Lecture 3 Radiographic anatomy part 1 Flashcards
What is the labelled arrow?
Root canal
Labelled arrow?
Root canal
Are these root canals visible in the last 2 mm?
Is the cementum discernible?
Frequently not visible in the last 2 mm.
Cementum is not discernible since it has same density of dentine.
What is this?
Cervical burnout.
- Overexposure of lateral portion of roots between enamel and alveolar crest.
What is this?
Cervical burnout
