Oral diseases and dental health
Cigarette smoking and use of other tobacco products cause oral and dental diseases, including gum diseases, bone loss and cancers of the mouth and throat. Oral cancer risk for smokers and smokeless tobacco users is substantially higher compared to non-smokers.
This priority area will support research on early detection, prevention and treatment of tobacco-related oral diseases. Oral diseases in commercial tobacco product users are preventable in many cases, but advances in early-stage basic research are still lacking to inform treatment.
The 2014 Surgeon General’s Report “The Health Consequences of Smoking – 50 Years of Progress” listed the evidence as suggestive but not sufficient to infer a causal relationship between dental caries (cavities) and active cigarette smoking. In addition, the pathways from tobacco use (combusted or vaporized) to oral disease initiation, progression and prognosis are less clear.
The National Academies of Sciences, Engineering and Medicine recently published a consensus study report reviewing the available evidence of the health effects related to the use of e-cigarettes and identifying gaps and opportunities for future research. This report states that “there is limited evidence suggesting that nicotine- and non-nicotine–containing e-cigarette aerosol can adversely affect cell viability and cause cell damage of oral tissue in non-smokers.” Thus, California-based researchers are invited to explore innovative fronts in research on combustible and new and emerging tobacco product-induced oral disease.
According to the 2017 report “Status of Oral Health in California,” significant health disparities exist for oral diseases. African American men are more likely to die from oral cancer than non-Hispanic white males, partly because their cancers are diagnosed at a later stage. In addition, rural areas of California generally have higher incidence and mortality rates for oral cancer. Research into diagnostic screening tools that are accessible to priority groups is urgently needed.
Building the health workforce to address oral diseases and dental health is also a priority for TRDRP. Research that addresses health disparities, fosters partnerships to conduct effective prevention and treatment interventions for oral diseases in California’s diverse communities is also highly encouraged. Translational science to speed discovery from the bench to the community clinic to prevent oral disease and improve outcomes is an additional focus.
