Accumulating data have shown that the level of serum homocysteine in patients with mild cognitive impairment, vascular dementia and Alzheimer’s disease is higher than normal while the underlying mechanism is not fully understood. Here, a hyperhomocysteinemic rat model was made by maintaining rats on a diet high in methionine. The cognitive behavior, level(More)
PURPOSE To analyze the differences of root resorption between passive self-ligating and conventional brackets, and to determine the relationship between passive self-ligating brackets and root resorption. METHODS Fifty patients were randomly divided into 2 groups using passive self-ligating brackets or conventional straight wire brackets (0.022 system),(More)
OBJECTIVE To create an integrated digital maxillodental model and to apply it in computer aided design (CAD) of individualized lingual brackets in order to align both crowns and roots without fenestration and dehiscence. METHODS Cone-beam computerized tomography (CBCT)-based maxillodental model and laser-scanned dental model were integrated by auto(More)
OBJECTIVE To investigate the bond strengths of customized titanium bracket manufactured by selective laser melting. METHODS Eighty human premolars which had been extracted for orthodontic purpose were collected and divided randomly (by random table) into two groups (customized bracket group and 3M bracket group, 40 molars in each group). The 35%(More)
OBJECTIVE To assess the accuracy of anterior tooth movement using clear aligners in integrated three-dimensional digital models. METHODS Cone-beam computed tomography was performed before and after treatment with clear aligners in 32 patients. Plaster casts were laser-scanned for virtual setup and aligner fabrication. Differences in predicted and achieved(More)
The aim of this study is to explore the effects of abnormal occlusion and functional recovery caused by functional mandible deviation on the head and neck muscles and muscle spindle sensory-motor system by electrophysiological response and endogenous monoamine neurotransmitters' distribution in the nucleus of the spinal tract. Seven-week-old male Wistar(More)
