Description
Abstract
Aim: The aim of the present study was to evaluate the microleakage of metallic copings luted with three
different commercially available luting cements.
Methods: The study was conducted at Department of Dentistry. 24 replicas of abutment analog having length 5
mm, width of platform 4.8 mm, taper 6°, broad chamfer finish line and three anti‑rotation grooves over it which
end 1 mm above finish line were milled from titanium rods.
Results: The result showed microleakage scores for specimens cemented with zinc oxide non‑eugenol, zinc
polycarboxylate and zinc phosphate luting cements, respectively. All specimens exhibited microleakage to
different degrees. Mean microleakage score was least for Zinc Phosphate cement (1.078±0.32), followed by
Zinc Polycarboxylate cement (1.6±0.84) and most for zinc oxide non‑eugenol (2.3±0.87). On subjecting the
values of mean microleakage scores to Kruskal–Wallis ANOVA followed by Chi‑square test, the value of P =
0.001 indicating that there was significant difference in mean microleakage scores of the groups tested (P <
0.05).
Conclusion: Within the limitations of the study, it was found that all cements exhibited certain amount of
microleakage. Zinc Phosphate cement exhibited a mean microleakage score that was significantly lower than
Zinc Oxide Non Eugenol cement and Zinc Polycarboxylate cement. When microleakage scores of Zinc Oxide
Non Eugenol cement and Zinc Polycarboxylate cement were compared, the difference was found to be
insignificant indicating that microleakage in these cements was similar.
