MULTIPLE CHOICE
1. A Diastema Is A Space Between Two Teeth In The Same Arch. When This Occurs
Between The Maxillary Central Incisors, It Is Often The Result Of A Pronounced Labial
Frenum.
A. Both Statements Are True.
B. The First Statement Is True; The Second Statement Is False.
C. The First Statement Is False; The Second Statement Is True.
D. Both Statements Are False.
ANS: A
A Space, Or Lack Of Contact Area, Between Any Two Teeth In The Same Arch Is
Called A Diastema. When A Diastema Occurs Between The Maxillary Central Incisors,
It Is Often The Result Of A Pronounced Labial Frenum Extending To The Crest Of The
Alveolar Ridge And Possibly Over The Ridge. This Band Of Firm Connective Tissue
Causes The Erupting Incisors To Be Pushed Aside Resulting In A Diastema, Or Space.
Correction Of A Diastema Usually Involves Surgical Removal, Or Cutting, Of The
Frenal Tissue Between Teeth.
(B) Incorrect. The Second Statement Is Also True Because A Pronounced Labial Frenum
Can Cause Spacing.
(C) Incorrect. The First Statement Is True, So This Option Is Wrong.
(D) Incorrect. Both Statements Are Accurate According To Dental Anatomy Principles.

Structures In Each Area

Limited To: Oral Cavity. Top: Bloom: Remembering
2. Torus Palatinus Is Seen On The
A. Soft Palate
B. Hard Palate
C. Alveolar Ridge
D. Oral Pharynx
ANS: B
Torus Palatinus Is Excess Bone Growth And Occurs In The Midline Of The Hard Palate.
It May Grow To Varying Sizes And Is Generally Only A Problem When The
Construction Of A Maxillary Denture Is Necessary. In Health, Such Bony Protuberances,
Or Excess Bone Growths, Do Not Occur On The Soft Palate, Alveolar Ridge, Or Oral
Pharynx.
(A) Incorrect. The Soft Palate Consists Of Muscle And Connective Tissue, Not Bone, So
Bony Growths Like A Torus Cannot Occur Here.
(C) Incorrect. While Exostoses (Bony Growths) May Occur On The Alveolar Ridge, The
Term Torus Palatinus Specifically Refers To The Hard Palate.
(D) Incorrect. The Oral Pharynx Is A Muscular Area Posterior To The Oral Cavity; No
Bony Growths Occur There.

3. Contraction Of Which Muscle Raises The Tongue Upward?
A. Mylohyoid
B. Palatopharyngeal
C. Palatoglossal
, D. Levator Glossal
ANS: A
Contraction Of The Mylohyoid Muscle Raises The Tongue. The Palatopharyngeal
Muscle And The Palatoglossal Muscle Form The Posterolateral Borders Of The Oral
Cavity. There Is Not A Muscle By The Name Of Levator Glossal.
(B) Incorrect. The Palatopharyngeal Muscle Helps Close The Nasopharynx During
Swallowing But Does Not Elevate The Tongue.
(C) Incorrect. The Palatoglossal Muscle Elevates The Posterior Portion Of The Tongue
But Primarily Assists In Closing Off The Oral Cavity From The Pharynx During
Swallowing.
(D) Incorrect. There Is No Anatomical Muscle Named “Levator Glossal.”

4. The Oral Vestibule Is Partially Bordered By The Lips And Cheeks. The Oral Cavity
Proper Extends Posteriorly To The Soft Palate.
A. Both Statements Are True.
B. The First Statement Is True; The Second Statement Is False.
C. The First Statement Is False; The Second Statement Is True.
D. Both Statements Are False.
ANS: B
The Oral Vestibule Is The Space Or Potential Space That Exists Between The Lips Or
Cheeks And Teeth. In An Edentulous Person, The Vestibule Would Extend Between The
Lips Or Cheeks And The Alveolar Ridges. The Oral Cavity Proper Is Surrounded By
Teeth Or Alveolar Ridges And Extends All The Way Back To The Palatine Tonsils. This
