Associations between serum 25-hydroxyvitamin d and periodontal pocketing and gingival bleeding: results of a study in a non-smoking population in Finland.

Background: Apart from the effects of vitamin D on bone metabolism, it is also known for its immunomodulatory properties. However, so far, it is not clear whether serum 25-hydroxyvitamin D [25(OH)D] exerts any beneficial effect on the periodontium. The aim of the present study is to investigate whether the serum level of 25(OH)D is related to periodontal condition, measured by means of pocketing and gingival bleeding.
