Chemical and mechanical influence of root canal irrigation on biofilm removal from lateral morphological features of simulated root canals, dentine discs and dentinal tubules

Abstract

Chemical and mechanical influence of root canal irrigation on biofilm removal from lateral morphological features of simulated root canals, dentine discs and dentinal tubules.

The influence of time and irrigant refreshment on biofilm removal from lateral morphological features of simulated root canals

“…NaOCl removed significantly more biofilm from the lateral canal‐ and isthmus‐like structure than the inert active control. This is in contrast to an earlier study using the same model (Pereira et al 2020b). However, in that study, irrigant exposure time was 30 s and the flow was constant.…”

“…active control. This is in contrast to an earlier study using the same model (Pereira et al 2020b). However, in that study, irrigant exposure time was 30 s and the flow was constant.…”

“…Higher flow rate removed significantly more biofilm only from the isthmus‐like structure. Earlier studies using the same root canal model also demonstrated that flow rate had a higher impact on biofilm removal from an isthmus‐like structure than a lateral canal‐like structure ((Pereira et al 2020a,b) Macedo et al . 2014b).…”

“…It has also been demonstrated that lower concentration NaOCl solutions have a significantly less effective reaction rate compared to high concentration solutions, even after multiple refreshments of the former (Macedo et al 2014a). Moreover, a constant flow of a 2% NaOCl using syringe irrigation did not remove more biofilm from lateral morphological features than an inert control solution (Pereira et al 2020b). In addition, within 30 s of exposure, increasing NaOCl concentration did not significantly improve the removal of biofilm from lateral morphological features (Pereira et al 2020a).…”
