Insulators - CORRECT ANSWER-Also referred to as bases. Insulate the pulp from
thermal expansion. Examples are ZOE, Zinc Phosphate, and Zinc Poly acrylic
Reasons for Bases and Liners - CORRECT ANSWER-To protect the pulp, aid in its
recovery, or both.
Inflammation of the Pulp can be caused by the following - CORRECT ANSWER-1.
Caries
2. Traumatic Occlusion
3. Effect of Cutting Burs
4. Desiccation
5. Condensation Pressure
6. Chemical Irritation from Restorative Materials.
7. Temperature Changes
8. Dimensional Changes
9. Lack of Marginal Seal
Glass Ionomers - CORRECT ANSWER-Bonds directly to enamel, dentin, cementum,
and stainless steel. Releases fluoride. Ex: Vitrebond
Liners - CORRECT ANSWER-Thin layers of material used to protect the pulp, aid in its
recovery, or both.
IRM
(Intermediate Restorative Material) - CORRECT ANSWER-IRM material is zinc oxide
Eugenol with polymer reinforcement.
Fermit - CORRECT ANSWER-Most common for inlay/onlay preps. Will stick to adjacent
teeth. You can roll into a ball, put into prep, have patient bite down. You want the
material to stick to the adjacent teeth but not to the papilla so always make sure to
check and clean interproximal excess.

Cavit - CORRECT ANSWER-Temporary filling material that hermetically deals in
medicaments while sealing out saliva. Most common in Endo (Root Canal) procedures.
Acrylic - CORRECT ANSWER-Ideal for all temporary restorations. Ex: squash method
Examples of Temp Materials - CORRECT ANSWER-IRM/ZOE
Fermit
EZ Temp
Cavit
Acrylic
Types of Dentin - CORRECT ANSWER-Primary
Secondary
Tertiary
Bases - CORRECT ANSWER-Used in thicker amounts than liners to provide a
mechanical, chemical, and thermal protection to the pulp.
Sealers - CORRECT ANSWER-Also known as liners. Seal off openings at Dentinal
tubules to prevent pulp from getting irritated any further. Ex: Cavity Varnish which is
only used under amalgam)
Zinc Phosphate - CORRECT ANSWER-Can be used for cementation, insulating base,
also considered an insulator and reinforcer. Irritating to the pulp
Pulpitis - CORRECT ANSWER-Inflammation of the pulp. It can be irreversible if caught
early, but root canal treatment may be needed if too severe.
Obtundants - CORRECT ANSWER-Reduce the irritability of the pulp. Ex: ZOE (Zinc
Oxide Eugenol).
Transverse Ridge - CORRECT ANSWER-The Union of two triangular ridges.
Triangular Ridge - CORRECT ANSWER-Ridges that descend from the cusp tips into
the central part of occlusal surfaces. Found of molar and premolars.
Marginal Ridge - CORRECT ANSWER-Rounded borders of the enamel that form the
mesial and distal margins
Ridge - CORRECT ANSWER-A linear elevation on the surface of the tooth, named
according to its location.
Cingulum - CORRECT ANSWER-Lingual ridge at the base of an anterior tooth. Makes
up the bulk of the cervical 1/3 of the lingual surface.
Cusp - CORRECT ANSWER-Elevation in the crown of the tooth, making a division in
the occlusal surface.

Anatomic Crown - CORRECT ANSWER-Division of crown and tooth marked by the CEJ
subgingivally seen.
Clinical Crown - CORRECT ANSWER-Portion of crown visible to the eye upon clinical
examination. The part of the tooth you see when you look in the mouth.
Periodontium - CORRECT ANSWER-Tissues that surround and support the teeth.
Consists of cementum, PDL, gingiva, and Alveolar process.
Cementum - CORRECT ANSWER-Covers the roots of the teeth in a thin layer. Light
yellow in color. Joins the enamel at the cervix of the tooth - CEJ.
Primary, Secondary & Tertiary - CORRECT ANSWER-3 types of dentin. There are 3
types of dentin because dentin has the ability. For constant growth and repair.
Enamel, Cementum, Dentin, & Pulp - CORRECT ANSWER-The 4 tissues of the teeth.
Primary Dentition - CORRECT ANSWER-20 teeth total-
10 upper (A thru J)
10 lower (K thru T)
Height of Contour - CORRECT ANSWER-Protects the gingiva by deflecting food away
from the gingiva.
Height of Contour on the lingual of anterior teeth - CORRECT ANSWER-Located
Cervical 1/3
Contacts for maxillary 1st, 2nd, and 3rd molars - CORRECT ANSWER-Located middle
1/3 of the crown
Oblique Ridge - CORRECT ANSWER-It is formed by two triangular ridges extending
from the DB to the ML cusp. Located on maxillary molars only
Embrasure - CORRECT ANSWER-The spaces adjacent to and surrounding the contact
of the teeth in the same arch. They are V shaped.
Contact Areas - CORRECT ANSWER-Serve two purposes: to keep food from packing
between the teeth and to help stabilize the dental arches
Enamel - CORRECT ANSWER-Hardest tissue in the body and is very brittle.
Dentin - CORRECT ANSWER-The bulk of the tooth is made up of Dentin which is the
second hardest tissue in the body. Dentin is darker than enamel.
Dental Pulp - CORRECT ANSWER-Provides the developmental, protective and sensory
mechanism of the tooth: sustains the life of the tooth.
