Which term describes the back of the mouth or the back teeth?

• A. Periodontal
• B. Posterior
• C. Proximal
• D. Radiograph

Answer: (B)

Posterior refers to the back portion of the mouth or the back teeth. In dental terminology, the front teeth are called anterior, while the back teeth—premolars and molars—fall into the posterior region. This term is commonly used in charting and treatment planning to specify the area being talked about. The other terms describe different concepts: periodontal relates to the gums and supporting structures around teeth, proximal refers to surfaces between adjacent teeth, and radiograph is an X-ray image used for diagnosis, not a location descriptor.
