Abstract A prevalent developmental defect of enamel, 'Molar incisor hypomineralisation (MIH) affects the first permanent molars and often the incisors in around 1 in 8 people worldwide, with some significant regional variation in prevalence. The defect affects the enamel, with decreased mineral density, strength and altered appearance – with great variability between and within individuals. Affected individuals, especially those with severely affected molars, have a considerable burden of care related to the affected teeth, and the outcomes of dental care are often poor. A similar condition affects the second primary molars, but evidence would suggest all teeth are susceptible to similar defects. From the paediatric dentists viewpoint, the provision of care can also be challenging, with difficulty of obtaining effective anaesthesia, especially in severe cases, decreased resin bond strengths and frequent failure of restorative interventions complicating treatment for the patient and the dentist. From the orthodontic viewpoint, early diagnosis on MIH, especially the severe form forces decision making on whether to maintain or extract severely affected teeth, and issues around timing, patient compliance, and asymmetric presentation of severity amongst the first permanent molars can complicate decision making. Therefore a strong relationship needs to exist between the orthodontist and the dentist. These issues will be discussed, as well as an update on recent research. Short Speaker Bio Professor David Manton has spent nearly 40 years in private practice and academia and is currently a Professor of Paediatric Dentistry at the UMCG, University of Groningen and at ACTA in Amsterdam. He previously convened the specialist training program in paediatric dentistry at the University of Melbourne, and was chair of the postgraduate education and research committee. David is involved in several collaborative and postgraduate research projects in both paediatric dentistry and orthodontics. Graduated BDSc (Melb) in 1984 and worked in general practice until 1991 when he undertook an MDSc in Paediatric Dentistry. He was dental advisor to the Australian Federal Government from 1994 – 1996 and won the KG Sutherland Prize of the Royal Australasian College of Dental Surgeons in 2007. He is an associate editor of Caries Research and a long term member of the editorial boards of the European Archives of Paediatric Dentistry and the International Journal of Paediatric Dentistry, and will become the EAPD editor in chief in the next month. David is a past president of the IADR paediatric oral health research group. Over the past 20 years David has spoken throughout Australia, Asia and Europe and has wide ranging research experience in Minimum Intervention Dentistry, caries remineralisation, especially CPP-ACP, the detection of carious lesions, developmental defects of enamel (especially MIH), resin infiltration of MIH lesions, and the use of calcium silicates in endodontics. He has published more than 180 manuscripts in peer-reviewed journals and according to Google scholar he has been cited over 10,000 times since 2019. He is currently supervising far too many PhD and masters student research projects. References Estivals J, Fahd C, Baillet J, Rouas P, Manton DJ, Garot E.
