Extra And Intra Oral Anatomy

Front 1

Radiolucent

Back 1

Dark-to-black areas on a processed radiograph that results from the passage of radiant energies through less dense/ soft areas.
Examples: pulp, dental caries foramen

Front 2

Radiopaque

Back 2

Light-to-white areas on a processed radiograph that results from radiant energies penetrating more dense structures.
Example: amalgam and gutta percha

Front 3

Intraoral

Back 3

inside the oral cavity

Front 4

Amalgam Restoration

Back 4

A form of/dental restoration that uses a combination of two or more metals, one of which is mercury; a blend of powerful ,metal alloy and mercury to produce a restorative material.

Front 5

Composite Restoration

Back 5

A form of dental restoration that uses resin restorative material that is hardened by chemical or light curing

Front 6

Midsagittal Plane (midline)

Back 6

An imaginary vertical plane that equally separates the body into left and right halves ; often referred to as the midline

Front 7

Alveolar Process

Back 7

The extension of the maxilla and mandible that surrounds and supports the teeth from the dental arches

Front 8

Panoramic Radiograph

Back 8

an extra oral radiograph taken to expose the maxillary and mandibular arches, tempormandibular joints and associated anatomy on a single film

Front 9

Computed Tomography (CT)

Back 9

An imaging technique that isolates an area or '' slice '' of tissue while blurring out other structures

Front 10

Extraoral

Back 10

Outside the mouth ; frequently used in reference to orthodontic appliances that extend outside of the mouth ; dental radiographs such as panoramic and chephalometric exposures

Front 11

Superimposed

Back 11

In an Cray image, when one image is shown on to of another

Front 12

Periapical Exposure

Back 12

Pertaining to around the apex ; radiograph that exposes the entire tooth and surrounding tissues

Front 13

Alveolar Ridge

Back 13

Bony ridge of the maxilla and mandible that contains sockets of the teeth and support the teeth

Front 14

Enamel

Back 14

The calcified structure that covers the crown of the tooth and protects the dentin; the hardest calcified tissue in the human body; appears radio plaque on radiographs and digital images

Front 15

Dentin

Back 15

Mineralized tissue that makes up the main body of the tooth and extends the entire length of the tooth to protect the pulp ; covered by enamel at the crown of the tooth and by cementum at the root

Front 16

Dentinoenamel Junction

Back 16

The Lind of demarcation where the enamel and dentin meet; not distinguishable on an x-ray

Front 17

Pulp

Back 17

The interior of the tooth, which contains nerves, b
blood vessels and lymphatic tissue; appears radiolucent on radiographs and digital images

Front 18

Periodontal Ligament

Back 18

Connective tissue that supports and suspends the teeth in their position within the dental arch; generally, the periodontal
ligament fiber attach to the lamina dura, lining the bone of the tooth socket (alveolus) and the cementum of the root; appears as a thin radiolucent links between the cementum and the lamina dura of the alveolar bone radiographs and digital images

Front 19

Alveolar Bone

Back 19

The bone that surrounds and supports the tooth in its position in the jaw; appears radiopaque on radiographs and digital images

Front 20

Apical Foramen

Back 20

An opening in the apex of the tooth that provides for the access of nerves, blood vessels and lymphatic; not easily distinguishable on radiographs and digital images

Front 21

Cementoenamel

Back 21

The area where the cementum of the tooth meets the enamel of the crown; not usually distinguishable on radiographs and digital images

Front 22

Alveolar Crest

Back 22

The most coronal portion of the alveolar bone; where the two cortical bones join between each tooth; a liner radiopaque outline of the alveolar ridge can be seen on radiographs and digital Images

Front 23

Cementum

Back 23

A calcified tissue covering the tooth of the tooth; the periodontal ligament attaches to the cementum to anchor the tooth within the socket; usually not distinguishable on radiographs and digital images

Front 24

Lamina Dura

Back 24

The bony wall of the tooth a socket that surrounds the root; on radiographs and digital images, the lamina dura appears as a thin radiopaque line around the root.

Front 25

Apex or Apices

Back 25

The tip of the root of the tooth; usually seen as a continuation of the radiopaque outline of the root.
