A referred patient presented with a lesion of endodontic origin located at the apex of tooth #27. The tooth had been endodontically treated and re-treated. A periapical radiograph revealed a close relationship between the lesion and the maxillary sinus. A cone-beam computed tomography scan confirmed that the lesion had invaded the sinus cavity. The treatment plan consisted of periapical surgery...

Ameloblastoma is a benign tumor; whose importance lies in its potential to grow to enormous size with resulting bone deformity. Unicystic ameloblastoma (UA) is a less encountered variant of amelobastoma. The neoplastic nature of the lesion becomes evident only when the enucleated material is available for histologic examination. Although its predilection is for the posterior mandibular region, ...

It has been observed that the root canal treatment for the preservation of tooth having periapical pathology has shown over 90% of success whereas in the case where the canal is calcified, perforated, ledge is formed, and cases where symptoms still exist after treatment, endodontic treatment may not be the solution in attaining a successful treatment. Thus Apisectomy would generally be done to ...

The main aim of endodontic therapy is that the infected tooth returns to healthy and functional state. Surgical intervention is recommended only after nonsurgical techniques have failed. Calcium hydroxide paste is recommended as intra canal medicament because of its antimicrobial properties, tissue dissolving ability, inhibition of tooth resorption and indication of tissue repair by hard tissue...

background and aims. chronic periapical disease with pulpal origin is an inflammatory condition caused by bacterial infection. chronic infection could affect general health by increasing the production of cytokines such as interleukin-6 (il-6) that probably play a role in pathogenesis of pulpal and periapical diseases. the aim of the present study was a comparative evaluation of the level of se...

I i rbed o s ( a bstract alcium hydroxide [Ca(OH) 2] has been widely used hortor long-term intracanal antibacterial dressi aterial after endodontic treatment. In general w sed in endodontics, Ca(OH) 2 paste is composed of t owder, a vehicle, and a radiopacifier. To provide iopacity, barium sulfate (BaSO 4) powder is usual dded to the paste. In this case report, BaSO 4:Ca(OH)2 owders (ratio 1:8)...

INTRODUCTION Bacterial infection of tooth pulp can progress into periapical diseases. Root canal treatment has been established as the best treatment. In cases of failure, nonsurgical retreatment of teeth is preferred to surgical procedure and extraction. MATERIALS AND METHODS In this historical cohort study, 104 permanent teeth with apical lesion were treated during 2002-2008. All teeth show...

this study was perfomed on twenty five teeth which showed radiographic lesions( 6mm over 25 mm). the teeth were arranged in seven different groups and root canal therapy ( by warm gutta-percha technique) as surgical intervention were performed at various time intervals. in this investigation, histologic studies of the periapical tissues begin shortly after elimination of the root canal system w...

The implant periapical lesion is the infectious-inflammatory process of the tissues surrounding the implant apex. It may be caused by different factors: contamination of the implant surface, overheating of bone during drilling, preparation of a longer implant bed than the implant itself, and pre-existing bone disease. Diagnosis is achieved by studying the presence of symptoms and signs such us ...
