Abstract

Objective: The aim of this study was the comparative evaluation of the effectiveness of orange oil, turpentine oil, and chloroform in dissolving gutta-percha and GuttaFlow discs.

Materials and Method: Forty-five discs (10 mm in diameter and 2 mm in thickness) made from GuttaFlow and gutta-percha were prepared. After weighing the initial mass by using an analytical balance, specimens were randomly divided into 3 groups (n=15) according to solvent type. GuttaFlow and gutta-percha specimens were immersed in solvents for 10 min and then reweighed. The difference between the final and initial weights of specimens was considered the mass dissolved by solvents. Two-way ANOVA test with Bonferronni correction and Tukey test were used for the statistical analyses.

Results: Chloroform dissolved significantly more gutta-percha (p=0.000) and GuttaFlow (p=0.000) than orange oil or turpentine. There was no statistically significant difference between the effectiveness of orange oil and turpentine oil in dissolving both gutta-percha (p=0.985) and GuttaFlow (p=0.713). Conventional gutta-percha discs dissolved in the solvents more than GuttaFlow discs did (p=0.000).

Conclusion: Chloroform was more effective in dissolving conventional gutta-percha and GuttaFlow discs compared to orange oil and turpentine. Conventional gutta-percha dissolved more than GuttaFlow did in the tested solvents. Removal of GuttaFlow via chemical solvents could be more difficult than for conventional gutta-percha in retreatment cases.

Üç farklı çözücünün geleneksel güta-perka ve GuttaFlow üzerine etkisinin değerlendirilmesi: in vitro

Abstract

Amaç: Portakal yağı, turpentin ve kloroformun güta-perka ve GuttaFlow diskleri üzerindeki çözücü etkilerinin karşılaştırmalı incelenmesidir.

Gereç ve Yöntem: GuttaFlow ve güta-perka konlar kullanılarak kırkbeşer disk (10 mm çapında ve 2 mm kalınlığında) hazırlandı. Örnekler deney öncesinde elektronik hassas terazide tartılarak kullanılacak çözücü tipine göre rastgele 3 gruba ayrıldı (n=15). GuttaFlow ve güta-perka örnekleri çözücü içerisinde 10 dk bekletilerek tekrar tartıldı. Disklerin ilk ağırlık ve son ağırlık farkları, çözücüler tarafından uzaklaştırılan miktar olarak kaydedildi. İstatistiksel analizler Bonferroni düzeltmeli two-way ANOVA ve Tukey testleri kullanılarak yapıldı.

Bulgular: Kloroform, portakal yağı ve turpentinden anlamlı şekilde daha fazla güta-perka (p=0.000) ve GuttaFlow (p=0.000) kitlesi çözdü. Portakal yağı ve turpentin arasında hem güta-perka (p=0.985) hem de GuttaFlow (p=0.713) çözücü etkinliği açısından anlamlı fark olmadığı bulundu. Geleneksel güta-perka disklerinin GuttaFlow disklerine göre çözücülerde anlamlı olarak daha fazla çözündüğü saptandı (p=0.000).

Sonuç: Kloroformun hem geleneksel güta-perka hem de GuttaFlow kanal dolgu materyali üzerinde portakal yağı ve turpentine oranla daha etkili olduğu bulundu. Araştırılan çözücülerde geleneksel güta-perka, GuttaFlow kanal dolgu maddesine göre daha fazla çözülebilmektedir. Kanal tedavisi yenileme vakalarında, GuttaFlow’un kimyasal çözücülerle uzaklaştırılması geleneksel güta-perkaya göre daha güç olabilir.
