Vitamin D is needed for uptake of calcium from the gut and reabsorption of calcium from the kidneys and bone to maintain adequate plasma calcium concentrations for bone mineralization. Many studies have investigated the association between vitamin D status and periodontal diseases. Recently, Third National Health and Nutrition Examination Survey (NHANES III, 19881994) reported that there was an inverse association between serum 25-hydroxyvitamin D concentrations and gingival inflammation and periodontal clinical attachment level. Maintenance of vitamin D intake near or above the recommendations, whether through diet or supplementation, could be a safe and effective way of reducing periodontal disease prevalence. People taking combined dietary supplements of vitamin D and calcium tended to have better periodontal health, with shallower probing depth, less attachment loss, and less alveolar bone loss. In tis case, a 44 year old female was referred for an opinion regarding a six-months history of progressive tooth loss. This case report shows that tooth loss might be seen in patients with D vitamin deficiency.
