Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
A total of 30 infected mandibular primary second molar teeth in twelve children aged between 5 and 8 years were included in this study. Working length determination was performed using tactile sense, radiographic method and two different varieties of electronic apex locators (ProPex Pixi® and Ipex®) separately.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
For working length determination, the groups were performed as; Group 1: Tactile Sense Method Group 2: Radiographic Method (digital periapical radiography) Group 3: Ipex® EAL Group 4: Propex® pixi EAL The measurement techniques given in the groups were used in each root canal of all primary molars (n=90).
Root canal length determination by tactile sense method:
In the determination of working length using tactile sense, a K-file with the tip that best adjusted to the apical area was selected and gently inserted into the canal until the operator felt the narrowest region. The silicone stop was then placed at the coronal reference, and tooth length considering the end of the root was measured with an endodontic ruler (0.5mm accuracy).
Root canal length determination by radiographic method:
In group 2, working length determination was performed with digital periapical radiograph (……………….). Before the radiographic evaluation, the protective thyroid lead and protective lead apron were used for all children. Digital periapical radiograph was taken with using paralleling technique while the files were in the canals. X-ray positioning device (FPS 3000-Film positioning system complete, TPC Advanced Technology Inc., California, USA) was used to standardize the distances between the source and the tooth, and the tooth and the film. Cusp adjacent to the canal was taken as the occlusal reference. Files, 1 mm shorter than the tooth length as recorded according to the preoperative radiograph, were inserted in the canals. The difference between the tip of the file and the end of the root was calculated on the image. In case the file had not passed the apex, this amount and the original length was calculated. In case the file had passed the apex, the amount was subtracted from the original length. Lastly, 1 mm was subtracted from this adjusted length to confirm the cemento-dentinal junction and recorded as radiographic working length.
Root canal length determination by EALs:
The electronic working length determination was performed either with Ipex®/Goup 2 (NSK Ltd, Tokyo, Japan) or ProPex Pixi®/Group 3 (Dentsply Maillefer, Ballaigues, Switzerland) apex locators. Lip clip was attached to patients' lower lip in order to complete the circuit. Then, the root canals were moistened with 0.9% saline solution, and a no.15 K- file (Dentsply Maillefer, Baillaigues, Switzerland) mounted to the holder was gently inserted till "0.5" signaled on the screen, meaning that the tip of file was at the apical constriction. If the reading was stable for at least 5 seconds, the file was pulled back and the length between the silicone stopper and the tip of the file was measured with an endodontic ruler.
Endodontic treatment was completed in same appointments.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Tactile Sense Method
In clinical practice, tactile sense and conventional radiography have been the methods of choice for determination of working length for a long time. However, these two methods have some limitations in determining working length. While the accuracy rate in tactile sense changes with experience, radiographic examination in children is usually hard due to poor cooperation or the unsuitable sensor size for child's small mouth \[7\]. Also, these techniques may yield inaccurate information especially in cases with root resorption

Ipex® EAL
Electronic apex locaters (EALs), which are based on electrical principles instead of visual determinants, have been used more frequently in primary teeth.
