To assess the qualitative and semiquantitative levels of C-reactive protein in chronic periodontitis patients, 30 patients (15 males and 15 females) diagnosed with chronic periodontitis and ranging in age from 35 to 50 years were selected. They were divided into Control Group, Test Group A, and Test Group B. Pocket depth was measured using the UNC-15 periodontal probe, and the qualitative and semiquantitative levels of serum CRP were assessed using the CRP slide test based on the principle of agglutination by means of the RHELAX CRP kit. The mean CRP scores for the Control Group, Test Group A, and Test Group B were found to be 0.3, 0.57, and 3.60, respectively. The obtained value of 15.286 out of 7 was found to be significant at the 0.000 level. Quantitative analysis revealed the presence of agglutination in patients with increased severity of the disease subgroups, i.e. Test Group B and A. Semi-quantitative analysis revealed that the serum CRP level increased as the mean probing pocket depth increased. Treating periodontitis lowers CRP levels and possibly also reduces the risk of CHD." Overall, the suggested corrections include adding some punctuation marks, clarifying some sentence structures, and making sure the text is clear and easy to read.
