This study aimed to examine the relation between subjective oral hygiene status of the elderly and oral health impact profile and to present it as basic data for the improvement of quality of life and oral care. The study subjects were 231 elderly people aged 65 and over. This study measured the oral health behavior and subjective oral hygiene status based on cross analysis by calculating the median of OHIP-14 to divide the above-median group into a subgroup and the below-median group into a superordinate group. Correlation and regression analyses were performed to examine the effects on the oral health impact profile. The oral health impact profile according to oral health behaviors was not significant. The oral health impact profile based on the subjective oral hygiene states is currently affected by oral hygiene status, masticatory problems, toothache, xerostomia and halitosis. As a result of regression analysis to confirm the effect on the oral health impact profile, much experience of masticatory problems, toothache, xerostomia and gum diseases is the most influential. This shows that the subjective oral hygiene status is not healthy as the oral health impact profile is high. It is considered necessary to establish an oral health promotion program to improve the quality of life of the elderly and active oral care methods in the future.

Dental implants are required to have biomechanical functions and biostability in order to perform authoring, pronunciation, and aesthetic functions in the oral cavity. In terms of biostability, pure titanium for medical have good biostability and no rejection in the alveolar bone. with appropriate strength in terms of strength as well as biocompatibility. In recent years, various surgical methods and devices have been developed to improve the convenience and safety of the procedure. However, as the number of procedures increases, the screw loosening of the abutment screw connecting the artificial root and the abutment There are many reports of artificial root and abutment fracture. Fig. 1 is an example of a case where the upper part of the abutment screw is arbitrarily modified to remove the abutment by the abutment fracture due to the loosening of the abutment screw. The fundamental cause of abduction of the abutment screw is caused by the slight movement due to the lowering of the retention force of the abutment screw. It is necessary to minimize loosening of the abutment screw to avoid problems such as fracture during the period of using the implant. The purpose of this study is to investigate the structure of the abutment screw to prevent the loosening of the abutment screw by forming 0.5mm slot.

The purpose of this study was to examine the self-rated oral health status of industrial workers and influential factors for their work loss caused by dental care in an effort to prepare some information on policy setting about the promotion of the oral health of industrial workers and on the prevention of their oral diseases. The married industrial workers experienced work loss due to dental care more commonly than did the unmarried workers ($x^2=5.10$, p<0.05). In addition, the workers who found themselves to be in worse health experienced significantly more work loss ($x^2=29.69$, p<0.001). The workers who received treatment for oral diseases experienced significantly more work loss than those who did not receive treatment ($x^2=14.60$, p<0.001). In addition, the workers who had oral symptoms requiring treatment experienced more work loss than the others who not ($x^2=11.08$, p<0.01). The experience of not receiving treatment for a perceived oral disease was more dominant among the workers who found themselves to have an oral disease but did not receive treatment than among those who received treatment (p<0.001). Regarding factors affecting the work loss of the industrial workers caused by dental care, the workers whose monthly mean income was larger and who found themselves to be in worse health had significantly more experience of absenting themselves from the office or of leaving work early (p<0.001).

Dental health care in modern society has gradually been developing with patients'expectation, desire, and medical knowledge according to the changes in the medical industry. Dental marketing strategy is necessary to construct a better dental health environment in order to cope with customers' changes and desire. The purpose of this study was to evaluate the positive comments by word-of-mouth experience, quality of dental clinic service and customer satisfaction among dental patients. The study surveyed 5oo subjects being treated at 6 dental clinics in Seoul and Gyeonggi province. It was conducted from March 22 to April 9, 2010. The subject groups with a positive experience through word - of - mouth who had a perception about the quality of dental clinic service (p<.001) and customer satisfaction (p<.001) were higher than other groups who had no comments on their dental treatment and clinics. The results showed that there was a correlation(r=. 852, p<.001) between the positive comments by word-of- mouthabout the quality of dental clinics service and customer satisfaction. The perception of dental clinic service and patients' satisfaction with positive comments by word of mouth was highly recognized by older and more experienced patients of dental treatment. Therefore, the results suggest that empirical information on important factors about strategic marketing lead to positive comments by word of mouth experience for patients in dental clinics.

The purpose of this study is to investigate the effects of awareness of oral health on oral health status and oral health behavior with subjects of students in the middle school which is the important period when lifetime set of teeth is completed with eruption of the second molar tooth and complete set of permanent teeth, and provide the basic data for development of oral health program for adolescents. We examined oral condition and conducted the survey about students' awareness of oral health and behavior in the middle school located in JeonJu. As the results of oral examination, dental caries and malocclusion were higher in female students and periodontal disease was higher in male students (p < 0.038). There was no significant difference in awareness of oral health between male and female students. However, M = 4.08 out of 5 point scale, which was high. For oral health behaviors, female students (M = 4.508) was higher than male students (M = 4.257) in the question of 'I visit the dental office when my gums are bleeding'. Female students (M = 4.547) was higher than male students (M = 4.333) in the question of 'I use the dental floss after brushing my teeth'(p<0.05). Awareness of oral health gave the significant effect on the oral health behavior at 95 % confidence level. Therefore, the education for oral health behavior is required to improve oral health and studies are needed to present the development of program for awareness and knowledge of oral health affecting behavior.

Dementia is an umbrella term that describes the loss of thinking, memory, attention, logical reasoning, and other mental abilities to the extent that it interferes with the activities of daily living. More than 50 million individuals worldwide live with dementia, which is expected to increase to 131 million by 2050. Recent research has shown that poor oral health increases the risk of dementia, while oral health declines with cognitive decline. In this narrative review, the literature was based on the "hypothesis" that dementia and oral health have a close relationship, and appropriate oral health and occlusal rehabilitation treatment can improve the quality of life of patients with dementia and prevent progression. We conducted a literature search in PubMed and Google Scholar databases, using the search terms "dementia," "major neurocognitive disorder," "dentition," "occlusion," "tooth loss," "dental prosthesis," "dental implant," and "occlusal rehabilitation" in the title field over the past 30 years. A total of 131 studies that scientifically addressed dementia, oral health, and/or oral rehabilitation were included. In a meta-analysis, the random effect model demonstrated significant tooth loss increasing the dementia risk 3.64-fold (pooled odds ratio=3.64, 95% confidence interval [2.50~5.32], P-value=0.0348). Tooth loss can be an important indicator of cognitive function decline. As the number of missing teeth increases, the risk of dementia increases. Loss of teeth can lead to a decrease in the ascending information to the brain and reduced masticatory ability, cerebral blood flow, and psychological atrophy. Oral microbiome dysbiosis and migration of key bacterial species to the brain can also cause dementia. Additionally, inflammation in the oral cavity affects the inflammatory response of the brain and the complete body. Conversely, proper oral hygiene management, the placement of dental implants or prostheses to replace lost teeth, and the restoration of masticatory function can inhibit symptom progression in patients with dementia. Therefore, improving oral health can prevent dementia progression and improve the quality of life of patients.
