachment retained removable partial denture, telescopic removable partial denture, and swing-lock partial denture were designed, and strain gauge was used for stress analysis. Each prosthesis was subjected to simulated vertical and oblique load. The following conclusions were drawn from this study. 1. The clasp retained removable partial denture generally distributed simulated vertical force more evenly to the supporting structure. 2. The stress at buccal side of 1st premolar was the lowest in swing-lock partial denture and that was highest in attchment retained removable partial denture. The stress at lingual side of 1st premolar was the lowest in telescopic partial denture. 3. In clasp retained removable partial denture, stress was lower at load site and ridge crest at mid-line, but it was higher at 1st premolar area on vertical load. 4. In attachment removable partial denture, stresses at buccal side of 1st premolar. lingual side of 1st premolar on vertical load, and ridge crest at midline on oblique load were higher. 5. In telescopic removable partial denture, stress at lingual side of 1st premolar was the least in all removable partial dentures, but the stress at load site was higher. 6. In swing-lock removable partial denture, stress at buccal side of 1st premolar was the lowest, and stresses at load site and distal end of residual ridge crest were higher.

  • 본 연구는 수도권 치과병 의원에 내원한 65세 이상의 노인을 대상으로 구강보건행위와 구강건강상태를 파악한 후 보다 나은 삶의 질을 향상하기 위해서 노인의 구강건강증진 프로그램을 개발하는데 기초자료를 얻고자 시행하였다. 분석결과는 다음과 같다. 1. 본 연구의 대상은 남자 40.8%, 여자 59.2%로 여자가 남자보다 많은 비율을 차지했으며, 연령별로는 65세에서 69세가 58.5%로 가장 많았다. 2. 우식경험미처치치아와 우식경험처치치아는 3개 이하가 각각 82.4%, 50.7%로 가장 많았으며, 현존치아는 3개 이하가 28.2%로 가장 많이 나타났다. 3. 여자가 남자보다 구강보건행위의 수준이 높은 것으로 나타났으며(P = 0.00), 생활비 조달방법에서 정부보조금으로 생활을 하는 대상자보다 본인이 급여를 받거나 수입이 있는 대상자가 구강보건행위 수준이 높은 것으로 나타났다(p = 0.02). 4. 주관적 구강건강상태는 우식경험 미처치치아와 음의 상관관계를 보였고, 우식경험미처치치아와 우식경험상실치아, 우식경험처치치아와 현존치아는 양의 상관관계를 보였다. 5. 본인이 직접 생활비를 조달하는 노인들이 우식경험처치치아를 5.4개로 가장 많이 보유하고 있었으며(p = 0.02) 통계학적으로 유의한 차이를 보였다. 6. 잇솔질 방법에서 본인 마음대로 닦고 의 경우 상실치아가 11.8개(p = 0.05)로 다른 여러 가지 방법으로 잇솔질을 하고 있는 노인들에 비해 높게 나타났으며, 이는 통계적으로 유의한 차이를 보였다. 윗니와 아랫니를 따로 닦고 있다는 응답자에서 현존치아가 17.3개(p = 0.00)로 가장 많이 나타났으며, 또한 보건소를 자주 이용하는 노인들의 처치치아는 4.3개로 유의하게 많은 것으로 나타났다(p = 0.00). 이상의 결과를 종합하여 보면 65세 이상의 노인들은 대체적으로 구강건강상태가 양호한 것으로 나타났고, 특히잇솔질방법 등 올바른 구강건강행위를 하는 노인의 구강건강상태가 훨씬 양호하게 조사되었으며, 경제수준도 구강건강상태에 많은 영향을 미치는 것으로 조사되었다. 따라서 우리 치과위생사들은 노인들에게 구강건강을 증진시킬 수 있는 체계적인 노인구강보건교육이 이루어져야 하며, 지역자치단체에서는 노령인구를 위한 보건의료를 확장하여 보건소를 중심으로 적극적인 예방업무와 치료업무가 이루어지도록 치과의료서비스 접근도를 높이는 정책전환이 요구된다. 본 연구는 수도권 일부지역 치과병 의원에 내원한 환자들을 조사 대상자로 선정하였기에 조사기간 동안에 내원하지 않았거나 다른 진료기관을 이용한 노인들은 조사 대상에서 제외되어 우리나라 전체 노인의 구강건강실태를 대변하였다고 할수 없고, 구강검사시 치과병의원의 치과의사의 협조를 얻어 시행하였기에 평가자간의 오차가 다소 발생하여, 향후 검사의 오차를 줄일 수 있는 보다 체계적인 연구가 요망된다.

  • The purpose of this study was to evaluate the adaptation of light cured glass ionomer cement and composite resin using all- etch technique to tooth structure. In this study, class V cavities were prepared on the buccal surfaces of 10 extracted human premolar teeth with cementum margin and teeth were randomly assigned 2 groups of 5 teeth each. The cavities of glass ionomer cement group were filled with the light cured glass ionomer cement(Fuji II LC) and the cavities of composite resin group were filled with the light cured composite resion(P - 50) using all- etch technique with All- Bond 2. The restored teeth were stored in 100 % relative humidity at $37^{\circ}C$ for 48 hours. And then, the roots of the teeth were removed with the tapered fissure bur and the remaining crowns were sectioned occlusogingivally through the center of restorations. Adaptation at tooth - restoration interface were assessed occlusally, gingivally, and axially by scanning electron microscope. The results were as follows : 1. The adaptation to enamel walls of composite resin restorations using All - Bond 2 showed better than glass ionomer restorations. 2. The adaptation to gingival and axial walls of glass ionomer restorations showed better than composite resin restorations using All - Bond 2. 3. In both groups, occlusal margins of restorations showed better adaptation than gingival margins of restorations.
