The human body consists of different systems which include the nervous system, the cardiovascular system, the musculoskeletal system, etc. Each system performs some kind of vital task and carries on many physiological processes. For example, the primary functions of the musculoskeletal system can be summarized as generating forces, producing motion, moving substance within the body, providing stabilization, and generating heat. Physiological processes are multifaceted fact and most of them manifest themselves as signals that reflect their nature and activities. These types of signals may be ho ...Daha fazlası
Objective: To test the hypotheses that (1) there is no difference in mandibular asymmetry between
the crossbite and normal side in a unilateral crossbite group (UCG) and between the right and left
sides in a bilateral crossbite group (BCG) and a control group (CG); and (2) there is no significant
difference in mandibular asymmetry among crossbite groups and control group.
Materials and Methods: The cone-beam computed tomography scans of three groups were
studied: (1) 15 patients (6 male, 9 female; mean age: 13.51 6 2.03 years) with unilateral posterior
crossbite; (2) 15 patients (8 male, ...Daha fazlası
Objective: To identify the effect of rapid maxillary expansion (RME) procedure on dynamic
measurement of natural head position (NHP).
Materials and Methods: The treatment group comprised 23 patients, 12 girls and 11 boys (mean
age: 10.1 6 1.1 years), and the control group comprised 15 subjects, 8 girls and 7 boys (mean age:
9.7 6 1.4 years). The test subjects underwent RME treatment using full cap acrylic device, and the
mean amount of expansion was 5.48 mm. An inclinometer and a portable data logger were used to
collect the NHP data. Intragroup changes were evaluated by using nonparamet ...Daha fazlası
Objective: This study aimed at evaluating the changes in mandibular arch widths and buccolingual inclinations of mandibular posterior teeth after rapid maxillary expansion (RME). Methods: Baseline and post expansion cone-beam computed tomographic (CBCT) images of patients who initially had bilateral posterior cross-bite and underwent RME with a banded type expander were assessed in this study. The patients included 9 boys (mean age: 13.97 1.17 years) and 11 girls (mean age: 13.53 2.12 years). Images obtained 6 months after retention were available for 10 of these patients. Eighteen angular and ...Daha fazlası
Objective: To determine whether there is any difference between the cleft and non-cleft sides of the mandible
in unilateral cleft lip and palate (UCLP) patients, or the right and left sides in control patients; and
to determine if there is any difference between the mandibular asymmetry of UCLP patients and that of
control patients. Methods: We examined cone-beam computed tomography (CBCT) scans of 15 patients
with UCLP and 15 age- and gender-matched control patients. We evaluated 8 linear, 3 surface, and 3 volumetric
measurements and compared the cleft/non-cleft sides of UCLP patients an ...Daha fazlası
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
Objective –The aim of this study was to evaluate the effects of local resveratrol
(RSVL) administration on bone formation in response to expansion of the interpremaxillary
suture, in rats.
Material and Methods – Twenty 50- to 60-day-old male Wistar rats were separated
into two equal groups. Both groups were subjected to expansion, and 30 cN of force
was applied to the maxillary incisors with helical-spring. Twenty-four hours after
appliance placement, single-dose 10 lmol ⁄ kg RSVL in the dimethylsulfoxide
(DMSO) was injected to the inter-premaxillary suture in the experimental group. In ...Daha fazlası
To evaluate the shear bond strength (SBS), fracture mode, wire pull out (WPO) resistance and microleakage between low-shrinking and conventional composites used as a lingual retainer adhesive. Methods: A total of 120 human mandibular incisor teeth, extracted for periodontal reasons, were collected. Sixty of them were separated into two groups. To determine the SBS, either Transbond-LR (3M-Unitek) or Silorane (3M-Espe) was applied to the lingual surface of the teeth by packing the material into standard cylindrical plastic matrices (Ultradent) to simulate the lingual retainer bonding area. To t ...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
Çocuk ve adolesanlarda konjenital olarak eksik veya travma nedeni ile kaybedilmiş daimi kesici dişlerden kaynaklanan problemlerin tedavisi için farklı yaklaşımlar mevcuttur.

Thanks to official duties Evliya Çelebi went to Iran twice in 1646-1647 and in
1655. First time he was sent as an envoy by Defterdarzade Mehmed Pasa to Kalb
Ali Khan, the governor of Tabriz. During his duty Evliya Çelebi traveled around
the north of the Safavid territories (Azerbaijan, Shirvan, Daghestan and Georgia)
and returned to Erzurum. In this study initially the route of his journey is
discussed. Then, information given by him about history and physical conditions
of the castles on his route were evaluated.
