Reflecting its multidisciplinary character, the Dunedin Study is the only study in the world to have collected data on the same individuals’ oral health from age 5 continuously through to mid-life. Capitalising on this unique data, Murray Thomson led a study that appeared in the Journal of the American Medical Association (JAMA) identifying cannabis use as a novel risk factor for periodontal disease [96]. At the time, it was one of only two oral health research papers to have appeared in this prestigious general medical journal in the previous 20 years. Another, more recent oral health paper addressed the fluoride-IQ debate, generating a deal of interest among researchers and the wider community [97].
