Many studies have been reported on radiographic lesion sizes of periapical lesions. However no studies have been reported on prevalences of subjective radiographic features in these lesions except for the early assumption that a periapical cyst usually exhibit a radiopaque cortex. This study is conducted to evaluate the prevalences of several subjective radiographic features of periapical cysts...

INTRODUCTION The aim of this study was to investigate radiographically the relationship of tobacco smoking and periapical status by using a retrospective case-control study design. METHODS The records of 79 controls and 79 age- and sex-matched cases were examined. Case was defined as a patient who has at least 1 radiographically detectable periapical lesion in a tooth. Control was defined as ...

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...

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...
