An Analysis Of Adhesion Promoters On Shear Bond Strength Of Orthodontic Brackets To Teeth, Loren Andrew Cadelinia
An Analysis Of Adhesion Promoters On Shear Bond Strength Of Orthodontic Brackets To Teeth, Loren Andrew Cadelinia
UNLV Theses, Dissertations, Professional Papers, and Capstones
Purpose:The aim of this study was to evaluate the shear bond strength of two adhesion promoters, EnhancetmLC and AssureRUniversal Bonding Resin, and their effects with two different adhesion systems (Light Bondtmand TransbondtmXT). To better understand their behavior upon failure, the amount of adhesive remnant remaining on the tooth surface was also observed.
Methods:One-hundred forty human premolars, which were extracted for reasons other than this study, were utilized and divided into seven groups of 20 teeth each. Groups A1 and B1 were bonded without adhesion promoters and with two different adhesive systems - Light Bondtmand TransbondtmXT. Groups A2 and B2 were …
Frictional Forces Of A Fixed, Esthetic Orthodontic Appliance System, Brady Michael Nance
Frictional Forces Of A Fixed, Esthetic Orthodontic Appliance System, Brady Michael Nance
UNLV Theses, Dissertations, Professional Papers, and Capstones
Purpose: The demands of an all esthetic fixed orthodontic appliance system are ever increasing in today's world. Frictional values of an esthetic, fixed orthodontic appliance system are needed to evaluate their clinical effectiveness for orthodontic treatment. The aim of this study is to evaluate the frictional values of various esthetic orthodontic archwires ligated to an esthetic orthodontic bracket.
Methods: Three types of stainless steel and nickel titanium alloy (niti) esthetic orthodontic archwires (epoxy, poly, plastic) in four sizes (.016, .018, .017 x .025, .019 x .025 inches) were ligated to both a stainless steel bracket system and a ceramic (esthetic) …
Effect Of Gingival Margin Design On Retention Of Thermoformed Orthodontic Aligners, Daniel P. Cowley
Effect Of Gingival Margin Design On Retention Of Thermoformed Orthodontic Aligners, Daniel P. Cowley
UNLV Theses, Dissertations, Professional Papers, and Capstones
Purpose: The aim of this study was evaluate the effect of gingival margin design (scalloped vs. straight cut at gingival zenith vs. straight cut 2mm above gingival zenith) on the retention of thermoformed aligners. Retention of aligners is a critical requirement for efficient tooth movement.
Methods: Two thermoform aligner materials were used, Invisacryl A and Invisacryl C, in 0.040 mil (1mm) thickness. Six aligner designs were fabricated for each of the two aligner materials (12 total aligner designs). Aligner designs are scalloped, straight cut at gingival zenith (0mm), and straight cut 2mm above gingival zenith on a model with attachments. …
Retrospective Evaluation Of Oral Health Services For Underserved Children In Clark County, Nevada, Earl Taylor Spader
Retrospective Evaluation Of Oral Health Services For Underserved Children In Clark County, Nevada, Earl Taylor Spader
UNLV Theses, Dissertations, Professional Papers, and Capstones
Disparities in utilization of oral health services have been shown to exist through epidemiological investigations and data analysis. Specifically, disparities exist for utilization of preventative dental care (PDC) and unmet dental need (UDN). The disparities in utilization of PDC and UDN are associated with demographic and insurance variables.
To address the oral health disparities, the University of Nevada, Las Vegas-School of Dental Medicine (UNLV-SDM) was created to improve the health of the citizens of Nevada through innovative programs of oral healthcare services to the community. More recently, UNLV-SDM opened a pediatric dental residency training program to provide care directly to …
