This week I will be going over other radiographic findings that should be noted as they are irritating to the surrounding soft tissue.
There are two entities in this category to be aware of; open contacts and calculus. Open contacts can be either natural (as seen in the first radiograph) or man-made (as seen in the second radiograph). Open contacts allow food to be trapped, which if not cleaned properly will irritate the soft tissues. Open contacts present as a radiolucent vertical line between two adjacent teeth. The radiolucency is that of air.
Calculus typically presents as a well-defined triangular radiopaque entity near the cemento-enamel junction. It may also present as a well-defined radiopaque mass near the cemento-enamel junction. This appearance is more commonly seen with heavy calculus buildup. The radiopacity of calculus is less than that of enamel indicating it is not normal tooth structure.
Man-made irritating factors have a slightly longer list; open contacts as noted above, overhanging margins, open margins, and over-contoured or bulbous restorations. First will be overhanging margins. Don’t even need to describe it. Just look below and I’m sure you can find it. 🙂
This is all for the periodontal radiographic assessment series. If you have any questions or comments or want more topics covered, please leave them below. Thanks and enjoy!
