In the oral cavity, extranodal non-Hodgkin's lymphoma can occur in the periapical region either in the maxilla or mandible. Also, it can mimic inflammatory lesions that arise around the teeth apices such as periapical granuloma, radicular cyst and osteomyelitis. Misdiagnosis of lymphomas in the jaws may reduce the chance of successful treatment and worsen the prognosis. Therefore, any growth of...

Management of a tooth with open apex is a challenge to the dental practitioners. Evaluation of the periapical healing is required in such cases by radiographic techniques. The objective of this paper was to assess the healing of a periapical lesion in a non-vital tooth with open apex treated with mineral trioxide aggregate (MTA) obturation using cone beam computed tomography (CBCT). The endodon...

PURPOSE To investigate implant periapical lesions, and to describe their treatment. The hypothesis of this evaluation is that implant periapical lesions are disorders of the area surrounding the apex of a dental implant, and that their etiology can be multifactorial (ie, vascular impairment, vascular ischemia, overheating of bone during drilling, and implant surface contamination). The diagnosi...

OBJECTIVE This study evaluated experimentally-induced periapical bone loss sites using digital radiographic and histopathologic parameters. MATERIAL AND METHODS Twenty-seven Wistar rats were submitted to coronal opening of their mandibular right first molars. They were radiographed at 2, 15 and 30 days after the operative procedure by two digital radiographic storage phosphor plates (Digora®)...

AIM To report a case of conservative nonsurgical management of periapical lesions. BACKGROUND Small periapical lesions of endodontic origin usually heal by conventional endodontic therapy alone. Larger periapical lesions presumed to be cystic may require additional treatment protocols to aid in regression. Conservative nonsurgical management of such lesions eliminates the possible complicatio...

Quantitation of circulating immune complexes (CIC) was done in 45 patients with chronic periapical lesions. The levels were compared with those of age-matched healthy individuals. Both patients with chronic periapical granuloma and periapical cysts showed significantly higher levels of CIC than the controls. This observation indicates that the continuous presence of root canal antigens may caus...

Periapical radiography is essential in diagnosis, treatment planning and follow-up in endodontics. However, image interpretation can be confounded by geometric distortion, superimposition of regional anatomy and technique errors. These problems can be overcome by utilizing small or limited-volume cone beamcomputed tomography imaging techniques, which produce accurate 3-D images of the teeth and...

Radicular lingual grooves are morphological defects, which are found most frequently in maxillary anterior teeth and are a predisposing factor for periodontal disease. They are easily overlooked as aetiologic factors, as these grooves are covered by periodontal tissues. This case report presents a successful management of a case of a maxillary lateral incisor with an associated radicular lingua...

AIM To report the non-surgical management of a large periapical lesion. SUMMARY Surgical treatment of large periapical lesions is often subject to various complications. Hence, a non-surgical approach should be considered for the management of these lesions. The traditional aspiration technique involves creation of buccal and palatal wounds that can cause considerable discomfort for the patie...

Maxillary sinus can pose diagnostic dilemma radiographically because of its anatomical variation which can mimic a periapical pathosis. This case report deals with one such diagnostic problem, where a maxillary sinus was interpreted in an intraoral periapical radiograph as a periapical cyst. With the advances in imaging techniques, the use of an Ultrasound imaging together with application of C...
