Which dentition type is described as rounded cusps and lower crowns, typical of omnivores?

• A. Hypsodont
• B. Bunodont
• C. Selenodont
• D. Secodont

Answer: (B)

A dentition with rounded cusps and low crowns is optimized for grinding a variety of foods, not specialized slicing or tearing. That combination—broad, rounded chewing surfaces that stay relatively short in height—fits an omnivorous diet, wheremasticating plants and animal matter requires generalist grinding rather than extreme wear resistance or sharp slicing. This type is called bunodont. In contrast, teeth with tall crowns (hypsodont) are built to endure heavy wear from abrasive plant material; teeth with crescent-shaped ridges (selenodont) are adapted for shredding fibrous vegetation; and sharp, blade-like crests (secodont) suit tearing meat.
