Background: In Korea, laws for many medical technicians were revised in the Enforcement Decree of the Medical Technicians Act (MTA), which was announced on December 2018, whereas those related to dental hygienists remained unchanged. This study aimed to determine the awareness and opinions of dental hygienists regarding MTA. Methods: Dental hygienist were recruited as participants via convenient sampling in Seoul, Gyeonggi-do, and Chungcheong-do; data from 291 self-reported questionnaire responses were used for the final analysis. We investigated the participants' general characteristics, awareness, and request for the amendment of the MTA. The compliance with the work scope specified in the MTA and level of demand for revision of the MTA were analyzed by independent t-test and one-way analysis of variance. For all statistical analyses, the significance level was set at 0.05. Results: For the 2018 MTA revision, 99 (34.02%) knew that dental treatment assistance and surgery assistance were excluded, whereas 192 (65.98%) did not know. The item "The current medical technician law must be revised" was scored 4.13±0.80 out of 5 points, and significant differences were identified according to the education level, career, and position (p<0.05). The item "It is necessary to institutionalize the expanded work scope beyond the work scope of dental hygienists specified in the MTA" was scored 4.02±1.04 out of 5 points, and significant differences were identified according to age (p<0.05). Conclusion: The participants wanted the MTA to be revised to reflect the real-world work performed by dental hygienists in the dental clinical field. The legal system must ensure the legal protection of the work area of the dental hygienist as an oral health professional, and recognize the legal work scope of the dental hygienist.

Objectives : This research was conducted to find the subjective symptoms of musculoskeletal system for main jobs and job posture. Methods : A survey was conducted from September 15, 2011 to October 7, 2011 and 357 dental hygienists were responded. The survey was consisted of the working environment and medical equipments, psycho-social characteristics, health habits and education, job posture, subjective symptoms of musculoskeletal system pain, and so on. Results : In the survey on the frequency of job posture of dental hygienists by jobs, said they cast down or tilt their head by 15 degrees or more or twist or bend their back. The result of the analysis on the subjective symptoms of musculoskeletal system by main job showed that they experienced a pain in neck, shoulder, and back, although the order differed. The order of subjective symptoms of musculoskeletal system for casting down or turning head by 15 degrees or more, twisting or bending back, having shoulders not parallel to the ground, sitting at the end of a chair, and supporting the whole body with one leg or pressing on a pedal for treatment was from the shoulders to the neck to the back. The order of subjective symptoms of musculoskeletal system for having arms too far from the body or hunching for treatment and bending wrists inward or outward for treatment was from the shoulders to the back to the neck. Conclusions : Due to the characteristics of the job which requires one to have a proper view of a patient's oral cavity, most of the postures included casting down of head or bending of back. Therefore a development of new postures is needed to replace the existing job postures which pressure the musculoskeletal system. And shift rotation can be used as a preventive measure.

With these changes in the environment of dental service, dental hygienists are suggested to change their roles to cope with the changes. Hygienists are putting forth many efforts to promote smooth and efficient dental treatments, and as a practical measure. As a part to cope with such changes. Korea Dental Hygienists Association(KDHA) has prepared the system of Specialized Dental Hygienist and put the system into enforcement through an affiliated organization, Korean Academy of Dental Hygiene. The purpose of this study is to investigate the specialized nurse system in our country's medical environment and the specialized dental hygienist systems in other countries as similar cases comparable to the specialized dental hygienist system in our country and present basic data for the establishment of specialized dental hygienist system. For this study, a survey of dental specialists, such as dentists, dental hygienists and nurses, and patients, has been conducted qualitatively through person-to-person depth interview. The interview questions were related to the need for a specialized dental hygienist system, educational programs, functions and roles, and issues that must be solved for establishment of the system. Based on the interview results, the following conclusions were derived. The specialized dental hygienist system must encourage dental hygienists to possess advanced abilities in clinical practices, present systematic and developmental directions in educational programs, and stimulate specialized dental hygienists to actively work as manager and supervisor, medical health service providers, educators, and researchers. Lastly, for issues that must be solved for the establishment of the system, the duties and jobs of specialized dental hygienists must be defined more concretely, which must be acknowledged by people working in related occupations, citizens and the government. Furthermore, we need to examine the scope of duties of dental hygienists and enact laws and systems to protect the scope. These roles will lead dental hygienists to lay the foundation that allow them to make enthusiastic activities as an oral hygienist and clinician as well as show the way how to act as an educator, a researcher, a manager and an administrator.

This study applied an original survey of an objective National Health Nutriment Research. It picked the youth up from 14 years old to 19 years old and examined an influence relationship of four heads such as DT, DI, DMFT, DMFI which investigated in heads of dental inspections based on an intake frequency questionnaire by food group. It was proved that Korean dietary culture which eats rice and kimchi as staple food had an great effect on DT, DI, DMFT, DMFI And rice and cereals, fruits and vegetables like a cabbage turned out to be factors that can lower dental caries. The dental caries can be reduced by the more intake frequency of rice. And also, intake of fish like anchovy and meats like pork and beef can reduce development of dental caries too. Especially, the larger intake frequency of carbonated drinks and fast food such as hamburger and pizza can make a growth of dental caries.

To find out influence of water fluoridation program on the economic benefit effect, this study analyzed comparatively dental treatment indicators obtained from dental clinics at Sangdang-gu in Chenongju City, fluoridated community and Manan-gu in Anyang City, non-fluoridated community, from January 1, 2003 to the end of June, and the results are as follows: 1. If water fluoridation program is carried out in Anyang, non-fluoridated community, the number of treatment from caries and disease of tissues around dental pulp and root apex from age 6 to 18 for the first half of year 2003 is expected to decrease by 1,272, 636 for low estimation, and 1,908 for high estimation. And the treatment cost is expected to decrease by 40,888,000 Wons, 20,444,000 Wons for low estimation, and 61,333,000 Wons for high estimation. 2. Assuming that water fluoridation program is spread to all over the country, the number of treatment per year is expected to decrease by 2,492,018, 1,246,009 for low estimation, and 3,738,027 for high estimation. And the treatment cost is expected to decrease by 80,105,075,000 Wons, 40,052,537,000 Wons for low estimation and 120, 157,612,000 Wons for high estimation respectively. 3. For Yeong-un water supply management office which has 48,925 water supply personnel, the benefit/cost rate was 2.9 times, and for Jibuk water supply management office which has 239,751 water supply personnel, the benefit/cost rate was 9.0 times. As the water supply personnel increased, the cost increase of water fluoridation program was little and as the scale got large, the economic effect was very large. Improving national oral health is thought to be associated with expense retrenchment of oral health insurance financial. So it may need to extend using tap water to all the area of the country and additionally establish confidence through an active public relations and education of water fluoridation program.

(-)-Epigallocatechin-3-gallate (EGCG), a major flavonoid in green tea has multiple health benefits including chemoprevention, anti-inflammatory, anti-diabetic, and anti-obesity effects. In connection with these effects, EGCG can be a candidate to help the treatment of metabolic diseases. Metformin is a widely used anti-diabetic drug regulating cellular energy homeostasis via AMP-activated protein kinase (AMPK) activation. Therefore, the combination of metformin with EGCG may have additive or synergistic effects on treatment of type 2 diabetes. Nevertheless, there is no report for the pharmacokinetic and/or pharmacodynamic interaction of EGCG with metformin. Here, we evaluated the pharmacokinetic and pharmacodynamic interaction between metformin and EGCG in rats. Pharmacokinetics parameters of metformin were measured after oral administration of metformin in rats pre-treated with EGCG (10 mg/kg) or saline for 7 days. The results showed that there is no significant difference in pharmacokinetic parameters between saline control and EGCG-treated group. In addition, the hepatic AMPK activation by metformin in EGCG-treated rats was also similar to the control. The lack of additive effects of EGCG on AMPK activation or intracellular uptake of metformin was also evaluated in cells in the presence or absence of EGCG. Treatment of HepG2 cells with EGCG inhibited the metformin-induced AMPK activation. Combined results suggested that EGCG has no effect on the pharmacokinetics of metformin but may contribute to metformin action.
