Aims and Objectives: Due to the importance of relating radiographically the position of the tongue with structures of the buccal cavity, and its relation with the skull.

Objective: The purpose of this study was to verify the effectiveness of a radiographic contrast paste based on barium sulfate.

Method: Radiographs were obtained: skull macerated, tongue of pig, 5 ml syringe containing the paste, needle for spinal anesthesia. The lateral teleradiographies were obtained with variation of the factors and alteration of the position of the tongue.

Results: Radiographically, the pulp showed to be effective even when increased kVp and mA factors were used and it was possible to observe and determine the different positions of the tongue.

Conclusion: Within the laboratory conditions, the barium sulphate pulp presented adequate radiopacity, adequate viscosity, easy dispensing, compatibility with the lingual tissue and low cost.
