Non-instrumentation Root Canal Treatment of Primary Molars

After local anesthesia and rubber dam isolation, the pulp chamber will be accessed. After the location of root canals entrance, an initial irrigation will be conducted using 1% sodium hypochlorite. Then, a paste containing two antibiotics (chloramphenicol and tetracycline) and zinc oxide and eugenol (CTZ paste) will be placed in the pulp chamber floor, into the root canal entrances. Then, a layer of glass ionomer cement will be placed, and the teeth will be restored with bulk-fil resin composite.

After anesthesia and rubber dam isolation, pulp chamber will be accessed with burs, and the root canals entrance will be prepared using a Gates Glidden bur. The root canal length determination will be done subtracting 1 mm from the radiographic measurements performed on the different roots. The instrumentation will be performed with 21mm stainless steel endodontic hand K-files, with International Organization for Standardization (ISO) tip ranging from #08 to #35. Irrigation will be performed using 1% sodium hypochlorite. After the last file, a final irrigation will be conducted with ethylenediaminetetraacetic acid and tegentol (EDTA-T) and 0.9% sodium chloride solution, and the root canals will be dried with paper points. Then, the root canals will be filled with a Zinc Oxide and Eugenol paste (ZOE paste), inserted into the root canals with a lentulo spiral. A layer of glass ionomer cement will be placed, and the teeth will be restored with bulk-fil resin composite.
