Introduction: The aim of this prospective clinical trial was to assess the effects of varying force directions on the
dynamic measurement of natural head position and orofacial airway dimensions of Class III patients during maxillary
orthopedic protraction compared with an untreated control group. Methods: The conventional facemask
group comprised 15 patients (8 girls, 7 boys; mean age, 9.6 6 1.3 years), the modified facemask group comprised
15 patients (7 girls, 8 boys; mean age, 9.5 6 1.5 years), and the control group comprised 15 subjects
(7 girls, 8 boys; mean age, 9.8 6 1.6 years). N ...Daha fazlası
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
The aim of this study was to investigate the efficiency of different diagnostic methods in detection of residual dentinal caries
in excavated cavities. Fifty extracted molar with deep dentinal carious lesions were excavated using a slow-speed handpiece.
All cavities were assessed by laser fluorescence(LF) device, electronic caries monitor(ECM), and caries detector dye(CDD) by
three independent observers blindly. The measurements were repeated after two weeks. Specimens containing dentin slices
150 μm in thickness were prepared for histological analyses. The existence and absence of car ...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
This study was performed to determine the concentrations
of some trace metals (Cd, Cu, Pb, Ni, Zn, and Fe) in
Holothuria tubuosa (Gmelin, 1788) belonging to Echinoderm
species and in sediments that they live at three different stations
(Gelibolu, Umur Bey/Lapseki, and Dardanos) on
Dardanelles Strait between April 2013 and March 2014. The
mean trace metal concentrations determined in H. tubulosa
and sediment were as follows: Cd 0.18 mg/kg, Cu 2.43 mg/
kg, Pb 2.09 mg/kg, Ni 14.58 mg/kg, Zn 16.86 mg/kg, and Fe
73.46 mg/kg and Cd 0.70 mg/kg, Cu 5.03 mg/kg, Pb
14.57 mg/kg, Ni 27.15 mg/kg, ...Daha fazlası
Objective: This study was conducted to examine the effect of preoperative introductory training, to be performed for patients who would undergo an operation for gynecological surgery, on anxiety level. Material and Method: This study designed as a randomized controlled trial. It constituted the research population 60 patients, who would undergo an operation for gynecological surgery for the first time. All patients were visited by the researcher in the clinic environment the day/night before the surgery, information was given about the study, the questionnaire and State-Trait Anxiety Scale wer ...Daha fazlası
Age-related macular degeneraton is an eye disease that is one of the biggest causes of blindness worldwide. Age-related macular degeneration is a complex and multifactorial disease. Although there are many risk factors both environmental and genetic such as ethnicity, age, genetics, family history, and oxidativestress, the most effective and modifiable risk factor in preventing age-related macular degeneration is smoking. In addition, the fact that nutrition is a potentially modifiable risk factor suggeststhat it may reduce the risk of age-related macular degeneration. In many epidemiological ...Daha fazlası
ABSTRACT
Objective: Dermatological diseases are public health problems. Several factors including subjective diagnosis, lack of enough dermatologists, inability to go to a dermatologist due to old age, psychological problems or pandemic like coronavirus enforce to use automated techniques in dermatology. In the literature, there are many techniques on automated lesion classification to provide accurate, objective, reliable and reproducible results for the diagnosis of several dermatological diseases. However, although the techniques are promising, they become useless without a user interface ...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.
