Sustained-Release Fillers for Dentin Disinfection: An Ex Vivo Study

Figure 1

Dentin depth. The white circle represents the root canal prepared with an ISO size #011 bur. Colored circles represent different dentin layers at increasing depths, sampled by incrementing bur sizes (ISO #014, #018, #020). Red solid lines represent dentin depths covered by each bur, starting from the root canal wall (dashed blue line). Dentin depth = (Ø bur − Ø root canal)/2.
