Background: Periodontitis is a prevalent chronic inflammatory disease affecting the supporting structures of teeth, leading to tooth loss and systemic health implications if left untreated. Accurate evaluation of disease severity and individualized risk assessment are critical for effective treatment planning and prognosis. Periodontal Risk Assessment (PRA) provides a structured framework for identifying patient-specific risk factors and predicting disease progression.

Objective: This study aimed to evaluate the severity of periodontal disease in patients with chronic periodontitis using the PRA tool and to examine the distribution of risk levels in a clinical population.

Methods: A cross-sectional study was conducted at a single institutional dental center. Adult patients diagnosed with chronic periodontitis were enrolled. Comprehensive periodontal examinations were performed, including measurements of probing depth, clinical attachment loss, bleeding on probing, and radiographic bone loss. PRA scores were calculated for each patient based on clinical parameters, systemic factors, and lifestyle-related risk determinants. Data were analyzed to correlate PRA-based risk levels with disease severity.

Results: The study included [insert number] patients, with a balanced representation of age and gender. The majority of patients exhibited moderate to severe periodontitis. PRA evaluation classified patients into low, moderate, and high-risk categories, with a significant proportion falling into the high-risk group. Higher PRA scores were strongly associated with increased clinical attachment loss, deeper probing depths, and greater radiographic bone loss, indicating a robust relationship between assessed risk and disease severity.
