TRPC6 and TRPC3 expression during periodontitis progression. A Representative images on day 28 and TRPC6 expression (control group; D7 n = 5, D14 n = 5, D28 n = 4, and periodontitis group; D7 n = 3, D14 n = 3, D28 n = 5). Black arrowheads indicate representative TRPC3-positive osteoblasts. B Representative images on day 28 and TRPC3  expression (control group; D7 n = 5, D14 n = 5, D28 n = 5, and periodontitis group; D7 n = 5, D14 n = 8, D28 n = 8). Black arrowheads indicate representative TRPC6-positive osteoblasts. Scale bar = 50 μm. Data are presented as the mean ± SE. *p < 0.05 versus control. No, number; PDL, periodontal ligament; TRPC, transient receptor potential canonical
