Evaluation of correlation between serumic Vitamin D3 level and jaws bone density in posterior edentulous area of candidates for dental implants

Abstract

Background: only a few information exists about the role of Vitamin D on jaws’ bone density, and the number of human studies is scarce. Vitamin D deficiency is considered to diminish bone regeneration, and raising the serum level might take months. Hence, the primary aim of this study is to determine whether the vitamin D level in the chosen candidates is related to their jaw bone density. Methods: In the period of 6 months, 50 candidates for dental implants with the ages of 20 to 60 have randomly chosen at implantology department of Tabriz dental faculty. 15 of which were males and 35 females, and They were examined for their vitamin D3 level in the same specific laboratory. As the patients were registered to get implants, all of them already had their cone beam computed tomography (CBCT) radiographic images taken from same CBCT system before the procedure. They were divided into 3 groups based on their Vit D3 level; deficient, insufficient, and sufficient and their bone density at posterior edentulous areas were evaluated using mean calculated Hounsfield unit from the same software called Planeca Romexis. Result: Although in the mandibles of both males and females the minimum bone density was found in the vitamin D3 deficient group, but neither in maxilla nor mandible there was not any significant statistical relationship between vitamin D3 level and bone density. Conclusion: This study was unable to find an effective link between low serum levels of vitamin D3 and jaws’ bone density. Further studies should be taken to investigate this topic.
