Effect of chloroform, eucalyptol and orange oil solvents on the microhardness of human root dentin

T
his study aimed to assess the effect of chloroform, eucalyptol and orange oil solvents on the microhardness of human root
dentin. Sixty-eight single-rooted single-canal extracted human premolar teeth were used. Tooth crowns were separated from
the roots at the ce- mentoenamel junction (CEJ). Roots were buccolingually sectioned into mesial and distal halves. Specimens were
randomly divided into 5 groups, with 20 teeth in each solvent group and 4 teeth in each control group. Primary microhardness of
specimens was measured using Vickers microhardness tester. Specimens were ex-posed to solvents for 15 minutes and were subjected
to microhardness testing again. Data were recorded and analyzed using repeated measure ANOVA. No significant difference was
found in dentin microhardness before and after exposure to solvents in any of the orange oil, eucalyptol, chloroform or saline groups
(P=0.727). None of the experimental groups showed any significant difference in terms of dentin microhardness reduction (P=0.99)
and had no significant difference with the negative control group. This study showed that chloroform, eucalyptol and orange oil as
gutta percha solvents did not decrease the microhardness of root dentin. Thus, none of the mentioned solvents has any superiority
over the others in terms of affecting dentin properties.
