bony hard to palpate which later becomes rubbery and fluctuant.5,6 Radiographically, most radicular cysts appear as round or pear shaped unilocular radiolucent lesion in the periapical region. The cyst may displace adjacent teeth or cause mild root resorption and can even cause nerve compression. The treatment options for radicular cyst can be conventional nonsurgical root canal therapy when le...

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...

Central ossifying fibroma is a rare, benign fibro-osseous lesion that arises from the periodontal ligament. Periapical cemento-osseous dysplasia is another variant of fibro-osseous lesion which occurs in the anterior region of the mandible of females. Odontoma is a benign odontogenic tumor that contains enamel, dentine cement and pulp tissue. A 46-year-old woman was referred to the Department o...

Dens invaginatus is a developmental anomaly that results in an enamel-lined cavity intruding into the crown or root before the mineralization phase. This report presents regenerative endodontic treatment of a necrotic immature tooth with Oehler's type III dens invaginatus of a nine-year-old female patient. A diagnosis of dens invaginatus (Oehler's type III) and a large periapical lesion was est...

OBJECTIVES The aim of the present study was to compare the accuracy of intraoral digital periapical radiography and cone beam computed tomography in the detection of periapical radiolucencies in endodontically treated teeth. MATERIAL AND METHODS Radiographic images (cone beam computed tomography [CBCT] scans and digital periapical radiography [PR] images) from 60 patients, achieved from Septe...

background and aims. accurate differential diagnosis between radicular cysts and periapical granulomas cannot be made from radiographs alone. histological prevalence studies, therefore, assume special importance and may aid the clinician in making judgments regarding therapy. the incidence of radicular cysts has ranged with wide discrepancies in data. the purpose of this study was to evaluate r...

In this work we present a quantitative study on different regions of periapical images with a series of textural features, extracted using cooccurrence matrices; those features are used for a pattern recognition analysis by means of an artificial neural network. The obtained results show that it is possible to recognize in an objective way changes in bone pattern.

The implant periapical lesion (IPL), a possible cause for implant failure, may occur from the presence of pre-existing microbial pathology such as endodontic/periodontal lesions. This case report presents a case history related to IPL, which was caused by a pre-existing endodontic lesion. In addition, other possible causes such as surgical trauma and the management strategies of IPL are suggest...

This study aimed to evaluate the prevalence of mesiobuccal 2(MB2) canals not located/treated in maxillary molars and correlated their non-treatment with presence periradicular lesion. The was conducted on 180 cone beam computed tomography (CBCT) scans. examinations added up 210 teeth analyzed (140 first 70 second molars). non-located/treated MB2 periapical lesions mesiobucal(MB) root identified...

AIM The aim of this report is to present a case of Type III dens invaginatus in a maxillary lateral incisor with a periapical lesion and its successful treatment using a combination of surgical and non-surgical therapy. BACKGROUND The morphology of the root canal system is unique for individual teeth. A precise understanding of the morphology is very important for a successful root canal trea...
