Treatment Outcome of Bangladeshi UCLP Patients Based on Both Phenotype and Postnatal Treatment Factors using Modified Huddart Bodenham (mHB) Index

Abstract

Objective:

To evaluate the dental arch relationship (DAR) of nonsyndromic unilateral cleft lip and palate (UCLP) and to explore the various phenotype and postnatal treatment factors that are responsible for poor DAR.

Design:

Retrospective study.

Setting:

School of Dental Science, Universiti Sains Malaysia.

Subjects:

Eighty-four Bangladeshi children with nonsyndromic UCLP who received cheiloplasty and palatoplasty.

Main Outcome Measures:

Dental models were taken at 5 to 12 years of age (man: 7.69), and dental arch relationships were assessed using modified Huddart/Bodenham index (mHB) by two raters. Kappa statistics was used to evaluate the intra- and interexaminer agreements, chi-square was used to assess the associations, and logistic regression analysis was used to explore the responsible factors that affect DAR.

Results:

The total mHB score (mean [SD]) was −8.261 (7.115). Intra- and interagreement was very good. Using crude and stepwise backward regression analysis, significant association was found between positive history of class III (P = .025, P = .030, respectively) and unfavorable DAR. Complete UCLP (P = .003) was also significantly correlated with unfavorable DAR.

Conclusion:

This multivariate study suggested complete type of UCLP and positive history of class III had a significantly unfavorable effect on the DAR.
