Voluntary teeth clenching during exercise in a natural environment: prevalence and gender differences
(2013)
Background/Objectives: Voluntary teeth clenching (VTC) has been researched with respect to performance enhancement, but little evidence has verified its prevalence. This study's objective was to determine if VTC occurred ...
Orthodontic bracket bond strength and resin composite adhesive degree of conversion associated with type of curing unit and total energy
(2013)
This study examined the effect of light curing sources on shear bond strength and degree of conversion of orthodontic resin composite adhesive as function of type of curing unit and total energy, as well as evaluated the ...
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 ...
A pilot study evaluating the effect of collagen sponges on healing and pain following tooth extraction
(2013)
Background: Clinicians often use collagen-derived matrices to aid in the regeneration of periodontal tissue during periodontal therapy; other uses of these materials include clot stabilization, wound protection, and patient ...
Evaluating the quality and efficacy of care provided by extended care permit dental hygienists in a school based dental home
(2013)
Lack of access to oral health care is a growing problem for low income children in the United States. One proposed solution to this problem is utilizing dental hygienists to the full extent of their education and training. ...
Modeling the soft tissues of the knee joint
(2013)
Computational modeling of the knee helps us better understand the forces and strains placed on knee structures, such as the ligaments and cartilage, during ambulatory activities. With better understanding of ligament strains ...
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. ...
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 ...
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 ...
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 ...
A qualitative study of the Extended Care Permit dental hygienists in Kansas
(University of Missouri--Kansas City, 2011-08-01)
Currently, thirty-two states allow some type of alternative practice settings for dental hygienists. This qualitative study was designed to explore the experiences of the Extended Care Permit (ECP) dental hygienist in the ...
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 ...
Characterization of the Organic Matrix of Mature Human Tooth Enamel: Structure, Macromolecular Composition and Effect of Radiotherapy
(2014-09-30)
Mature human tooth enamel contains a small amount of organic matrix locally concentrated within its innermost region, which is tougher and more crack resistant than the outer bulk phase. Although the enamel organic matrix ...
Jaw mechanics and muscle behavior in adolescents with different craniofacial morphologies
