Release of Matrix Metalloproteinases by Macrophages in Radicular Cysts and Residual Radicular Cysts

Introduction:

Radicular cysts (RCs) and residual radicular cysts (RRCs) are the sequelae of dental caries and that leads to proliferation of epithelial rests of Malassez in periapical tissues.

Objectives:

The aim was to evaluate the relationship between Langerhans cells, macrophages, matrix metalloproteinases (MMP-9, MMP-13), and tumor necrosis factor-alpha (TNF-α) in the capsule and lining epithelium of cystic lesions.

Materials and Methods:

Twenty RCs and 20 RRCs were submitted to immunohistochemical analysis with anti-CD68, anti-CD1a, anti-MMP-9, anti-MMP-13, and anti-TNF-α antibodies. The Mann-Whitney test and the Spearman correlation test were used for analysis of the data (P
