Cleft lip and/or palate (CL/P) vs No cleft lip and/or palate (non-CL/P)

Early childhood caries experience (mean dmft) · Children in the primary dentition with non-syndromic cleft lip and/or palate (CL/P) and comparable children without CL/P

In the combined primary and mixed dentition, there was no evidence of a difference in caries experience between children with and without CL/P (SMD 0.09, 95% CI -0.59-0.76; 5 studies; ungraded).

  • Caries in children with and without orofacial clefting: A systematic review and meta-analysis. 2022 All outcomes
    Children with CL/P and comparable non-CL/P children across 12 countries (India, Brazil, China, Sweden, UK, USA, Germany, Greece, Ireland, Netherlands, Jordan, Thailand); studies published 1989-2021
    Five studies investigated caries experience by cleft type (Howe 2017; Kirchberg 2014; Mutarai 2008; Sunderji 2017; Zhu 2010). A subgroup analysis comparing CP and CL/P as different entities was not possible due to the…
