BACKGROUND Periapical lesions occur in response to chronic irritation in periapical tissue, generally resulting from an infected root canal. Specific etiological agents of induction, participating cell population and growth factors associated with maintenance and resolution of periapical lesions are incompletely understood. Among the cells found in periapical lesions, mast cells have been impli...

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...

Ten milliliters of whole blood were withdrawn from 30 patients with one or more chronic periapical lesions measuring 10 x 10 mm or larger on radiographs taken before root canal therapy. Also, blood was withdrawn from 32 patients with known allergies (positive controls) and 30 individuals with no known allergies and no periapical or periodontal lesions (negative controls). The sera of the three ...

Most periapical lesions are associated with microorganisms from infected root canal systems. Maxillary sinus can pose a diagnostic dilemma radiographically because of its anatomical variation which can mimic a periapical pathosis. The aim of this study was to describe two cases of aberrant anatomical variation of the maxillary sinus that presented radiographic similarities to a periapical cyst ...

With dawn of era of minimal intervention in dentistry, surgical management of periapical lesions become controversial. Non-surgical or conservative management of periapical lesions not only cause less trauma to the tissues, but also promote faster and less eventful healing. This paper presents successful management of a periapical lesion in a 14 year old male child with calcium hydroxide paste ...

BACKGROUND Analyze the most important prognostic factors when performing periapical surgery and compare the success rates of distinct authors. INTRODUCTION Periapical surgery is an approach to treat non-healing periapical lesions and it should be viewed as an extension of endodontic treatment and not as a separate entity. MATERIAL AND METHODS A search of articles published in Cochrane, PubM...

background and aims. different clinical studies have reported high survival rates in immediate implant placement in extraction sockets with periapical lesions. the aim of this study was to investigate the effect of er:yag laser irradiation on success rate of immediate implant placement in tooth extraction sockets with chronic periapical lesions. materials and methods. thirty patients requiring ...

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...

Background and Aim: The main goal of root canal treatment is to prevent or treat apical periodontitis. The aim of the present study was to assess the coronal restoration status, root canal filling quality, periapical health condition, and related factors in endodontically treated teeth at the Dental Faculty of Islamic Azad University of Medical Sciences, Tehran, Iran, in 2011-12. Materials and...
