(A). Recurrent caries
(B). Class I caries
(C). Class V caries
(D). Class IV caries
The magnifier points at a dark area “under” the restoration. Those caries that come back after the tooth has been treated with restorations are called recurrent caries. This is not uncommon, and therefore it is important for us #RDH #FutureRDH to pay attention to areas under restorations when we examine the radiographs. Especially pay attention to this detail when you are taking the dental hygiene board exams (NBDHE, NDHCE). EXTRA HINT: if you are taking the CSCE, you may see this!

Answer: (A). Recurrent caries
Let’s look at the rest of caries classification according to G.V. Black:
- Class I: pits and fissures on occlusal, buccal, or lingual surface of posteriors; and lingual surface of anteriors.
- Class II: proximal surface of posteriors.
- Class III: proximal surface of anteriors.
- Class IV: proximal surface of anteriors, including incisal edge.
- Class V: gingival third of facial or lingual surface of anteriors and posteriors.
- Class VI: cusp tip of molars, premolars, or canines.
If we had to choose a type of caries lesion type from G.V. Black from the same radiograph, it would be Class II because the lesion is located interproximally on a posterior tooth. G.V. Black classification for caries is not the only way to chart caries but it is certainly one of the most commonly used tools. For this reason, the Dental Hygiene Board Exams (NBDHE, NDHCE, CSCE, WREB) may very well include questions about those classes. Make sure you know exactly what those 6 classes of caries are.
When you go take your Dental Hygiene Board Exams (NBDHE, NDHCE, CSCE, WREB), you will have the chance to write down some notes whether it is on a plastic board or computer notepad. If you think that you are going to forget, please write them down at the beginning. This would be your own cheat sheet that can serve you for the rest of the exam. Have another amazing week.
