KÖK KANALININ APİKALİNDE YAPAY OLARAK STANDARDİZE EDİLMİŞ OLUKTAN KALSİYUM HİDROKSİTİN UZAKLAŞTIRILMASINDA QMİX SOLÜSYONUNUN ETKİNLİĞİ
Bu çalışmanın amacı kök kanalının apikalinde
yapay olarak standardize edilmiş oluklardan kalsiyum hidroksitin (KH)
uzaklaştırılmasında QMix 2 in 1 solüsyonunun etkinliğini değerlendirmektir. 118
adet çekilmiş tek köklü üst kanin dişi ProTaper sisteminin F5 boyutundaki
eğesine kadar genişletildi. Bu dişler uzunlamasına olarak 2 'ye ayrıldı ve her
bir parçanın apikal kısmında standardize edilmiş oluk hazırlandı. Sonrasında bu
oluklar distile su ile kalsiyum hidroksit tozunun karıştırılmasıyla elde edilen
pat ile dolduruldu ve bu dişler yeniden birleştirildi. KH’i uzaklaştırmak için dişler aşağıdaki irrigasyon
protokolüne göre, rastgele 2 kontrol ve 6 deneysel grubuna ayrıldı. (1)
Konvansiyonel şırınga irrigasyonu (KŞİ)/Sodyum Hipoklorit (NaOCl)+Etilendiamin
Tetraasetik Asit (EDTA) , (2) QMix/KŞİ, (3) NaOCl+ QMİX /KŞİ, (4) NaOCl+EDTA/Pasif Ultrasonik İrrigasyon
(PUİ), (5) QMix/PUİ ve (6) QMix+NaOCl/PUİ. Oluklarda kalan KH miktarı 4
dereceli skorlama sistemi kullanılarak 25 büyütmede stereomikroskop altında
değerlendirildi. Veriler Kruskal–Wallis ve Mann–Whitney U istatistiksel
testleri kullanılarak değerlendirildi. Yapay standardize edilmiş oluklardaki
kalan KH miktarı tüm deneysel gruplarda gözlendi. PUİ/QMix+NaOCl ve
PUİ/NaOCl+EDTA diğer gruplara göre KH’i uzaklaştırmada daha etkiliydi (P < 0.05) ; fakat, PUİ/QMix+NaOCl ve
PUİ/NaOCl+EDTA grupları arasında istatistiksel olarak anlamlı fark bulunmadı (P
> 0.05). Diğer dört deneysel grup arasında KH’i uzaklaştırma bakımından
istatistiksel olarak fark bulunmadı (P > 0.05). İrrigasyon tekniklerinin
hiçbirisi, kök kanalının apikalindeki yapay standardize edilmiş oluktan KH’i
tam olarak uzaklaştıramadı.

EFFICACY OF QMIX IN REMOVAL OF CALCIUM
HYDROXIDE FROM ARTIFICIAL STANDARDIZED GROOVE IN APICAL ROOT CANALABSTRACT
The aim
of this study was to evaluate the efficacy of QMix in the removal of calcium
hydroxide (CH) from an artificial standardized groove in the apical root canal.
One hundred and eighteen extracted single-rooted canine teeth were prepared
using ProTaper system instruments up to size F5. The roots were split
longitudinally, and a standardized groove was prepared in the apical part of
one segment. The grooves were then filled with CH powder mixed with distilled
water, and the roots were reassembled. The roots were randomly divided into 6
experimental groups and 2 control groups, according to the following irrigation
methods: (1) conventional syringe irrigation (CSI) with sodium hypochlorite
(NaOCl) + ethylenediaminetetraacetic acid (EDTA), (2) CSI with QMix, (3) CSI
with QMix + NaOCl, (4) passive ultrasonic irrigation (PUI) with NaOCl + EDTA,
(5) PUI with QMix, and (6) PUI with QMix + NaOCl. The amount of remaining
medicament was evaluated under a stereomicroscope at 25 × magnification using a
4-grade scoring system. Data were evaluated using the Kruskal–Wallis and
Mann–Whitney U tests. Remnants of CH were found in all experimental groups.
PUI/QMix + NaOCl and PUI/NaOCl + EDTA were superior to the other groups (p <
0.05); however, there was no significant difference between the PUI/QMix +
NaOCl and PUI/NaOCl + EDTA groups (p > 0.05). There were no significant
differences between the other four experimental groups (p > 0.05). None of
the irrigation techniques completely removed CH from an artificial standardized
groove in an apical root canal.
