Brief Summary

The aim of this study was to evaluate the effectiveness of tactile sense, digital periapical radiograph and two different varieties of electronic apex locators at working length determination in primary molars. 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.

Conditions

Endodontically Treated Teeth; Primary Teeth; Pulp Necroses

Outcome Measures

Primary Outcomes (1)

• Determination of root canal working length

  Data were collected from measurements taken from each primary molar's root canal working length. 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. After collection of the data, measurements taken from each root canal measurement method were compared.

Study Arms (4)

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.
