Advanced dental education programs: status and implications for access to care in California.

Primary care residencies in dentistry include general practice residency and advanced education in general dentistry--collectively known as postdoctoral general--dentistry and pediatric dentistry. These primary care programs are the most likely to serve underserved populations during the training experience. An expansion of primary care dental residency positions in California has the potential to positively impact access to care in California. However, there are significant political and financial barriers to realizing this potential.
