Which direction does the oblique ridge run?

• A. From the MB cusp to the DB cusp
• B. From the DB cusp to the ML cusp
• C. From the ML cusp to the DL cusp
• D. From the cusp of Carabelli to the buccal groove

Answer: (B)

The oblique ridge is a feature typically found on the maxillary molars, consisting of two facial and lingual cusps. It runs diagonally across the occlusal surface, connecting specific cusps in a way that contributes to the overall function and stability of the tooth during chewing. The correct answer describes the oblique ridge as running from the distobuccal (DB) cusp to the mesiolingual (ML) cusp. This orientation is significant, as it influences the strength and structural integrity of the tooth during occlusion and mastication. The relationship between these two cusps allows for effective force distribution when biting or grinding food, which is critical in maintaining oral health and function. Understanding the oblique ridge's direction is essential for dental professionals in treatment planning, as preserving this ridge during procedures can help maintain the tooth's natural function and align with its anatomical and biomechanical principles.
