Figure 2. Genotypes did not affect on the structure of normal periapical tissue.

Figure 2

Panels are representative histology of normal (non-infected) periapical tissue in wild-type C57BL/6J, TLR2 KO and TLR2/TLR4 dKO mice. The original magnification was ×100. Polygonal orange and green lines outline the margin of dental root and alveolar bone, respectively. The area lying between these two lines is normal periodontal ligament tissue, which anchors tooth in alveolar bone. The structure of periapical region in non-infected animals was similar in all genotypes, and no visible differences were observed. AB: alveolar bone, R: dental root.
