The aim of this study was to determine the levels of proinflammatory tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) cytokines in whole unstimulated saliva in subjects with burning mouth syndrome (BMS) before and after treatment with low-level laser therapy (LLLT). BMS is characterized by a continuous, painful burning sensation in a clinically(More)
AIM The aim of this study was to evaluate the presence of the cytokines tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in human periapical lesions. SUBJECTS AND METHODS Samples were obtained from three groups of teeth: symptomatic teeth, asymptomatic lesions, and uninflamed periradicular tissues as a control. RESULTS TNF-alpha levels(More)
OBJECTIVE Oral lichen planus (OLP) is chronic inflammatory disease of the oral mucosa, presenting in various clinical forms. The etiology of OLP is still unknown but mounting evidence points to the immunologic basis of this disorder. AIM Our study was undertaken to quantify the salivary levels of pro-inflammatory tumor necrosis factor-alpha (TNF-alpha) in(More)
The aim of this in vitro study was to compare the sealing effectiveness of the Erbium:YAG laser to the sealing effectiveness of an ultrasonic device in the preparation of similar retrograde cavities using different retrograde filling materials. After root-canal instrumentation and filling, apices of 60 single-rooted teeth were resected. Retrograde class I(More)
Severe xerostomia is a common late radiation consequence, which occurs after irradiation of head and neck malignancies. The aim of the present study was to analyze apoptosis and proliferation and their relationship during the late post-irradiation phase. C57BL/6 mice were locally irradiated in head and neck region with a single dose of 7.5 or 15 Gy and(More)
BACKGROUND The aim of this study was to determine concentrations of tumor necrosis factor-alpha (TNF-alpha) in normal, painful, and asymptomatic human dental pulps. METHODS Pulps were obtained from three groups of teeth, including healthy teeth, asymptomatic teeth with caries and/or large restoration, and symptomatic teeth with clinical diagnosis of(More)
The aim of this study was to determine the salivary concentrations of tumour necrosis factor α (TNF-α) and interleukin 6 (IL-6) in patients with premalignant and malignant lesions. The study involved 57 patients who were examined between 2008 and 2010 at the Department of Oral Medicine and Department of Oral and Maxillofacial Surgery of the Medical Faculty,(More)
AIM The aim of this study was to examine the apical sealing ability of five root canal sealers using a fluid transport model. METHODOLOGY A comparison of root canal scalers AH26, AH Plus, Diaket, Apexit, and Ketac-Endo were tested on 60 single-rooted teeth. The coronal part of each tooth was removed at the amelo-cemento junction, and also 3 mm of the root(More)
The calcium hydroxide-based filling material Apexit, which is often used in endodontic practice, was evaluated for its antibacterial and antifungal effects against microorganisms isolated from oral cavity (Serratia marcescens, Pseudomonas putida, Staphylococcus aureus, Candida albicans). Two different quantitative techniques were employed—the direct-contact(More)
The etiology of BMS remains unknown. Role of various cytokines has been implicated in the development of BMS. The aim of this study was to evaluate levels of salivary IL-2 and IL-6 in patients with BMS, compared with age-matched healthy volunteers (control group). Whole saliva from 30 patients with BMS, age range 55-65, was tested for the presence of IL-6(More)
