# Evaluating Dental Arch Relationships in Indonesian Patients with Operated Bilateral Cleft Lip and Palate Using Modified Huddart/Bodenham Index and Bauru-bilateral cleft lip and palate (BCLP) Yardstick

## TL;DR

This study evaluates dental arch relationships in Indonesian children with operated bilateral cleft lip and palate using specific assessment tools.

## Contribution

The study demonstrates the effectiveness of the modified Huddart/Bodenham index and Bauru-BCLP yardstick in assessing dental arch relationships in operated CBCLP patients.

## Key findings

- Patients with operated CBCLP showed edge-to-edge tooth relations categorized as mild crossbite or deviation.
- Orthodontic treatment was deemed necessary based on the assessments.
- The CLP repair protocol at Harapan Kita Hospital yielded satisfactory results.

## Abstract

Patients with complete bilateral cleft lip and palate (CBCLP) have the most complex orofacial abnormalities despite its lowest incidence among cleft lip and palate (CLP) types. Impaired maxillary growth can result from surgical procedures in patients with CBCLP. This study evaluates dental arch relationships in Indonesian patients with CBCLP after undergoing CLP repair at Harapan Kita Children and Mother Hospital in Jakarta.

Using the modified Huddart and Bodenham (MHB) index and Bauru bilateral cleft lip and palate (BCLP) yardstick, three examiners assessed 17 study models in the 9-year age group and 13 study models in the 12-year age group, as well as two intraoral clinical photographs of two patients with CBCLP. The assessments were repeated three times within two weeks of each assessment time.

Patients with operated CBCLP (aged 9 and 12 years) had edge-to-edge tooth relations, which were categorized as a mild crossbite or mild deviation, and only required orthodontic treatment according to the two specified indicators.

The CLP repair protocol used at the Harapan Kita Hospital effectively manages CBCLP cases with satisfactory results, suggesting the effectiveness of the MHB index and Bauru-BCLP yardstick in assessing dental arch relationships in patients with operated CBCLP.
