Figure 5
Changes in the collagen fibres of PDL specimens after collagenase
treatment, as represented by the area occupied by birefringent fibres in
each grid (Figure 4).
Data were analysed for specimens treated with PBS (a), 8 units/mL
collagenase (b), 16 units/mL collagenase (c), or 24 units/mL collagenase
(d). Each column represents the mean of six specimens.
