There seems to be no convincing evidence to support the superiority of any material over ZOE , and both ZOE and IP + Ca appear to be suitable as root canal fillings for deciduous teeth
The aim of this systematic review was to determine whether there is a root canal filling for deciduous teeth equally or more effective than zinc oxide-eugenol cement ( ZOE ) .
Evaluation of a mixture of zinc oxide, calcium hydroxide, and sodium fluoride as a new root canal filling material for primary teeth.
Endodontic treatment was performed on 25 pulpally involved m and ibular primary molars in 4 to 9-year-old children ; the root canals were obturated with a new root canal filling material consisting of a mixture of calcium hydroxide , zinc oxide , and 10 % sodium fluoride solution , using h and -operated lentulo-spirals . All cases were evaluated clinical ly every 3 months and also radiographically every 6 months to assess the success of the treatment ; we also examined the resorption of the root canal filling material from the root canals and the status of overpushed material , if any , as the tooth resorbed with the passage of time . At 6 months , endodontic treatment in 2 of the 25 teeth had failed and one tooth had exfoliated ; the remaining 22 teeth were without any signs or symptoms . At the end of 2 years , 14 teeth could be evaluated ; out of these 12 had physiologically exfoliated . It was observed that the rate of resorption of this new root canal obturating mixture was quite similar to the rate of physiologic root resorption in primary teeth . In three cases , where there was an overpush of the mixture , a gradual partial resorption was noted
