Is yogurt intake associated with periodontitis due to calcium?

Abstract

The purpose of this study is to determine whether the lower intakes of yogurt, milk, and calcium are associated with periodontitis in a nationally representative sample of Korean adults. This study comprised 6,150 adults 19 or more years old who took both periodontal examination and nutrition survey. The frequency of yogurt and milk intake was examined with a food frequency questionnaire. The amount of calcium intake was calculated with dietary intakes data gained from complete one-day 24-hour recall interviews. Periodontitis was assessed using the Community Periodontal Index (CPI). Multivariate logistic regression analyses were performed for the whole sample and subgroups with the strata of age, gender, or smoking, in a complex sampling design. Less intake of yogurt was significantly associated with periodontitis (odds ratio [OR] 0.82, 95% confidential interval [CI] 0.70–0.97), but neither less intake of milk (OR 1.04, 95% CI 0.89–1.20) nor lower intake of calcium (OR 1.04, 95% CI 0.89–1.21) was significantly associated with periodontitis. In the subgroup analysis, no difference in the association of yogurt intake with periodontitis was found according to the strata of age, gender, and smoking. In conclusion, periodonitis was significantly associated with the less intake of yogurt among the Korean adults, but the calcium contained in yogurt is not likely to cause it.

The anti-inflammatory effect of milk and dairy products on periodontal cells: an in vitro approach

“…Even though in vitro, milk, fermented milk products, and powdered milk possess a potent antiinflammatory effect, as to whether this observation can be applied to patients suffering from oral mucositis is questionable. Epidemiological research into the association between the intake of yoghurt and the incidence of periodontitis, in a nationally representative sample of Korean adults, conflicts with this proposition [37]. Recent systematic reviews on the protective effect of breastfeeding with respect to malocclusion and caries raise a possible role of milk in oral health, but not with a focus on inflammation [38].…”

Interspecies Inhibition of Porphyromonas gingivalis by Yogurt-Derived Lactobacillus delbrueckii Requires Active Pyruvate Oxidase

“…Lactobacillus gasseri and Lactobacillus rhamnosus GG treatment reduce alveolar bone loss in mouse models of periodontitis (18,19). These results are perhaps unsurprising given several studies demonstrating that individuals who consume more fermented dairy products like yogurt and kefir (which contain Lactobacillus species) have a lowered incidence of periodontal disease and/or decreased severity of disease (20,21). One of the main Lactobacillus species found in fermented dairy products is Lactobacillus delbrueckii.…”

Association between semi-solid yogurt intake and periodontitis in Korean adults

“…However, Shimazaki et al [12] reported that calcium intake from dairy products may not have a major impact on periodontal disease and that among various dairy products, only intake of lactic acid-containing foods such as yogurt was associated with periodontitis. Kim et al [33] also inferred that the calcium contained in yogurt is not associated with a decreased prevalence of periodontitis. Therefore, this study focused on the lactic acid bacteria component of yogurt, not calcium.…”
