Abstract

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.
