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.

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.

Cavity EXCEPT One. Which One Is The EXCEPTION?
a. Fovea Palatinae
b. Tonsillar Pillars

ANS: C
The Laryngeal Pharynx Is Located Below The Oral Pharynx And Cannot Be Seen While
Examining The Oral Cavity. The Fovea Palatinae, The Tonsillar Pillars, And The Sublingual
Fold Can Be Seen When Examining The Oral Cavity. Fovea Palatinae Are Small
Depressions In Mucosa On Either Side Of The Posterior Nasal Spine Indicating The Junction
Of The Hard And Soft Palate. Tonsillar Pillars Are Folds Of Tissue That Partially Surround
The Tonsils. The Sublingual Fold Extends

The Anterior And Posterior Pillars Are Located Posterior To The Soft Palate. The Posterior
Pillar Is Also Called The Palatopharyngeal Arch Or Fold. The Anterior Pillar Is Also Called
The Palatoglossal Arch Or Fold. The Tonsils Lie Between The Anterior And Posterior
Pillars.

9. The Small Bony Growths That Commonly Occur On The Buccal Cortical Plate Of The
Maxillae And The Mandible Are Called
a. Torus Palatinus
b. Mandibular Tori
c. Exostoses
d. Maxillary Tuberosity
ANS: C
Exostoses, Small Bony Growths That Occur On The Buccal Cortical Plate On The Mandible
And The Maxillae, Are Seen In A Large Portion Of The Population. They Are Normally
Inconsequential Unless They Become Tender Or A Denture Is Needed. Exostoses Occur
More Frequently On The Mandible Than On The Maxillae.
Torus Palatinus Are Excess Bony Growths That Commonly Occur In The Midline Of The
Palate. Mandibular Tori Are Bony Swellings That Frequently Occur On The Lingual Surface
Of The Mandible At The Canine Area. The Maxillary Tuberosity Is A Rounded Bony
Protrusion In The Area Of The Third Molar.

c. Labial Frenum
d. Gingiva
ANS: B
The Alveolar Mucosa, A Thin Layer Of Loosely Attached And Movable Tissue, Covers A
Highly Vascular Area. The Presence Of Blood Vessels Immediately Under This Relatively
Thin Mucosa Is Responsible For The General Reddish Color. By Contrast, The Mucogingival
Junction That Divides The Attached Gingiva From The Alveolar Mucosa Appears More Pink
In Color. The Gingiva And Labial Frenum Also Appear Pink In Color.

11. Although A Patient Presenting With Painful Areas Throughout The Oral Cavity Or A Child
Presenting With Gingival Bleeding In The Presence Of Excellent Oral Hygiene Should Be
Monitored Carefully, Referral To A Dental Specialist Or Physician Is Not Indicated. A
Patient With A Red And Painful Tongue Does Warrant Such A Referral As Does A Patient
With Moderate Plaque On All Teeth.
