Resonance frequency analysis of orthodontic miniscrews subjected to light-emitting diode photobiomodulation therapy

TANCAN UYSAL

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

As we entered 2020, many countries were already facing a nursing shortage. The World Health Organization’s first State of the World’s Nursing report, launched in April this year, reported a g ...Daha fazlası

Heavy Metal Accummulation in Muscles and Total Bodies of Mullus barbatus, Trachurus trachurus and Engraulis encrasicolus Captured from the Coast of Sinop, Black Sea

SANİYE TÜRK ÇULHA | MEHMET ÇULHA

The levels of heavy metals viz., Cd, Cu, Fe, Ni, Pb, Zn and Al were determined by ICP-AES in the muscles and total bodies of Mullus barbatus (Linnaeus 1758), Trachurus trachurus (Linnaeus 1758), Engraulis encrasicolus (Linnaeus 1758) captured from the coast of Sinop. The order of the levels of the heavy metals in the total fish samples was Fe > Zn > Al > Pb > Cu > Ni > Cd, whereas in the muscles, the order was Zn > Fe > Cu > Al > Pb > Ni > Cd. The experiment results are discussed by comparison with literature values.

Influence of Pre-Orthodontic Trainer treatment on the perioral and masticatory muscles in patients with Class II division 1 malocclusion

TANCAN UYSAL |

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
