Abstract

Abstract:

Simulated functional maxillary inclined planes were used for experimental rats to guide mandibles forwards. The immunohistochemical ABC method was performed to analyze the distribution of estrodial in the mandibular condylar cartilages. The results showed that estrodial was distributed mainly in the germinal layers of the cartilages with more distribution during their actively proliferative period. Estrodial was located mainly in the nuclei of the chondrocytes. More distribution of estrodial was viewed after functional mandibular protrusion, accompanied with much E 2 positive staining. It is suggested that estrodials play an important role in promoting the growth and functional adaptive remodeling in the condylar cartilages.

Key words: condylar cartilages, estrogen, immunohistochemical
