Yes, apes possess sectorial premolars, which are adapted for shearing food. In particular, the upper first premolar often has a blade-like structure that works in conjunction with the lower molars to process tough plant material. This dental adaptation is characteristic of their omnivorous diet, allowing them to effectively grind and slice food.
