The long axis of the maxillary first molar is inclined to:
- A- Buccal.
- B- Mesial.
- C- Distal.
- D- Lingual.
The long axis of the maxillary first molar is inclined to: (A. Buccal).
This means that the tooth leans slightly outwards towards the cheek when viewed from the front of the face. This inclination contributes to the natural curvature of the dental arch and the proper occlusion of the upper and lower teeth.
Other Options:
Here's why the other options are incorrect:
- Mesial:
This refers to the direction towards the midline of the face, but the maxillary first molar's long axis doesn't have a significant inclination in this direction.
- Distal:
This refers to the direction away from the midline of the face, also not a significant inclination for the maxillary first molar's long axis.
- Lingual:
This refers to the tongue side of the tooth, which is the opposite direction of the buccal inclination.
Therefore, the buccal inclination of the maxillary first molar is the most accurate answer.
