Abstract

Aim: Evaluation in the effect of walking bleach agent on the coronal microleakage of Coltosol F, Biodentine, Cavit-G, MD-Temp and Zinc phosphate temporary restorative materials by stereomicroscopic analysis. An invitro study.  Materials and Method: Seventy-five extracted human maxillary central incisor teeth were collected and endodontic access cavity preparations were done on all specimens. All the teeth were prepared chemomechanically and obturated with gutta-percha in lateral condensation technique. All the teeth were then randomly divided into five groups. 15 teeth in each group, 10 teeth served as experimental specimens, in which bleaching agent was placed in the pulp chamber and 5 teeth served as control, in which no bleaching agent was placed. Access cavities were restored with temporary restorative materials being tested per each group respectively. All specimens were then immersed in 1% Indian ink dye for 72 hours. All the specimens were then longitudinally sectioned and observed with stereomicroscope and were graded according to the depth of linear dye penetration.  Results: Statistical analysis was done using Mann-Whitney U test and Kruskal-Wallis test. Cavit G, Coltosol F have shown minimal or no dye leakage compared to other temporary restorative materials used.  Conclusion: Cavit G and Coltosol F showed minimal or no dye leakage and were not influenced by the effects of walking bleach agent.
