Abstract
This study measured the in vitro microleakage of conventional and new FPD luting agents.
Standardized preparations were made on 42 freshly extracted premolars. Facial and
lingual chamfer margins were placed in enamel, mesial and distal in dentin and cementum,
and castings were made in Rexillium III alloy and were then cemented with a standardized
technique. Six groups of seven samples were tested, (1) polycarboxylate, (2) zinc
phosphate, (3) glass ionomer, (4) Den-Mat Thin Film cement, (5) Panavia Ex, and (6)
Den-Mat Thin Film cement with Tenure. The ranking of groups for stain ingress was
from the greatest (1) to the least (6). A one-way analysis of variance and Tukey-Student
range analysis revealed significantly similar groups, p < 0.05:(1,2,3,4) (5,6).
