Objectives: The purpose of this study was to examine the association between two major oral diseases and cardiovascular diseases. Methods: Data from the 6th Korean National Health and Nutrition Examination Survey (2013-2015) were used. The study included 12,754 adults, aged ${\geq}19years$, who participated in the questionnaire survey of health related to hypertension, stroke, myocardial infarction, and angina pectoris as well as completed blood tests, anthropometry, and oral examination. Statistical analyses included complex sample frequency, complex sample general linear, complex sample cross-tabulation, and complex sample logistic regression analyses. Results: With respect to the number of Decayed-Missing-Filled-Teeth(DMFT ), patients with hypertension (DMFT 8.05), stroke (DMFT 8.66), and angina pectoris (DMFT 8.24) showed a DMFT score of >2, compared with those who did not have these diseases (p<0.05). Patients with hypertension, stroke, myocardial infarction, and angina pectoris presented an approximately 2.7, 3.5, 4, and 3 times higher incidence of periodontal diseases, respectively, than those who did not (p<0.05). Based on the analysis of the relationship between the number of DMFT and cardiovascular diseases, patients with cardiovascular diseases had a risk of 1.033 higher DMFT than those who did not (p<0.05). As per the analysis of the relationship between periodontal diseases and cardiovascular diseases, patients with cardiovascular diseases had a 2.969 higher risk of periodontaldiseasesthanthosewithout them (p<0.05). Conclusions: Two major oral diseases were found to be associated with cardiovascular diseases. Therefore, to prevent these major oral diseases in patients with cardiovascular diseases, oral hygiene management must be actively performed.

This study aimed to explore possible relationships between self-efficiency and intention to leave in dental hygienists so as to provide basic data for developing solutions to effectively manage dental hygienist man power. A total of 206 dental hygienists from different dental care institutions in Cheonbuk Province were chosen as subjects by a convenience sampling method. Data were collected through a self-reported survey. The results were as follows. The self-efficiency was higher among dental hygienists who were more than 36 years of age, had graduated university, were at their cuurent job longer than 11 years, and reported their annual income to be more than 25 million won. As their age was younger and their education and income levels were lower, their intention to leave was stronger. Also subjects who were unmarried, did not feel satisfaction with their current job, and did not want to stay any longer at the location where they were currently working tended to have higher intention to leave. The higher their self-efficiency, the lower their turnover intention. An examination of the three factors offered by a factor analysis on self-efficiency, 1) sense of competence, 2) sense of confidence, and 3) strong drive, revealed that the higher their sense of competence, the lower their turnover intention. It was also revealed that their self-efficiency had a significant influence on their turnover intention and the most influential factor was their sense of competence.

Objectives: The purpose of the study is to investigate the correlation with subjective oral health status and food preference in elderly people. Methods: Data were extracted from the fifth Korea National Health and Nutrition Survey 2010-2012. The survey data included general characteristics of the subjects, food preference, and subjective oral health status. Food preference was analyzed by assigning score to 63 food categories. The subjective oral health status consisted of toothache within a month, self-perception of oral health, chewing difficulty, mastication difficulty, and speaking difficulty. Data were analyzed by frequency analysis, descriptive statistics, ${\chi}^2$ test, t-test, and ANOVA using SPSS 22.0 program. Results: Elderly men had a tendency to have a liking for all food categories except for fruit. Difficulty in chewing and mastication was shown in those who had older age, lower education, lower monthly income, and national basic livelihood security. Difficulty in speaking was found in those who had older age, lower education, and national basic livelihood security. Self perception of oral health status was closely related to food preference for pulses and potatoes, fish, vegetables and others(p<0.05). Difficulties in chewing and mastication had relation to all food categories excepting cereals, lipids and sugars(p<0.05). Speaking difficulty were significantly different in pulses, potatoes, meat, eggs, vegetables, fruits, milk, dairy products, and others(p<0.05). Conclusions: Poor subjective oral health status was closely related to food preference. It is necessary to educate that maintenance of good oral health is to ingest the balanced nutrition in the elderly people.

Aplastic anemia is a hematopoietic disorder characterized by marked reduction or absence of erythoid, granulocytic, and megakariocytic cells in the bone marrow with resultant pancytopenia. To control of infection & bleeding secondary to leukopenia and thrombocytopenia, the inflammatory lesions in oral & maxillofacial area should be removed. Material & Method: The extractions were performed on 21 patients with severe aplastic anemia. The initial, pre-operative and postoperative CBCs were checked up. Amount and kind of transfused platelet in each patient and increment of platelet level were recorded. The complications were documented. Result : A mean of 2.9 teeth were extracted from each patient(ranging between 1 and 13). Furthermore, surgical extractions including ostectomy and odontectomy of the third molar were performed on 11 patients. The preoperative WBC levels presented between $600/{\mu}L$ and $5000/{\mu}L$(mean $2376/{\mu}L$). The WBC values decreased by an average of $145/{\mu}L$ per patient after extractions had been performed. The teeth of 16 patients were extracted under 10.0g/dL, and the mean change in postoperative hemoglobin levels in comparison with preoperative hemoglobin levels was -0.06 per patient. The initial platelet levels were between 1000/(L and $81,000/{\mu}L$(mean $20,174/{\mu}L$). In five patients, extractions were performed with platelet levels less than $50,000/{\mu}L$. Conclusion : The results suggest that more active and preventive treatments in the oral and maxillofacial area are possible and are necessary to remove the infectious foci on the patients with severe aplastic anemia. We report the results of our experiences and literature reviews in treatment of the patients with severe aplastic anemia in our department.

A new method for early caries diagnosis was proposed and tested through a home-made optical examination system that used quantitative light fluorescence (QLF) and digital imaging fiber optic transillumination (FOTI) (DIFOTI), with light sources across a wide spectral range, from 350 nm to 1,000 nm. The front-illuminated infrared light scattering image (FIR) showed similar diagnostic abilities to that of DIFOTI. The FIR method was invented based on the observation that caries lesions lose the high transmittance and low scattering properties of benign enamel tissue. There are various methods for the early diagnosis of caries, such as visual examination, exploration, X-ray radiography, QLF, FOTI, and infrared fluorescence (diagnodent). Among them, methods based on optical properties are regarded as having the most potential. A comparative study was performed between the FOTI, QLF, diagnodent, optical coherence tomography, and FIR scattering image methods, using 20 extracted teeth samples with early caries. A scale of lesion measurement based on optical image contrast was proposed. The statistical analysis showed a significant correlation between the DIFOTI and FIR methods (r = 0.35, p < 0.05). However, the QLF and diagnodent methods showed little association with FIR images, as they have different detection principles as compared with FIR. Tomographic images obtained by OCT, using 1,330 nm super luminescent LED as a gold standard of tooth structure, verified that the FOTI and FIR results correctly represented the lack of homogeneity in dental tissue. The newly proposed FIR method attained similar diagnostic results to those of FOTI, but with an easier approach.
