A possible correlation between periodontal disease and systemic diseases: a clinical study

Background: Periodontal disease (PD) is a widespread inflammatory condition with potential systemic implications. Its association with diseases such as diabetes, cardiovascular conditions, and hypovitaminosis D suggests a complex interplay involving immune-inflammatory mechanisms. To evaluate the correlation between PD and systemic biomarkers—blood glucose, glycated hemoglobin, cholesterol, vitamin D, and TSH, promoting awareness of the importance of regular health checkups. Methods: Eighty patients underwent periodontal evaluation and blood testing. Statistical analysis was used to explore associations between PD and systemic alterations. Results: PD was significantly associated with higher glycemia (p < 0.05), and linked to altered cholesterol and vitamin D levels, and increasing age. TSH levels showed a trend toward lower levels in PD patients, warranting further investigation. Conclusions: This study supports a possible bidirectional relationship between PD and systemic health. Findings suggest PD may contribute to increased risk of conditions like diabetes and atherosclerosis. The observed link with systemic biomarkers highlights the need for integrated diagnostic and preventive strategies. Future research with larger, more diverse populations is essential to validate these associations and to explore the impact of treating systemic conditions on periodontal outcomes.
