The area where the roots of a multi-rooted tooth divide is called the:
Answer: Furcation

Which primary teeth are NOT replaced by permanent premolars?
Answer: Primary second molars

The lingual surface of mandibular incisors often has a shallow depression called the:
Answer: Fossa
Mandibular incisors have a lingual fossa, a shallow concave depression on their lingual surface.
Which nerve provides sensory innervation to the mandibular teeth?
Answer: Inferior alveolar nerve
The inferior alveolar nerve, a branch of the trigeminal nerve (V3), provides sensory innervation to all mandibular teeth.
Dentin makes up the bulk of the tooth and is produced by:
Answer: Odontoblasts
Odontoblasts are the cells responsible for producing and maintaining dentin throughout the life of the tooth.
The triangular space near the gingiva between adjacent teeth is called the:
Answer: Embrasure
Embrasures are the V-shaped spaces that open toward the buccal, lingual, occlusal, and gingival aspects between adjacent teeth.
