Brief Summary

Post-endodontic pain (PP) still is major problem for endodontic patients, analgesics are routinely prescribed. Incidence of PP is reported extensively, and reviewed. PP is a complicated multi factorial process and is affected by factors related to patients, to the tooth and to the skills and experience of the dentist and because of that, if the interrelation of these factors is not considered in a PP, study data might be confusing. Any study trying to evaluate the effect of a specific technique or new device in the incidence or characteristics of PP should control all the confounding factors that have been described to be involved in the tested outcome.

reports mention a variable prevalence of PP, ranging from 82.9 to 10.6%. These variations are because of the differences in study methods, and treatment procedures after root canal treatment, selection of patients or experience and skills of the dentists, vary when different studies are compared.

Many studies had confirmed that chemomechanical debridement of the root canal results in extrusion of dentinal chips, pulp tissue fragments, necrotic tissues, microorganisms, and root canal irrigants through the apical foramen. All preparation techniques and instruments, regardless of maintaining shorter working length of the apical terminus have reported to be related with extrusion of infected debris, and some of them extruded less material and others extruded more.

Periapical inflammation and postoperative flare-ups may result from apical extrusion of debris that is also referred to as the "worm" of necrotic debris A common outcome of the studies examining the amount of apically extruded debris was that the techniques involving a push-pull filing motion usually produce a greater mass of apical debris than those have rotational action Files which has reciprocating and in-and-out filing motion, may act as a piston, extruding more debris and irrigants. While the file with continuous rotation motion like a screw conveyor improving transportation of dentinal chips and debris coronally.

In this study, investigators compare post-endodontic pain between these two systems. Mtwo ( continuous rotation system) with safe-sider (reciprocating system). Therefore, the aim of this study is Evaluation of post-endodontic pain after root canal treatment with two rotary systems: Mtwo \& safe-sider
