When CHX is associated with sodium hypochlorite, a brown orange (parachloramine) is formed at the canal surface and it affects the canal obturation
with the resin cements.
Several endodontic epidemiological studies had been carried out in different population groups to assess technical quality of root filling in relation to performer experience performed by undergraduate students using standard step back canal preparation technique followed by lateral condensation for canal obturation.
Comparative Radiographic Assessment of Root Canal Obturation Quality: Manual Verses Rotary Canal Preparation Technique.
An in vitro evaluation of the apical sealing ability of a new resin-based root canal obturation
There has been debate as to the optimal length of canal preparations and the optimal level of canal obturation
Root surface temperature rises in vitro during root canal obturation
using hybrid and microseal techniques.
Impact of smear layer on sealing property of root canal obturation
using 3 different techniques and sealers.
The aim of this study was to assess the effect of three different root canal irrigation solutions on the apical sealing ability of three different root canal obturation materials: gutta-percha with AH plus or MM-seal and Resilon with Epiphany SE.
Each irrigation group was further divided into three groups according to the use of three different root canal obturation materials (n = 10): Gutta-percha with AH plus (Dentsply, Konstanz, Germany) or MMseal (Micro-Mega, Besangon, France), Resilon with Epiphany SE (Pentron Clinical Technologies, Wall ingford, CT, USA).
Root canal obturations
were done with lateral condensation using AH 26 root canal sealer (DentsplyMaillefer, Tulsa, Ok, US) and gutta percha.
