In-vitro Comparison of Dissolution Efficacy of Refined Orange oil over Xylene on Various Forms of Gutta Percha.

Abstract

For successful endodontic re-treatment, complete removal of fillingfrom the root canals is essential.Towards this end, solvents are indispensible.Thisstudy was carried out to compare and evaluate the dissolving capability of refined orange oil over xylene on various forms of gutta percha.30, ISO No. 40, 2% taper cones of Gutta Percha, Chlorhexidine Active points and Calcium hydroxide plus pointseach, were selected and placed in Group A, B and C respectively. Each group was further subdivided into two subgroups, which were treated with Xylene and Orange Oil solvent respectively, for 5 minutes, at room temperature. Each sample was weighed before and after immersion on a digital analytical scale.Data obtained was subjected to paired't' test,one way ANOVA test and scheffe's test. Results shows that the weight loss of all types of gutta percha was more in Xylene thanOrange oil but the difference was not statistically significant.Orange oil can be used as an effective guttta percha solvent.
