Introduction

Question 1

Differential Diagnosis
(4)

Answer 1

• Orderly sequential approach
• Gathering and analyzing data
• Knowledge and experience enable
  recognition of abnormal findings
• Include and/or exclude disease processes
  based on an educated assessment of the
  process

Question 2

Maxillary Premolar PA
(4)

Answer 2

• Receptor parallels B and Li planes of premolars
• Receptor parallels long axis of premolars
• Anterior edge of receptor includes distal ½ of canine, the premolars and some of molars
• Horizontal angle directed through distal of canine/premolar, premolar/premolar and the 2nd
  premolar/ molar contacts

Question 3

Maxillary Canine PA
(4)

Answer 3

• Receptor placed parallel to B
  and Li planes of canine
• Receptor parallels long axis
  of canine
• Canine is within middle two
  1/4s of mesiodistal width
• Horizontal angle directed
  through mesial contact of
  canine

Answer 5

• single vs multiple,
  (aka monostotic vs polyostotic [systemic])
  *location
• relative proximity to adjacent structures
  *size in dimensions
• outline - well-demarcated vs diffuse,
  corticated vs non corticated
• density : radiolucent, radiopaque or mixed
