FAP and periodontitis: Intriguingly, periodontitis is characterized by a significantly increased uptake of [68Ga] Ga‐FAPI‐04 compared to normal physiological uptake, with uptake levels surpassing those of 18F‐FDG (mean SUVmax: FAPI: 3.7 ± 0.9 versus FDG: 2.8 ± 0.3, n = 33).[17] These findings provide a strong theoretical basis for designing FAP‐targeting diagnostic molecules and therapeutic agents for periodontitis.
