(Reading) Flashcards

Reading an occlusal cant on a frontal cephalogram or photograph, this finding most often relates to which type of asymmetry?

Answer: Transverse/vertical facial asymmetry

An occlusal cant reflects vertical-transverse facial asymmetry between the two sides.

In the ABO CR-Eval, the 'occlusal relationships' criterion deducts points for what?

Answer: Class discrepancies in molar/canine/premolar intercuspation

Point deductions occur when posterior teeth do not achieve proper Class I intercuspation.

When reading a cephalometric superimposition on the anterior cranial base (SN), the clinician evaluates what?

Answer: Overall facial growth and treatment changes

SN superimposition reveals overall growth changes and the net effect of treatment over time.

A radiograph shows a tooth with an inverted crown positioned high in the maxilla; this ectopic finding is termed what?

Answer: Impaction with inversion

An unerupted, inverted tooth high in the jaw is an inverted impaction.

In reading the interincisal angle on a cephalogram, a decreased (more acute) angle usually indicates what?

Answer: Proclined/protrusive incisors

A smaller interincisal angle corresponds to proclined, protrusive upper and lower incisors.

The ABO clinical examination emphasizes evidence-based reading of literature; a randomized controlled trial ranks where in the evidence hierarchy?

Answer: High, above case reports and cohort studies

Randomized controlled trials sit high in the hierarchy, above cohort studies and case reports.

When interpreting a TMJ tomogram or CBCT slice, condylar position is best described relative to which structure?

Answer: The glenoid fossa and articular eminence

Condylar position is assessed within the glenoid fossa relative to the articular eminence.
