Dentin Hypersensitivity: A Literature Review
No full textDentin hypersensitivity is characterized by brief, intense pain triggered by external stimuli that affect exposed dentin with open tubules. The condition is primarily caused by two factors: the exposure and loss of dentin and the opening of dentin tubules, which allows sensory signals from the pulp to be transmitted in response to stimulation of the dentin surface. A precise diagnosis is crucial before initiating treatment and begins with a thorough patient medical history and clinical examination. Various treatment options have been developed to manage sensitivity, focusing primarily on nerve desensitization and the closure of open dentinal tubules. Developing a better understanding of the causes and mechanisms of dentin hypersensitivity is essential for effective prevention and treatment strategies for patients suffering from this condition. This review aims to provide dental professionals with comprehensive knowledge about dentin hypersensitivity, including its causes, diagnostic procedures, clinical management techniques, and innovative methods for reducing sensitivity
Challenges and Opportunities in Using Social Media to Build Digital Literacy in Public Education: A Review-Based Perspective
No full textThe advancement of technology that continues to develop today can help accelerate and simplify human work. Technological progress facilitates communication without limitations of space and time. Easy internet access makes it easier to obtain various types of information. However, the vast amount of information available online can also lead to the spread of hoaxes and misinformation. This makes digital literacy crucial for the public to distinguish between valid and invalid information. Social media, as an easily accessible form of information technology, can serve as an educational medium for promoting digital literacy. Social media as a model for digital literacy can also be applied in science education by providing students with worksheets and asking them to review information found on social media related to specific science topics. This approach not only strengthens students’ digital literacy skills but also deepens their understanding of scientific concepts by connecting them with real-world issues and current information trends. The method used is descriptive qualitative, with data derived from previous research conducted over the past ten years. The results show that digital literacy is essential for communities in utilizing technology effectively. A high level of digital literacy enables individuals to differentiate between accurate and inaccurate information. The opportunities for using social media in digital literacy education include enhanced collaborative communication, engagement and accessibility, empowerment, lifelong learning, and the promotion of innovative educational practices. The challenges, however, include limited access and resource constraints, barriers to digital literacy, privacy and security concerns, and ethical and professional considerations. These findings support the strategic integration of social media into public education systems as a tool to enhance both scientific and digital literacy, especially among yout
Integrating Sandur Madura as a Cultural Context in Science Education: An Ethnographic Study on Migration and Acculturation in West Kalimantan
No full textImmigration by Madurese natives in West Java was carried out due to economic and geographical factors and supported by an independent, dynamic, and courageous nature. This economic factor is indicated by the still high poverty rate in East Java and the high level of competition in getting jobs. Migration is an option for Madurese people to find sources of life that are starting to be limited; one of the migration destinations is in West Kalimantan. Many Madurese people migrate to West Kalimantan because they already have relatives there and have opportunities to improve their economy. This migration certainly affects the culture of the community, where Madura has a culture that must be maintained by its people even though they are outside the Madura area; the goal is to preserve and maintain the culture. Sandur is one of the Madurese cultures in the form of a theatre performance that integrates music, dance, and acrobatic silat movements. Education is one of the keys to preserving Madurese culture for immigrant communities in West Kalimantan. The method used is a qualitative ethnographic approach through observation and structured in-depth interviews to understand the dynamics and interactions of the Madurese ethnic group with local ethnic groups. The results of the study show that the Sandur performing arts not only function as entertainment, but also as a means of social education that conveys moral and ethical values, a bridge of acculturation. The process of enculturation and acculturation creates cultural harmony that enriches the identities of both parties, marked by the modernization of Sandur in its performances to adapt to local culture in West Kalimantan. The existence of a curriculum that supports Sandur culture can support students' sense of pride and active participation so that students will have awareness and participate in preserving Sandur culture. These findings support the integration of local cultural values into science education, fostering both scientific literacy and cultural identity among students
Secondary Metabolites and Antioxidant Properties of Lichens from Sicike-Cike Nature Park, North Sumatra
No full textThis study aimed to evaluate the phytochemical composition and antioxidant activity of five lichen species Cladonia portentosa, Cladonia rapii, Letharia vulpina, Parmotrema hypotropum, and Usnea trichodea collected from Sicike-Cike Nature Park, North Sumatra, Indonesia. Methanol extracts were prepared from dried and powdered lichen samples. Qualitative phytochemical screening using specific reagents identified the presence of alkaloids, flavonoids, tannins, saponins, terpenoids/steroids, and glycosides in varying levels among the species. Antioxidant activity was assessed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method, with IC50 values ranging from 42.3244 µg/mL to 86.7479 µg/mL. Parmotrema hypotropum demonstrated the strongest antioxidant activity (IC50 = 42.3244 µg/mL), categorized as moderate based on literature benchmarks. The strong activity is likely due to the presence of alkaloids, flavonoids, and saponins. In contrast, Usnea trichodea showed the weakest activity. These results suggest that certain lichens, especially Parmotrema hypotropum, may serve as promising sources of natural antioxidants. The findings support potential applications in pharmaceutical formulations and natural cosmetic products, particularly those targeting oxidative stress. Future studies should focus on isolating dominant compounds such as usnic acid or flavonoid derivatives and further exploring their bioactivity profiles
