Treatment Outcomes And Retention In Medicaid And Non-Medicaid Orthodontic Patients, Ashkan Ghaffari Jan 2008

Treatment Outcomes And Retention In Medicaid And Non-Medicaid Orthodontic Patients, Ashkan Ghaffari

Theses and Dissertations

Medicaid orthodontic patients have been shown to miss more appointments and break more appliances than self-pay patients, indicating a greater tendency toward non-compliance. Lack of compliance during the post-treatment phase can be detrimental to retention. The purpose of this study was to determine whether there is a difference in PAR score changes between Medicaid and non-Medicaid patients during and after orthodontic treatment. PAR scores were determined using study models of 43 Medicaid and 39 non-Medicaid patients before and at the end of active treatment, and 24 Medicaid and 42 non-Medicaid patients at the end of treatment and at an average …


Alternative Orthodontic Bonding Protocol Using Self Etching Primer, Rush-Baker Gaines Caldwell Jan 2008

Alternative Orthodontic Bonding Protocol Using Self Etching Primer, Rush-Baker Gaines Caldwell

Theses and Dissertations

The purpose of the current study was to develop a bonding method that can achieve clinically acceptable bond strength values while leaving a minimum amount of adhesive on the tooth surface during the debonding process. One hundred teeth were randomly assigned into groups. Five different enamel surface preparation protocols were tested (N = 20, each): Conventional acid etch, standard SEP, SEP applied with a light brush stroke (altered SEP 1), SEP applied directly to the composite of pre-coated bracket (altered SEP 2), and Primer Only groups. Brackets were debonded using an Instron universal testing machine (Instron, Canton, MA) in shear …


The Psychosocial Influence Of Dental Esthetics In Adolescents As Judged By Peers, Scott Thomas Henson Jan 2008

The Psychosocial Influence Of Dental Esthetics In Adolescents As Judged By Peers, Scott Thomas Henson

Theses and Dissertations

The purpose of this study was to determine if dental esthetics affects the perception of adolescents regarding their peer's social aptitude in specific areas such as athletics, popularity, leadership, and academics. Ten patient photographs (4 males, 6 females) from a private orthodontic practice in Richmond, VA were selected for inclusion in this study. The frontal smiling photographs were digitally modified with insertion of either an ideal smile (straight) or a non-ideal smile (crooked) to create an image identical to the original except for an altered dental complex. Laypersons rated the straight and crooked patient photographs for athletic performance, socialization skills …


Orthodontic Bracket Bond Strength Using Self-Etching Primer With Or Without Pumice Or Acid Etch Pretreatment, Ana Paula Decastro Jan 2008

Orthodontic Bracket Bond Strength Using Self-Etching Primer With Or Without Pumice Or Acid Etch Pretreatment, Ana Paula Decastro

Theses and Dissertations

The purpose of this study was to compare the shear bond strength of orthodontic brackets to enamel in four bonding protocols: SEP without prior pumicing (None), Pre-etch and SEP without prior pumicing (Pre-etch), control: SEP with prior pumicing (Pumice), and Pre-etch and SEP with prior pumicing (Both). 80 extracted bovine incisors were randomly divided into 4 groups of 20, and brackets were bonded under the different experimental conditions. Debonding force was measured with an Instron universal testing machine. A two-way ANOVA comparing the four groups indicated that there was a significant difference in debonding force (P = 0.001). The SEP …
