Abstract

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

Abstract

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.
