Therapeutic Role of Vitamin D Supplementation in Periodontitis: A Case-Based Approach

Generalized periodontitis is a common chronic inflammatory disease that may be aggravated by systemic conditions such as vitamin D deficiency. This report describes a 43‑year‑old male who presented with bleeding gums, discomfort during chewing, and tooth mobility, with clinical and radiographic findings consistent with Stage III, Grade A generalized periodontitis. The management plan combined nonsurgical and surgical periodontal therapy with adjunctive vitamin D supplementation. On follow‑up, the patient showed marked improvements in clinical attachment and reduction in inflammation, underscoring the importance of assessing and addressing vitamin D status to optimize periodontal treatment outcomes even in populations where deficiency may be overlooked.
