ABSTRACT
Objective@# The short-term clinical effects of two kinds of normal temperature flow root sealers (the calcium silicate-based sealer iRoot SP and the siloxane-based sealer GuttaFlow2) combined with single point filling technology and a frequently-used sealing agent (AH Plus) combined with continuous wave hot tooth filling technology were evaluated. @*Methods @#A total of 279 teeth (656 root canals) were randomly divided into three groups: the iRoot SP group, GuttaFlow2 group and AH plus group. We recorded the filling time of each root canal, collected a digital dental film to evaluate the filling effect of each root canal, and conducted a follow-up visit one week and one month after the operation to record the incidence of pain. We used SPSS 18.0 to analyze the above data. @*Results @# There was no significant difference in the root canal filling effect among the three groups (P > 0.05). There was no significant difference in the filling time between the iRoot SP group and the GuttaFlow2 group (P > 0.05), but the filling time was significantly shorter in the AH Plus group (P < 0.05). There was no significant difference in the postoperative pain between the iRoot SP group and the GuttaFlow2 group (P > 0.05), and the incidence of pain in the iRoot SP group and the GuttaFlow2 group was lower than that in the AH Plus group (P < 0.05).@*Conclusions @# GuttaFlow2 and iRoot SP combined with single point filling technology can save filling time and obtain good clinical effects compared with frequently-used hot tooth filling technology and the incidence of postoperative pain was low.
