Table 2 shows the median values for the periodontally healthy group 0.654 ng/mL and the periodontitis group 0.965 ng/mL. Moreover, it indicates the 25th to 75th percentiles for the periodontally healthy group range 0.644–0.827 ng/mL and the periodontitis group range 0.886–1.165 ng/mL. The difference in AMCase levels between the periodontally healthy and periodontitis groups were statistically significant (p < 0.05) by Student’s t-test. Here, CHIA is linked to periodontitis.
