[Effect of Carisolv on root canal cleanness in chemomechanical preparation].
OBJECTIVE
To evaluate the effect of Carisolv as chemical reagent on root canal cleanness in chemomechanical preparation.


METHODS
Sixty extracted teeth which were dyed with methylene blue were randomly divided into 3 groups, different chemical reagents were applied in different groups. The optical density of methylene blue in irrigating solution were measured with UV-VIS spectrophotomer after preparation with each file, the root canal cleanness was evaluated under SEM. Two-way ANOVA and Kruskal-Wallis H test in SPSS 11.5 software package were used for statistical analysis.


RESULTS
There were significant differences in the optical density between the root canals treated with Carisolv and those with 2% tosylchloramide sodium plus 3% hydrogen peroxide (P<0.05), no significant difference was found in optical density between the root canals treated with Carisolv and those with 2.5% sodium hypochlorite (P>0.05). The results of SEM were consistent with those of the optical density of methylene blue.


CONCLUSIONS
As a chemical reagent, the cleaning ability of Carisolv was as effective as 2.5% sodium hypochlorite. Carisolv can remove the smear layer and debris, without causing excessive demineralization.
