Enamel defects on the maxillary premolars in patients with cleft lip and/or palate: a retrospective case-control study.

Aim The purpose of this study was to investigate the presence of developmental defects of enamel on maxillary premolars in patients with cleft lip and/or palate. In addition, the relationship with the surgical technique of soft palate closure was studied. Such a relationship could be suspected since formation of enamel occurs around the same time period as soft palate closure.
