Abstract (2. Language): 
In this study, 62 extracted human teeth with single roots straight canals were used. Following pulp extirpation, the efficacy of NaOCl and the methods, in root canals irrigated with different volumes of 5.25% NaOCl at varying time periods using different needles were observed by SEM and stereomicroscope. , Except for two serving as controls, 60 teeth were equally divided into 4 groups. In groups 1 and 2, conventional and in groups 3 and 4 perforated needles were used. In groups 1 and 3, the root canals were irrigated with 30 cc 5.25% NaOCl for 3 min, and in groups 2 and 4 with 50 cc 5.25%> NaOCl for 5 min. 5 teeth from each group were irrigated with Pelikan ink either using the conventional or tre perforated needles and rendered transparent. SEM investigation revealedpulpal remnants in control teeth. All experimental groups showed the dissolution of the residual pulp tissue and cleansing of the canal surfaces. 50 cc-5 min 5.25% NaOCl irrigation also displayed the calcospheritic pattern. Some specimens showed pulpal remnants in the apical regions. Stereomicroscope observation of the cleared teeth revealed that both conventional and perforated needles were effective in distributing the dye throughout the entire length of the canals to within the 2-3 mm of the apical region. Dye was denser within the root canals irrigated with 50 cc 5.25% NaOCl for 5 min.

Abstract (Original Language): 
Bu araştırmada, 62 adet tek köklü-düz kanallı çekilmiş insan dişi kullanılmış ve pulpa ekstirpasyonundan sonra farklı yıkama İğneleri kullanılarak, farklı hacim ve sürelerde % 5.25 NaOCİ solüsyonuyla yıkanan kök kanallarında, NaOO'in ve yöntemin etkinliği SEM'de ve stereomik-roskop'da incelenmiştir. 62 dişin 2'sİ kontrol olarak ayrılmış, diğerleri 4 eşit gruba bölünmüştür. 1. ve 2. grupta geleneksel iğne; 3. ve 4. grupta ise delikli iğne kullanılmıştır. 1 ve 3. grupta, kök kanalları 30 cc % 5.25 NaOCİ ile 3 dak. süreyle; 2. ve 4. grupta ise, 50 cc % 5.25 NaOCİ ile 5 dak. süreyle yıkanmışlardır. Her gruptan beşer diş, geleneksel veya delikli iğne kullanılarak Pelikan mürekkebi ile yıkandıktan sonra şeffaflaştı-rılmışlardır. SEM incelemesinde, kontrol dişlerinde pulpa artıklarına rastlanmıştır. Bütün deney gruplarında İse, kalan pulpa dokusunun çözündüğü ve kanal yüzeylerinin temizlendiği; 50 cc-5 dak. % 5.25 NaOCİ uygulamasının kalsosferit yapıyı da ortaya çıkardığı izlenmiştir. Ancak, bazı örneklerin apikal kısımlarından pulpa dokusu tamamen uzaklaştırıla-mamıştır. Şeffaflaştırman dişlerin stereomikroskop incelemesinde; hem geleneksel hem de delikli iğnenin, apikal 2-3 mm'ye dek kanal uzunluğu boyunca boyayı dağıtmada etkin oldukları görülmüştür. 5 dak. 50 cc % 5.25 NaOCİ ile yıkanan dişlerde, kök kanalındaki boyanın daha yoğun olduğu izlenmiştir.
