Abstract
The properties of dental cyanoacrylate cement "FH", which has protective and bacteriostatic effect on dental pulp, were compared with that of glass-ionomer cement. The operational properties such as setting time and consistency were good, but the mechanical properties as dental cement were a little inferior. These properties were affected definitely by temperature and humidity than the glass-ionomer cement, especially the influence of humidity was very high. However, the influence on bond strength was almost nothing, especially in the early period of setting. The factors affecting it could be very low disintegration. The bond strength for dentin after 24 hours the start of mixing of FH cement was much higher than that for enamel, but the strength rapidly decreased by thermal cycling between 4℃ and 50℃ in water.
