XP-Endo Finisher’in kök kanal düzensizliklerinden kalsiyum hidroksit uzaklaştırma yeteneği üzerine sıcaklığın etkisi: ex vivo
Amaç: Bu çalışmanın amacı, XP-Endo Finisher’ın kök kanal düzensizliklerinden kalsiyum hidroksit (KH) uzaklaştırma kapasitesine sıcaklığın (çevre ve irrigasyon solüsyonunun) etkisini değerlendirmektir. Gereç ve Yöntem: Seksen üç dişin kök kanalı genişletildi ve dişler uzunlamasına ikiye ayrıldı. İki standart yarık (apikal ve koronalde) hazırlandı ve kökler rastgele beş deney grubuna (n=15), bir pozitif (n=4) ve bir negatif kontrol grubuna (n=4) ayrıldı. Yarıklar KH ile dolduruldu, kök yarımları tekrar birleştirildi, tüm kanal KH ile dolduruldu ve dişler 14 gün boyunca saklandı. Daha sonra KH aşağıdaki irrigasyon protokollerine göre uzaklaştırıldı. Ortam sıcaklığı ilk dört grup için 37 °C, Grup 5 için 21 °C idi. Grup 1: geleneksel iğne irrigasyonu ile 21 °C'deki NaOCl, Grup 2: geleneksel iğne irrigasyonu ile 37 °C'deki NaOCl, Grup 3: XP-Endo Finisher ile 21 °C'deki NaOCl, Grup 4: XP-Endo Finisher ile 37 °C'deki NaOCl, Grup 5: XP-Endo Finisher ile 21 °C'deki NaOCl kullanımıydı. İrrigasyon işleminden sonra artakalan KH miktarı bir stereomikroskop ile incelenerek skorlandı. İstatistiksel değerlendirme, Kruskal-Wallis analizi ve Mann-Whitney U testi Bonferroni düzeltmesi kullanılarak yapıldı. Bulgular: Grup 3 ve 4, apikal bölgede diğer gruplara göre anlamlı derecede daha fazla KH uzaklaştırdı (p<0.05). Koronal bölgede gruplar arasında fark yoktu (p>0.05). KH uzaklaştırılması, irrigasyon solüsyonunun sıcaklığından etkilenmedi (p>0.05) ancak çevre sıcaklığından (Grup 3’e karşı Grup 5; p<0.05) ve KH uzaklaştırma tekniğinden (Grup 3 ve 4’e karşı Grup 1 ve 2; p<0.05) önemli derecede etkilendi. Sonuç NaOCl solüsyonunun sıcaklığı XP-Endo Finisher’ın KH kaldırma etkinliğinde önemli bir rol oynamazken, çevre sıcaklığı etkinliğini arttırdı.

Effect of temperature on the ability of XP-Endo Finisher to remove calcium hydroxide from root canal irregularities: ex vivo
Objective: The purpose of this study was to evaluate the effect of different environmental temperatures and irrigation solution temperatures on the calcium hydroxide (CH) removal efficacy of XP-Endo Finisher from root canal irregularities. Materials and Method: Eighty-three teeth were instrumented and split longitudinally. Two standard grooves (apical and coronal) were prepared, and the roots were randomly divided into five experimental groups (n=15), a positive control group (n=4), and a negative control group (n=4). The grooves were filled with CH, the root halves were re-assembled; the canal space was also filled with CH, and the teeth were stored for 14 days. Fourteen days later, CH was removed using one of the following irrigation protocols, where environmental temperature for Groups 1-4 and Group 5 were 37 °C and 21 °C, respectively: Group 1: Conventional needle irrigation with NaOCl at 21 °C; Group 2: Conventional needle irrigation with NaOCl at 37 °C; Group 3: XP-Endo Finisher with NaOCl at 21 °C; Group 4: XP-Endo Finisher with NaOCl at 37 °C; Group 5: XP-Endo Finisher with NaOCl at 21 °C. The amount of the remaining CH after the removal was examined and scored by using a stereomicroscope. The statistical evaluation was performed using Kruskal–Wallis and Mann–Whitney U tests with Bonferroni-correction. Results: Group 3 and 4 removed significantly more CH than the other groups in the apical region (p<0.05). There were no significant differences between the groups in the coronal region (p>0.05). The removal of CH was not affected by the temperature of the irrigation solution (p>0.05); but it was significantly affected by the environmental temperature (Group 3 versus Group 5; p<0.05) and the CH removal technique (Groups 3 and 4 versus Groups 1 and 2; p<0.05). Conclusion: While the temperature of the NaOCl solution did not play a significant role in the CH removal efficacy of XP-Endo Finisher, greater environmental temperature increased its activity.
