Summary

The aim of this study was to evaluate the effect of simultaneous length control during root canal preparation on postoperative pain compared with separate working length determination and root canal preparation using electronic apex locator. During preparation of root canals, loss of working length (WL) can lead to instrumentation beyond the predefined apical limit of the preparation. This effect is mainly attributed to straightening of the root canal during instrumentation. Some studies showed, that this kind of over instrumentation as well as under instrumentation can adversely affect the outcome of the endodontic treatment, while it remains uncertain what exactly is the most favorable extent of the apical limit of root canal preparation. Furthermore, all endodontic instruments produce apical extrusion of debris, even when the preparation is kept within the confines of the root canal. Consequently, preparations ending in the periapical tissue will produce a greater amount of debris extrusion that could elicit a neurogenic inflammatory response resulting from an irritation of the periodontal ligament with subsequent postoperative symptomatic apical periodontitis. Therefore, it seems favorable to control the determined WL during root canal preparation to avoid preparations ending in the periapical tissue.

Conditions

  • Postoperative Pain

Interventions

PROCEDURE

simultaneous working length control using E-CONNECT S

E-CONNECT S (Eighteeth medical technology Co., Ltd, china) is an endomotor with integrated apex locator newly introduced in the market with continuous WL measuring function. It contains an optional module for rotary instrumentation, allowing the device to function as a low-speed handpiece, apex locator, or a combination of both. This motor has an attention-grabbing property that when an instrument reaches the predetermined working length, the motor automatically stops the instrumentation. Thus, it can be concluded that automatically stopping instrumentation when the instrument reaches the working length would decrease postoperative pain compared with manually controlling the working length by using stoppers during instrumentation (separate length determination and root canal preparation).

PROCEDURE

separate length determination and root canal preparation using Root ZX apex locator.

Using manual control of the working length by using stoppers during instrumentation (separate length determination and root canal preparation) using Root ZX apex locator.
