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

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.

Evaluation of the effectiveness of three different solvents in dissolving gutta-percha and Gutta Flow: in vitro

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 guttapercha 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 guttapercha (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 guttapercha 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.
