Exploring the link between apical periodontitis and diabetes through inflammatory markers

Association of Apical Periodontitis With Systemic Level of Inflammatory Markers : A Longitudinal Intervention Study

Not applicable Interventional Postgraduate Institute of Dental Sciences Rohtak · NCT05814965

This study is testing how apical periodontitis might affect people with type 2 diabetes by looking at inflammation levels before and after root canal treatment.

What this trial studies

This longitudinal interventional study aims to investigate the cause-and-effect relationship between apical periodontitis (AP) and type 2 diabetes mellitus (DM) by assessing systemic inflammatory markers. A total of 280 patients with radiographic evidence of AP will be recruited and divided into two groups: those with type 2 DM and those without systemic disease. Each group will further consist of patients with AP and matched controls. The study will evaluate periapical healing and changes in inflammatory markers following root canal treatment over a 12-month period.

Who should consider this trial

Good fit: Ideal candidates are adults aged 30-55 with at least 20 natural teeth and radiographic evidence of apical periodontitis.

Not a fit: Patients with moderate to severe periodontitis, immunosuppression, or other significant medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the management of dental health in diabetic patients, potentially improving treatment outcomes.

How similar studies have performed: While there have been cross-sectional studies on this topic, this prospective interventional approach is novel and has not been extensively tested.
