Flowmetric values have been used to accurately identify the reestablishment of vitality in traumatized teeth.6-8 Data on PBF values in children with traumatized immature permanent maxillary incisors is scarce, with two traumatized immature teeth in a single patient.9 Therefore, the current study aimed to evaluate the effect of extrusion on immature permanent tooth PBF values during a 6-month post-trauma period and to compare the accuracy of cold tests on pulp sensibility of traumatized teeth with that of electric pulp tests
The tooth was nonresponsive to cold testing and electric pulp test
. Radiographic examination revealed an immature tooth and radiolucent lesion at the periapical area of the root (Figure 1).
Electric pulp test
and heat and cold test with temporary stopping of GP points were carried out.
LDF is more reliable as compared to pulseoximetry and electric pulp test
[Karayilmaz and Kirzioglu, 2010] or to classic 'sensitivity testing'.
