Title Hypovitaminosis D is a Risk Factor for Periodontal Disease
Clinical Question Is periodontal disease (PD) linked to low serum 25-hydroxyvitamin D [25(OH)D]?
Clinical Bottom Line Evidence shows that there is an association of periodontal disease with low serum 25-hydroxyvitamin D. This is supported by evidence from a cohort study of calcium and vitamin D supplementation and another study that measured periodontal attachment loss as a function of serum 25(OH)D concentrations among different age groups.

#1) 19722793Miley/2009Cohort study involving 51 subjects Cohort study
Key resultsThe cohort study of 51 subjects, 23 taking vitamin D and calcium supplementation and 28 not taking such supplementation, was evaluated after 18 months. The study provided evidence for the association of periodontal disease (PD) with low serum 25(OH)D concentrations, indicating that subjects who took supplementation had shallower probing depths, fewer bleeding sites, lower gingival index values, fewer furcation involvements, less attachment loss ,and less alveolar crest height loss. Mean values of vitamin D and calcium intake for takers were significantly higher than non-takers for at least 18 months (1,049 IU/d and 1,769 mg/d in takers and 156 IU/d and 642 mg/d in non-takers). Measures of PD were consistently higher in non-takers than in takers (p <0.05) upon receiving periodontal maintenance therapy.
#2) 15213036Dietrich/2004Survey involving 11,202 subjectsSurvey
Key resultsData involving periodontal attachment loss and serum 25(OH)D concentrations were analyzed among subjects of two age groups, 20-49 years and >50 years. There were no significant trends in those 20-49 years old, but for those >50 years standardized b-coefficients varied from 0.39 (in males) and 0.26 (in females) for 25(OH)D <40.2 nmol/L to 1.0 (reference) for 25(OH)D >85.6 nmol/L. These results were adjusted for many factors, such as age, gender, ethnicity, smoking, diabetes, income ratio, body mass index, and gingival bleeding, and results suggested a strong association of PD with poor vitamin D status.

Comments on
The Evidence
Validity: Evidence in the first reference was recorded after 18 months. Results over a longer term could add validity to suggest that periodontal maintenance therapy was more efficient in supplement takers. Perspective: The cohort study and survey provides consistent evidence to show that there is an association of periodontal disease with low serum vitamin D, but further evidence, possibly from a long-term cohort study, is needed to support supplementation.
Applicability Though there are more commonly recognized risk factors for periodontal disease, such as age, diet, and smoking, evidence also supports hypovitaminosis D as a risk factor for PD. In patients with low serum 25(OH)D, supplementation, in addition to other factors, can be suggested to lower risk of PD.
