Abstract
Purpose
The variability of the EPT response threshold is the most important part of accurate diagnosis of pulp status of caries-affected resorbing primary teeth. This study evaluated the mean EPT threshold values and appropriate electrode placement sites for primary molar teeth based on their physiological root resorption levels.
Methods
This study was conducted with 100 primary second molars in 100 children ages 3–12 (mean age: 7.88 years). Teeth were divided into 2 groups according to physiological root resorption levels. EPT response thresholds were recorded at the mesiobuccal cusp, occlusal third, middle third and cervical third of the crown. Data were analyzed according to resorption level using one-way analysis of variance and Duncan tests, with the level of significance set at 0.05.
Results
Mean threshold values at all placement sites were higher in the group with the higher level of physiological root resorption. In terms of placement, the lowest mean EPT threshold values were obtained at the mesiobuccal cusp regardless of resorption level.
Conclusions
According to the study results, higher resorption levels were associated with higher physiologocial threshold values for EPT of primary second molars, with the mesiobuccal site identified as the most appropriate electrode placement site, regardless of resorption level.
