Abstract:
Objective To compare the efficacy of alkaline enzyme-containing versus multi-enzyme cleaner for pre-cleaning dental zinc phosphate cement fillers.Methods One hundred new dental cement fillers were selected and contaminated to moderate-to-heavy levels by simulating clinical contamination,and divided into the alkaline enzyme-containing group and the multi-enzyme group,with 50 cases in each group.The two groups underwent manual brushing followed by automated spray-type washer-disinfector cleaning.The effica-cy of the two groups of pre-cleaning were evaluated by naked-eye visual detection,10×illuminated magnifica-tion and residual protein quantification.Results The alkaline enzyme-containing group demonstrated signifi-cantly higher pass rates than the multi-enzyme group by naked-eye visual detection and 10×illuminated mag-nification(P<0.05),while there was no statistically significant difference in the residual protein quantifica-tion between the two groups(P>0.05).The qualified cleaning rates of the three parts of the instruments in the alkaline enzyme-containing group were all higher than those in the multi-enzyme group,but only the quali-fied cleaning rate of the handle threaded surface was statistically significant(P<0.05).There was no statisti-cally significant difference in the cleaning qualification rates of the instruments three parts of the alkaline en-zyme-containing group(P>0.05),while there was statistically significant difference in the cleaning qualifica-tion rates of the instruments three parts of the multi-enzyme group(P<0.05).Conclusion Compared with the multi-enzyme cleaner,alkaline enzyme-containing cleaner has better effects in the pre-cleaning of zinc phosphate cement fillers.
