An Comparative Evaluation of Antimicrobial Efficacy of Propolis, Morinda Citrifolia Juice, Sodium Hypochlorite and Chlorhexidine on and .

Aim: To evaluate the antimicrobial effectiveness of Propolis, Morinda citrifolia juice, Sodium hypochlorite and Chlorhexidine on () and ( ), as endodontic irrigants.

Materials And Methods: Four clinical isolates and one standard ATCC sample (29212) of and ATCC sample (90028) of C. albicans were inoculated into 5ml of peptone water each and incubated at 37° C for 3 to 4 hours to attain the turbidity corresponding to 0.

Comparison of Fracture Resistance of Heat Cure Resins Polymerized by Conventional and Microwave Methods after Immersion in Artificial Saliva.

Aim: To assess and compare the impact and flexural strength of heat cure acrylic resin polymerized by microwave and conventional methods after immersion in artificial saliva for 2 days, 60 days, 90 days and 120 days.

Materials And Methods: The present study was carried out on 160 specimens. They were categorized into two groups.

Time-Dependent Effect of Various Irrigants for Root Canal on Smear Layer Removal.

Background: Existence of smear layer in root canals caused by instrumentation is believed to prevent penetration of irrigating agents, thereby resulting in endodontic treatment.

Aims And Objectives: To compare and evaluate the effectiveness of two irrigants: 17% ethylenediaminetetraacetic acid (EDTA) and mixture of tetracycline isomer, an acid, and a detergent (MTAD) as final agents for eliminating the smear layer.

Materials And Methods: We included 50 human lower premolar teeth whose crowns were sectioned at cementoenamel junction.
