Aim:
The purpose of this in vivo study was to evaluate and compare the efficacy of different obturating methods used in primary teeth, when obturated using a combination of zinc oxide and iodoform paste (Endoflas F.S.).
Materials And Methods:
A group of 29 patients aged 3-9 years and a total of 64 teeth were selected. These 64 teeth (32 anterior teeth=32 canals, and 32 posterior teeth=80 canals) were randomly divided into 4 groups. Teeth were obturated with Lentulo spiral, pressure syringe, bi-directional spiral and Pastinject. Post-operative evaluation was done for: quality of canal obturation, (underfilled, optimally filled, overfilled) and presence of voids.
Results:
Pastinject exhibited the highest number of optimally filled canals, while the highest number of underfilled canals were observed with bi-directional spiral, and the highest number of overfilled canals were observed with pressure syringe. A minimum number of voids was present in canals filled with the Pastinject technique and pressure syringe.
Conclusion:
These results suggest that Pastinject was the most effective technique for obturation of primary teeth.
