dc.description.abstracteng	Objective: The purpose of this study was to evaluate the use of the tongue repositioning manoeuvre (TRM) during panoramic radiography so as to avoid the tongue shadow error. Study Design: A total of 300 panoramic radiographs were evaluated. One hundred and fifty orthopantomograms with conventional positioning technique were used as a control group, while other 150 were taken with the patient performing the TRM. The tongue shadow was measured in each radiograph in the first molar regions bilaterally and in the midsagittal plane. Wilcoxon Mann-Whitney U Test was used to test the significance difference between the groups. Results: The tongue-palate distance in the study group was reduced from a mean value of 6.4mm to 1mm in the right first molar, 8.0mm to 2.2mm in the midsagittal region and 6.6mm to 1.2mm in the left first molar position. Statistical evaluation exhibited significant differences of tongue shadow at all measuring sites between study and control group (p<0.0001). Conclusion: The present study demonstrates that the TRM leads to a substantial reduction of the tongue position error in panoramic radiography.	de
