LESSON 7 Flashcards
Radiographically, enamel will appear as a radiopaque structure of the tooth
Enamel, Dentin and Pulp
appears as less radiopaque area at the cervical area of a tooth due overexposure of the lateral portion of the teeth between enamel and alveolar crest.
Cervical burnout
a less radiopaque structure found at the apex or sometimes 2mm.
Root canal opening (Apical foramen)
a radiopaque structure that lines the root of every tooth present.
Lamina dura
is radiopaque area that represent the gingival margin of the alveolar process
Alveolar crest
a radiolucent area that surrounds the root of every tooth present in the mouth.
Periodontal ligament space
radiopaque structures that shows the normal appearance of the surrounding bones
Bony trabecular pattern
a radiolucent structure that is found in between the two maxillary central incisors.
Intermaxillary suture
is seen as radiopaque v-shaped projection from the floor of the nasal aperture in the midline
Anterior nasal spine
is a radiopaque structure above the anterior nasal spine
Nasal septum
is a radiopaque structure below the nasal fossa.
Floor of the nasal fossa
appears as an ovoid radiolucency between the roots of the maxillary central incisors.
Incisive foramen
is a diffuse radiolucency in the region of the apex of the maxillary lateral incisor.
Lateral fossa
is the largest of the paranasal sinuses that appear as radiolucent area
Maxillary sinus
in a radiograph it appears as a u-shaped radiopaque line with its open end directed superiorly.
Zygomatic process
is a radiopaque structure posterior to the maxillary tuberosity.
Hamular process
in infants, appears as radiolucent line through the midline of the jaw
Mandibular symphysis
appears as radiopaque mass in the midline below the incisor roots.
Genial tubercle
it is an opening on the lingual surface of the midline of the mandible in the region of the genial tubercle.
Lingual foramen
seen as radiopaque ridge on the anterior surface of the mandible.
Mental ridge
is a radiolucent depression on the anterior surface of the mandible between the alveolar ridge and mental ridge.
Mental fossa
appears as an oval radiolucency near the apex of the mandibular second premolar.
Mental foramen
is a dark linear shadow (radiolucent) with thin radiopaque superior and inferior borders
Mandibular canal
appear as radiolucent lines o f fairly uniform width
Nutrient canal
appears radiopaque but quite difuse and of varable width
Mylohyoid ridge
It is a continuation of the anterior border of the mandibular ramus.
External oblique ridge
it is at lingual surface of the mandibular body
Submandibular gland fossa
is characteristically dense, broad radiopaque band of bone.
Inferior border of the mandible
it serves as reinforcement for a restorative materials.
Stainless steel pins
obturating material use in endodontic treatment that appears radiopaque.
Gutta percha and silver points 3C
generally appears radiopaque on radiograph.
Base material
The coping of the crown is radiopaque since it is made of metal and the porcelain crown is less radiopaque.
Porcelain crown
It is because silicate has no fillers and quarts which composite possess for reinforcement.
Silicate and composite restorative material
