RESUMO
Periodontal inflammation is associated with systemic disease. Low-grade inflammation (LGI) is critical to the link between periodontal disease and several systemic disorders. C-reactive protein (CRP) is a common circulating biomarker for acute-phase immune responses, and it is closely related to LGI. The present case demonstrated excellent results using a comprehensive approach for periodontitis in a young woman with severe periodontitis and mild CRP elevation. A 21-year-old Japanese woman complained of tooth mobility and bleeding during tooth brushing. She was pre-obese (body mass index = 29.9), and she had a mildly elevated CRP level (5.2 mg/L). Of all periodontal sites, 34.5% had deep pockets (≥6 mm). The patient was diagnosed with stage III, grade C periodontitis and generalized aggressive periodontitis. Comprehensive periodontal treatments, including regenerative procedures for vertical bone loss and furcation involvement, were performed. Periodontal tissue inflammation was resolved, and periodontal regeneration was achieved. During the 2-year follow-up period, her teeth did not exhibit any signs of instability, attachment loss, or bone loss. Despite the weak nature of the evidence, this case suggests that CRP is valuable for assessing LGI, and it may potentially be considered during periodontal grading in the future.
