long-term success of endodontic treatment is precisely and completely dependent on adequate and appropriate cleaning and shaping of the root canal along with proper and correct obturation of the entire prepared space. this paper aims to report an exceptionally and novel non-surgical and orthograde endodontic therapy on maxillary right central incisor with an extensive radiolucent lesion. a 17-y...

Isotopic bile salt studies were carried out in eight middle-aged women with radiolucent galstones in functioning gallbladders and in 10 matched controls. In the gallstone patients the size of the bile salt pool was reduced by 37% to 1.79 g, but there was considerable overlap with the normal subjects. The cholate and chenodeoxycholate pools were reduced, but the deoxycholate pool was normal in s...

The literature on radiolucent lesions in unerupted permanent teeth is reviewed with particular attention to etiology. A case is presented which demonstrates severe coronal destruction of a mandibular second permanent molar. Histological evidence also is presented to confirm diagnosis of external resorption. Based on previous literature and the results of this case, the authors conclude that the...

Adenomatoid odontogenic tumor (AOT) is a rare noninvasive odontogenic tumor that occurs mostly in the second decade of life. Based on its tooth association, AOT can be classified into three categories of follicular, extrafollicular, and peripheral types; the follicular classification is considered as the most common type of AOT. This study reported a large extrafollicular case of AOT in a 40-ye...
