Objective: To examine the cleaning efficiency of a novel non-aqueous solution on zinc-oxide eugenol-based temporary cements.

Methods: Twenty single-rooted anterior teeth were decoronated and split into two halves longitudinally with a diamond disc. The resulting forty tooth specimens were divided into 4 groups: uncleaned, mechanically cleaned, chemically cleaned, and untreated. Uncleaned specimens were treated with TempBond temporary cement with no cleaning regimen. Mechanically cleaned specimens were treated with TempBond, followed by 1 minute mechanical removal of the cured cement with a dental explorer. Chemically cleaned specimens were treated with TempBond, followed by 30 second application of a novel non-aqueous solution over the cured cement. Untreated specimens were left intact; no temporary cement was applied. Chloroform was used to extract eugenol from the tooth specimens, and the ensuing solutions were analyzed via gas chromatography-mass spectrometry. The cleaning efficiency was measured by the concentration of eugenol observed via GC-MS. Data were analyzed using 1-way ANOVA and the SNK multiple comparisons test at a significance level of p<0.05.

Results:

Conclusions: Tooth specimens chemically cleaned with a novel non-aqueous solution were found to contain a significantly smaller concentration of eugenol compared to uncleaned specimens and mechanically cleaned specimens. There was no statistically significant difference in the concentration of eugenol between uncleaned specimens and mechanically cleaned specimens.
