Can you detect a midline discrepancy?

According to a study published in the Journal of Esthetic Dentistry, which evaluated the perceptions among dentists, orthodontists, and lay people on a variety of esthetic discrepancies, a maxillary midline deviation of 4 mm was necessary before orthodontists rated it significantly less esthetic than the others. However, general dentists and lay people were unable to detect even a 4-mm midline deviation. Conversely, when the midline angulation deviated only 1mm, all three groups noticed. As a team, it is important that we pay particular attention to ensure the angulation of the midline is perpendicular.
