Introduction: Oral health is often viewed as a significant component for an indication of good general health or for good well-being together with a decent quality of life. Health literacy is considered a crucial factor in improvising a good life or excellent health. Oral health literacy (OHL) is the ability necessary for people to identify the factors that lead to poor oral health, learn and put into practice the essentials of effective oral self-care behaviors, and communicate with oral healthcare professionals in order to schedule appointments, put their names on waiting lists for dental care, and locate the dentist's office. Aim and objectives: To evaluate students' oral health, their OHL, to determine the relationship between their oral health status and OHL, and finally to suggest preventive measures for the benefit of public health. Materials and method: At Teerthanker Mahaveer University, a cross-sectional study involving 1500 participants, ages 18 to 25, was conducted on students studying nursing, physiotherapy, paramedicine, engineering, and law. Their informed consent was obtained. The Rapid Estimate of Adult Literacy in Dentistry (REALD-99) was used to gauge OHL levels, and the WHO's 1997 Oral Health Survey was used for their clinical evaluation. Results: The mean REALD score was significantly higher in nursing students (88.32±6.46), followed by physiotherapy college (82.46±9.11), paramedical college (70.54±10.95), law college (46.52±7.74), and least in engineering college (38.80±10.65). The difference in the REALD score based on college was statistically significant. Along with this, the REALD score showed a correlation with gender and location too. Except for fluorosis, all the clinical parameters of dental caries, gingival bleeding, and pockets, loss of attachment, dental fluorosis, and dental enamel were associated with OHL. Conclusion: The results of the current study showed a relationship between educational attainment, clinical parameters examined, and OHL, leading to the conclusion that higher OHL is related to better oral health. So, we can conclude that maintaining good oral health requires OHL.

Dental insurance is a type of insurance policy that provides financial coverage for dental care expenses. Dental insurance plans may cover a range of dental care services. With dental procedures becoming increasingly expensive, having dental insurance can provide financial security and peace of mind. Dental insurance plans are available in India for individuals, families, and groups, and it is important to carefully review the coverage offered, premiums and deductibles, exclusions, and the reputation of the insurance provider when choosing a plan. In addition, the article explains the claim process and the premiums associated with dental insurance plans. It highlights the importance of regular dental check-ups and provides tips for maintaining good oral health to reduce the need for expensive dental procedures. Finally, the article answers some frequently asked questions about dental insurance in India. Overall, this article aims to educate readers about the importance of dental insurance and to provide practical advice for choosing and using dental insurance to cover the costs of dental care in India.

Synthetic dyes cause hazardous health-related problems in humans and affect the biological system underwater. They also have a negative impact on the nutritive value of soils and thereby on crops. Until now there is no effective method to remove the harmful component of dyes from the environment. However, the integrated treatment using bio agents with implication of physical and chemical processes can be effective in the treatment of dye effluents. From the complex azo dyes to their dissociation via thallophytes is a new scope for sustenance. Various studies have supported that laccases have the capability to degrade synthetic dyes that have different chemical structures. Thallophytes have been used to degrade the complex dyes with varying ranges of temperature and pH. Thallophytes have recently been used to treat the textile effluents with effective higher temperature and alkaline pH with decreasing BOD and thus cleaning them from environment in an eco-friendly and cost-efficient manner.

Quorum quenching is the process that prevents quorum sensing through the disruption of signalling cascade and bacterial communication among themselves mediated by the degradation of the signalling molecules. Therefore, quorum quenching has a considerable contribution in the negative regulation of threatening diseases and eventually increasing soil reclamation through different mechanism mediated by microorganisms in reclamation of soil. Quorum sensing has a significant contribution in enhancement of soil quality through microbial-based enzymes and mechanism in the versatile fields which are a component of the environment. The current chapter discusses the details of various direct and indirect mechanisms mediated by microbial systems that have a significant role in soil reclamation for the sustenance of the environment.
