Discoloration of Roots Caused by Residual Endodontic Intracanal Medicaments
Figure 1
Effect of paste type, paste removal method, and time on normalized luminosity of roots. Graphs show change in a percentage of discolouration over time. (a) shows data for paste exposure of 2 weeks and (b) for 4 weeks. Each data series shows the mean of 10 roots and each data point on the timeline represents the mean of 20 images at that storage time (2 per root to show both sides). Error bars have been omitted for clarity.
