Identifying associations between dental arch relationship scores, relative deprivation and other cleft audit outcomes. Part 2.

Abstract

Identify associations between dental arch relationship scores, oral health status and deprivation index in patients with complete unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP). Ninety-two 5-year-old children with non-syndromic complete UCLP and thirty-nine 5-year-old children with non-syndromic complete BCLP from the United Kingdom. Data were collected from the 5-year audit outcomes submitted to the Cleft Registry and Audit Network (CRANE). The index of multiple deprivation (IMD) and Welsh index of deprivation were used to assess a relative measure of deprivation. Comparisons of 5-year-old index/BCLP Deciduous Dentition Yardstick outcome against IMD and dmft are performed using multivariable linear regression models. Both UCLP and BCLP had a high percentage of children with dmft >0 (47% and 49%, respectively). The mean dmft for the UCLP cohort was 2.8 and 2.6 for the BCLP cohort. In the UCLP group, a poorer 5-year-old index was associated with an increased dmft score (P=.023) and higher level of deprivation (P=.010). In the BCLP group, there was no significant associations between BCLP Deciduous Dentition Yardstick, dmft and IMD. A poorer dental arch relationship outcome may be associated with higher level of area deprivation and oral health status, in children with UCLP. Those with a poor outcome for the 5-year-old Index are more likely to have increased caries experience.
