LEUVEN, Belgium: The prevalence of molar incisor hypomineralisation (MIH) in paediatric patients around the world is currently estimated at about 13%. Yet, the precise aetiology of the disease is still largely unknown. The current armamentarium has its limits, and knowledge . Recently, a group of experienced specialists gathered at the GC Europe campus in Belgium to kick off a long-term collaboration to unravel the conundrum that MIH has become.
During the meeting, which was chaired by Dr Norbert Krämer, a professor for paediatric dentistry at Justus Liebig University Giessen in Germany, the experts discussed all aspects of this developmental dental disease, including pain and hypersensitivity control, emergency treatments and solutions, and short- and long-term treatments. The conclusion reached was that products based on casein phosphopeptide-amorphous calcium phosphate play a key role in tackling the associated hypersensitivity and remineralisation. In addition, the participants agreed that glass ionomers and stainless-steel crowns are much valued tools in emergency and short-term treatments, whereas glass hybrids, composites and several types of indirect restorations are suitable for longer-term care.
A recent systematic review, published in November 2021 in Scientific Reports, that included 116 MIH studies, involving a total of 135,181 participants from 50 different countries, showed that the overall prevalence of MIH was 13.5%. The researchers reported that over one-third (36.6%) of participants had MIH-affected incisors and 3.6% had hypomineralisation-affected primary second molars.
MIH impacts the quality of life of many children, as they have to deal with chronic pain, hypersensitivity, aesthetic problems and frequent visits to the dentist. All participants in the network meeting confirmed that, despite much interest in this topic from researchers, practitioners, and patients and their parents, there is still insufficient knowledge about the disease. The aetiology seems to be complex and the clinical appearance shows broad variation, making this phenomenon very difficult to study.
In order to improve the understanding of MIH among the dental community as well as the public and to develop new treatment solutions adapted to patients with MIH, further high-quality research on large study group is needed. The aim of the MIH network collaboration is to study a large, widespread and representative population in a standardised way.
GC Europe has always taken much interest in this particular topic and is an active participant in developing MIH treatment solutions. The company provides valuable information about products and treatment plans as well as educational videos and webinars at campaigns-gceurope.com/mih.
