Outline of Final Research Achievements

Our aim was to investigate a prevalence of aggressive periodontitis (AgP) and the association between AgP and the Mediterranean diet in the Moroccan population. Olive oil consumption score (a component of MDS) was significantly and inversely associated with AgP (adjusted odds ratio = 0.55, 95% confidence interval = 0.32-0.96). The dietary pattern characterized by frequent consumption of olive oil may have a protective effect against AgP. Further longitudinal studies with data on serum fatty acid composition are required to substantiate our findings.

Academic Significance and Societal Importance of the Research Achievements

侵襲性歯周炎の原因および病態については従来から国内外で研究が行われてきたが、まれな疾患ということもあり十分はエビデンスが得られているとは言いがたい。
例えば、侵襲性歯周炎の有病率ひとつとっても公開に耐えうるデータも不十分というのが現状である。我々は10年ほど前からモロッコ王立大学の歯学部の歯周病科(Ennibi教授)研究室と共同研究を立ち上げてきており、本研究において新たな知見が得られたと考えている。
