Abstract

Background: Pathological changes in body architecture and disease progression can be detected with radiographs. Accurate diagnosis of this pathological process is necessary for successful treatment and for predictable outcomes. One of the recent advances in achieving this is the advent of diagnostic ultrasonography in identification and differentiating the periapical lesions. Aim of the study is to assess and compare the diagnostic capability of conventional radiography and colour Doppler ultrasound imaging in the identification and differentiating the periapical lesions.Methods: Twenty patients with periapical lesions of pulpal origin which were clinically diagnosed and indicated for extraction were selected for the study. Pre-operative periapical radiographs were obtained. Pre-operative ultrasound examination was performed and the images were assessed for the size, contents, vascular supply and to detect whether the lesion is a periapical abscess, periapical granuloma or periapical cyst. Extraction was performed including curettage of the periapical tissues to enable histopathological investigation, which provides the gold standard diagnosis. The results from the biopsies of the lesions were compared with radiological and ultrasound results and statistically analysed.Result: Of the twenty cases studied, ultrasound could detect 4 periapical abscess, 9 periapical Granuloma and 7 periapical cysts. But histopathologically there were 4 periapical abscess, 7 periapical granulomas and 9 periapical cysts. Two of the periapical cysts were misdiagnosed as periapical Granuloma ultrasonographically. Correlation between ultrasonography and histopathology is 90 percent and between conventional radiography and ultrasonography is 90 percent. Sensitivity of this examination is 88.89 percent.Conclusion: Ultrasound imaging has the potential to be used for the evaluation of periapical lesions of endodontic origin. However, further studies are required to establish a definite correlation.DOI:10.21276/AOHDR.2015
