Dental Radiographs - Coggle Diagram
Dental Radiographs
techniques
mandibular
parallel
mandibular molars
performed in dorsal recumbency
bisecting angle
everywhere that sensor cannot be placed paralel
increasing horizontal angle "splits" the roots
SLOB rule
same lingual, opposite buccal
the root in the same direction as tube head is the lingual root
maxillary
performed in sternal recumbency
bone will appear slightly less dense than mandibular
mounted as if looking at the patient from the front/side
steps for evaluating pathology
periodontal disease?
bone loss
alveolar bone should be within 1-2mm of CEJ
horizontal?
vertical?
described as PD1-4
evidence of endodontic (dentin, pulp) disease?
dental trauma
abrasion
attrition
concussion
pulpitis
reversible
presence of tertiary dentin
pulp is vital
irreversible
pulp necrosis
failure to narrow
periapical lucency
internal resorption (rare)
tooth resorption?
loss of hard material of tooth
presentations
missing crown material
replacement of tooth root with bone
:cat:
idiopathic
starts externally
classified based on presence/absence of PDL
type 1
normal root opacity
normal PDL
type 2
loss of PDL
decreaed radiopacity of crown or root
type 3
1 normal root, one lost PDL root
:dog:
external
surface resorption
usually due to minor injury
PDL moving with root defect
external replacement resorption
loss of PDL
root replaced with bone
inflammatory resorption
cervical root surface resorption
idiopathic
starts at CEJ
internal
secondary to pulpitis
"apple core" appearance
other abnormalities?
developmental abnormalities
extra roots
dilaerated roots
retained deciduous teeth
cysts
tumors
lag behind clinical abnormalities
