Introduction: The relationship between margins Vs plaque retention was very well documented furthermore, risk of secondary complications was elaborated in literature and suggested for routine follow-up & oral prophylaxis. Some investigators evaluated the effects of ultrasonic procedures on restorative materials, but the discrepancy of luting agent at the tooth and restoration interface of indirect restorations has not yet documented. Else this study was performed to evaluate the influence of peizoelectric ultrasonic procedures on marginal integrity of indirect restorations bonded with different luting agents.

Methodology: Extracted human premolars were prepared and prepared castings were luted with different luting agents. Specimens were subjected to piezoelectric ultrasonic procedures with different frequencies and evaluated the margin interface with a surface profilometer and scanning electron microscope.

Result: The specimens luted with glass ionomer cement has shown a lesser marginal discrepancy in both low and high frequencies than the samples luted with self-adhesive resin in low and high frequencies at the margins interface.

Conclusion: The specimens which have subjected to low frequency shown less discrepancy than the specimens subjected to high frequency irrespective of the luting agent. Samples luted with glass ionomer cement measured discrepancy of 2μm between low and high frequencies, whereas self-adhesive resin measured discrepancy of 7μm.
