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.
These are the average fees charged according to the ADA's 2012 dental fee survey (not including the top or bottom 5%). Assuming there are no major problems, a check-up-including the examination, scale and clean, and a fluoride treatment-should be about $200.
