Amaç: Bu çalışmanın amacı irrigant aktivasyonu
sırasında kullanılan sonik uçların boyutunun ve titreşim sıklığının irrigant
taşmasına etkisini incelemektir.

Gereç ve Yöntem: Bu çalışmada 20 adet yapay üst molar diş
modeli kullanıldı. Bu diş modellerinin palatinal kanalları apikal çap #40
olacak şekilde genişletildi. Periapikal lezyonu taklit etmek için her bir diş
modeli salin solusyonu ile dolu cam şişelere yerleştirildi ve 10^-5 g hassasiyetindeki hassas tartı ile
ilk ağırlıkları ölçüldü. Sonrasında sonik ucun boyutu (15/.02, 25/.04,
35/.04) ve uygulama modu/hızı (düşük, orta, yüksek hız) esas alınarak irrigasyon protokolleri uygulandı. Kontrol grubunda irrigasyon
herhangi bir sonik uç kullanmadan iğne
ucunun giriş kavitesinin girişinde tutulması ile gerçekleştirildi. Apikalden
taşan irrigant miktarı, test düzeneğinin başlangıç ağırlığının final ağırlıktan
çıkarılmasıyla hesaplandı. Veriler Kruskal-Wallis ve Siegel Castellan testleri
analiz edildi.

Bulgular: Kontrol grubuna kıyasla, 15/.02
uçlar sadece yüksek hızda daha fazla irrigant taşmasına yol açarken, 35/.04
uçlar düşük hızda neden oldu (p
< 0.05). 25/.04 uçlar tüm hızlarda kontrol
grubuna göre daha fazla irrigant taşması ile sonuçlandı (p < 0.05). Yüksek
hızda 15/.02 ve 25/.04
uçlar, 35/.04 uç kullanımına göre daha fazla
irrigant taşmasına neden oldu (p < 0.05).

Sonuçlar: Sonik aktivasyon sırasında kullanılan sonik
ucun hem çapı hem de titreşim sıklığı irrigant taşma miktarını anlamlı ölçüde
etkilemektedir.

Effects of size and operating mode of sonically oscillating files on irrigant extrusion

Objective: The purpose of this study was to
evaluate the effects of size and oscillation frequency of sonic tips on
irrigant extrusion during activation.

Materials and Methods: Twenty artificial maxillary molar tooth
models were used in this study. The palatinal canal of each model was
prepared up to final apical size of #40. Each specimen was mounted
on a glass vial filled with saline solution to simulate a periapical lesion.
The mean initial weights were measured using an
analytical balance with 10^-5 g accuracy. Then, a series of
irrigations were conducted according to the size (15/.02, 25/.04, 35/.04) and
operating mode/speed (low, medium, high) of the sonic tips. In control group, the irrigant was delivered by
placing the needle tip at the access cavosurface, without the insertion and
activation of the sonic
tip. The mean weights of apically extruded irrigant were calculated by
subtracting the mean initial weights from the final weights of test apparatus.
Data were statistically analyzed by the Kruskal-Wallis and Siegel Castellan
tests.

Results: The use of
15/.02 tips resulted in higher irrigant extrusion than the control only
at high speed while the 35/.04 tips only at
low speed (p < 0.05). The 25/.04 tips
presented higher extrusion than the control with all operating modes (p <
0.05). At high speed mode, both the 15/.02 and
25/.04 tips were associated with higher
irrigant extrusion than the 35/.04 tips (p <
0.05).

Conclusions: Both the size and oscillation frequency
of the sonic tips had significant effects on extrusion during sonically
activated irrigation.
