Sampling of salivary cortisol and amylase is a non-invasive method and important for the evaluation of the hypothalamic-pituitary-adrenal axis function and stress levels. This study aimed to compare the values of the salivary cortisol and amylase levels which were measured by three different analytical methods to discuss the alterations of stress levels of samples. The saliva samples of young adults (n = 23) were collected between 08.

Protective effect of bromelain on corrosive burn in rats.

Introduction: In some cases, the tongue and oesophagus tissues are damaged by the corrosive burn. Surgical interventions may cause scar formation, and severe burns treatment methods are limited. This study aims to investigate bromelain, a phytotherapeutic product, on the corrosive burn as a non-surgical option and as an adjunctive therapy, insofar as the treatment of corrosive wounds is not limited only to the treatment of oxidative stress and inflammatory reactions.

The effectiveness of different ankle strengthening training programs on performance.

Background: The purpose of this study was to investigate the effectiveness of different ankle strengthening training programs: eccentric, concentric, and resistance bands, on performance of university level sedentary males.

Methods: Sixty-three males between the ages of 18 and 26 years were randomized to either eccentric isokinetic (N.=21), concentric isokinetic (N.

Genetic-fuzzy logic model for a non-invasive measurement of a stroke volume.

Background: Despite the importance of stroke volume readings in understanding the work of the cardiovascular system in patients, its routine daily measurement outside of a hospital in the absence of special equipment presents a problem for a comprehensive assessment of the heart performance.

Objective: The purpose of this study was to develop a new non-invasive technique for measuring a stroke volume based on the relationship between time skin warming and a blood flow.

Methods: .

Comparison of surface roughness and color stainability of 3-dimensionally printed interim prosthodontic material with conventionally fabricated and CAD-CAM milled materials.

Statement Of Problem: Studies on the surface roughness and color stainability of interim prostheses produced with 3-dimensional-printing technology are lacking.

Purpose: The purpose of this in vitro study was to investigate the effect of different surface treatments on the surface roughness and stainability of 3-dimensionally printed, computer-aided design and computer-aided manufacturing (CAD-CAM) milled and conventional interim materials.

Material And Methods: A total of 320 specimens were fabricated from autopolymerizing polymethyl methacrylate, bis-acryl composite resin, CAD-CAM polymethyl methacrylate resin (milled), and 3-dimensionally printed composite resin (printed) (n=80).

Distribution of adhesive layer in class II composite resin restorations before/after interproximal matrix application.

Objectives: This study aimed to morphologically investigate the distribution of the adhesive layer when placed prior, or subsequent, to matrix positioning in direct-bonded Class II RBC restorations. Additional aim was to evaluate possible differences when using two-steps (CSE, Clearfil SE Bond2) or one-step adhesive system (CU, Clearfil Universal Bond Quick).

Methods: Standardized mesio-occlusal and disto-occlusal cavities were prepared on 20 human molars.

Primary diffuse large B-cell lymphoma of the mandible: A case report.

Introduction: Lymphomas are a heterogeneous group of malignant neoplasms of lymphocytes and their precursor cells. Lymphoma is seen 3.5% of all intraoral malignancies and is the second most common neoplasm after the squamous cell carcinoma in the head and neck region.

Cone-beam computed tomography imaging of dentoalveolar and mandibular fractures.

Three-dimensional imaging methods have an important role in the diagnosis of dentomaxillofacial fractures that can not be seen on the plain films. Cone-beam computed tomography (CBCT) is one of the three-dimensional imaging methods and has facilitated dental professionals' access to cross-sectional imaging. CBCT units allow different technical parameters and the data acquired by CBCT, can be reformatted.

Lingual Treatment of an Adult Patient with a Simplified Extraction Protocol.

Successful orthodontic treatment of adult cases depends on the biological, mechanical, and esthetic requirements of patients. While customized lingual appliance systems meet the esthetic expectations of the patients, they provide improved patient comfort, have three-dimensional mechanical control, and can be used for the treatment of all types of malocclusions. This report demonstrated the use of fully customized lingual orthodontic brackets for treating an adult case with extraction.
