Evaluation of the relationship between serum level of Vitamin D and decayed, missing, and filled teeth (DMFT) in young women in Semnan, Iran (2018–2019)

Abstract

Introduction: Previous studies have shown that Vitamin D has an effect on calcium absorption, mineralization, and dentin formation and also on the maturation and formation of developing teeth, but the aim of this study was to evaluate the relationship between serum level of Vitamin D and Decayed, Missing, and Filled Teeth (DMFT) in adult patients with developed teeth. Materials and Methods: In this descriptive, cross-sectional study, 200 women with the age range of 15–40 years who referred to the Semnan Dental School in 2018–2019 and satisfied the inclusion and exclusion criteria were selected randomly. Then, DMFT, Plaque Index (PI) and SI index, age, the history and recent Vitamin D deficiency, and the history of xerostomia in patients were studied and statistically analyzed. Results: Only 4 (2%) of the women had a DMFT index score of 10 and 78 (39%) had a score of 3 and 4, respectively. Most patients were aged 30 years and younger (64.5%) and most of them (90.5%) had no previous history of Vitamin D deficiency and only eight patients (4%) had xerostomia. More than half of the individuals (54%) had some degree of recent Vitamin D deficiency. More than half of the women had PI grade 3 (54%) and 82 individuals (41%) had high blood sugar levels. According to Spearman's results, there was a moderate and negative correlation between DMFT and Vitamin D levels. Conclusion: Therefore, the lower the level of Vitamin D, the higher the DMFT index by excluding other caries-causing factors. Consequently, it is recommended that this is considered in high-risk groups in order to prevent oral health problems.
