Fibronectin and fibronectin FN-ED-A expression in phenytoin-induced gingival overgrowth and no overgrowth control tissues. A: Representative immunohistochemistry-stained sections from suboral connective tissue (ct) of phenytoin-induced gingival overgrowth (PHE) and control (CON) tissues. Scale bar = 35 μm at ×400 magnification. B: Histomorphometric and quantitative analyses of fibronectin immunostaining in phenytoin-induced gingival overgrowth (PHE) in subsulcular and suboral connective tissues compared with no overgrowth control (CON) tissues. C: Histomorphometric and quantitative analyses of FN-ED-A immunostaining in phenytoin (PHE)-induced gingival overgrowth in subsulcular and suboral connective tissues compared with control (CON) tissues. For fibronectin analyses: n = 9 in no overgrowth control; n = 5 for phenytoin overgrowth. For FN-ED-A analyses: n = 6 for no overgrowth control; n = 5, phenytoin. Data are means ± SE; *P < 0.05 compared with control by analysis of variance with Bonferroni correction for multiple tests.
