background and aims. with the introduction of cone beam computed tomography (cbct) in dentistry, a question has been raised whether the technique significantly increases the diagnostic accuracy in comparison with other techniques or not. therefore, the present study was undertaken to assess the accuracy of cbct modality in detecting proximal carious lesions as compared to conventional periapica...

AIM To investigate the expression and immunohistochemical localization of leptin receptor (LEPR) in human periapical granulomas. METHODOLOGY Periapical inflammatory lesions were obtained from extracted human teeth and teeth which underwent periapical surgery. After their histopathological categorization as periapical granulomas (n = 20), they were examined by immunohistochemistry using human ...

OBJECTIVE The purpose of this study was to evaluate the distribution of microorganisms in the root canal system (RCS) and periapical lesions of dogs' teeth after rotary instrumentation and placement of different calcium hydroxide [Ca(OH)2]-based intracanal dressings. MATERIALS AND METHODS Chronic periapical lesions were experimentally induced in 80 premolar roots of four dogs. Instrumentation...

Objective. Photodynamic therapy has been expanded for use in endodontic treatment. The aim of this study was to investigate the antimicrobial effects of diode laser irradiation on endodontic pathogens in periapical lesions using an in vitro apical lesion model. Study Design. Enterococcus faecalis in 0.5% semisolid agar with a photosensitizer was injected into apical lesion area of in vitro apic...

The cell distribution and the tissue composition of chronic inflammatory periapical lesions were analyzed from seventeen biopsies of root-filled maxillary canines and incisors. The specimens, which included the root tip, the soft granulation tissue, and portions of the surrounding alveolar bone, were subjected to a stereologic analysis based on morphometric point-counting procedures. Plasma cel...
