Self-Esteem and Oral Health-Related Quality of Life within a Cleft Lip and/or Palate Population: A Prospective Cohort Study

Abstract

(1) Objective: To investigate the oral health-related quality of life (OHRQoL) and self-esteem (SE) of a population with cleft lip and/or palate (CLP) and to compare it with a non-affected control cohort. (2) Materials and methods: This study comprised 91 CLP patients and a control group of 790 individuals, seeking orthodontic treatment. OHRQoL and SE were assessed by the Child's Perception Questionnaire (CPQ) and the Dutch adaptation of the Harter's Self-Perception Profile for Adolescents. Treatment need and self-perception of oral aesthetic were assessed using the Index of Orthodontic Treatment Need (IOTN) and the Oral Aesthetic Subjective Impact Scale (OASIS). Patients' expectations and motivation for treatment were also scored. Linear models were used for statistical comparisons between groups. (3) Results: The cleft group scored higher in all domains of the CPQ, OASIS, IOTN and regarding SE for the domains of scholastic competence, athletic competence, physical appearance and behavioral conduct. The cleft group was not only more motivated and expected less discomfort during treatment but also had higher expectations for the treatment outcome. (4) Conclusions: The OHRQoL of CLP patients is strongly correlated with the presence of an oral cleft, while SE remains a personal resource not influenced by the malocclusion or medical condition.
