    Effectiveness of xylol, orange oil and eucalyptus oil in dissolving gutta-percha: in vitro study
    (Universidad Privada Norbert Wiener, 2019-02-25) Menacho Valdivieso, Johnny Ronal; Ordoñez Lopez, Carmen Jenny
    The objective of this research was to determine the effectiveness of xylene, orange oil, and eucalyptus oil in dissolving gutta-percha. For this purpose, three solvent substances commonly used in dentistry (xylene, orange oil, and eucalyptus oil) and 60 gutta-percha discs, 8 millimeters in diameter and 2 millimeters in width, were used. The sample size was calculated using a sample calculation method, with 20 gutta-percha discs for each substance used. The initial weight of the discs was recorded, and then they were placed in Petri dishes containing the studied substances. The discs were submerged in these substances and were removed at 2 minutes and 5 minutes for immersion in distilled water to stop the solvent effect. The discs were weighed again, and the weight was recorded in the data collection sheet. The results showed that xylene dissolved 0.53 grams of gutta-percha after 2 minutes of exposure. Orange oil dissolved 0.44 grams, and eucalyptus oil dissolved 0.39 grams. After 5 minutes, xylene dissolved 1.15 grams of gutta-percha, while orange oil dissolved 0.94 grams, and eucalyptus oil dissolved 0.89 grams of gutta-percha. It was concluded that there was no statistically significant difference between the various gutta-percha solvents at 2 and 5 minutes of exposure.
