Objectives: The aims of the present study were (1) to determine ethnic differences in craniofacial
dimensions between Turkish and Saudi populations and (2) to identify possible gender differences
between males and females, based on a sample of untreated young adult subjects with
normal occlusions and well-balanced faces.
Methods: In total, 163 cephalometric radiographs were traced and evaluated to compare
untreated adults of Turkish and Saudi ethnicity. The Turkish group comprised 86 subjects; 45
females and 41 males. The Saudi group comprised 77 subjects; 39 females and 38 males. For st ...Daha fazlası
Horizontal root fractures are rare in comparison to other types of injuries and the reported
prevalence in the literature is between 0.5% and 7%. The treatment and prognosis of root
fractures depend on many variables, the most important being the length of time between trauma
and treatment, degree of dislocation and mobility, site of fracture, fixation period, stage of root
development, age of patient, and quality of treatment. The ideal healing type is hard tissue healing.
The aim of these case reports is to present four different patients who had horizontal root fractures
of imma ...Daha fazlası
This in vitro study was to evaluate the erosive potential of four soft drinks at different times on bovine teeth by profilometry. Bovine incisors buccal side was sectioned with a diamond saw and a total of 100 enamel blocks were prepared (8 × 4 × 0.5 mm). Five specimens each were exposed to 60 ml of soft drinks (Sprite, Coca Cola, Cappy-orange and Ayran) for 15, 30, 60, 120 and 180 minutes in a continuously vibrating soft drinks bath in a beaker at room temperature. Surface loss of the specimens was determined with a profilometry. The data were analyzed by two-way analysis of variance and Tuke ...Daha fazlası
Coiling of the artery is a rare morphologic entity most frequently described in the internal carotid artery. Herein we present two cases with symptomatic kinked internal carotid artery: one suffering from paresthesia of the right arm and speech disturbances and the other suffering from weakness of the left half of the body and speech disturbances. Both patients were treated surgically. None of the patients experienced any peri- or postoperative complications.
Global crises are increasing day by day due to the rapid depletion of energy supplies around the planet. One of the goals of engineering is to prevent this situation by developing innovative solutions to this rapid energy consumption that has disappeared in the world. A solution could be to reduce the energy consumption of the machines that are used during production. In this study, a new design technique based on the neuro-regression approach and non-linear regression modeling was offered as an alternative to Taguchi design to reduce energy consumption. Thus, a cutting parameter optimization ...Daha fazlası
This study investigates the optimum weld area on a popular aerospace alloy (i.e., Inconel 825) made by the electron beam welding technique. Welding speed (S), beam current (I), accelerating voltage (V), and beam oscillation (O) are considered as process parameters to study the weld bead area (WA) of the weldments. An instructive study on multiple non-linear neural regression analyses has been done as a basic introduction to neuro regression modeling with artificial neural network (ANN) philosophy. To do this, the experimental prediction has been modeled with 14 predictive functional structures ...Daha fazlası
Abstract In this study, machine learning-based models have been used to estimate the return loss parameters of the operational resonant frequency of the U-slotted UHF RFID antenna. The data set utilized, consisting of 544 instances, has been collected from the simulation software as a consequence of the parametric evaluation of the antenna design parameters. Distinct machine learning methods have been used on two different types of output data, complex and linear scattering parameters, and the models' prediction performance has been evaluated. In the single-output regression models, a mean-squ ...Daha fazlası
On 6th February 2023, two consecutive earthquakes occurred in our country with a magnitude of 7.8 Mw in Kahramanmaras (Pazarcik) and 7.6 Mw in Kahramanmaras (Elbistan). Due to these earthquakes and aftershocks, 48,448 people have lost their lives in Türkiye. A bi-directional and very intense population movement from/to the earthquake area after these earthquakes was observed. Knowing the residence decisions of the disaster victims is important. In the face of the “disaster of the century”, “potential or actual” disaster victims or “pseudo disaster victims”, who exhibit the behavior of disaster ...Daha fazlası
The aim of this experimental study was to evaluate
the effects of light-emitting diode-mediated-photobiomodulation
therapy (LPT), on the rate of orthodontic tooth movement (TM)
and orthodontically induced root resorption, in rats. Twentymale
12-week-oldWistar rats were separated into two groups (control
and LPT) and 50 cN of force was applied between maxillary left
molar and incisor with a coil spring. In the treatment group, LPT
was applied with an energy density of 20 mW/cm2 over a period
of 10 consecutive days directly over the movement of the first
molar teeth area. The distance b ...Daha fazlası
