On Thursday, 12 September 2024, third-semester students of the Dental Hygiene Study Program participated in an Oral Biology practicum with the theme Oral Cavity Epithelium Cytology at the Integrated DLC Laboratory, 4th floor. The activity was supervised by Dr. drg. Alma Linggar Jonarta, M.Kes., a lecturer from the Department of Oral Biology. Before starting the practicum, students were required to wear lab coats and take a pretest to assess their understanding of the material to be studied.
The purpose of this practicum was to help students understand and perform the procedure for preparing oral mucosal epithelial smear preparations. This allows them to observe epithelial cells under normal and pathological conditions. After preparation, students conducted microscopic observations of epithelial cell smears.
The tools and materials used in this practicum included: cytobrush, glass slides, glass cover slips, staining jars, microscopes, handy tally counters, distilled water, alcohol, and filter paper. The staining process utilized various solutions, including 1% acetic acid solution, Harris hematoxylin (60°), Orange G-6, EA-50, methanol, and xylene.
This practicum not only provided students with practical skills but also emphasized the importance of access to education in the field of biology. Engaging in hands-on experiences like this prepares students to understand complex biological concepts and their real-world applications. This aligns with the Sustainable Development Goals (SDGs), particularly Goal 4, which aims to ensure inclusive and quality education and promote lifelong learning opportunities for all.
As students prepared their samples, drg. Alma provided insights into the importance of epithelial cells in the oral cavity, discussing their role in health and disease. This interactive approach encouraged a deeper understanding, prompting students to ask questions and engage in discussions.
After the preparation phase, students observed their slides under the microscope, noting differences between normal and pathological epithelial cells. This hands-on experience reinforced the theoretical knowledge gained in lectures, highlighting the connection between theory and practice in biology.
Student feedback was overwhelmingly positive, with many expressing appreciation for the opportunity to apply their knowledge practically. They recognized that experiences like this are crucial for their academic and professional development, as well as for preparing them to enter the healthcare field.
The Oral Biology Practicum on Oral Cavity Epithelium Cytology not only enhanced students' practical skills but also emphasized the importance of access to quality education in science. By providing hands-on learning experiences, educational institutions contribute to achieving the SDGs, ensuring that future generations are equipped to tackle challenges in healthcare and biology.
