To compare dental arch relationships up to age 17 in individuals with complete unilateral cleft lip and palate (UCLP) treated at five European centers.
Design
Longitudinal cohort study, where results were previously reported at 9 years and follow-up measurements were obtained for 12 and 17 years.
Setting
Multidisciplinary cleft services in Northern Europe.
Subjects
127 consecutively treated individuals with repaired UCLP.
Main outcome measure
Panel rating of dental arch relationship.
Results
The results revealed that at 17 years of age three of the centers had better ratings in dental arch relationship (means scores: 1.7, 1.9, and 2.2, respectively) than the other two centers (3.3, 3.4) at statistically significant levels (p < .01 to p < .001).
Conclusion
The results confirm that systematic differences in dental arch relationships may occur between different cleft centers, but do not allow specific causal factors to be identified.
