EFFECT OF DENTIN SURFACE TREATMENT ON LEAKAGE OF PULP SPACE OBTURATIONS IN CANALS TREATED WITH ETHYLENE DI-AMINE TETRA ACETIC ACID AND SODIUM HYPOCHLORITE: AN IN VITRO STUDY

Abstract

In the present study,spectrophotometric analysis was carried out to quantitatively analyse the amount of dye leakage with four sealers. Twenty four distal roots of mandibular molars were selected and randomly divided into four groups with six specimens. After cleaning and shaping, obturation was done with gutta- percha.The sealers used in the four groups were Zinc oxide eugenol, Ketac endo,Light cured glass ionomer, Dyract AP thinned out with prime and bond 2.1. It indicated maximum transmission   with zinc oxide eugenol and least with ketac endo, indicating least leakage with zinc oxide eugenol and maximum with ketac endo.
