In vitro study of essential oils efficacy as alternative solvents in endodontic retreatment. (English)

Introduction: The aim of this study was to investigate the solubility of gutta-percha points and various endodontic sealants in essential oils. Materials and method: Ninety-six gutta-percha points were divided into the four groups of 24 samples for every essential oil and subsequently divided into the three subgroups corresponding to the immersion times (2,10 and 15 min). The post-immersion amount was obtained for each. Endodontic sealers AHplus, Acroseal, Endomethasone N were included in the research. Samples were treated with corresponding oil for 10 min. Each sample was measured and the amount was obtained. Results: Orange oil was the most effective in dissolving gutta-percha compared to other tested essential oils (p < 0.05). Eucalyptol was more effective in dissolving gutta-percha than tea tree after 10 min (p < 0.05). There was no statistical significance in the effectiveness of essential oils in relation to the time of action (10 or 15 minutes) (p > 0.05). Most weight loss was recorded with Endomethasone for all solvents, but the highest in orange oil and tea tree, followed by eucalyptus and clove oil. Tea tree dissolved AH Plus more efficiently compared to Acroseal. Conclusion: Essential oils showed promising results in dissolving gutta-percha and sealers. [ABSTRACT FROM AUTHOR]

Uvod: Cilj rada je bio da se ispita rastvorljivost gutaperka poena i različitih endodontskih silera u eteričnim uljima. Materijal: i metode rada U istraživanju je 96 gutaperka štapića podeljeno u četiri grupe od 24 uzorka za svako testirano eterično ulje i potom podeljeno u tri podgrupe za svako imerziono vreme (2, 10 i 15 min.). Za svaki uzorak je merena postimerziona težina. Paste za opturaciju AH Plus, Acroseal i Endometazon N su uključene u ispitivanje. Uzorci sa pastama su potapani u rastvarač na 10 min. Posle potapanja u testiranim eteričnim uljima, merene su težine svih uzoraka. Rezultati: Pomorandžino ulje je najefikasnije u rastvaranju gutaperke u odnosu na druga testirana eterična ulja (p < 0,05). Eukaliptol je više rastvorio gutaperku nego ulje čajevca posle 10 min. (p < 0,05). Nema statističke razlike u efikasnosti ulja u odnosu na to da li deluju 10 ili 15 min. (p > 0,05). Najveći gubitak mase je zabeležen kod paste Endometazon u svim rastvaračima, najviše u ulju pomorandže i čajevca, zatim ulju eukaliptusa i karanfilića. Čajevac rastvara AH Plus efikasnije nego Acroseal. Zaključak: Eterična ulja imaju potencijal za rastvaranje gutaperke i pasta za opturaciju kanala korena. [ABSTRACT FROM AUTHOR]
