Objectives: The purpose of this study was to evaluate the effect of Dental Practicality Index (DPI) training using an online video on the treatment planning decisions and confidence level of dental undergraduates (DUs). Materials and Methods: Ninety-four DUs were shown 15 clinical case scenarios and asked to decide on treatment plans based on 4 treatment options. The most appropriate treatment plan had been decided by a consensus panel of experienced dentists. DUs then underwent DPI training using an online video. In a post-DPI-training test, DUs were shown the same clinical case scenarios and asked to assign the best treatment option. After 6 weeks, DUs were retested to assess their knowledge retention. In all 3 tests, DUs completed the confidence level scale questionnaire. Data were analyzed using the related-samples Wilcoxon signed rank test and the independent-samples Mann-Whitney U test with the level of significance set at p < 0.05. Results: DPI training significantly improved the mean scores of the DUs from 7.53 in the pre-DPI-training test to 9.01 in the post-DPI-training test (p < 0.001). After 6 weeks, the mean scores decreased marginally to 8.87 in the retention test (p = 0.563). DPI training increased their confidence level from 5.68 pre-DPI training to 7.09 post-DPI training. Conclusions: Training DUs using DPI with an online video improved their decision-making and confidence level in treatment planning.

Managing pain and anxiety in patients has always been an essential part of dentistry. To prevent pain, dentists administer local anaesthesia (LA) via a needle injection. Unfortunately, anxiety and fear that arise prior to and/or during injection remains a barrier for many children and adults from receiving dental treatment. There is a constant search for techniques to alleviate the invasive and painful nature of the needle injection. In recent years, researchers have developed alternative methods which enable dental anaesthesia to be less invasive and more patient-friendly. The aim of this review is to highlight the procedures and devices available which may replace the conventional needle-administered local anaesthesia. The most known alternative methods in providing anaesthesia in dentistry are: topical anaesthesia, electronic dental anaesthesia, jet-injectors, iontophoresis, and computerized control local anaesthesia delivery systems. Even though these procedures are well accepted by patients to date, it is the authors' opinion that the effectiveness practicality of such techniques in general dentistry is not without limitations.

연구배경: 본 연구는 일부 대학에서 진행한 치위생 윤리 교과목을 통해 치위생(학)과 학생의 윤리적 의식과 윤리적 의사결정 역량을 달성할 수 있을지에 대한 학습성과를 평가하였다. 연구방법: 2021학년도와 2022학년도 1학기 G대학교 치위생학과 4학년 각각 35명, 29명과 D대학교 치위생과 3학년 각각 53명, 43명 총 160명을 대상으로 치위생윤리 교과목을 운영하여 수업운영 성과를 도덕적 민감성, 윤리적 의사결정을 할 때 자신감, 수업의 실제성, 학습성과, 수업만족도로 평가하였다. 각 평가항목은 Independent T-test와 Paired T-test를 하였으며, 통계적 유의수준은 0.05로 하였다. 연구결과: 양 대학 모두 수업 후 도덕적 민감성, 윤리적 의사결정을 할 때 자신감이 상승하였다(p<0.001). 치위생 윤리 교과목에 대한 수업의 실제성과 수업만족도는 학제 간 차이가 없었으며 4점 이상으로 긍정적으로 평가되었다(p>0.05). 학습성과는 4년제 학생들이 3년제 학생들보다 더 높게 나타났다(p<0.001). 결론: 치위생윤리 교과목을 통해 학생들의 도덕적 민감성과 치위생 윤리적 문제해결에 대한 자신감 등 윤리적 의사결정에 대한 역량을 강화할 수 있다고 평가되었다.

본 연구에서는 일반 칫솔과 씹는 칫솔의 치면세균막 제거효과를 비교하고 이를 통해 현재 출시된 씹는 칫솔이 일반 칫솔의 대용품으로 사용할만한 실용성을 갖추고 있는지와 실생활에서의 활용도 여부 등을 알아보고자 하였다. 연구 대상자는 전신 질환이 없으며 잔존치아 16개 이상 존재하는 구강상태가 양호한 20대의 건강한 성인 30명을 대상으로 하였으며, 일반칫솔과 씹는 칫솔 사용 후 치면세균막지수 감소율을 계산하였다. 일반 칫솔과 씹는 칫솔의 사용 전 후 치면세균막 감소효과를 비교한 결과, 일반 칫솔의 경우 PHP index는 7.02에서 1.91로 감소하여 치면세균막이 72.79% 감소한 결과를 나타내었으며, 씹는 칫솔은 6.72에서 4.08로 감소하여 치면세균막이 39.29% 감소한 결과를 나타내었다. 현재 국내에서는 다양한 구강관리용품이 출시되어 판매되고 있으며 일반인들의 올바른 구강관리용품 선택을 위하여 구강관리용품에 대한 다양한 연구가 필요할 것으로 생각된다.

Objectives: The purpose of this study was to establish a relationship among oral health perception, practicality, and the health-promoting lifestyle profile (HPLP) of soldiers, to finalize the oral health education content to be offered to military personnel under military service and explore remedial measures. Methods: The subjects included military soldiers older than 19 years of age in the Chungnam province. The study instrument was a structured questionnaire evaluating the general characteristics, HPLP, oral health perception, and oral health practice. Data were analyzed using one way analysis of variance (ANOVA), Kruskal-Wallis ANOVA, Pearson correlation, and multiple regression analysis. Results: The HPLP evaluation of the soldiers was 3.39, and the group with the higher HPLP level showed better oral health recognition and oral health practice, with a statistically significant difference. There were differences in oral health perception, tooth brushing practice, and oral health education interest depending on the level of education and stratum of the soldier. The higher the soldier's HPLP, the higher were the oral health perception and oral health practice. The factors affecting the HPLP were oral health perception, tooth brushing practice, and interest in oral health education. Conclusions: After the military discharge, it is necessary to devise ways that will enhance oral health perception and practices that promote good oral health and lifestyle.

Objectives: The purpose of this study is to verify the usefulness and practicality of the program in the daily life of the elderly by performing a three-dimensional tongue muscle exercise for the elderly to identify the dysphagia, swallowing ability, and tongue pressure. Methods: The subjects of the study were 29 elderly people aged 65 or older living in Busan, divided into a oral exercises group and tongue strength training program combined with oral exercises group, and operated 16 times for 8 weeks twice a week, and the pre and post-program evaluation was conducted in the 1st and 8th weeks. For variable selection, 7 general characteristics, 5 oral health-related characteristics, 5 Likert scale for swallowing disorder, repetitive swallowing ability test for swallowing power measurement, and tongue pressure measurement was used. Data analysis was conducted using SPSS window program 25.0 version (IBM), general characteristics and homogeneity tests, oral health-related characteristics and homogeneity tests were chi-square test, swallowing disorder, swallowing ability, and change in tongue pressure were paired t-test, Wilcoxon signed rank test, t-test, Mann-Whitney U test for swallowing disorder and changes in swallowing ability and tongue pressure, and Spearman's correlation for the relationship between swallowing disorder and swallowing ability and tongue pressure. Results: As a result of tongue strength training program combined with oral exercise, both relieve swallowing disorder and improve low eating and tongue pressure than oral exercise, and the difference in improvement effects of both relieve swallowing disorder, swallowing ability, and tongue pressure is higher. Conclusions: Based on the results of this study, it is believed that simple and practical oral muscle function reinforcement products and practical use are needed, and institutional devices to seek oral health promotion programs for the elderly are needed.
