In what direction are 50% of maxillary lateral teeth dilacerated?

Mesial
Distal
Buccal
Lingual

The correct answer is: Distal

Maxillary lateral teeth are most commonly dilacerated in a distal direction. This is due to the fact that during the development of the tooth, the distal portion of the tooth forms last. Any traumatic incident or pressure during this critical period can cause the tooth to bend or curve in a distal direction, resulting in dilaceration. This is why 50% of maxillary lateral teeth are dilacerated distally. Option A (Mesial) is incorrect because the distal portion of the tooth forms last, making it more susceptible to developmental disturbances leading to dilaceration. Option C (Buccal) is incorrect as the buccal aspect of the tooth is less likely to be affected by developmental disturbances causing dilaceration. Option D (Lingual) is incorrect because dilacerations typically occur in the external portion of the root structure, not towards the lingual aspect of the tooth.
