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
Introduction: The aim of this study was to evaluate the prevalence of bacteremia associated with an orthodontic
stripping procedure. Methods: The study included 29 orthodontic patients (mean age, 18.2 6 3.4 years). We
used a standardized stripping procedure: a perforated stripping disk with a contra-angle hand piece was used
at a low speed (\15,000 rpm; 10 seconds) on the mandibular anterior teeth. Blood samples were collected
by inserting a cannula into the left antecubital fossa. A baseline sample was taken before treatment, and
a second sample was taken after the stripping procedure. T ...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
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
The aim of this follow-up study was to evaluate the effects of Pre-Orthodontic Trainer (POT) appliance on the anterior temporal, mental, orbicularis oris, and masseter muscles through electromyography (EMG) evaluations in subjects with Class II division 1 malocclusion and incompetent lips. Twenty patients (mean age: 9.8 ± 2.2 years) with a Class II division 1 malocclusion were treated with POT (Myofunctional Research Co., Queensland, Australia). A group of 15 subjects (mean age: 9.2 ± 0.9 years) with untreated Class II division 1 malocclusions was used as a control. EMG recordings of treatment ...Daha fazlası
