Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Aim 1. To compare orthodontic outcomes, facial body image, and quality of life between Medicaid participants who receive early orthodontic treatment and those who do not. 1.a To compare the level of understanding and compliance between early treatment subjects given information about the goals, risks and benefits of the planned treatment one-on-one by an orthodontist, with subjects who also use an interactive CD-ROM to provide this information. This will be referred to as the Informed Consent Study and should not be confused with the routine informed consenting process used to enroll subjects into the overall study.Aim 2. To compare orthodontic outcomes, facial body image, and quality of life between Medicaid-funded and private-pay patients who receive full orthodontic treatment at adolescence.Aim 3. To compare orthodontic outcomes, facial body image, and quality of life between Medicaid-funded patients who receive early orthodontic treatment only and Medicaid-funded participants who receive full orthodontic treatment at adolescence. Relationship of this project with the Disparity Center theme. Two of the goals of the Northwest and Alaska Center for Oral Health Disparity are met by this study. The first is to conduct clinical research to evaluate the efficacy of interventions to prevent and treat oral diseases and conditions in children. The second is to develop community-based research that translates existing knowledge and new information regarding children and their caretakers into new technologies and interventions that hold promise for reducing disparities. Today, children of low-income families have very limited access to orthodontic treatment. We also know that some relatively simple interventions done during the mixed dentition can be effective at reducing the severity of malocclusion. This study is designed to examine how effective these early orthodontic interventions are in a Medicaid population. It will also examine how outcomes from early treatment in Medicaid patients compare to the more complex approach of complete orthodontic treatment in the permanent dentition. Many orthodontists perceive that Medicaid patients are at risk for poor outcomes, and limit access as a consequence. The follow-up component of this study will address this issue by making a comparison between Medicaid and private-pay patients treated in similar environments. We expect that significantly greater access to orthodontic services could be provided for Medicaid patients by the more widespread use of simpler, more timely interventions. This study will provide data on the trade-off between simple, timely partial treatments, versus complete full treatments. In response to the second theme of the Disparity Center, the use of interactive CD-ROMs that provide treatment information at the comprehension level of young patients and their parents, and in a culturally appropriate manner, will be examined. We expect this approach will improve patient and parent understanding of the proposed treatment, as well as enhancing compliance with treatment procedures in order to assure successful outcomes.
