The research proposal is to investigate the relationship that exists between poor dental hygiene and the occurrence of cancer. Researchers are currently looking at a variety of factors including alcohol use, tobacco smoking and other bad habits and their impact on the occurrence of oral cancer. Poor oral hygiene is one of the most significant contributing factors to the development of this disease. However, there is a limited amount of research that focuses on the development of methods to prevent the development of the disease. In In particular, little attention is paid to the development of a strategy for educating the population and members of the community about this problem. As part of the study, I would like to see which population groups are most affected by this problem and how it is associated with poor dental hygiene. Based on the data obtained, I would like to make recommendations that could be applied by professional dental hygienists to increase community awareness of cancer prevention measures due to poor oral hygiene. This line of research is extremely significant because it uses theoretical knowledge to develop practical recommendations that can later be applied by professionals. Increasing public awareness of the possible negative consequences of dental hygiene can greatly contribute to the prevention of cancer. In turn, this aspect can result in a decrease in the number of cancer patients and a reduction in the resources needed for their treatment. The research hypothesis is that members of the most disadvantaged communities are most likely to develop oral cancer due to poor oral hygiene.
