Today we are joined by Janet Simpson of to discuss Dental Radiography, improving the diagnostic quality of your radiographs and much more!

Obtaining quality radiographs would be easy if all our patients had big mouths, nice wide arches, high palettes, and straight teeth. However, we often have crowded arches, malposed and rotated teeth, touching gag reflexes, pushy tongues, chubby cheeks, and patients who tend to be exasperated or uncooperative. To make things even more difficult the wired sensors are smaller, harder, bulkier, more uncomfortable than film and black or dark blue. To top it off dental assistants that have been trained on the job "learned" to take dental X-rays in one weekend. They were never taught the secrets of shadow casting, or bisecting. My mission is to help.

I've been a speaker, but would like to focus more of my attention to in person coaching.

My co-worker Darlene is an RDAEF with over 40 years in dentistry. She and I want to spend more time in dental offices coaching dental assistants in all aspects of their job.
