Amaç: Bu çalışmanın amacı, ProTaper Next eğelerinin farklı tork ayarlarının mikro çatlak oluşumuna etkisini değerlendirmektir. Gereç ve yöntemler: Doksan adet alt çene anterior diş kullanıldı. On beş diş kontrol olarak, 75 diş ise tork ayarlarına göre (n=25) üç gruba ayrıldı. 1. grupta; kök kanalları ProTaper Next eğeleri kullanılarak 300rpm dönüş hızında ve 2.0 Ncm torkta enstrümante edildi. 2. grupta; eğeler 3.5 Ncm torkla ve grup 3'te; eğeler 5.2 Ncm tork ile kullanıldı. Dişler yatay olarak 3, 6 ve 9 mm'de kesildi ve stereomikroskop ile incelendi. Bulgular: Toplam kırık diş yüzdesi 2.0, 3.5 ve 5.2 Ncm gruplarında, anlamlı bir fark olmaksızın sırasıyla %24, %28 ve %32 olarak kaydedildi (p>0.05). Sonuç: ProTaper Next eğelerinin yüksek tork ayarlarında kullanılması, mikroçatlak oluşum miktarını anlamlı olarak etkilememektedir. Klinisyenler, klinik deneyimlerine dayanarak üreticilerin önerdiği farklı tork değerlerinde döner sistemleri kullanabilirler.

Aim: The purpose of this study is to evaluate the effect of different torque settings of ProTaper Next files on microcrack formation. Materials and methods: Ninety mandibular anterior teeth were used. Fifteen teeth served as control and 75 teeth were divided into three groups according to the torque settings (n=25). In group 1; the root canals were instrumented using ProTaper Next files at a rotational speed of 300rpm and 2.0 Ncm torque. In group 2; the files were used with 3.5 Ncm torque, and in group 3; the files were used with 5.2 Ncm torque. Teeth were horizontally sectioned at 3, 6, and 9 mm and examined with a stereomicroscope. Results: The percentage of total cracked teeth in the 2.0, 3.5, and 5.2 Ncm groups were recorded at 24%, 28%, and 32%, respectively, without any significant difference (p>0.05). Conclusion: The use of ProTaper Next files with high torque settings did not affect the amount of microcrack occurrence. The clinicians may use the rotary systems within different torque values suggested by manufacturers in reliance upon their clinical experiences.
