How is the anatomical tooth divided?

The anatomical tooth is divided into thirds. This method of division allows for a detailed description of tooth anatomy and helps dental professionals communicate effectively when diagnosing or planning treatment. The three segments of the tooth are the cervical third (near the gum line), the middle third, and the occlusal or incisal third (the biting surface). This division is crucial in understanding tooth morphology and the relations between different parts of the tooth during procedures such as restorations or extractions.

The other options may refer to different ways of conceptualizing teeth or their sections but do not accurately represent the standard anatomical classification used in dentistry. Understanding the third division is essential, as it aids dental practitioners in enhancing patient care through more precise procedures and assessments.
