Demands for increased health care coordination and cooperation have been raised for a long time in Germany. Over the past years, the public health services in the federal states have initiated networks at the regional level dealing with health-related topics, namely health conferences and health regions. In the areas of health promotion and prevention, health care services and nursing care sector, these networks make an important contribution to regional planning and management by setting up networks among relevant municipal players and developing a more comprehensive approach.

Introduction: Bracket loss during the later stages of orthodontic treatment is a relatively frequent occurrence. The purpose of this study was to evaluate and isolate the effect of composite aging, one of many factors that can contribute to decreased bond strength during a normal 24-month orthodontic treatment period.
Methods: Two orthodontic bonding adhesives--Transbond APC II (3M Unitek, Monrovia, Calif) and Quick Cure adhesive (Reliance Orthodontic Products, Itasca, Ill)--were used to bond brackets to 280 bovine incisors that were stored in distilled water at 37 degrees C for 30 minutes, 24 hours, and 1, 6, 12, 18, and 24 months before shear-peel testing.
Introduction: A survey was conducted in 2006 to determine, on a state-by-state basis, the availability of Medicaid-funded orthodontic treatment and, when available, the criteria and the funding rates.
Methods: All 50 states were contacted by e-mail, telephone, or standard mail to obtain answers to the following questions. Does your state provide Medicaid coverage for orthodontic services? What qualifications are required to be reimbursed? What is the patient cutoff age for reimbursement of services? Is an index used to assess malocclusion? If so, which index? What is the primary training of the reviewer? How are services reimbursed? Is limited treatment covered? Is interceptive treatment covered? What is the total amount reimbursed for 24 months of treatment for comprehensive adolescent care?
Results: Wide variations of responses were received from the states, with no statistical significance between any questions based on geographic regions or reimbursement rates, although some trends appeared to exist.
