In Vitro Comparison of Apical Mikroleakage of Primary Molars Prepared with Four Different Rotary Systems and K-Files

Abstract

The aim of this study was to evaluate apical microleakage of primary molars prepared with four different rotary systems and K hand files in vitro. Ninety primary molars were randomly divided into five experimental groups, which comprise 7 mandibular and 7 maxillary primary molars, and 20 teeth were selected as negative and positive control group each comprises ten teeth. Teeth were prepared with K file in Group 1, Race in Group 2, Protaper in Group 3, Hero 642 in Group 4 and with Mtwo in Group 5. Root canals of all teeth were filled with Endoflas F.S. Dye leakage test is used to assess apical microleakage and teeth were evaluated by clearing technique. In mandibular primary molars there was no statistical difference among the groups p>0,05 . In maxillary molars Race showed significantly higher dye penetration than Hero 642 and Mtwo p

Dört farklı döner alet sistemi ve k tipi eğe ile prepare edilen süt azı dişlerinde apikal mikrosızıntının in vitro olarak karşılaştırılması

Abstract

Dört farklı döner alet sistemi ve K tipi eğe ile prepare edilen süt azı dişlerinde apikal mikrosızıntının in vitro olarak karşılaştırılması. 90 adet süt azı dişi rastgele olarak, 7 alt ve 7 üst süt azı dişi olmak üzere 14 diş içeren 5 deney grubuna ve 10’ar diş içeren pozitif ve negatif kontrol grubuna ayrıldı. Dişler, 1. Grupta K- tipi el eğesi, 2. Grupta Race, 3. Grupta Protaper, 4. Grupta Hero 642 döner alet sistemi ve 5. Grupta Mtwo ile prepare edildikten sonra Endoflas F.S. ile dolduruldu. Apikal mikrosızıntının belirlenmesinde boya sızıntı testi kullanıldı ve dişler clearing metodu ile incelendi. Alt azı dişlerinde yapılan incelemede, mikrosızıntı değerlerinde istatistiksel açıdan anlamlı bir fark görülmemiştir p>0,05 . Üst azı dişlerinde yapılan değerlendirmede ise, Race grubunda mikrosızıntı miktarı Hero 642 ve Mtwo gruplarına göre anlamlı derecede yüksek bulunmuştur p
