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.

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.

Obj: To Define The Terms Vestibule, Oral Cavity Proper, Mucobuccal Fold, Frenum, Alveolar
Mucosa, Gingiva, Exostoses, Torus Palatinus, And Torus Mandibularis

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.

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 Includes
The Region From The Floor Of The Mouth Upward To The Hard And Soft Palates.

5. Each Of The Following Is True Of The Uvula Except One. Which One Is The Exception?
a. It Is Located At The Most Posterior Portion Of The Hard Palate.
b. It Is Located At The Midline.
c. It Is A Downwardly Projecting Muscle.
d. It Is Necessary For Swallowing.
Ans: D
The Uvula Is A Downwardly Projecting Muscular Tissue Located At The Midline Of The
Most Posterior Portion Of The Hard Palate. It Is Not Necessary For Swallowing.
