Vocabulary Flashcards
is the study of the anatomy, growth, and diseases of the teeth.
odontology
sets of teeth: a primary,or deciduous, dentition, and permanet, or succedaneous, dentition.
dentitions
this is the section of the tooth that is visible in the mouth. It is protected on the outside by the tissue called enamel.
crown
This is the section of the tooth below the gingiva, or gums. It is covered on the outside by the tissue called cementum. It is not usually visible in the mouth. It helps anchor or hold the tooth in the bony socket of the jaw.
root
The area where the enamal covering the crown meets the cementum covering the root.It is the narrow section where the crown meets the root.
cervix
This is the tip of the root of the tooth. It contains an opening through which nerves and blood vessels enter the tooth.
apex
An opening in the apex through which nerves and blood vessels enter the tooth.
apical foreman
This is the hardest tissue in the body and covers the outside of the crown. It is made up mainly of calcium and phosphorus, and forms a protective layer for the tooth. Once the tooth is fully developed, the enamel cannot grow or repair itself.
enamel
Bone like structure covering the root of the tooth.
cementum
bone like substance which makes up the bulk of the tooth and surrounds the pulp.
dentin
structure inside central cavity of tooth that contains connective tissue, blood vessels and nerve fibers.
pulp
All of the supporting structures both hard and soft of a tooth. Includes: Periodontal Ligament, Cementum, Gingiva, and Alveolar bone.
periodontium
This is the name for the portion of the two maxillary bones and the mandible that contain the alveoli for the teeth.
alveolar process

periodontal ligament
the specialized mucous membrane that surrounds the teeth, covers the bone of the dental arches, and lines the cheeks.
gingiva

incisors
Canines, have sharp points to tear food and have the longest root than any other teeth.
cuspids
aka premolars. have two cusps (grinding surfaces), and the upper sometimes have two roots, but the bottom teeth have a single root. are not present in primary dentition.
bicuspids
Large somewhat flat-topped back teeth. Function to grind food. largest and stongest teeth.
molars
consists of 20 teeth that are normally lost during childhood and are replaced by the permanent teeth. these include: 8 incisors, 4 canines, and 8 molars
primary
four sections: maxillary right, maxillary left, mandibular right, and mandibular left.
quadrants
pertaining to the upper jaw and teeth.
maxillary
Pertaining to the lower jaw bone and teeth.
mandibular
Sixteen maxillary (upper) 2 central incisors, 2 -2nd molars, 2 lateral incisors, 2 -3rd molars,2 cuspids, 2- 1st bicuspids, 2 -2nd bicuspids, 2 -1st molars.
permanent
means “toward the front.” The teeth in the front of the mouth: incisors and cuspids
anterior
means “toward the back.” The teeth in the back of the mouth: bicuspids and molars.
posterior
crown surface next to the lips.
labial
crown surface next to the tongue.
lingual
cutting or bitting edge of the tooth
incisal
side surface closest to or facing toward the midline.
mesial
side surface away from the midline.
distal
crown surface next to face or cheek.
buccal
crown surface next to the tongue.
lingual
chewing or grinding surface of the tooth.
occlusal
form where two crown surfaces meet.
line angles
form where three crown surfaces meet.
point angles
are mounted on the ceiling of the dental unit or attached to the dental chair. used to illuminate the oral cavity, or mouth, while the doctor works.
dental lights
is designed to postion the patient comfortably while providing the doctor and the dental assistant with easy access to the oral cavity.
dental chair
provides air pressure to operate the handpiece and the air syringes on the dental units.
air compressor
uses water to provide the dental units with suction action. It aids in removing particals, debris, and liquids from the oral cavity.
oral-evacuation system
vary from office to office, but most contain the same basic equipment.
assistant’s carts
This is also called a three-way syringe. It provides air, water, or a combination of air and water fro various dental procedures.
air-water syringe
This provides constant, low-volume suction to remove saliva and other fluids from the mouth.
saliva ejector
this is a bowl or cup that can be used to allow the patient to expectorate (spit out) particals and water.
cuspidor
also vary from office to office. many contain air-water syringes in addition to a variety of handpieces.
doctors’ carts
or foot controls used to operate the handpieces.
rheostats
This is used fro cutting and polishing during various dental procedures.
contra angles
instruments that are inserted into the contra angle. Used to cut , shape, finish, and polish teeth, restoration and dental appliances.
burs
This attachment holds polishing cups, disks, and brushes that are used to clean the teeth or to polish restorations.
prophylaxis angle
This is used to do most of the cutting and preparation of the tooth during dental procedures.
High-speed handpiece
prevention of decay.
carious lesions (caries)
is a thin, tenacious, flimlike deposit that adheres to the tooth and can lead to decay; it contains microorganisms and protien substance.
plaque
bad breath.
halitosis
is a negative reproduction of a tooth, or dental arch. it is taken to form a model of the area foor restorative treatment that will take place outside of the mouth.
impression
is a positive reproduction of the arches or teeth that is created from the negative impression.
model
is an irreversible hydrocolloid impression material. It cannot be retured from a gel to its original state.
alginate
is an elastomeric impression material that is elastic and rubbery in nature.
rubber base (polysulfide)
final impression material that is odor free and easy to work with.
silicone
it is used mainly where strength is not a critical factor, such as for study modelsand perliminary models.
plaster
it produces a stronger, more regular and uniform model.
stone
are impression trays made to fit a particular patient’s mouth.
custom trays
which means “absence of feeling” is the term used to describe the condition that exist when the sensation of feeling pain has been decreased or eliminated.
anesthesia
are glass cylinders that contain premeasured amounts of anesthetic solutions.
anesthetic carpules
are commonly used to inject local anesthetic.
aspirating syringe
material used to cover, line, or seal exposed tooth tissue, such as dentin. it is usually in the form of a varnish.

cavity
is a restorative material used primarily on posterior teeth.
amalgam
is the restorative material used most frequently in the repair of anterior teeth, but it can also be used to restore posterior teeth.
composite
are negatives taken of the teeth, similar to the negatives received when photograph are taken. x-ray beams are passed through the teeth and tissues. A series of shadows are then produced on film.
radiographs
these areas appear dark on radiographs . This means that the X-ray penetrates through the structure.
radiolucent
these areas appear light or white on radiographs. this means that the structures stop the X-rays, or that the X-rays are unable to penetrate the structures.
Radiopaque
these show only the crowns of the maxillary and mandibular teeth. They are called cavity-detecting radiographs because they are primarily used to detect interproximal decay and recurring decay under restorations.
