Background & Objectives Adherence to the Mediterranean diet (MedDiet) has been reported to be associated with a lower risk of various chronic diseases. This cross‐sectional study aimed to investigate the potential association between adherence to the MedDiet and periodontitis, which is highly prevalent in young Moroccan individuals. Methods We evaluated 1075 Moroccan individuals (72% women, mean [standard deviation] age = 20.2 [1.5] years). Adherence to the MedDiet was assessed using the MedDiet score (MDS) based on the frequency of intake of eight food groups (vegetables, legumes, fruits, cereals or potatoes, fish, red meat, dairy products, and olive oil). A value of 0 (unhealthy) or 1 (healthy) was assigned to each food group, and the MDS (range, 0‐8 points) was generated by adding the individual scores, with a higher score indicating better adherence to the MedDiet. The logistic regression model was used to evaluate the MDS (high [5‐8 points]/low [0‐4 points]) and each component score (1/0) with the presence of periodontitis, which was determined through full‐mouth periodontal examinations. Age, sex, and oral health behavior were considered as potential confounders. Results In total, 693 (64.5%) study participants showed high MDSs. Periodontitis was observed in 71 (6.6%) participants. No significant association between MDS and periodontitis was observed. Nonetheless, olive oil consumption, a component of the MDS, showed a significant inverse association with periodontitis (adjusted odds ratio = 0.55; 95% confidence interval, 0.32‐0.96). Conclusions The MedDiet was not significantly associated with periodontitis among young Moroccans. However, frequent consumption of olive oil may have a protective effect against periodontitis, although the temporal association needs to be clarified in further studies.
