Acetaminophen Versus Ibuprofen for the Control of Immediate and Delayed Pain Following Orthodontic Separator Placement
(University of Missouri--Kansas City, 2010)The purpose of this investigation was to compare pain control effectiveness of preemptive and postoperative acetaminophen, ibuprofen, and placebo following orthodontic separator placement. Subjects were randomly assigned ... -
The effect of archwire vibrations on the stick-slip behavior of the bracket-archwire interface utilizing clinically relevant tipping moments
(University of Missouri--Kansas City, 2011-07-27)This study evaluated bracket-archwire frictional resistance as a function of ligation method and archwire vibration. In vivo archwire vibrations were measured to obtain frequencies and amplitudes for ex vivo testing. ... -
Effect of refrigerant spray on orthodontic composite resin-bracket debond strength and associated adhesive remnant index
(University of Missouri--Kansas City, 2012)This study evaluated effects of refrigerant spray and crosshead speed on orthodontic composite resin shear debond strength and Adhesive Remnant Index (ARI) after bond failure. Orthodontic brackets were bonded to forty ... -
The effect of simulated oral and clinical conditions on the fracture strength of ceramic bracket tie-wings
(University of Missouri--Kansas City, 2011-08-12)This study examined the effect of simulated oral and clinical conditions on the tie-wing fracture strength of a polycrystalline and a monocrystalline bracket. Fracture strength was measured for brackets as-received ... -
Effects of topical fluoride prophylactic agents on the mechanical properties of orthodontic nickel-titanium closed coil springs
(University of Missouri--Kansas City, 2012)This study evaluated topical fluoride effects on mechanical properties of nickel-titanium orthodontic closed coil springs. Unloading force and rigidity were measured at 1, 4, 8, and 12 weeks, after springs were exposed to ... -
Isopropyl alcohol to counteract effects of freezing on extended-storage alginates
(University of Missouri--Kansas City, 2011-07-08)The purpose of the study was to evaluate the effects of freezing and isopropyl alcohol (IA) on two extended-storage alginates. Impressions were made of a custom stainless steel model of known dimensions and stored for ... -
Jaw mechanics and muscle behavior in adolescents with different craniofacial morphologies
(University of Missouri--Kansas City, 2012)Jaw mechanics and muscle behavior were evaluated in ten dolichofacial versus ten brachyfacial adolescents. Subjects consented to participate. Numerical modeling predicted TMJ loads for molar biting angles based on minimization ... -
Quality and intensity of pain associated with continuously applied orthodontic stresses of relatively high and low magnitudes
(University of Missouri--Kansas City, 2011-07-21)The purpose was to assess longitudinally pain intensity and quality during tooth translation by 2 continuous stresses. Eight subjects (five males, 3 females) who required maxillary first premolar extractions had maxillary ... -
Synthesis and analysis of siloranes for use as a biomaterial and extended twisted molecular ribbons
(2013)The development of complex organic molecules with industrial potential requires meticulous synthetic methodologies coupled with detailed investigations surrounding their physical properties. This dissertation encompasses ...
