Today is the first of two posts on intraoral radiographic quality evaluation. For those who are looking for a series on pantomograph radiographic quality evaluation there are 4 posts that can be found here – ideal pantomograph quality, bad pantomograph quality – part 1, bad pantomograph quality – part 2, bad pantomograph quality – part 3.
There are 4 primary things we evaluate at the school on periapical radiographs.
1. The entire tooth or teeth to be captured are recorded on the radiograph.
This means that no portion of a tooth (crown or root) is cut off on the radiograph.
2. A minimum of 2mm of bone surrounding the entire root is visible.
This includes not only at the apex of a tooth but the mesial and distal aspects as well.
3. Minimal overlap of the adjacent teeth.
There should be no overlap of the roots of adjacent teeth with the exception of the the canine and first premolar roots on canine periapical radiographs. Minimal overlap of adjacent crowns are acceptable as bitewing radiographs are primarily used to evaluate for interproximal decay.
4. The roots appear longer than the crowns of the radiograph.
This means no foreshortening of the teeth on a radiograph.
This is a short and sweet post on the 4 main things we evaluate in the clinic. Next week will radiographic quality evaluation of bitewing radiographs. If you have any comments or questions, please leave them below. Thanks and enjoy!
