Final answer:
The teeth that have a longer mesial cusp ridge of the facial cusp than the distal cusp ridge are the maxillary central incisors, which are used for biting into food. So, the correct option is a) Maxillary Central Incisors
Step-by-step explanation:
The tooth type that has the mesial cusp ridge of the facial cusp longer than the distal cusp ridge of the facial cusp is the maxillary central incisors. These are the sharp front teeth used for biting into food.
The mesial cusp ridge is towards the midline of the face, and the distal cusp ridge is away from the midline.
Maxillary central incisors are characterized by having a longer mesial cusp ridge, which is significant in their anatomy and function.
Unlike the maxillary central incisors, the mandibular first molars, maxillary first premolars, and mandibular canines do not generally exhibit this feature as distinctly.
Therefore, the correct option is a) Maxillary Central Incisors
