Does Type D personality predict the onset of periodontal disease in healthy university students?
Type D personality and BMI ≥ 25 are significant predictors of periodontal disease onset in young adults over a 3-year period.
Answers are grounded in this paper and cite their sources.
Type D personality may elevate periodontal risk in young adults; hypothesis-generating and requires prospective validation before clinical use.
The purpose of this prospective cohort study was to investigate whether Type D personality was related to periodontal disease in Japanese university students. Among students ( n = 600) who were interested in receiving oral health examinations, logistic regression analysis showed that the risk of developing periodontal disease during a 3-year period was associated with body mass index ⩾ 25 (odds ratio: 2.543; 95% confidence interval: 1.297-4.989; p = 0.007) and Type D personality (odds ratio: 1.473; 95% confidence interval: 1.027-2.111; p = 0.035). In this short-term prospective cohort study, a significant association between periodontal disease and Type D personality was observed in Japanese university students.

Mizutani et al. (2016) conducted a cohort in Periodontal disease (n=600). Type D personality vs. Non-Type D personality was evaluated on Onset of periodontal disease during a 3-year period (OR 1.473, 95% CI 1.027-2.111, p=0.035). Type D personality was significantly associated with an increased risk of developing periodontal disease over a 3-year period in Japanese university students (OR 1.473).
