Retrospective evaluation of treatment outcome in Japanese children with complete unilateral cleft lip and palate. Part 1: Five-year-olds' index for dental arch relationships.
OBJECTIVE
To evaluate the dental arch relationships of Japanese children with complete unilateral cleft lip and palate (UCLP) and to examine the 5-year-olds' index for its validity.


METHODS
Retrospective study and comparison with previous reports.


METHODS
One hundred thirty-six children with complete UCLP who received primary cheiloplasty and palatoplasty in the Kyushu University Hospital from 1966 to 1999.


METHODS
Dental models taken from children 53 to 67 months of age and their cephalograms.


METHODS
Study models were assessed using five scores; 1=excellent, 2=good, 3=fair, 4=poor, and 5=very poor, in accordance with the 5-year-olds' index and also evaluated using Huddart and Bodenham's numerical classification. Dental arch widths, three-dimensional maxillary dental arch form, and lateral cephalograms were traced and measured. The outcome by 5-year-olds' index was compared with Huddart and Bodenham's numerical classification, dental arch dimensions, and cephalometric measurements.


RESULTS
Occlusal outcome evaluated by the 5-year-olds' index was rated 2.95, which was classified as fair. This index rating showed a significant relationship with numerical classification and dental arch length, but not with dental arch width. The index showed a relationship with mandibular form and position, but not with maxillary position.


CONCLUSIONS
The occlusal outcome of the cases with UCLP was fair as evaluated using the 5-year-olds' index. The index evaluates the anteroposterior relationship of maxillary/mandibular dental arches but does not evaluate the collapse of maxillary segments.
