Assessing Orthodontic-Bracket Impacts On Lip Profile At Bonding And Debonding Stages, Martin Trockel

Student Theses, Dissertations and Capstones

Introduction: One factor that contributes greatly to the lower face appearance and orthodontists have the ability to affect is lip profile. Clinical assessment of the lip profile is an important element in the decision of orthodontic treatment planning and in the evaluation of treatment progress and outcome. Three known factors influence the lip profile; the lip thickness, the underlying bone, and the tooth position. The positions and inclinations of the anterior teeth can affect the lip position, but it is unclear whether orthodontic brackets bonded to the labial surface of anterior teeth move the lip position and thereafter change the …

Effects Of Sodium Hypochlorite On Enamel Composition, Sonni Pellillo

Student Theses, Dissertations and Capstones

The purpose of this study was to evaluate the effects of sodium hypochlorite on the organic and inorganic composition of enamel. Background: With the advent of enamel bonding for orthodontic appliances in the late 1970s, it has been shown that traditional phosphoric acid etching affects the inorganic portion of the enamel.1, 2 In an attempt to enhance the acid etching pattern and, furthermore, the bond strength, additional pretreatment techniques that target the organic components of the enamel biofilm have been proposed. One such method is the non-invasive enamel pretreatment with 5.25% sodium hypochlorite (NaOCl) prior to phosphoric acid etching.3, 4 …

Strategies For Improving Patient Compliance, Diana V. Macri

Publications and Research

Patient compliance is the degree to which a person adheres to the professional advice healthcare providers offer. Aside from significantly compromising a person’s health, non-compliance also wastes resources and productivity. The monetary costs of medical noncompliance has been estimated to be around $300 billion a year. Demographic, disease severity and gender effects on compliance are small. In dental hygiene, where practitioners focus on the prevention of oral disease, motivating patients to practice healthy behaviors has long been a challenging, and often frustrating, aspect of practice. Any discussion of compliance must begin with a brief review of human development and the …

Access To Oral Health For Children On Mainecare In The Lakes Region Towns Of Bridgton, Casco, Sebago, And Naples, Carissa L. Parent

Muskie School Capstones and Dissertations

Although we know that children covered by Medicaid often do not receive needed dental services, the extent of the problem in Maine is not fully understood. In particular, rural communities in Maine may face challenges for families to access dental services for their children given low reimbursement rates and fewer available providers. This project addresses these gaps in knowledge by examining MaineCare- funded utilization and dental care access for children with MaineCare in four rural Maine towns in the Lakes Region.

Synthesis And Functional Evaluation Of Peptide Modified Poly (Lactic-Co-Glycolic Acid) Nanoparticles To Inhibit Porphyromonas Gingivalis Biofilm Formation., Paridhi Kalia

Electronic Theses and Dissertations

Periodontal disease is an oral inflammatory disorder that afflicts roughly 46% of the adults in the U.S. Currently, treatment of periodontal disease involves the removal of plaque from the gingival pocket (with possible antibiotic treatment) and if necessary, gingival surgery. To our knowledge, no therapeutic approach exists that promotes host-biofilm homeostasis by limiting pathogen recolonization of the oral cavity after prophylaxis or treatment. The interaction of the pathogen Porphyromonas gingivalis with commensal streptococci is critical for initiation of periodontitis and represents a target for limiting P. gingivalis colonization of the oral cavity. Previous studies showed that a synthetic peptide …
