Comparison of cyclic fatigue resistance of four pediatric rotary file systems at body temperature: an in vitro study.

Background: The aim of this study was to compare the cyclic fatigue resistance (CFR) of the newly developed pediatric nickel-titanium (NiTi) rotary file systems for root canal preparation of primary teeth.

Methods: Eighty pediatric NiTi rotary file systems files were used in this study, including 20 EasyInSmile X-Baby (25/0.04), 20 Scope miniScope (25/0.

The effect of compliance with PAP therapy on biochemical parameters in patients with obstructive sleep apnea syndrome: A 6-month follow-up study.

Introduction: The gold standard treatment for obstructive sleep apnea syndrome (OSAS) is positive airway pressure therapy (PAP) treatments. PAP treatments reduce complications by reducing apnea and hypopnea attacks by creating airflow at a determined pressure. In our study, we aimed to examine the effect of treatment compliance on kidney and liver functions, apneahypopnea (AHI) index, and lipid profile of patients diagnosed with OSAS and started PAP treatment.

Evaluation of the Relationship between FeNO and Clinical Risk Stratification for Early Mortality in Pulmonary Embolism.

Background: Pulmonary embolism (PE) is a common complication of deep vein thrombosis that causes high mortality and morbidity. This study aimed to determine the relationship between clinical risk scoring for early mortality and fractional exhaled nitric oxide (FeNO) in PE patients.

Methods: The study included a total of 98 subjects, 68 patients diagnosed with PE in the emergency department, and 30 healthy controls.

Evaluation of the value of exhaled carbon monoxide in the differentiation of viral and bacterial pneumonia.

This study compared exhaled carbon monoxide (CO) levels in patients hospitalized for bacterial and COVID-19-related viral community-acquired pneumonia. The study included a total of 150 patients: 50 patients hospitalized for COVID-19 between February 2021 and March 2022, 50 patients with bacterial community-acquired pneumonia and 50 healthy controls. In comparisons of exhaled CO levels among the groups, there was no significant difference between patients with bacterial pneumonia and controls, whereas patients with COVID-19 pneumonia had significantly higher exhaled CO levels compared with both the bacterial pneumonia and control groups (p < 0.

Evaluation of serum YKL-40 level among clinical risk scores for early mortality in acute pulmonary thromboembolism.

Introduction: Pulmonary embolism (PE) often occurs secondary to deep vein thrombosis and is an important cause of mortality and morbidity. This study aimed to evaluate the relationship between YKL-40 level and clinical risk score in patients with PE.

Methods: The study included a total of 100 patients, 80 patients diagnosed with PE in the emergency department and 20 healthy controls.

Evaluation of the Antibacterial Effects of Single and Combined use of Different Irrigation Solutions Against Intracanal .

Objectives: This study assessed the antibacterial activity of both separate and combined uses of 5.25% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX), 17% ethylenediaminetetraacetic acid (EDTA), 3% hydrogen peroxide (HO), MTAD, SmearClear (SC) and 13.8% chlorine dioxide (ClO) irrigation solutions against

Materials And Methods: Two hundred eighty single rooted human premolars were randomly grouped into 26 test and 2 control (negative and positive) groups and were incubated for 24 h with , except for the negative control group.

Comparison of organic tissue dissolution capacities of sodium hypochlorite and chlorine dioxide.

The organic tissue dissolution properties of irrigating solutions are important for the success of endodontic treatment. Chlorine dioxide (ClO2) has been recently proposed as an irrigation solution in endodontics. The organic tissue dissolution property of sodium hypochlorite (NaOCl) is well-known and extensively investigated, but apparently no data have been published on tissue-dissolving properties of ClO2.

Effect of immediate and delayed post preparation on apical microleakage by using methacrylate-based EndoREZ sealer with or without accelerator.

The purpose of this study was to evaluate the effect of immediate and delayed post space preparation on the apical sealing ability of EndoREZ, a methacrylate-based dual-cured resin sealer, with or without accelerator. Fifty extracted human teeth were endodontically prepared and randomly divided into 6 groups. Teeth in experimental groups 1, 2, 3, and 4 (n = 10) were filled with resin-coated gutta-percha and either EndoREZ with accelerator (A+) or EndoREZ without accelerator (A-) by the lateral compaction technique.

The effect of different restoration techniques on the fracture resistance of endodontically-treated molars.

Aim: This study compared the fracture resistance of endodontically-treated mandibular molars with mesio-occluso-distal (MOD) cavities restored using different restoration techniques.

Methodology: Sixty sound extracted mandibular molars were randomly assigned to six groups (n=10). Group 1 did not receive any preparation.
