Three groups of periodontally healthy young males, classified as to orthodontic status, were evaluated for proximal contact and marginal ridge relationships in the maxillary left quadrant. The majority of anterior teeth did not have satisfactory proximal contacts on both the mesial and distal aspects. Open or defective proximal contact relationships were common in all three orthodontic groupings. In posterior areas, the orthodontically treated group had the highest percentage of open contacts. The orthodontically treated group had a significantly higher percentage of even marginal ridges in the teeth that are customarily banded.
