Aim: Debridement during root canal treatment is mandatory and it is provided by means of chemomechanical instrumentation and irrigation methods. This article analysis the debridement capacity of a novel system, SAF and its special irrigation device when used with different operation times in curved root canals. Methodology: 30 mesiobuccal root canals of maxillary molars were instrumented using SAF. Teeth were divided into three groups. In Group 1, 10 new SAF files were used for operation for 4 minutes. In Group 2, the 4-min previously used SAF files were operated in the same manner. In Group 3, the 8-min previously used SAF files were operated. During SAF operation 2.6 % NaOCl and 17 % EDTA were used alternately in all groups. Debris and smear layer removal were evaluated for the apical thirds under scanning electron microscope. Results: Non-used, 4-min preused, and 8-min preused SAF efficiently removed debris and smear layer in the apical thirds. There were no significant difference among the groups in terms of debridement. Conclusions: When SAF is operated in curved root canals with continous flow of irrigation it results in debris and smear-free canal walls in the critical apical thirds within 12 minutes.     How to cite this article: Yiğit Özer S, Adıgüzel Ö, Kaya S.

Aim: This study compared smear-layer and debris removal using with three different application times of 17% EDTA and 7% maleic acid irrigation agents. Methodology: Fifty-two maxillary and mandibular single-rooted teeth were divided randomly into seven groups (n = 8 each, control group n = 4). Three groups received 17% EDTA and three received maleic acid (1, 5, 10 min). Canals were prepared using nickel-titanium rotary files. Smear-layer and debris removal were evaluated in the coronal, middle, and apical thirds of the teeth using scanning electron microscopy, and results were analyzed compared using Mann–Whitney U tests. Results: Maleic acid removed the smear layer (coronal and middle: p<0.01; apical: p<0.05) and debris (all p< 0.05) more effectively than EDTA in terms of 1 min application period. Effectiveness did not differ significantly with 10-min applications. Conclusions: Final irrigation with 7% maleic acid is more efficient than 17%EDTA in the removal of smear layer and debris from the coronal, middle and apical third of the root canal system in application within 1 min.  How to cite this article: Kaya S, Adıgüzel Ö, Ganidağlı Ayaz S.
