What surfaces does the oblique ridge run from?

The oblique ridge is an important anatomical feature found on the occlusal surface of maxillary molars. It runs specifically from the mesiolingual cusp to the distobuccal cusp. This ridge is formed by the union of these two cusps, which facilitates the proper occlusion and function during mastication.

Recognizing that the oblique ridge connects the mesiolingual cusp with the distobuccal cusp helps illustrate why the selected choice is correct. Understanding the orientation of these cusps allows for a better grasp of occlusal anatomy, which is critical in dental hygiene practice and assessments.

In contrast, the other options do not accurately describe this specific topographical relationship found on maxillary molars. The alignment proposed in those choices either mixes the cusps incorrectly or does not reflect the precise anatomical positioning that defines the oblique ridge. By focusing on the correct anatomical landmarks, future dental hygienists can improve their clinical skills and knowledge of dental structures.
