association of periodontitis with white blood cell and platelet count: a cross-sectional study

Background and aim: inflammatory diseases can lead to reactive thrombocytosis, an increase in platelet count associated with cardiovascular risks. periodontal disease has been linked to systemic inflammatory responses. this study aimed to investigate the relationship between periodontitis and platelet and white blood cell (wbc) counts.materials and methods: this cross-sectional study included 630 participants from a health monitoring program. periodontal status was assessed using the community periodontal index of treatment needs (cpitn) and periodontal pocket depth (ppd) with a williams probe. blood parameters, including wbc and platelet counts, were measured using a complete blood count (cbc) test. statistical analysis was performed using spss (version 22), with a significance level of 5%.results: the participants included 360 women (57.1%) and 270 men (42.9%), with a mean age of 43.41 ± 7.01 years. no significant difference was observed in wbc counts among healthy individuals and those with mild or severe periodontitis (p = 0.774). however, there was a significant difference in the gingival index (gi) between the three groups (p < 0.001). wbc count was positively correlated with platelet count (p < 0.001) but not with cpitn. additionally, gi and cpitn showed a significant positive correlation (p < 0.001).conclusion: this study found no significant association between periodontitis and wbc or platelet counts, suggesting that periodontitis may not have a direct impact on these hematologic parameters.
