Many studies in humans and rodents have shown that the anterior cingulate cortex (ACC) plays a critical role in the regulation of pain-related aversion and that the projection from the rostral ACC (rACC) to the ventral tegmental area (VTA) is implicated in this modulation process.The ACC is also reported to be involved in the regulation of itch-scr
OBJECTIVE: By means of a photoelastic model, this study analyzed the stress caused on conventional and self-ligating brackets with expanded arch wires.METHOD: Standard brackets were adhered to artificial teeth and a photoelastic model was prepared using the Interlandi 19/12 diagram as base.Successive activations were made with 0.014-in and 0.018-in
