Role of ultrasound and color doppler in diagnosis of periapical lesions of endodontic origin at varying bone thickness.
OBJECTIVE
To access the role of ultrasound and color doppler in diagnosing periapical lesions of maxilla and mandible.


METHODS
This study was conducted in the Department of Conservative Dentistry and Endodontics (Faculty of Dental Sciences), Department of Radiotherapy, and Department of Pathology.


METHODS
The study group comprised 30 patients with periapical lesions of endodontic origin in maxilla and mandible requiring endodontic surgery. After thorough clinical and radiographic examination patients were subjected to ultrasound and color doppler examination, where the lesions were assessed for their contents as to cystic or solid. Following which periapical surgery was done and the pathological tissue obtained was subjected to histopathological examination. The results of the ultrasound examination were correlated with histopathological features. The diagnostic validity of ultrasound was assessed by calculating the sensitivity, specificity, positive predictive value, and negative predictive value.


METHODS
The statistical analysis was done using statistical package for social sciences (SPSS) version 15.0 statistical analysis software. The values were represented in number (%).


RESULTS
Within the limitations of the current study it can be stated that although ultrasound may not establish the definitive diagnosis, it can facilitate the differential diagnosis between cystic and solid granulomatous lesions. However, this technique may have a limited role in detecting periapical lesions present in the region with thick overlying cortical bone.


CONCLUSIONS
Ultrasound can routinely be recommended as a complimentary method for the diagnosis of periapical lesions of endodontic origin. However, this technique may have a limited role in detecting periapical lesions present in the region with thick overlying cortical bone.
