Parallel |technique |is |used |to |radiograph |which |set |of |teeth? |- |CORRECT |ANSWER✔✔-Posterior
|mandible |teeth |and |nasal |cavity
Parallel |technique |- |CORRECT |ANSWER✔✔--sensor |is |placed |parallel |to |the |structure |being |
radiographers. |
-The |sensor |is |inserted |between |the |tongue |and |mandible
Bisecting |angle |technique |- |CORRECT |ANSWER✔✔--Used |in |areas |where |the |parallel |
technique |cannot |be |used
-obtained |by |visualizing |an |imaginary |line |that |bisects |the |angle |formed |by |the |x-day |dim |and |
structure |being |radiographed
Elongation |can |occur: |- |CORRECT |ANSWER✔✔-When |the |cone |head |was |aimed |at |the |tooth |
as |opposed |to |the |bisecting |angle |between |the |tooth |and |the |film
Foreshortening |can |occur: |- |CORRECT |ANSWER✔✔-When |the |cone |head |may |have |been |
aimed |too |directly |at |the |film, |opposed |to |the |bisecting |angle
The |bisecting |angle |technique |states |that |the |plane |of |an |x-ray |beam |should |be |90 |degrees |to |
the? |- |CORRECT |ANSWER✔✔-Imaginary |line |that |bisects |the |angle |formed |by |the |tooth's |long |
axis |and |the |film |plane
In |a |young |patient, |the |dentinal |wall |is |______, |and |in |an |older |patient |it |is |______. |- |
CORRECT |ANSWER✔✔-Thin, |thick
, Lamina |dura |is: |- |CORRECT |ANSWER✔✔-Referring |to |the |dense |cortical |bone |forming |the |wall |
of |the |alveolus
Lamina |Lucida |- |CORRECT |ANSWER✔✔-The |radiolucent |image |between |the |lamina |dura |and |
tooth |is |the |periodontal |space |and |occupied |by |the |periodontal |ligament.
In |radiographs, |an |apical |abscess |appears |as |a? |- |CORRECT |ANSWER✔✔-Radiolucent |area |
around |the |apex |of |the |tooth
An |impacted |tooth |is |defined |as: |- |CORRECT |ANSWER✔✔-An |unerupted |or |partially |erupted |
tooth |that |is |prevented |from |erupting |further |by |any |structure
Dilaceration |is: |- |CORRECT |ANSWER✔✔-An |abnormally |shaped |root
What |is |the |radiologic |term |for |a |periapical |abscess |in |a |radiograph? |- |CORRECT |ANSWER✔✔-
Periapical |lucency
Edentulous |- |CORRECT |ANSWER✔✔-A |sense |of |teeth
Embedded |tooth |- |CORRECT |ANSWER✔✔-A |tooth |that |is |usually |covered |in |bone, |has |not |
erupted |into |the |oral |cavity, |and |is |not |likely |to |erupt
Dental |radiographs |are |indicated |- |CORRECT |ANSWER✔✔--Before |extractions |for |diagnosis, |
evaluation |and |possible |complications. |
-during |the |procedure |to |determine |the |presence |of |retained |roots |and |other |complications
-after |yo |ensure |completeness |of |procedure
