Periodontal diseaseExposure to sunlight

There are no reports in the journal literature of a link between solar ultraviolet-B (UVB) irradiance and Periodontal disease (PD).  

However, there are at least two papers in the literature reporting prevalence of dental caries in the United States with respect to geographical location in which the strongest correlation is with reduction in solar UVB1 and one in Australia2.  

Dental caries is analogous to Periodontal disease (PD) in that it is caused by oral bacteria3.  These three studies are discussed in the document on dental caries.
