Dental Anatomy & Terminology
The term 'apical' refers to a direction toward the:
Correct — D. Apical means toward the apex, or tip, of the root. The opposite direction, toward the chewing surface, is coronal or occlusal. -
Dental Anatomy & Terminology
Which bone forms the lower jaw and is the only movable bone of the skull?
Correct — B. The mandible is the largest, strongest facial bone and the only one that moves, articulating with the temporal bone at the temporomandibular joint. -
Dental Anatomy & Terminology
The temporomandibular joint is formed by the mandibular condyle and which bone?
Correct — A. The TMJ is formed where the condyle of the mandible meets the glenoid (mandibular) fossa of the temporal bone, with an articular disc between them. -
Dental Anatomy & Terminology
Which muscle of mastication is the primary muscle responsible for closing the jaw?
Correct — B. The masseter is a powerful muscle of mastication that elevates the mandible to close the jaw. The buccinator and orbicularis oris are muscles of facial expression. -
Dental Anatomy & Terminology
Which is the largest of the major salivary glands, located near the ear?
Correct — C. The parotid gland is the largest salivary gland and empties through Stensen duct opposite the maxillary second molar. It is the gland affected by mumps. -
Dental Anatomy & Terminology
The submandibular gland empties saliva into the mouth through which duct?
Correct — D. Wharton duct drains the submandibular gland and opens at the sublingual caruncle on the floor of the mouth near the lingual frenum. -
Dental Anatomy & Terminology
Which cranial nerve provides sensory innervation to the teeth and most of the face?
Correct — C. The trigeminal nerve (cranial nerve V) supplies sensation to the teeth, gingiva, and face and provides motor control to the muscles of mastication. -
Dental Anatomy & Terminology
In dental terminology, the prefix 'gingiv/o' refers to the:
Correct — A. Gingiv/o is the combining form for gums. For example, gingivitis means inflammation of the gingiva. -
Dental Anatomy & Terminology
The term 'edentulous' describes a patient who:
Correct — D. Edentulous means without teeth. A fully edentulous patient has lost all natural teeth and may be treated with complete dentures or implants. -
Dental Anatomy & Terminology
The suffix '-ectomy' in a word such as gingivectomy means:
Correct — B. The suffix -ectomy means surgical removal or excision. A gingivectomy is the surgical removal of gingival tissue. -
Dental Anatomy & Terminology
Which Angle classification describes a normal molar relationship where the mesiobuccal cusp of the maxillary first molar aligns with the buccal groove of the mandibular first molar?
Correct — C. Angle Class I represents a normal anteroposterior molar relationship. Malocclusions in Class II (distoclusion) and Class III (mesioclusion) deviate from this position. -
Dental Anatomy & Terminology
Which permanent tooth is typically the first to erupt, around age 6?
Correct — A. The permanent first molars usually erupt around age six, behind the primary molars, which is why they are often called the six-year molars. -
Dental Anatomy & Terminology
Which teeth are designed primarily for tearing and have a single pointed cusp?
Correct — B. Canines (cuspids) have a single, prominent pointed cusp and the longest roots, making them well suited for cutting and tearing food. -
Dental Anatomy & Terminology
Which teeth have broad occlusal surfaces with multiple cusps used for grinding food?
Correct — D. Molars are the largest teeth with broad, multicusped occlusal surfaces designed to grind and crush food during mastication. -
Dental Anatomy & Terminology
The triangular space between the proximal surfaces of two adjacent teeth, apical to the contact area, is normally filled by the:
Correct — C. The interdental papilla is the gingival tissue that fills the embrasure space between adjacent teeth, helping protect the underlying bone and contact area.
