Compact or dense bone; lines the outer layers of the maxilla and mandible
What is Cortical Bone
100
Thin radiolucent line that traverses down the center of the palate at the junction of the right and left maxilla
What is the Median Palatine Suture
100
The formation of sclerotic bone as a result of infection; appear more radiopaque that the surrounding bone areas; generally irregular in shape or location
What is Condensing Osteitis
100
Caries that involve the buccal or facial surface of a tooth
What are Buccal Caries
100
Consists of 32 teeth
What is the Permanent Dentition
200
Fibers that attach the teeth to the alveolus; soft tissue so appears radiolucent; appears as dark line between the tooth and alveolus
What is the Periodontal Ligament Space (PDL)
200
A broad "U" or "J" -shaped radiopaque band seen above or superimposed over the roots of the maxillary first and second molars
What is the Zygomatic Process
200
Periapical infection usually from pulpal inflammation
What is a Periapical Abscess
200
Caries that are no longer active
What are Arrested Caries

What are Supernumerary Teeth
300
A tiny radiolucent dot indicating the small opening in the tubelike passageway of a nutrient canal
What is a Nutrient Foramen
300
Union of lateral border of nasal fossa and anterior wall of maxillary sinus; radiopaque intersection in the canine-premolar area
What is the Inverted "Y"
300
A tooth root that is misshapen with a sharp bend
What is a Dilaceration
300
Caries that develop between the enamel border and the free margin of the gingiva on the cemental surface; bone loss and recession of the gingival tissue are necessary for the caries' process to start
What are Root Caries of Cemental Caries
300
The process of shedding of the primary teeth to make room for the erupting permanent teeth
What is Exfoliation
400
Only non-calcified tooth tissue; appears radiolucent, in the center of the root
What is the Root Chamber or Root Canal
400
Four small bony crests on the lingual surface of the mandible that serve for muscle attachment; appears as round radiopaque "doughnut," apical to mandibular central incisors
What are the Genial Tubercles
400
Calcified microbial plaque
What is Calculus
400
Caries that penetrate less than halfway through the enamel of the tooth toward the DEJ; C-1
What are Incipient Caries
400
A congenital absence of teeth
What is Anodontia
500
Fairly uniform, thin radiolucent lines that may exhibit radiopaque borders; contain blood vessels and nerve supply to the teeth, bone, and gingiva; often more prominent in anterior of amndible due to decreased thickness of bone
What are Nutrient Canals
500
Located on the lateral surface of the mandible; appears as a horizontal radiopaque line extending from the premolor area region to the symphysis (the midline of the mandible where the left and right sides of bone are fused together)
What is the Mental Ridge
500
Advanced stage of periodontal disease; >50% bone loss; characterized radiographically by severe horizontal and/or vertical bone loss
What is Type IV or Severe/Aggressive Periodontitis
500
An optical illusion/radiolucency caused by overlapping images of the teeth
What is the Mach Band Effect
500
Plates of bone that form a network of various-sized compartments that account for the honeycomb appearance of bone; filled with fat, blood, or bone cells
What is Trabeculae (Trabecular Bone/Cancellous Bone)
