Determinants of children’s oral health-related quality of life following aesthetic treatment of enamel opacities

Abstract

ObjectivesTo identify clinical and psychosocial predictors of oral health-related quality of life (OHRQoL) in children with molar incisor hypomineralisation (MIH) following aesthetic treatment of incisor opacities. MethodsParticipants were 7- to 16-year-old children referred to a UK Dental Hospital for management of incisor opacities. Prior to treatment (To), participants completed validated questionnaires to assess OHRQoL and overall health status (C−OHIP-SF19), and self-concept (Harter’s Self-Perception Profile for Children [SPPC]). Interventions for MIH included microabrasion, resin infiltration, tooth whitening or composite resin restoration. Children were reviewed after six months (T1) when they re-completed the C−OHIP-SF19 and SPPC questionnaires. The relationships of predictors with improvement of children’s OHRQoL (T1-To) and children’s overall health status at T1 were assessed using linear and ordinal logistic regression respectively, guided by the Wilson and Cleary’s theoretical model. ResultsOf 103 participants, 86 were reviewed at T1 (83.5 % completion rate). Their mean age was 11-years (range = 7−16) and 60 % were female. Total and domain OHRQoL scores significantly increased (improved OHRQoL) following MIH treatment. There was a significant positive change in SPPC physical appearance subscale score between To and T1. A higher number of anterior teeth requiring aesthetic treatment were associated with poor improvement of socio-emotional wellbeing at T1 (Coef =-0.43). Higher self-concept at To was associated with greater improvement of socio-emotional wellbeing at T1 (ß = 3.44). Greater orthodontic treatment need (i.e. higher IOTN-AC score) at T0 was linked to worse overall oral health at T1 (OR = 0.43). ConclusionsPsychosocial factors and dental clinical characteristics were associated with change in children’s OHRQoL following minimal interventions for incisor opacities. Clinical significanceMIH is a common condition and clinicians should be aware of the negative impacts some children experience, particularly those with multiple anterior opacities, poor tooth alignment and low self-concept. However, simple, minimally invasive treatments can provide good clinical and psychosocial outcomes and should be offered to children reporting negative effects.
