RESUMO

Ultrasound (US) is routinely used for evaluation of soft tissues; however it is a method that has important features to evaluate not only these tissues, but also hard tissues that could help in the treatment planning and prognosis. This study analyzed the possibility of evaluation of intra-osseous changes, by means of US; grounded in this premise. The sample consisted of five macerated pig jaws, and the third molars areas (both the right and the left, totaling 10 ratings) were evaluated as these regions have a significant bone crypt, which simulate an intra-osseous lesion. For ultrasound images assessments two groups of three observers were trained, one of dentists (Radiology specialists) and other of physicians (US specialists), which evaluated individually, the visualization of the image obtained by US, and also the translucency degree of the bone. Dentists have been considered 46.6% of the assessments of easy viewing; 13.3% were considered of medium difficulty; 23.3% were classified as very difficult, although 16.6% were not found. Physicians considered 43.3% of images of easy viewing; 23.3% were considered of medium difficulty; 20% were classified as very difficult, although 13,3% were not found. Based on this results and the literature findings, it is possible to conclude that US is a useful tool for assessment of intraosseus cavities, but cortical bone should be thin so the sound waves can penetrate. US is an imaging method easy to perform and interpret, as the dentists, who had no access or familiarity with US, could interpret its images, at a slightly lower level than the US specialists, which can be explained by greater experience by these professionals. More studies should be conducted in order to explore the potential benefits and advantages of US utilization in Dentistry.
