Influence of Vitamin D Level on Oral Health Status in Adult Hypophosphatasia

Vitamin D deficiency is common in hypophosphatasia (HPP) patients. However, its impact on oral health is unclear. Therefore, the purpose of this study was to investigate the relationship between Vitamin D levels and oral health in adults with hypophosphatasia.

In this retrospective study, oral health and bone metabolism in HPP patients were examined. The Decayed/Missing/Filled Teeth (DMFT) index, clinical attachment level (CAL), probing pocket depth (PPD), and periodontal screening index (PSI) were among the metrics used to evaluate oral health.

The average age of the 48 HPP patients in the study was 42.21 (±15.78) years. A mean Vitamin D level of 29 μg/L was used to divide the participants into two groups. Compared to patients with Vitamin D levels above 29 μg/L, those with levels below this threshold showed noticeably worse oral health, as evidenced by higher PSI, PPD, decayed tooth count, and periodontitis severity index.

The results imply that adults with HPP who have low Vitamin D levels have worse oral health. To potentially improve oral health, it is crucial to diagnose and treat Vitamin D deficiency in HPP patients, as it is a known risk factor for periodontitis in the general population.
