This study sought to investigate the effects of acetic NaF solutions on titanium and Ti alloy brackets. To this end, two different brackets were immersed in various NaF-containing solutions for three days. The Equilibrium Ti (EQ) bracket was composed of Ti only, whereas the Ortho 2 (OR) bracket was composed of Ti (base) and Ti-6A1-4V (wings). Brackets that(More)
PURPOSE To test the bonding of orthodontic brackets to teeth using a diode-pumped solid state (DPSS) laser. METHODS A total of 60 extracted human teeth were divided randomly into four groups: Group 1 (control)--he brackets were bonded to teeth using the quartz-tungsten-halogen (QTH) light (800 mW/cm2) for 40 seconds; Groups 2-4--the brackets were bonded(More)
We evaluated 3-dimensional changes in the temporomandibular joints of children with skeletal Class III malocclusion and maxillary deficiency after facemask therapy for maxillary protraction. Eighteen children with anterior crossbite and a Class III molar relationship underwent facemask therapy for maxillary protraction, after which they exhibited positive(More)
The purpose of this work to evaluate quantitatively ventricular alterations of hydrocephalic Maltese dogs using low-tesla MRI. The height, area, and volume of the ventricles and brain were measured in 40 Maltese (20 normal and 21 hydrocephalic dogs) on MR images (at 0.2T MRI). All of the relative ventricle sizes were defined as the percent size of the(More)
