Background: Swallowing function deterioration is a common problem experienced by older adults worldwide. Many studies have been conducted to improve swallowing function in older adults; however, due to differences in intervention methods and study designs, it is difficult to draw a common conclusion. This study aimed to analyze trends and intervention methods in studies of swallowing function intervention for older adults conducted from 2010 to 2022, to establish a systematic approach for developing interventions to improve swallowing function in older adults and to provide evidence for this approach. Methods: Literature research was conducted for studies published between 2010 and 2022 that applied to swallow function interventions to adults aged 60 years or older. Databases including PubMed, Medline, RISS, Science On, KISS, and KCI were used. From a total of 1,164 articles searched using keywords, 20 articles were selected for final analysis. Results: The number of published articles steadily increased over time, and the intervention period was most commonly 6 or 8 weeks. The types of interventions included focused exercises to improve oral muscle strength in 12 articles and programs incorporating education, practice, and expert management in 8 articles. Among the focused exercises, tongue-strengthening exercises were most common in 4 articles. The evaluation variables for intervention effects were muscle strength evaluation, oral function evaluation, quality of life, and oral health and hygiene status. Muscle strength and oral function evaluations were statistically significant in focused exercise interventions, while the quality of life and oral health and hygiene status was significant in program interventions. Conclusion: This literature review is meaningful as a study that can be used to select the intervention period and program contents when planning an elderly swallowing intervention program.

Objectives : This study is aimed to help the dental hygiene department students to improve their adaptive ability to the field work by letting them know the performing levels required of the job world, by renovating the knowledge-centered curriculum, and by finding out the core competencies needed for successfully performing their duties and tasks in the work field. Methods : The survey tool was recomposed through the examination of the preceeding studies on basic vocational competencies and skills, and the survey has been done to 200 dentists in Seoul and Gyunggi provice. Results : 1. As for the job-getting routs, 35.1% of them finds their jobs through the job portal sites, and 21.3% through the recommendation by professors. So we can see the meaningful difference in the employment ways. 2. Dental hygiene clinics think that the purpose of their cooperation with the colleges is mainly to secure human resources by requiring the colleges to give field-centered education the colleges through. 3. The clinics for dental hygienic students' field learning have a great power for hiring the students. So it is necessary to set up a good management system of the clinics for dental hygienic students' field learning in order to reinforce the students' competitive power in getting jobs. 4. The priorities in basic working abilities needed for the task performance are in the order of vocational responsibility, self-managing & developing ability, interpersonal skill, and problem solving ability. 5. The core competencies required of those who graduate from dental hygiene school show the following scores by Likert measurement; good personality and vocational consciousness 2.16(${\pm}.677$), understanding power of major-related knowledge 2.19(${\pm}.723$), field adapting ability 2.31(${\pm}.748$), get-along-with ability 2.32(${\pm}.799$), interpersonal skill 2.42(${\pm}.768$), and self-development ability such as getting certificates 2.43(${\pm}.729$). Among the core competencies, the only meaningful factor which influences on their satisfaction measurement has been identified as the professional ability related to the major. Conclusions : The results suggest that the knowledge and skill related to the major are core competencies of able human resources and closely related with the professionality of the job, and so they are very important. However, job basic abilities are also proved to be important, which reinforce the students' activeness, self-regulation, and creativeness, and help them to pursue their lasting growth in their abilities.

Migrant Worker are rapidly increasing in Korea since 1990. They are nowadays main sources of laborer groups engaging in medium-sized factories. The purpose of this study is to provide the basic information to establish proper oral health policy. Dental caries and periodontal disese are the most common disease that occur in the mouth. Periodontal disease is the most common disease in humans and the biggest reason for the loss of the teeth in the adult population. The CPITIN has been developed jontly by the international Dental Federation and the World Health Organization. CPITN is now an established index of level, of periodontal condition in populations for which specific intervention might be considered. This study was conducted to obtain the information regarding to CPITN of migrant workers located in Daegu, Questionaire survey was carried out for 289 workers from July 9 to August 8, 2006. Total survey was 289, 224 males and 65 females. The result was as follows: First, The number of nationality was 14. The first majority was China as 31.8% Among 14 nationalities were Cambodia 18.0%, Vietnam 12.8%, Sri Lanka 12.1%, Indonesia 7.3%, Nepal 4.2%, the other 13.8%, those who are aged from 20 to 29 were 43.9%, and salary from 1,000,000 won to 1,490,000 won 51.2%.(as for their residence, those who resided) over 3 years were 42.6% and not insured reached 68.5%. Second, more than 93.4% of the subjects need periodontal treatment, only 4.9% of non-smoker was health periodontal states, four times frequency of tooth brushing per a day was 16.7%. Third, 28.7% of migrant workers had experienced visit of dental clinic, and 22.9% had received treatment of decayed tooth. Fourth, It is difficult for them 65.1% of them to visit dental clinic in korea, the First was a communication problem and the second was time. Fifth, Most of them didn't have a oral health education but 85.1% of them said that they wish they attend oral health education. We conclude that the situation of migrant workers was very bad considering their working conditions, circumstances, and health condition. According to this study, more than 93.4% of the people need periodontal treatment. Besides they didn't have accurate knowledge about prevention of periodontal disease.

STATEMENT OF PROBLEM. Macroscopic and especially microscopic properties of implant surfaces play a major role in the osseous healing of dental implants. Dental implants with modified surfaces have shown stronger osseointegration than implants which are only turned (machined). Advanced surface modification techniques such as anodic oxidation and Ca-P application have been developed to achieve faster and stronger bonding between the host bone and the implant. PURPOSE. The purpose of this study was to investigate the effect of surface treatment of titanium dental implant on implant stability after insertion using the rabbit tibia model. MATERIAL AND METHODS. Three test groups were prepared: sandblasted, large-grit and acid-etched (SLA) implants, anodic oxidized implants, and anodized implants with Ca-P immersion. The turned implants served as control. Twenty rabbits received 80 implants in the tibia. Resonance frequencies were measured at the time of implant insertion, 2 weeks and 4 weeks of healing. Removal torque values (RTV) were measured 2 and 4 weeks after insertion. RESULTS. The implant stability quotient (ISQ) values of implants for resonance frequency analysis (RFA) increased significantly (P <. 05) during 2 weeks of healing period although there were no significant differences among the test and control groups (P >. 05). The test and control implants also showed significantly higher ISQ values during 4 weeks of healing period (P < .05). No significant differences, however, were found among all the groups. All the groups showed no significant differences in ISQ values between 2 and 4 weeks after implant insertion (P >. 05). The SLA, anodized and Ca-P immersed implants showed higher RTVs at 2 and 4 weeks of healing than the machined one (P < .05). However, there was no significant difference among the experimental groups. CONCLUSION. The surface-modified implants appear to provide superior implant stability to the turned one. Under the limitation of this study, however, we suggest that neither anodic oxidation nor Ca-P immersion techniques have any advantage over the conventional SLA technique with respect to implant stability.
