    Poor oral hygiene may be linked to cancer

    There is no doubt that good oral hygiene is important; if dental plaque build up is left for a long time, it can lead to periodontal disease and tooth loss. This long-running cohort study suggests that poor oral hygiene during our 30s is associated with an increased risk of dying of cancer over nearly a quarter of a century.

    This study cannot prove that dental plaque levels either directly or indirectly cause c...

    Low serum 25-hydroxyvitamin D concentrations may explain the association between dental plaque and cancer mortality

    The finding that dental plaque is directly associated with 1.79 times the odds ratio of cancer mortality rates [1] is interesting. However, the conclusion that the bacterial load on tooth surfaces and gingival pockets may play a role in carcinogenesis is most likely incorrect. It is not clear how oral bacteria would cause cancer.

    An alternative explanation for the association is that high dental plaque is a mar...
