The purpose of this in vitro study was to assess the amount of apically extruded debris during the root canal preparation using different rotary instrumentation systems and different irrigants.
In this study, 80 human mandibular first premolars were randomly assigned to 4 groups (n = 20 teeth/group). Each group was then divided into four subgroups. In each group, the root canals were instrumented according to the manufacturer's instructions using the Protaper, Mtwo, K3 and full-sequence rotary Hyflex CM instruments. The canals of sub groups of each group were irrigated with four different irrigants: sodium hypochlorite, chlorhexidine and normal saline. Preweighed eppendorf tubes were used to collect the debris that extruded apically which was assessed with an electronic balance and compared.
Protaper demonstrated maximum extrusion, while hyflex demonstrated least extrusion compared to other experimental groups and 5% Sodium Hypochlorite in each group demonstrated maximum extrusion, while Normal saline in each group demonstrated least extrusion.
Under the conditions of this study, it can be concluded that all systems extruded debris beyond the apical foramen.
