|
The purpose of this study was to evaluate the sealing ability according to types of spreader and compatibility of accessory cone used in lateral condensation method. 120 plastic blocks with canal preformed were instrumented with K-, H-files and
Gates-Gllidden bur. Shaped plastic blocks were divided into six experimental groups according to spreader and accessory cone used in lateral condensation. Then they were obturated by lateral condensation method without sealer. Six experimental
groups
were as follows:
@ES The obtained results were as follows;
@EN 1. In groups using two spreaders(Group 5.6), the linear leakage was less than one spreader using groups(Group 1-4).
