Ghalwash et al. [5] compared FGF23 in the non-CKD population and demonstrated a higher FGF23 level in the periodontitis group compared to the healthy population with a mean of 52.85 RU/mL versus 28.21 RU/mL, respectively, which decreased significantly following periodontal treatment. The gene discussed is FGF23; the disease is periodontitis.
