Analyzing The Patient-Provider Relationship And Assessing Shortages In Oral Healthcare In Arenac County, Michigan, Aaron Norfleet
Honors Projects
The purpose of this prospective study will be to assess the patient-provider relationship in Arenac County, Michigan, analyze barriers to treatment for rural patients, and develop a meaningful plan to improve upon these categories. The intended outcomes of this study will be the development of a resource for rural oral healthcare providers to better understand and treat the needs of their patients based on knowledge from beyond the chairside, as well as the development of an easily repeatable model for patient-provider analysis. Furthermore, the questionnaires and data collected from this could assist in informing governmental or non-governmental organizations in identifying …
Exploring Melatonin As A Treatment For Oral Ulcers, William H. Sutherland
Exploring Melatonin As A Treatment For Oral Ulcers, William H. Sutherland
Undergraduate Honors Theses
The hormone melatonin is best known for its role in the sleep-wake cycle, but its anti-inflammatory and antioxidant effects have significant implications that have not been fully explored in oral health. Some studies use melatonin to treat gastrointestinal ulcers, including duodenal ulcers and oral mucositis, but we found no study reporting its effects on more common oral ulcers, like aphthous stomatitis. We hypothesize that the anti-inflammatory and antioxidant characteristics of melatonin could effectively prevent and heal oral ulcers. In this paper, we review the literature on melatonin to propose its use as a treatment for oral ulcers. We also include …
