Background: The health of the economically active population contributes to increased corporate productivity by reducing the productivity loss caused by disease and increasing job efficiency, which in turn is a national benefit. Since the economically active population is a concept encompassing workers and a source of economic development for a country, that population's health should be treated with importance not only from a personal standpoint but also at a national level. Methods: In this study, data of 11,007 adults aged 20 years and older who participate in economic activities were analyzed in the five-year Korea Health Panel Study from 2010 to 2014 including the number of dental visits and dental medical expenses. Results: Factors related to "gender," "education level," "age," "duty category," "income level," "employment type," "national health insurance," and "chronic disease status" of the economically active population are affected in relation to the number of visits and dental medical expenses. The number of dental visits increased with higher education levels (p<0.001), and the number of visits to the dentist increased with older age (p <0.001). Dental medical expenses were 91,806 Korean won (KRW) more for "white-collar workers" than for "blue-collar workers" (p<0.03), and 127,674 KRW more for "regular workers" than for "atypical workers" (p<0.02). Conclusion: When it is necessary to improve policies to enhance the efficiency of the distribution of health and medical resources in the overall balance of the dental health sector, we should try to identify various factors of oral health disorder due to income inequality among the classes according to the country's employment type in order to find ways to reduce the health gap among the social classes.

최근 들어 치아의 심미적인 개선을 위해 전치부 보철 치료를 하는 경우가 많다. 하지만 전치부 심미 보철치료이후 환자가 발음, 저작 등 기능적으로 불만족스럽게 생각하는 경우가 종종 있다. 전치부는 심미적으로 중요할 뿐만 아니라 교합과 관련하여서도 중심위 다음으로 중요한 전방유도가 성립되는 부분으로, 잘못된 전방유도 설정으로 인해 구치부의 교합간섭을 초래할 수 있다. 또한 새롭게 설정된 전치부 보철물의 전방유도가 환자의 기능로(envelope of function)과 조화를 이루지 않을 시 환자가 불편감을 나타낼 수 있다. 본 증례는 전치부 심미 보철 이후 부정확한 발음 및 안정적인 접촉이 없어서 불안정한 교합, 전반적인 불편감을 호소하는 환자에서 체계적인 진단과 치료과정을 통해 보철물을 재수복하여 환자와 술자 모두에게서 심미적으로, 그리고 기능적으로 만족스러운 결과를 얻었기에 보고하는 바이다.

This study examined the opinions of dentists on dental hygienists' practice and attempted to use it as the basis for the revision and modification of the legal system associated with dental hygienists. The subjects of this study were a total 15 dentists, including two from Gyeonggi, two from Gangwon, two from Gyeongsang, two from Jeolla, two from Chungcheong, and two from Seoul, who were surveyed face-to-face. This study revealed that from the perspective of dentists, the most important job of dental hygienists was scaling, and the most difficult job was patient counseling and response. From the perspective of dentists, there is a difference between what the dental hygienists actually perform and what is legal, and there is a high need for change. The inclusion of dental hygienists in the category of medical personnel should be accomplished to cover the practice of dental care support, and dentists opinionated that it is appropriate for dental hygienists to be included in the category of medical personnel because they directly perform oral health-related procedures. A careful review of the dental hygienists' scope of work should be performed to ensure that revisions to the law are made in accordance with the dental hygienists' actual practice. Further, it is necessary to revise the Medical Law and include dental hygienists among the medical personnel and simultaneously revise the scope of work of dental hygienists to reflect the actual dental practice.

Objectives: The objectives of this study were to assess oral health knowledge and behavior levels of community pharmacists as a step toward projecting them to play the role of oral health partners and to confirm pharmacists' willingness to participate in oral health education programs. Methods: t-test and one-way analysis of variance were performed to analyze the data, and correlation analysis was also performed. Results: The mean score for pharmacists' oral health knowledge was 7.29 out of 10. Of the 12 questions asked, the correct answer rate was highest for the question about the effect of smoking cessation on periodontal disease prevention; conversely, the correct answer rate was lowest for the question about the effect of taking medication for gingival infections on periodontal disease prevention. The mean score for pharmacists' oral health behavior was 2.97 out of 4 points. Of all oral health behaviors, brushing twice a day was the most practiced, whereas immediately visiting a dentist in case of an oral health issue was the least practiced. Pharmacists' oral health knowledge and behavior levels showed a weak positive correlation with their intention to participate in oral health education programs. Conclusions: Oral health education programs are necessary to improve community pharmacists' oral health knowledge and behavior.

Purpose : As the number of patients with systemic diseases is increasing in the old, the relevance of oral health is gaining particular research interest. To provide fundamental resources for dental services, this study examined the relationship between doctors' diagnoses of circulatory diseases and patients' awareness of oral health and oral care behaviors. Methods : SPSS 26.0 was used to assess various variables, including doctor's diagnosis of circulatory diseases, gender, age, household income quintile, participation in economic activity, marital status, subjective level of oral health awareness, mastication discomfort, speaking and chewing discomfort, dental inspection, use of oral care goods, teeth brushing during the previous day, and untreated oral conditions. Results : The circulatory diseases suffered by the subjects were as follows: 56 % high blood pressure, 36 % dyslipidemia, 6 % stroke, and 8 % myocardial infarction or angina. A higher age meant a higher diagnosis rate of high blood pressure (p<.001) and stroke (p<.001). Those with dyslipidemia showed a higher rate of receiving oral inspection (p=.040), and an untreated oral condition was more frequently observed among those not diagnosed with the disease (p=.035). The subjects who were not diagnosed with stroke showed a higher rate of oral inspection (p<.001), while those who had a prior experience of stroke suffered a higher rate of mastication discomfort (p=.020). People who had high blood pressure showed a lower rate of using oral care goods (p<.001), and those diagnosed with stroke showed a lower rate of brushing teeth the previous day. Conclusion : This study found a correlation between the diagnosis of circulatory diseases and the awareness of oral health and oral care behavior. Consequently, oral health education should be included in mental health-related education, and customized training to teach teeth brushing and the use of oral care goods should be provided to patients with circulatory diseases during dentist visits.

This systematic review evaluates current evidence regarding the feasibility of using needleless jet injection instead of a conventional local anesthetic needle. EBSCO, ProQuest, PubMed, and Scopus databases were used to identify relevant literature published in English from 2005 to 2020. Ten studies were selected. Five of them were randomized clinical trials, 3 case-control studies, and 2 equivalence trials. Using the Critical Appraisal Skills Program checklist, 6 studies scored between 67% and 100%, and 4 studies scored between 34% and 66%. According to Jadad's scale, 2 studies were considered strong, and 8 studies were considered moderate in quality. The results of the 10 studies showed differences in patient preference for needleless jet injection. Needleless injection technique has been found to be particularly useful in uncooperative patients with anxiety and needle phobia. Needleless jet injection is not technique sensitive. However, with needleless jet anesthesia, most treatments require additional anesthesia. Conventional needle anesthesia is less costly, has a longer duration of action, and has better pain control during dental extraction. Needleless jet anesthesia has been shown to be moderately accepted by patients with a fear of needles, has a faster onset of action, and is an efficient alternative to conventional infiltration anesthesia technique.
