2013, Dental MaterialsCitation Excerpt :On one hand, it is a loosely adherent layer that can provide a pathway for microbial micro-leakage [19], it potentially harbors bacteria and can serve as a reservoir of irritants [20], it can provide a substrate for any remaining bacteria following chemo-mechanical disinfection of the pulp space [21], and can prevent the penetration of irrigation solutions and inter-appointment medication into the dentinal tubules, thus jeopardizing the effective disinfection during root canal treatment [22]. On the other hand, the smear layer can block the dentinal tubules and alter their permeability which can limit bacterial and toxin penetration [23]. Furthermore, bacteria surviving the disinfection protocol can be entombed within the dentinal tubules by the smear layer and the obturation material [24].
