Pennsylvania Expanded Function Dental Assistant (EFDA) Board Practice Exam

The walls of a molar are classified as the pulpal floor, buccal, distal, lingual, and mesial due to their specific orientation and function within the tooth structure. Each of these walls serves a unique purpose in the context of dental anatomy.

The pulpal floor acts as a base for the pulp chamber, providing protection and support for the dental pulp. The buccal wall is on the cheek side, while the lingual wall is on the tongue side, defining the outer boundaries of the tooth. The mesial wall faces towards the midline of the dental arch, and the distal wall is oriented towards the back of the mouth. Together, these walls provide structural integrity to the molar.

In the context of dental procedures, understanding these classifications is crucial as they help dental professionals identify the specific area of interest when performing treatments such as restorative work, extractions, or endodontic therapy. This classification is integral to the practice because it aids in the communication among dental professionals and ensures that procedures are performed accurately and efficiently.
