Table 1. Comparison of gelatinolytic activity of MMPs in irradiated and / or demineralized primary teeth, performed by means of in situ zymography. The integrated density of fluorescent signal/mm 2 (median and interquartile range) in the cervical region, at the cusp and at the groove was measured at the same depth and in the same area.
