Brief Summary

Precise knowledge of the apical construction, which determines the end of the area for canal preparation and filling, is essential for the success of root canal treatment and the management of postoperative pain. For this purpose, devices based on various methods that determine the working length are used. However, it is still controversial which method provides the most accurate measurements.In this study, the compatibility of the electronic apex locator (EAL) and simultaneous working length determination (SWL) methods in single-root teeth was investigated in comparison with the radiographic working length determination method (RWL) method, and to determine which one produced more effective results in terms of postoperative pain.A hundred patients applied for endodontic treatment with a diagnosis of irreversible pulpitis (IP) were included in the study, which was planned as a single-center prospective cohort. Patients were divided into three groups according to the method used to determine the root canal working length (WL). 35 patients in whom the WL with EAL method (EWL) was used were included in Group 1; 35 patients in whom the SWL method was used were included in Group 2; 30 patients in whom the RWL method was used were assigned to Group 3. Patient groups were randomly selected from people similar in age and gender. Age, gender, simplified oral hygiene index (OHI-S), oral and dental examinations and Visual Analogue Scale (VAS) results of all participants were recorded.

Detailed Description

Devices that apply various methods to determine the root canal working length have been developed. The simultaneous working length determination is a newer development that allows clinicians to clean and shape root canals while monitoring the file's position inside the canal using dynamic feedback from EAL. In this method, an endodontic motor with a built-in EAL that provides continuous feedback during root canal instrumentation and allows clinicians to make real-time adjustments to the WL. Thus, it provides continuous feedback, allowing the clinician to make real-time adjustments. The motor of devices using this method has automatic apical reverse and automatic apical stop operation. In this way, when the tip of the file reaches the apical foramen, the file safely reverses and stops rotating. Thereby, SWL method reduces the risk of over- instrumentation. In this study, planned in the light of the above information, the aim of this study was to investigate the compatibility of the EWL and SWL methods in single-root teeth, in comparison with the RWL method, and to determine which one produces more effective results in terms of postoperative pain.

Study Groups

Electronic working length method

Electronic apex locator was used

Group Type: EXPERIMENTAL

EWL

Intervention Type: DEVICE

the working length determination with EAL method

Simultaneous working length method

Working length was determined by EAL and then during root canal preparation, an endodontic motor using simultaneous working length control was selected

Group Type: EXPERIMENTAL

SWL

Intervention Type: DEVICE

In this method, an endodontic motor with a built-in EAL that provides continuous feedback during root canal instrumentation and allows clinicians to make real-time adjustments to the WL. Thus, it provides continuous feedback, allowing the clinician to make real-time adjustments. The motor of devices using this method has automatic apical reverse and automatic apical stop operation. In this way, when the tip of the file reaches the apical foramen, the file safely reverses and stops rotating.

Radiologic working length method

30 patients in whom the radiologic working length (RWL) method. In this method, periapical radiographs were taken.

Group Type: PLACEBO_COMPARATOR

RWL

Intervention Type: DEVICE

Radiographic method was used for determining the working length
