How many cusps does the occlusal view of the maxillary first molar contain?

The maxillary first molar is known for its distinctive morphology, which typically features five cusps when viewed from the occlusal perspective. This includes three major cusps located on the buccal side—two mesiobuccal and one distobuccal—and two smaller cusps on the lingual side—the mesiolingual and the distolingual.

The arrangement of these cusps allows for efficient grinding and mashing of food, significant for its function in mastication. The five cusps contribute to the complex occlusal surface of the maxillary first molar, allowing it to interdigitate effectively with the opposing mandibular molars during chewing processes.

This specific design differentiates it from other molars, as the other options provided do not accurately reflect the typical cusp count for this tooth type, reinforcing the importance of knowing dental anatomy in practical applications.
