Molar incisor hypomineralisation: experience and perceived challenges among dentists specialising in paediatric dentistry and a group of general dental practitioners in the UK

Eur Arch Paediatr Dent. 2016 Apr;17(2):81-8. doi: 10.1007/s40368-015-0209-5. Epub 2015 Nov 27.


Aim: To assess the views and experience of the UK dentists specialising in paediatric dentistry (trainees) about molar incisor hypomineralisation (MIH) and compare the findings with the responses from a group of UK general dental practitioners.

Method: A web-based questionnaire was sent to dentists undergoing specialist training in paediatric dentistry. The same questionnaire was completed by a group of general dentists who stated an interest in treating children, with various levels of experience. The questionnaire sought information on clinical experience and the views of the dentists on the impact of MIH on children and families.

Results: Specialty trainees (37) from different paediatric dental departments in the UK completed the online survey, giving a total response rate of 71%. The questionnaire was also completed by 31 general dental practitioners. There was difficulty in distinguishing MIH from other conditions for both groups. Increased sensitivity of affected teeth was the most frequently encountered problem with 51% of the trainees and 76% of the dentists saying this was often or always a challenge. The trainees were particularly concerned about the pain children experienced and about the appearance of the condition. Both groups felt that parental anxiety occurred in almost all cases.

Conclusions: Both groups felt that MIH presents several clinical challenges and has a negative effect on the quality of life of the affected children and their families. There were significant differences in the views and perceptions between the two groups.
