Input (English): Question: Do haplotypes of susceptibility to chronic periodontitis in the Interleukin 8 gene influence protein level in the gingival crevicular fluid?
Answer: The IL8 haplotype of susceptibility to CP was neither associated with IL-8 cytokine levels nor with clinical periodontal parameters. Also, CP, IL8 haplotype and IL-8 concentration showed a positive association with the GCF volume levels in the studied patients.
Output (English): no
