Background: Dental implants are today considered a successful treatment for restoring function and aesthetics. Vitamin D plays a fundamental role in bone metabolism. Hence, the present study was undertaken for assessing the correlation between serum vitamin D levels and prognosis of dental implants. Materials & methods: A total of 50 patients were enrolled in the present study. Complete demographic data of all the patients was recorded. All the patients were broadly divided into two study groups. Group A consisting of 25 patients in which dental implant therapy was successful both clinical and radiographically on two years follow-up and Group B consisting of 25 patients in which dental implant therapy failed. Blood samples were obtained from all the patients and serum vitamin D levels were assessed. All the results were recorded in Microsoft excel sheet and were analyzed by SPSS software. Results: Mean vitamin D levels among patients in group A and group B was 56.11 ng/mL and 61.88 ng/mL respectively. Non-significant results were obtained while comparing the means serum vitamin D levels between patients of group A and group B. Conclusion: Our study failed to establish any relationship between serum vitamin D levels and prognosis of dental implants. Key words: Vitamin D, Dental implant
