Figure 3: Surface area of mandibular condylar layers. (a) Fibrous, (b) proliferative, (c) hypertrophic, and (d) cartilaginous layers in rats treated by LED, laser with or without functional appliance (FA). It can be seen that LED increases surface areas in (a), (b), and (d) compared to control and almost similar to control in (c).
