  • The purpose of this study was to identify the risk of dysphagia among patients that visited prosthodontics department, and evaluate the difference in risks arising from oral conditions and disease in order to preliminarily intervene the various influencing factors of dysphagia. A questionnaire was given to patients that were aged 65 years or older who visited the prosthodontics department between September to December 2017. The data was collected and analyzed using the t-test, $x^2-test$ and logistic regression analysis. The mean age of the patients was 75 years. Out of 300 patients, 206 patients (68.7%) had a risk of dysphagia. There were statistically significant differences between the -non-risk and risk groups, which included the number of natural teeth, total number of teeth including prosthesis, denture use, denture discomfort, number of tooth brushing, oral dryness, digestive system diseases, and musculoskeletal diseases. Among these, oral dryness was a risk factor while the total number of teeth, including natural teeth and prostheses, served as a protective factor. More than half of the elderly patients were at risk of dysphagia. Oral dryness is influenced by many factors and it should continuously be managed. Patients should fully recover their masticatory function by preserving the remaining teeth and compensating for the missing teeth. A dental practitioner should be fully aware of the risk of dysphagia in elderly patients and be able to intervene and offer proper patient health care in advance through treatment guidelines and education.

  • Purpose: This study investigated the association between the objective indicator of masticatory function assessment and the masseter muscle thickness (MMT) using ultrasound imaging. Methods: A total of 99 subjects (males: 24, females: 75, mean age: 76) were analyzed. The maximum bite force (MBF) was measured with a pressure-sensitive sheet and an image scanner. The mixing ability index (MAI) was calculated by image analysis after asking the subjects to chew a wax specimen. The MMT during rest and clenching were obtained with a diagnostic ultrasound system, and the difference in MMT during rest and MMT during clenching was defined as the difference in masseter muscle thickness (DMMT). Multiple regression analysis was performed to determine the independent variables affecting MBF and MAI. Results: The MBF showed correlation with the number of remaining teeth (β=0.346, p=0.002) and DMMT (β=0.251, p=0.011). The MAI correlated with only the number of remaining teeth (β=0.476, p<0.001). Conclusions: The DMMT reflects the state of masseter muscle contraction, and can be used as a predictor as well as the number of teeth when assessing masticatory function.

  • Objectives: The purpose of the study was to investigate the association between remaining functional teeth and oral health-related quality of life using Geriatric Oral Health Assessment Index(GOHAI) in the elderly. Methods: A self-reported questionnaire was completed by 237 female elderly in Daegu from May to September, 2015. The questionnaire consisted of general characteristics of the subjects and Geriatric Oral Health Assessment Index(GOHAI). A total of 216 female elderly data were analyzed for oral health status and their GOHAI score. Data were analyzed using SPSS 23.0 version. Logistic regression analysis showed the association of functional teeth and GOHAI score. Results: Number of functional teeth can affect oral health related quality of life in the elderly. When functional teeth is small, the odds ratio(OR) was 2.119(95% CI: 1.215-3.696). After adjusting age, residence type and education, OR was 1.900(95% CI: 1.060-3.399). Policies to preserve natural tooth should be recommended for increasing quality of life in general. Conclusions: This study showed significant association between number of functional teeth and the GOHAI score of the elderly women.

  • There were many studies that distribute the partial edentulous states and examine the removable partial denture designs in the planning of removable partial denture treatment. This study was performed in the point of removable partial denture prescription to evaluate partial edentulism and its removable partial denture designs. The data was collected from the dental laboratory of each three dental colleges in Seoul and from two dental laboratories only for removable partial dentures as a prescription form. A total of 1411 cases with prescription form collected from dental laboratories were distributed for this study, then 788 cases were selected for this study. The case selection was done according to the contents of prescription form. The selected cases were divided into maxillary arch and mandibular and classified in terms of types of major connector and direct retainer, unbroken anterior teeth, Kennedy classification, the number of remaining teeth, and distribution of age and sex. The analyzed results were as follows : 1. The Kennedy classification I showed highest frequency both in maxilla and mandible. 2. The arch distribution of removable partial denture was 50.08% for maxilla and 49.92% for mandible. 3. The highest frequency in the distribution of direct retainer was the RPA clasp design. 4. The frequency of unbroken anterior 6 was 73.36% for maxilla and 82.30% for mandible. 5. The design of broad palatal strap and lingual bar revealed the highest prevalence in the major connector construction. 6. The mean number of remaining teeth per arch was 8.25 for maxilla and 8.37 for mandible. 7. The mean age of the patients supplied with removable partial denture was 52.25 years for men, 51.68 years for women, 52.11 years for maxilla, and 51.76 years for mandible and women showed more prevalence.

  • Objectives: This study aimed to find a way to solve oral health inequality in old age by understanding the effect of the socioeconomic level of the elderly on oral health. Methods: We used data from the 7th Korea National Health and Nutrition Examination Survey. A chi-square test was performed to investigate differences in oral health according to socioeconomic status and demographic and oral health-related factors. Socioeconomic status and oral health inequality were analyzed using multiple logistic regression. Results: The average number of teeth in the elderly was 17.20, which is insufficient for the minimum number of teeth required for mastication. In the analysis of the correlation between socioeconomic status and oral health inequality, education level, income level, and home ownership were factors influencing the oral health of the elderly; education level was found to have the strongest effect. Conclusions: Oral health inequality according to socioeconomic status was confirmed, and it is necessary to measure the level of oral health inequality with active efforts at the government level to resolve the gap in oral health by social class.

  • Purpose: The purpose of this study was to investigate whether panoramic radiographs were useful in predicting osteoporosis. Materials and Methods: 50 postmenoposal women between the age of 41.8 and 78.5 were classified as normal and osteoporosis groups according to the bone mineral density of lumbar vertebrae. Panoramic radiographs were taken. Age, body mass index, remaining mandibular teeth, mandibular cortical thickness and morphology, and fractal dimensions at periapical areas of mandibular first molars were evaluated to differentiate the two groups. Results: The age of osteoporotic group was statistically significantly higher than that of normal group (p<0.05), but not the body mass index or number of remaining mandibular teeth. The mean fractal dimension of osteoporotic group was $1.391{\pm}0.085$, and was significantly lower than that of the normal group, which was $1.523{\pm}0.725$ (p<0.01). Thick mandibular cortical thickness was common in normal group, whereas thin or very thin mandibular cortical thickness was common in osteoporotic group and the difference was significant (p < 0.05). C2 pattern was common in normal group followed by C1, whereas C2 was common in osteoporotic group followed by C3. The difference was statistically significant (p< 0.0 1). Conclusion: Age, mandibular cortical thickness and shape, fractal dimension on panoramic radiographs were useful in predicting osteoporosis.

  • Purpose: Vitamin D deficiency may cause bone loss and increased inflammation, which are well-known symptoms of periodontal disease. This study investigated whether serum 25-hydroxyvitamin D (25(OH)D) levels are associated with periodontal disease status and tooth loss. Methods: Cross-sectional data from 5,405 individuals aged ≥50 years (2,253 males and 3,152 females) were obtained from the 2008-2010 Dong-gu study, a prospective cohort study of risk factors for chronic diseases. Periodontal examinations were conducted to evaluate the number of remaining teeth, the periodontal probing depth (PPD), the clinical attachment level (CAL), and bleeding on probing. The percentages of sites with PPD ≥4 mm and CAL ≥4 mm were recorded for each participant. The severity of periodontitis was classified using the Centers for Disease Control and Prevention and the American Academy of Periodontology case definitions. Serum 25(OH)D levels were classified as reflecting severe deficiency, deficiency, insufficiency, or sufficiency. Multivariate linear regression analysis was performed to assess the associations of serum 25(OH)D levels with periodontal parameters and the number of remaining teeth after adjusting for confounders including age, smoking status, alcohol consumption status, month of blood collection, and physical activity. Multivariate logistic regression was used to evaluate the association between serum vitamin D levels and severe periodontitis. An overall statistical analysis and a stratified analysis by sex were performed. Results: Overall, the rates of severe deficiency, deficiency, insufficiency, and sufficiency were 6.5%, 67.9%, 22.4%, and 3.2%, respectively. After adjustment for confounders, vitamin D levels were directly associated with the number of remaining teeth, an association that was significant in males, but not in females. Sufficient serum 25(OH)D was associated with a low frequency of severe periodontitis. Conclusions: This population-based cross-sectional study indicates that low serum 25(OH) D is significantly associated with tooth loss and severe periodontitis in Koreans aged 50 years and older.

  • 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.

  • 본 연구는 충남 A시 보건소 방문보건팀에 등록된 방문건강사업 대상 노인 300명을 대상으로 구강건강 관련 삶의 질과 관련 요인을 조사하여 취약계층 노인들의 삶의 질 향상과 구강건강을 유지, 증진시키기 위한 지역사회 프로그램개발을 위한 기초자료로 제공하고자 연구되었으며 그 연구 결과를 요약하면 다음과 같다. 방문건강사업 대상 노인의 평균 연령은 77.1세였고, 평균 잔존 치아 수는 12.7개, 주관적 건강인지도 평균은 2.27, 일상생활점수 평균은 7.39로 나타났으며 대상자의 91.0%가 1개 이상의 만성질환을 가지고 있었다. GOHAI 점수의 평균은 37.36으로 나타났으며 점수가 낮았던 문항은 구강상태에 행복한 경험이 없음, 걱정이 있음, 단단한 음식을 씹을 때 문제가 있음의 순이었다. 구강보건행태에 따른 GOHAI의 관계는 점심식사 후 칫솔질, 구강위생용품 사용, 무자격자에 의한 진료경험, 구강검진, 스케일링 경험에서는 통계적으로 유의하지 않았으나, 미 충족 치과진료 여부는 유의한 차이가 있었다(p<0.001). GOHAI의 총점에서는 잔존 치아수(p<0.001)와 나이에서 유의미한 차이가 있었으며 하위요인에서는 남성이 통증과 불편요인에서 점수가 높았고(p<0.05), 74세 이하에서 기능제한요인의 점수가 높았다(p<0.01) 잔존 치아 수에서는 통증과 불편요인을 제외한 모든 요인에서 유의미한 차이가 있었다(p<0.001). GOHAI에 영향을 미치는 요인은 연령(p<0.05), 잔존 치아수(p<0.001), 주관적 건강 인지도(p<0.001)로 나타났다. 이상의 연구결과에 따르면 방문건강사업 대상 노인의 구강건강평가지수 점수는 낮은 편이며 연령, 치아수, 주관적 건강 인지도와 연관성이 부분적으로 확인되었기에, 방문건강대상 노인의 구강건강관련 삶의 질을 높이기 위해 치아기능 회복을 위한 보철물 제작 등 틀니 지원 확대를 위한 국가 재원 외에 지방자치단체 예산을 확보할 필요가 있으며, 장착된 의치 관리 및 구강건강증진과 관련된 프로그램이 지속적으로 개발될 필요성이 있다.
