Background: Oral cavity squamous cell carcinoma (SCC) arising in nonsmokers and nondrinkers remains poorly characterized. We hypothesized that these patients had prior exposure to metallic dental hardware. Methods: We utilized a questionnaire querying the lifetime oral health status of 54 patients. Demographics and extensive oral health history were collected. Results: The majority of patients (74%) had prior exposure to metallic dental hardware. The younger population with almost exclusively oral tongue cancer had a high prevalence of metallic orthodontic braces (40%) within 15 years before diagnosis. In the 51+ year age group, 82% had crowns, dental implants, and/or dentures with metallic elements. Conclusion: Exposure to metallic dental hardware has increased in the past few decades given the rise of orthodontic braces and older adults retaining more teeth. Although this study does not prove a causal relationship between oral cavity SCC and dental hardware, this is a step toward identifying and investigating their role.
