New Therapeutics in Promoting and Modulating Mandibular Growth in Cases with Mandibular Hypoplasia

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).

(a) Fibrous layer surface area in µm²

(b) Proliferative layer surface area in µm²

(c) Hyoertrophic layer surface area in µm²

(d) Chondrocyte layer surface area in µm²
