Molar incisor hypomineralisation (MIH) is a common enamel condition, presenting with incisor opacities, which may be of psychosocial concern to children. This clinical study sought to determine whether minimally invasive treatment, aiming to improve incisor aesthetics, would also improve children’s oral health-related quality of life (OHRQoL). 111 MIH patients, aged 7–16 years, referred to a UK Dental Hospital, were invited to complete the Child Oral Health Impact Profile (C-OHIP-SF19) prior to any intervention (T0) and again at one-month following the intervention (T1) for MIH. Treatment regimens included one or more of the following: Microabrasion; resin infiltration; tooth whitening; resin composite restoration. Data were obtained for 93 children with a mean age of 11 years. Mean total C-OHIP-SF19 score at T0 was 47.00 (SD = 9.29; range = 0–76) and this increased significantly at T1 to 58.24 (SD = 9.42; range = 0–76; p < 0.001, paired t-test), indicating a marked improvement in self-reported OHRQoL. There were no statistically significant differences according to gender. This is the first study to show that simple, minimally invasive dental treatment, to reduce the visibility of enamel opacities, in MIH, can have a positive impact on children’s wellbeing.

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

This article aims to provide general dental practitioners (GDP) with the knowledge to improve their referrals primarily for children who they feel require a dental general anaesthetic. It discusses the impact of a general anaesthetic (GA) on a child and the financial impacts of dental general anaesthetics (DGA). The risks of DGA are well recognised and the ways in which the dental team in primary, secondary care and service commissioners can reduce the risk of repeat DGA are discussed.Clinical relevance statement: Dentists should be aware of the risks involved in GA and the importance of reducing repeat DGA.Objective statement: To reduce repeat DGA, dentists should ensure the referral process and assessment prior to DGA is optimal.

Background: Clinical observations suggest molar incisor hypomineralisation (MIH)may present with other dental conditions. Aims: The study aimed to determine the prevalence and variety of dental anomalies in children presenting with MIH. Design: A convenience sample of children referred to a UK dental hospital was recruited. Orthopantogram radiographs, taken as part of routine care, were assessed for dental anomalies. Two calibrated examiners reviewed the films separately and determined the presence and character of anomalies. Results: Radiographs were obtained from 101 patients, with an age range of 6-15 years. Co-existing hypodontia was identified in 12%, with lower second premolars being the most commonly missing teeth. Concurrent ectopic first permanent molars were identified in 8%, and infraocclusion of one or more primary molars was identified in 9%. Abnormal morphology was found in 9%, including macrodont and microdont teeth. In total, 29% of patients had an associated dental anomaly.Examiners had perfect agreement using Cohen's kappa coefficient. Conclusion: This high prevalence of dental anomalies, particularly hypodontia, in children with MIH is a novel and clinically important finding. Further research is warranted considering the potential implications for assessment and treatment planning. K E Y W O R D Sdental anomalies, hypodontia, molar incisor hypomineralisation
