Background and Aim: The aim of this study was to compare
the coronal microleakage of various temporary fillings (TFs) in
endodontic access cavities in extracted human teeth using a
methylene blue dye penetration test.
Materials and Methods: Standardized access cavities were
prepared in 100 extracted human premolars. The teeth were
then randomly divided into 9 groups of 10 teeth, with the
remaining teeth serving as positive and negative controls. The
cavities in the experimental groups were filled with 4 mm of
Cavit G, Coltosol F, BMS, Fermin, Ketac Molar Easymix, Clip, ProFill, DuoTEMP, or TempBond Clear with Triclosan TFs according
to the manufacturer’s instructions. After thermocycling for
500 cycles (5-55°C), microleakage was measured by using a
methylene blue dye penetration test. The teeth were sectioned,
and the greatest depth of dye penetration was recorded.
Coronal microleakage was evaluated with a stereomicroscope.
Data was analyzed with Kruskal-Wallis and Mann-Whitney U
tests with Bonferroni correction (p≤ 0.05).
Results: Positive controls displayed complete dye penetration,
and negative controls showed no dye penetration. Whereas
Pro-Fill led to a statistically significantly lesser coronal sealing
ability than DuoTEMP, BMS, Coltosol, Cavit-G (p≤ 0.05), there
was no significant difference between the other groups
(p>0.05). However, Ketac Molar Easymix showed lowest
leakage (p≤ 0.05).
Conclusion: All TFs displayed some degree of leakage. The
results of this study indicate that Ketac Molar Easymix is not
suitable material for temporary filling. Other materials can be
used, but should be considered their variable leakage rates
