Prevention of Bacterial Infiltration in Class 1 Temporary Restorations Using Zinc Oxide/Calcium Sulphate Filling Materials: An In Vitro Study

This study evaluated sealing properties of zinc oxide/calcium sulphate filling material (Plastor©) to prevent bacterial infiltration in simulated Class 1 cavities with and without the presence of a spacer apically the restoration.

description This study evaluated sealing properties of zinc oxide/calcium sulphate filling material (Plastor©) to prevent bacterial infiltration in simulated Class 1 cavities with and without the presence of a spacer apically the restoration. Twenty-eight experimental Eppendorf tubes containing Tryptic Soy Agar were prepared and divided into seven groups: group A (Plastor©), group B (Plastor© + cotton pellet), group C (Plastor© + cotton pellet soaked of m-cresyl acetate), group D (Plastor© + cotton pellet soaked of eugenol), group E (Plastor© + PTFE pellet), group F (positive control), and group G (negative control). All prepared vials were individually immersed in tubes containing 5 mL of a suspension of <i>Streptococcus mutans</i> (10<sup>5</sup> CFU/mL) previously prepared and then incubated at 37 °C for 5 and 10 days. Subsequently, agar was collected and tested for <i>S.mutans</i> using real-time PCR. Aliquots of each agar samples were separately seeded on TSA for <i>S. mutans</i> isolation. The real-time PCR tests were negative for <i>S. mutans</i> on all the vials at both T5 and T10, except for positive control resulted positive at both T5 and T10. The isolation tests showed bacterial growth of <i>S. mutans</i> only with the agar samples collected from the vials of positive control, confirming real-time PCR tests. This in vitro study evidenced complete sealing ability of zinc oxide/calcium sulphate in temporary restorations of Class 1 cavities without mechanical loading at 10 days and complete immersion in a bacterial suspension. Moreover, sealing ability is not influenced by presence of spacers.
