[Effects of essential periodontal treatment on serum level of sCD40L and periodontal clinical parameters in patients with moderate to severe periodontitis at high risk of stroke].

PURPOSE

To investigate the effect of periodontal treatment on patients with moderate to severe periodontitis at high risk of stroke, by detecting the level of serum soluble cell differentiation antigen 40 ligand (sCD40L) before and after periodontal non-surgical treatment.

METHODS

Seventy-six patients with moderate to severe periodontitis at high risk of stroke were collected and randomly divided into 2 groups, 40 patients in group A received essential periodontal treatment + routine maintenance therapy, 36 cases in group B only received routine maintenance therapy. Another 36 patients with moderate and severe periodontitis were selected as group C, and received essential periodontal treatment. Bleeding on probing (BOP), periodontal probing depth (PD) and attachment loss (AL) in 6 loci were examined by the same dentists, and enzyme linked immunosorbent assay (ELISA) was used to detect the level of serum sCD40L before treatment and 3 months after treatment. The data were analyzed by SPSS 17.0 software package.

RESULTS

Compared with pre-treatment, serum level of sCD40L and periodontal clinical indexes of the three groups decreased. Compared with group B, serum SCD40L in group A significantly decreased(P<0.05).

CONCLUSIONS

Periodontal treatment can reduce the serum level of sCD40L in patients with moderate to severe periodontitis at high risk of stroke, and improve the patient's inflammatory state. To a certain extent, periodontal treatment may reduce the risk of high-risk stroke population to develop stroke.
