The purpose of this study was to compare of the effectiveness by hydroxyapatite (HAp) and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) containing paste on bleached enamel. Seventy-two bovine enamel blocks were prepared and randomly divided into two groups: distilled water (D·W), 30% hydrogen peroxide. And thirty-six bleached enamel block were divided into three groups: Bleached enamel after distilled water, Bleached enamel after hydroxy apatite paste , Bleached enamel after CPP-ACP paste. The samples were analyzed qualitatively by evaluating morphological changes in the SEM images, microhardness and quantitatively by using roughness parameters (Ra). The acquired data was analyzed by paired t-test and one-way ANOVA followed by Tukey s multiple test for variable at a 0.05 significant level. All the samples showed decrease in the microhardness after two cycles of bleaching, though immediately after bleaching the decrease in the microhardness was significant (p<0.05). Bleached enamel surface of two remineralizing paste groups showed any apparent morphology and roughness changes compared to the enamel which was stored in distilled water only. HAp and CPP-ACP containing paste used in the study causes an increase in the microhardness of bleached enamel by maintaining a high gradient of calcium and phosphate ions at the enamel surface. HAp and CPP-ACP containing paste has the potential to remineralize on bleached enamel.

Objectives: It is to understand the personality characteristics of students through the results of MBTI personality type and major satisfaction of dental hygiene students and provide basic data for student guidance and counseling Methods: From December 4, 2003 to March 29, 2024, 305 students enrolled in the dental hygiene department were conducted. For the data analysis of this study, the SPSS version 27.0 (IBM Crop, Armonk, USA) statistical program was used. Results: 1. The distribution of individual preference indicators was more introverted (I), sensory (S), sensory (F), and cognitive (P) 2. The MBTI personality types appeared in the order of ISFP, ISTP, ISFJ, and INFP, ESTJ. 3. The personality type by function was the highest in the sensory (S)-emotional type (F), and the personality type by temperament was the highest in the sensory (S)-perception type (P) 4. In terms of major satisfaction according to preference trends, students in introversion (I), sensory (S), thinking (T), and judgment (J) had high major satisfaction, and major satisfaction by personality type was in the order of ESTP, ISTJ, ISFJ, and ESFP, and major satisfaction of ST by function and SJ by temperament was the highest. Conclusions: Through the above results, it is expected that the MBTI personality type of students will be actively utilized to provide basic data on student guidance and counseling for students who may not adapt to the department.

Objectives: The purpose of this study was to investigate the relationship between removable dentures, need, and generalized anxiety disorder in Korean adults. Methods: Using data from the 8th National Health and Nutrition Examination Survey (2021), 4,362 adults aged 40 or older were surveyed using SPSS 21.0. Results: The average score of the subjects' general anxiety disorder was 1.80 out of 3. In the maxillary prosthesis state, general anxiety was perceived higher in the partial denture than no prosthesis. In the necessity of mandibular removability, it was confirmed that the general anxiety disorder was perceived higher in the full denture than in the partial denture. Conclusions: Efforts should be made to promote and prevent oral health so that it is not included in the subjects who use removable dentures and experience general anxiety disorder.

악성 흑색종에서 CGM이 유도하는 세포자멸사와 상피간엽이행 억제 효과

강해미(Hae-Mi Kang),문성혁(Seong-Hyeok Moon),김인령(In-Ryoung Kim),박봉수(Bong-Soo Park) 한국구강보건과학회 2024 한국구강보건과학회지 Vol.12 No.2

Objectives: This study explored the effects of CGM treatment on malignant melanoma cells, specifically by focusing on its ability to induce apoptosis and alter the expression of proteins involved in epithelial-mesenchymal transition (EMT), a critical process in cancer metastasis. Methods: To assess cell viability and proliferation rates, at MTT assay and colony formation assay were performed. FACS analysis was conducted to confirm cell apoptosis, and JC-1 fluorescent staining was executed. An invasion assay was performed to observe cell invasiveness, and protein expression was validated by western blot analysis. Results: Our findings demonstrated that CGM treatment significantly induced apoptosis in malignant melanoma cells. Additionally, CGM treatment markedly reduced the invasiveness of melanoma cells, as observed in the invasion assays. Western blot analysis revealed that CGM modulated the expression of several critical proteins involved in EMT, thereby disrupting the EMT process which is essential for cancer metastasis. Conclusions: The research findings indicate that CGM inhibits the growth of melanoma effectively induces apoptosis of cancer cells, and suppresses metastasis through EMT inhibition. Therefore, CGM demonstrates significant value as a potential cancer therapeutic agent.

이지영(Ji-Young Lee),박미정(Mi-Jung Park) 한국구강보건과학회 2024 한국구강보건과학회지 Vol.12 No.2

Objectives: This study was conducted to determine the impact of several factors on dental hygiene students’ satisfaction with clinical practice. Methods: This study conducted via an online survey of 138 dental hygiene students from Gangwon, Gyeongnam, and Busan, South Korea, from October 31 to December 15, 2023. Results: The higher the self-esteem, the higher the self-directed learning ability, and the higher the self-directed learning ability, the higher the sense of belonging in clinical practice. The higher the sense of belonging in clinical practice, the higher the satisfaction with clinical practice. Factors influencing clinical practice satisfaction were found to be self-esteem and a sense of belonging to clinical practice. Conclusions: To increase satisfaction with practice, educational programs that improve self-esteem, increase self-directed learning opportunities, and cultivate a sense of belonging in clinical practice should be developed and utilized.
