0.05). However, the mixture of calcium hydroxide/distilled water did not completely eradicate E. faecalis from dentinal tubules at any period of time.Conclusion: According to the results of this study, calcium hydroxide mixed with CHX or NaOCl is better than calcium hydroxide mixed with distilled water for dentin disinfection in cases of persistent intracanal infection.Key words: Enterococcus faecalis, Calcium hydroxide, Candida albicans, Chlorhexidine, Root canal medicaments, Sodium hypochlorite]]>

0.05). There was not a statistically significant difference, between the mean shear bond strength of GC Fuji LC2, using polyacrylic acid 20% and the same material using phosphoric acid 35%. However, there was a significant difference between the strength of shear bond of the two above materials and composite 3MZ100 ( p <0.001).Conclusions: According to the results of this study, it can be concluded that 1- Application of APF, has little effect on reducing the strength of shear bond in GC Fuji LC2 and 3MZ100 composite. Moreover, 2- Using polyacrylic acid 20% and phosphoric acid 35% have similar effects on the strength of glass ionomer GC Fuji LC2 to the primary tooth enamel.Key words: Fluoride, Topical, Shear strength, Glass Ionomer, Enamel, Primary teeth]]>

However, GI and ZPH cements made by Ariadent were acceptable according to ISO 9917 standards.Key words: Compressive strength, Dental cement, Glass ionomer, Zinc phosphate.]]>

0.05), but Pro Root MTA and Root MTA had significant differences with Portland cement ( p <0.05). Pro-root MTA had the lowest apical microleakage followed by root MTA and Portland cement respectively.Conclusion: Considering the results of this study, Portland cement cannot be replaced with Pro-root MTA in retrograde fillings, but using Root MTA as a substitute for Pro Root MTA needs more investigations.Key words: Microleakage, Pro Root MTA, Portland cement, Root MTA, Root canal filling material]]>
