It is important to remember that there is a wide range of normal variability in the 12 lead ECG. The following normal ECG characteristics, therefore, are not absolute. It takes considerable ECG reading experience to discover all the normal variants.
Check-Ups. Common check-up and cleaning costs vary. Dentists charge different rates depending upon your situation and where you live. In most places, an average check-up costs about $288, which covers an exam, x-rays and cleaning.
A single dental x-ray would cost between $15-25. Four check-up or bitewing x-rays may cost between $50-$100, and a full mouth series (18 x-rays) or panoramic x-ray would cost between $100-200.
