ABSTRACT:The purpose of this study is to evaluate the effect of coronal flaring on apical extrusion of debris using single file systems. Sixty freshly extracted human single-rooted mandibular incisor teeth were selected, and divided into four groups (n=15) as group 1- reciprocating system with coronal flaring (rewf), group 2- reciprocating system without flaring (rewof), group 3- rotary system with flaring (rwf), group 4- rotary system without flaring (rwof). Coronal flaring was performed in groups 1 and 3 with gates glidden drills (gg drills) (mani, japan) using sizes 1, 2, 3 upto a working length of 10mm. In rotary groups instrumentation was done using one shape files and in reciprocating groups wave one gold files are used. The experimental model described by myers and montgomery was used. Sixty eppendorf tubes were taken. The net weight of the dry debris per sample was calculated by subtracting the original weight of the empty eppendorf tube from the gross weight of the eppendorf tubes containing debris. The results obtained showed that Rotary single file system extruded less amount of debris than Reciprocating single files and Coronal flaring reduced the debris extrusion in both groups.
