TITLE=Orthodontic Treatment Completion and Discontinuation in a Rural Sample from North Central Appalachia in the USA JOURNAL=Frontiers in Public Health VOLUME=Volume 5 - 2017 YEAR=2017 URL=https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2017.00171 DOI=10.3389/fpubh.2017.00171 ISSN=2296-2565 ABSTRACT=Background. Orthodontics has inherent demands, requiring regular appointments and active patient engagement, but relatively little is established in regard to rates of completion of treatment and possible factors affecting successful completion. These factors may be particularly important for cultural minority groups, such as those in rural Appalachia, given the environmental, social, and economic complexities affecting access to and utilization of treatment. Design and Methods. A naturalistic study design was employed, using retrospective data from a rural outpatient general dental office. Chart abstraction yielded 219 (55.3% female) orthodontic patients (M age = 11.0[3.7]). Chi-square tests for independence were conducted for categorical dependent variables. For continuous variables, t-tests were conducted. A logistic multivariate regression analysis was conducted to predict completion/noncompletion of treatment, with age, gender, distance traveled, type of malocclusion, and payment type as predictors. Results. Overall, 49.8% of this sample successfully completed orthodontic treatment. Greater successful conclusion of treatment was found in self-pay patients (i.e., 74%) versus those whose care was funded through Medicaid/CHIP (i.e., 34%) or through private insurance (i.e., 36%). Age, gender, and distance to the office from home had no association relative to successful completion of treatment, although average one-way distance to travel for care was considerable (i.e., 38.8 miles). Conclusion. Rate of successful orthodontic treatment completion was low in this rural sample. Treatment outcome was related to the form of payment for services, with self-pay associated with the highest rate of successful completion.
