lecture 11 - identification of pathology Flashcards
periapical lesion
around the root
inter-radicular lesion
between two adjacent roots
edentulous zone lesion
where a tooth isn’t present
pericoronal lesion
around crown of tooth of an impacted tooth
what do we measure lesions size in
millimeters or centimeters
unilocular - RL lesions
one compartment, small
outlined in cortical bone
corticated - RL
benign, slow growing
outlined in cortical bone
non corticated - RL
benign or malignant, poorly defined
not outlined in cortical bone
multilocular - RL
multiple compartments, soap bubbles
typically corticated borders
large, expansile
focal opacity - RO
well defined, localized
target lesion - RO
well defined, localized, RL halo
multifocal confluent - RO
multiple overlapping
irregular - RO
no defined pattern, hard to identify
ground glass - RO
pebbled, almost like an orange peel
mixed lucent-opaque - RO
radiolucent with radiopaque flex
soft tissue opacity - RO
well defined, localized where soft tissue should be
how do we detect periodontal disease
clinical examination and radiographs
localized
less than 30%
generalized
greater than 30%
severity of bone loss
mild: 1-2 mm
moderate: 3-4 mm
severe: >5 mm
what type of x-ray is recommended to identify pathology
paralleling technique
best way to see alveolar crest levels
vertical bitewings
fracture types
crown, root, jaw
luxation
displacement - partical
