INTRODUCTION An important consideration in endodontic treatment is the elimination of microorganisms, including fungi, from the complex three- dimensional root canal system. Candida Albicans (CA) has a major role in endodontic treatment failure as the most important fungus isolated from the root canal system. The present study was carried out to evaluate the presence of CA in the teeth requirin...

The pathogenesis of periapical lesions has not been fully elucidated. Currently, the possibility of its being an immunologic phenomenon is receiving much attention. This article presents a review of the literature concerning immunologic reactions which may involve periapical lesions. It appears that antigen-antibody complexes and IgE-mediated reactions can initiate preliminary changes in periap...

During the past few decades several authors have perpetuated the notion that nearly half of all periapical lesions are radicular cysts. A few studies, based on meticulous serial sectioning of periapical lesions retrieved in toto, have shown that the actual incidence of radicular cyst is only about 15% of all periapical lesions. Equally significant was the discovery in 1980 and recent confirmati...

OBJECTIVE To compare intraoral periapical radiography with 3D images for the diagnosis of periapical pathology. STUDY DESIGN Maxillary molars and premolars and mandibular molars with endodontic problems and examined with periapical radiographs and a 3D technique (3D Accuitomo) were retrospectively selected and evaluated by 3 oral radiologists. Numbers of roots and root canals, presence and lo...

INTRODUCTION Periapical inflammation is often responsible for distinct maxillary sinus (MS) changes. This retrospective, cross-sectional study evaluated the association between the clinical characteristics of periapical lesions (presence, size, and distance) in maxillary posterior teeth and the presence of sinus abnormalities by evaluating cone-beam computed tomographic (CBCT) images obtained f...

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...

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...

The objective of this study was to evaluate the expression of matrix metalloproteinase 9 (MMP-9) and transforming growth factor beta (TGF-β1) in periapical lesion samples correlated with the intensity of the inflammatory infiltrate and thickness of the epithelial lining. Forty-five cases of periapical lesions (23 periapical granulomas and 22 radicular cysts) were subjected to morphological and ...

BACKGROUND The prevalence of apical periodontitis in diabetes mellitus patients is high. The altered immunity in diabetes affects the healing process of periapical tissue. Single visit endodontic treatment has shown to increase the periapical healing rate with better patient compliance. Hence the present study aims at evaluating the clinical and radiographic healing outcome of single visit endo...

Periapical lesions develop as sequelae to pulp disease. Periapical radiolucent areas are generally diagnosed either during routine dental radiographic examination or following acute toothache. Various methods can be used in the nonsurgical management of periapical lesions: the conservative root canal treatment, decompression technique, active nonsurgical decompression technique, aspiration-irri...
