Aim:
This study describes the use of a real time-ultrasound imaging technique (echography) for the study of periradicular lesions.
Methodology:
Twelve patients with periapical lesions of endodontic origin, diagnosed with conventional clinical and radiographic examination, were examined further using echography at the site of the diagnosed lesions. Each lesion was echographically characterized and described by an expert echographist together with an endodontist. Once the major echographic features were identified, information on the size of the lesion, its content, and its vascular supply was obtained and recorded. A tentative differential diagnosis between a cyst and a granuloma was made based on the data.
Results:
In all cases it was possible to obtain an echographic image. It was also possible to measure the lesions, to evaluate their content and to view their vascularization in different regions of the mouth.
Conclusions:
Ultrasound real time imaging is a promising diagnostic technique in endodontology, but further work is required to refine the process.
