The aim of this study was to evaluate soft tissue differences between Turkish and North American adults by comparing two sample populations with ideal occlusion and well-balanced faces. Lateral cephalometric radiographs of 117 Anatolian Turkish adults (65 female and 52 male, mean age: 23.9 ± 2.8 years) were compared with a sample of 116 adults of European–American ancestry (64 female and 52 male, mean age: 25.0 ± 6.8 years). The cephalometric analyses of Holdaway, Epker, and Legan and Burstone were performed using Dolphin Image Software 9.0. Thirty-two measurements (27 linear and 5 angular) we ...Daha fazlası
Bu çalışmada, Multipl Skleroz tanısı için en kesin kriter olan bilgisayarlı beyin tomografisi bul-gulara incelenmiş ve klinik olarak multipl skleroz olduğu belirlenen hastalarımizen tomografi sonuçları, literatür bilgileriyle taritşılmiştır. Sonuçta, bilgisayarlı beyin tomografisi bulgulartnın, hastalık dönemlerine göre değişebileceği ve diğer bazı nörolojik hastalıklarla karıştırılabileceği kanısına varılmıştır. In this study, Cornputerized Tomographic findings that are the most definitive diagnostic criteria for rnultiple sclerosis have been evaluated. Computerized tornographic findings were ...Daha fazlası
Tamamen sağır olan 5 denekte okuma sırasında göz anneleri elektrookülografik olarak kaydedildi. Elektrookülografik paternlerin büyük sakkadlar ve uzun süreli fiksasyonlar göstermesi dikkat çekiciydi. Beklendiği gibi sağır-dilsizler fonolojik olmayan okuma süreci ile okunmuş kabul edildi. Yine de sonuçlar daha fazla kantitatif çalışma için motive oldu. Eye movernents during reading in 5 completely deaf-mute subjects were electrooculographically recorded. It was notable that electrooculographical patterns showed large saccads and fixations with long duration. As expected the deaf-mutes were cons ...Daha fazlası

Bu çalışmada, en az bir yıldır major antiepileptik ilaç kullanan 42 epileptik hastada tiroid hormonları, testosteron, gonadotropin ve prolaktin değerleri ölçülerek ortaya çıkan değişiklikler araştırıldı. Sonuçta major antiepilepukleriın özellikle serbest T4 ve total testosteron değerlerinde azalma yaptığı belirlendi.
In this work, 42 epileptic patients who were using major antiepileptic drugs more than a year, were chosen for the changes in their thyroid, testosterone, gonadotrophins, and prolactin hormone levels. Continuous use of antiepileptic drugs had a specific and statistically significa ...Daha fazlası
1984-1990 yılları arasinda S.U. Tap Fakültesi Göğüs ve. Kalp Damar Cerrahisi Anabilim Dalında tetkik ve tedavi ettiğimiz 20 mediastinal kitleli hasta değerlendirildi. Erken teşhis ve tedavi ile, ma-lign tümörlü hastalarda daha uygun prognoza sahip olunabileceği kanaatine ulaşıldı. The cases of twenty patients, treated for turnors and cysts of mediastinurn between 1984-1990, have been investigated. it has been established that a more favourable prognosis could be obtained through early diagnosis and treatrnent of the patients with malignant turnors.
INTRODUCTION:
The aim of this study was to test the null hypothesis that increased irregularity of the mandibular incisors is associated with a reduction in the alveolar support on cone-beam computed tomographic sections.
METHODS:
From a sample of 1100 digital volumetric tomographs, 125 tomographs of subjects with Class I malocclusion (mean age, 21.6 ± 4.8 years) were selected for this study. An irregularity index was used to categorize these tomographs as having mild, moderate, or severe crowding. All tomographs were taken by using an iCAT (Imaging Sciences International, Hatfield, Pa) ima ...Daha fazlası
Objective: To evaluate the changes in cortical bone thickness, alveolar bone
height, and the incidence of dehiscence and fenestration in the surrounding
alveolar bone of posterior teeth after rapid maxillary expansion (RME) treatment
using cone-beam computed tomography (CBCT). Methods: The CBCT records of
20 subjects (9 boys, mean age: 13.97 ± 1.17 years; 11 girls, mean age: 13.53 ±
2.12 year) that underwent RME were selected from the archives. CBCT scans had
been taken before (T1) and after (T2) the RME. Moreover, 10 of the subjects had
6-month retention (T3) records. We used th ...Daha fazlası
Objective: To evaluate the root resorption after rapid maxillary expansion (RME) via cone-beam
computed tomography (CBCT).
Materials and Methods: Records of 25 patients who had undergone RME with tooth-borne
banded expander were obtained from the archive of the orthodontic department. CBCT data were
reconstructed with surface and volume rendering, and the volumetric images were manipulated to
display the root surfaces from various orientations. On these three-dimensional images, permanent
first molars and first and second premolars were segmented, and their roots were isolated.

Objective: To evaluate lower incisor position and bony support between
patients with Class II average- and high-angle malocclusions and compare
with the patients presenting Class I malocclusions. Methods: CBCT records of
79 patients were divided into 2 groups according to sagittal jaw relationships:
Class I and II. Each group was further divided into average- and high-angle
subgroups. Six angular and 6 linear measurements were performed. Independent
samples t-test, Kruskal–Wallis, and Dunn post-hoc tests were performed for
statistical comparisons. Results: Labial alveolar bone th ...Daha fazlası
Objective: To evaluate and compare the effects of enamel microabrasion, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and their combination on the shear bond strength (SBS) of orthodontic brackets bonded to demineralized enamel surface.
Materials and Methods: One hundred human first premolar teeth were randomly allocated to one of five groups. Group I was considered as the control of other groups. For the remaining groups, demineralization was performed via solutions. In group II, brackets were directly bonded to the demineralized enamel surface. CPP-ACP was applied in group ...Daha fazlası
Objective
We evaluated the detachment force, amount of deformation, fracture mode, and pull-out force of 3 different wires used for bonded lingual retainer fabrication.
Methods
We tested 0.0215-inch five-stranded wire (PentaOne, Masel; group I), 0.016 × 0.022-inch dead-soft eight-braided wire (Bond-A-Braid, Reliance; group II), and 0.0195-inch dead-soft coaxial wire (Respond, Ormco; group III). To test detachment force, deformation, and fracture mode, we embedded 94 lower incisor teeth in acrylic blocks in pairs. Retainer wires were bonded to the teeth and vertically directed force was ap ...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
