Solubilizing efficiency of different gutta-percha solvents: A comparative study.

Abstract

Abstract:A study was conducted to comparatively evaluate the efficiency of different solvents for dissolving gutta-percha. Halothane, chloroform, xylene, acetone, isopropyl alcohol, turpentine, oil of mela-leuca and eucalyptol were used as solvents for dissolving standardized gutta-percha discs.Halothane, chloroform and xylene were markedly superior solvents of gutta-percha in comparison with the others. There was no significant difference among the three (p > 0.05). Eucalyptol, turpentine and oil of melaleuca were relatively less efficient.Acetone and isopropyl alcohol did not dissolve gutta-percha, being similar in this respect to distilled water.

In vitro study of effect of solvent on root canal retreatment

“…In the present study, xylol proved to be the most efficient. A comparative study of the dissolving efficiency of different solvents reported that xylol presents results similar to those of chloroform and halothane (15). Our results, however, showed that these two solvents were the least effective, perhaps due to their volatility.…”

Dissolving efficacy of eucalyptus and orange oil, xylol and chloroform solvents on different root canal sealers

“…For example, chloroform and xylol have been shown to dissolve most root filling materials (Tamse et al. 1986, Wennberg & Orstavik 1989, Görduysus et al. 1997, Whitworth & Boursin 2000, Schäfer & Zandbiglari 2002, Magalhães et al.…”

Essential oils are able to dissolve most endodontic sealers and some, such as orange oil, eucalyptus oil and pine oil, have been reported to be safe and useful for this purpose (Hunter et al 1991, Uemura et al 1997, Hansen 1998).…”

Evaluación in vitro de tres solventes de gutapercha

“…Por el contrario, el xileno está disponible actualmente para uso clínico, y no es considerado carcinogénico, aunque resulta ser muy tóxico para los tejidos. 3,13,18 La gutapercha también es soluble en aceites esenciales. Algunos de ellos han sido reportados como seguros y útiles para este propósito, por ejemplo, los aceites esenciales: eucalytus (eucalytol) y árbol de pino (turpentine) 14 .…”
