The aim of this prospective experimental study was to evaluate the effect of light-emitting diode (LED) photobiomodulation therapy (LPT) on the stability of immediately loaded miniscrews under different force levels, as assessed by resonance frequency analysis (RFA). Sixty titanium orthodontic miniscrews with a length of 8 mm and a diameter of 1.4 mm were implanted into cortical bone by closed flap technique in each proximal tibia of 15 New Zealand white adult male rabbits (n = 30). The animals were randomly divided into irradiated and control groups under different force levels (0, 150, and 3 ...Daha fazlası
Background: The aim of this study is to determine the relationship between the educational status of the parents who applied to the pediatric dentistry clinic and their approach to children’s oral-den- tal health. Methods: Questionnaire form with 8 question was used for parents. 226 parents which were selected randomly were included to the study. All parents gave their verbal assent to participation and infor- mation about questionnaire was given to them. The data were ana- lyzed by using chi-square tests. Results: The mean age for the mothers was 34,9, for the fathers was 39, for their childr ...Daha fazlası
Introduction: The aims of this study were to evaluate the effect of an antibacterial monomer-containing selfetching
adhesive in reducing enamel demineralization around orthodontic brackets in vivo and to compare it
with the conventional adhesive system quantitatively. Methods: Fourteen orthodontic patients were randomly
divided into 2 equal groups; they received brackets fitted to all their teeth, bonded with either Clearfil Protect
Bond (Kuraray Medical, Okayama, Japan) (experimental group) or Transbond XT (3M Unitek, Monrovia, Calif)
(control group). Block randomization to obtain equal ...Daha fazlası
Objective: To study and compare the effects of different demineralizationinhibition
methods on the shear bond strength (SBS) and fracture mode of an
adhesive used to bond orthodontic brackets to demineralized enamel surfaces.
Methods: Eighty freshly extracted, human maxillary premolars were divided
into 4 equal groups and demineralized over the course of 21 days. Brackets were
bonded to the demineralized enamel of teeth in Group 1. In Group 2, bonding
was performed following resin infi ltration (ICON®, DMG, Hamburg, Germany).
Before bonding, pre-treatment with acidulated phosphate fluor ...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
Objective: To test the null hypothesis that the presence of alveolar defects (dehiscence and
fenestration) was not different among patients with different vertical growth patterns.
Materials and Methods: A total of 1872 teeth in 26 hyper-divergent (mean age: 24.4 6 4.8 years),
27 hypo-divergent (mean age: 25.1 6 4.5 years), and 25 normo-divergent (mean age: 23.6 6
4.1 years) patients with no previous orthodontic treatment were evaluated using cone-beam
computed tomography. Axial and cross-sectional views were evaluated with regard to whether
dehiscence and/or fenestration on buccal and l ...Daha fazlası
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
Ehlers Danlos Syndrome (EDS) is a connective tissue disease that has effect on the structure and function of collagen. Collagen is a fibrous protein that is one of the main building structures of connective tissues such as skin, tendon, bone and cartilage. Connective tissue requires all type of collagen to function correctly.
People with EDS may show symptoms such as skin hyperelasticity, joint hypermobility, increased tendency to bruise and abnormal scarring. Dental findings have been reported with some types of EDS. This case report describes the dental findings of a patient (10, c?) who ...Daha fazlası
Introduction: The aim of this study was to determine the peri-miniscrew implant crevicular fluid receptor
activator of nuclear factor-lB ligand (RANKL) and osteoprotegerin (OPG) levels around loaded and unloaded
miniscrew implants at different time intervals. Methods: Twenty loaded and 16 unloaded miniscrew implants
were included in this study. All miniscrew implants were placed bilaterally between the maxillary second premolars
and first molars as anchorage units for canine distalization. Peri-miniscrew implant crevicular fluid was taken
from the mesiobuccal aspects of the loaded and unl ...Daha fazlası
