Comparison of aesthetic treatments for molar-incisor hypomineralisation: Systematic review and meta-analysis.

Introduction: Molar incisor hypomineralisation (MIH) is a developmental defect that predominantly targets the first permanent molars and incisors and consists of hypomineralisation of the enamel. A range of treatment options are available to improve aesthetics in this condition, including resin infiltration, bleaching techniques, restorations, microabrasion, and laser therapy. Objectives: This systematic review and meta-analysis aimed to analyse the effects of treatments on changes in enamel colour in teeth with MIH lesions and determine whether resin infiltration is the most aesthetic treatment. Material and Methods: A systematic literature search was conducted on PubMed, Web of Science, EBSCO, and Scopus databases until December 2022. The addressed PICO question was: "Is resin Infiltration the most effective treatment for restoring aesthetics in comparison to other treatments in patients with Molar incisor hypomineralisation?''. In addition, a meta-analysis was conducted with the selected studies to integrate the information using R.51 software (R Core Team (2013)). Results: In total, 678 articles were obtained from the initial search, of which 11 met the inclusion criteria. Seven studies concluded that resin infiltration was the most successful treatment method in the aesthetic rehabilitation of MIH lesions. Six of the eleven articles were included in the meta-analysis, which indicated that the treatments generated substantial colour changes. Conclusions: This systematic review and meta-analysis provided significant data suggesting that resin infiltration is the most effective treatment for achieving aesthetic improvements in MIH lesions, with the meta-analysis providing a significant result (p = 0.051) in favour of the hypothesis.

A new model to deliver scheduled outpatient care.

Here we describe an integrated model for scheduled care (the 'cluster clinic'). Following a pilot in April 2018, cluster clinics were established across Aberdeen City from April 2019 but not the area surrounding Aberdeen (ie, Aberdeenshire). There were 2360 referrals in 2017/2018 (pre-cluster clinic), and 2615 in 2019/2020 (post-Aberdeen City cluster clinics). The proportions of referrals from City practices seen pre-cluster and post-cluster were 72% and 56%, respectively, and from Shire practices the corresponding proportions were 70% and 65%. The cluster clinic received positive feedback from parents and referring clinicians and was not associated with increased 'missed diagnoses' compared with business as usual clinic. The cluster clinic model is a realistic and effective method to deliver integrated scheduled care for children.
