COHIP

The Child Oral Health Impact Profile (COHIP) is a 34-item instrument measuring oral health-related quality of life in children and adolescents aged 6-14 years. Developed by Broder and colleagues and refined through the National Institute of Dental and Craniofacial Research (NIDCR), the COHIP captures developmental and age-appropriate impacts of oral conditions (caries, malocclusion, traumatic injury) on children's functional well-being, emotional state, and social participation. The COHIP is the paediatric equivalent of OHIP-14 and has become the standard measure for child-centred outcomes in paediatric dental research.
