Microleakage of Ormocer-based Restorative Material in Primary Teeth: An In Vivo Study
Saad D. Al-Harbi / Najat Farsi

This in vivo study aimed to compare, by means of dye penetration, the microleakage values of an Ormocerbased material (Admira) and a commonly-used composite resin (Restorative Z-100) and to assess the differences in the degree of microleakage according to the cavity wall location for both tested materials. No statistically significant differences were found in the degree of microleakage between the 2 materials or the location of cavity walls. Additional preventive measures should be considered to minimize leakage since none of the restorative systems used, eliminated microleakage.
