Objectives: Present study aimed to evaluate the roughening ability of different laser systems on the middle and apical third of roots.
Materials and Methods: Sixty extracted human single-rooted single canal mandibular premolar teeth were randomly assigned to 3 groups (n=20). Standardized preparation and sterilization procedures were performed. The samples were irradiated with Er:YAG, Nd:YAG, and KTP laser systems. The laser irradiations (1.5 Watt) were applied with a spiral motion, starting 1 mm short of the apex and then moving coronally for 10 sec, interleaved with 15-sec recovery intervals for each irradiation. This process was repeated twelve times. The roots that were standardized in the same length and thicknesses were divided parallel to the longitudinal axis. Then, the middle and apical 1/3 surface roughness values of each root section were measured using a profilometer and SEM analysis was performed. The data obtained were analyzed using the two-way analysis of variance (ANOVA) and Tukey post-hoc tests.
Results: According to measurements obtained from middle and apical 1/3 surfaces; Although, the statistically highest roughness value was determined after Nd:YAG laser (P < 0.05), the statistically lowest value was detected following the Er:YAG laser irradiation (P < 0.05).
Conclusions: In light of the present study, all laser systems caused significant roughness surface. Therefore, laser systems should be carefully applied in human root canals.

Amaç: Bu çalışma, köklerin orta ve apikal üçlüsünde farklı lazer sistemlerinin pürüzlendirme kabiliyetini değerlendirmeyi amaçlamıştır.
Gereç ve Yöntem: Altmış çekilmiş tek kök tek kanallı insan mandibular premolar dişler rastgele olarak 3 gruba ayrıldı (n=20). Standart preparasyon ve sterilizasyon prosedürleri uygulandı. Örnekler Er:YAG, Nd:YAG ve KTP lazer sistemleri ile ışınlandı. Lazerlerle ışınlama (1,5 Watt) apeksin 1mm yukarısından spiral hareketlerle başlanarak, koronale doğru 10sn boyunca uygulandı ve her ışınlama sonrası 15sn beklenildi. Bu prosedür 12 kez tekrarlandı. Eşit uzunluk ve kalınlıkta standardize edilen kökler dişin uzun aksına paralel olacak şekilde ayrıldı. Daha sonra, her kök kesitinin orta ve apikal 1/3 bölgelerinde meydana gelen yüzey pürüzlülük değerleri profilometer kullanılarak ölçüldü ve SEM analizi uygulandı. Elde edilen veriler, iki yönlü varyans analizi (ANOVA) ve Tukey post-hoc analiz testleri kullanılarak analiz edilmiştir.
Bulgular: Orta ve apikal 1/3 yüzeylerinden elde edilen ölçüm sonuçlarına göre; istatistiksel olarak en yüksek pürüzlülük değeri Nd:YAG lazer sonrası tespit edilmesine rağmen (p<0,05), istatistiksel olarak en düşük değer Er:YAG lazer ışınlama sonrasında tespit edildi (p<0,05).
Sonuçlar: Bu çalışmanın ışığında, tüm lazer sistemleri önemli ölçüde yüzey pürüzlülüğüne neden oldular. Bu nedenle, lazer sistemleri insan kök kanallarında dikkatle uygulanmalıdır.
