(D.) Dens in dente
Mini Boards Reviews for the National + Local Anesthesia + CSCE Dental Hygiene Boards Exams!
- Dens in dente (also called dens invaginatus) is formed as the enamel organ goes into the crown of a tooth before mineralization is completed. Radiographically, a tooth-like structure appears within the crown. Due to the irregularities of the crown structure, the tooth is more vulnerable to caries and infections, including periapical lesions. Dens invaginatus is most common with maxillary lateral incisors.
- Gemination is when one crown splits into two, creating two crowns.
- Fusion is the combination of two tooth buds with separate canals.
- Concrescence occurs when roots adhere together by cementum only.
Answer: (D.) Dens in dente
Now, you may have noticed that this does NOT really look like a “tooth” within the tooth. It may just look like some radiopacity inside the tooth. For this reason, when you are taking the dental hygiene board exams (NBDHE, NDHCE, CSCE, WREB, CRDTS), look very carefully. Also look at the keywords “maxillary lateral incisors” too that could be a hint to dens in dente.
