Abstract
Aim: To investigate the interdental arch relationship outcomes of 5-year-old children withunilateral cleft lip and palate (UCLP) before and after centralisation of cleft services in the
United Kingdom (UK) using the Modified Huddart-Bodenham Index (MHBI).
Design: Retrospective cross-sectional study.
Setting: Evaluation of 3D orthodontic study models of children with a complete UCLP.
Participants: All available 5-year-old orthodontic study models of participants with UCLP from
the pre-centralisation (Clinical Standard Advisory Group CSAG n=107) and post-centralisation
(Cleft Care UK CCUK n=195) studies.
Outcome measure: Differences between the interdental arch relationship outcomes for the
CSAG and CCUK cohorts were assessed using the Modified Huddart-Bodenham Index (MHBI).
This index scored the buccal/palatal or labial/palatal relationships of 8 maxillary deciduous
teeth with the opposing mandibular dentition. The anterior segment (deciduous central
incisors), buccal (deciduous canine, first and second deciduous molar) cleft segment and noncleft segment scores were calculated along with the sum of the three segments combined to
calculate the total arch MHBI scores.
Results: The inter- and intra-examiner reliability had a high level of agreement. Statistically
significant differences in the anterior segment, buccal non cleft segment, and total arch MHBI
3
scores were found between CCUK and CSAG cohorts, with CCUK performing better. There was
no difference in the buccal cleft segment scores.
Conclusions: There were improved transverse and anterior interdental arch relationships
post centralisation (CCUK) of cleft services in the UK, suggestive of better primary surgical
outcomes post CSAG.
