What is the BEST method to assess Angle classification clinically?
Show answer and explanation
Correct answer: B. Intraoral lateral photograph
- A. Incorrect. An intraoral frontal view shows the anterior dentition and overbite/overjet but does not provide a direct view of the molar relationship needed for Angle classification.
- B. Correct. ANGLE'S CLASSIFICATION is assessed based on the relationship of the mesiobuccal cusp of the maxillary first molar to the mandibular first molar. The INTRAORAL LATERAL photograph (taken from the side, inside the mouth) directly shows the buccal molar relationship, making it the best clinical image for assessing Angle classification.
- C. Incorrect. An extraoral lateral photograph shows facial profile (skeletal relationships) but not the intraoral molar relationship specifically.
- D. Incorrect. An extraoral frontal photograph shows facial symmetry and frontal proportions — not the molar relationship.
