Perception of molar-incisor hypomineralisation (MIH) by Iraqi dental academics

Int J Paediatr Dent. 2011 Jul;21(4):261-70. doi: 10.1111/j.1365-263X.2011.01118.x. Epub 2011 Feb 20.


Background: The understanding and detection of molar-incisor hypomineralisation (MIH) is linked to its recognition by clinicians. No study has investigated dental clinicians' level of perception regarding MIH in the Middle East region including Iraq.

Aim: To determine the perception of Iraqi academic clinicians about MIH prevalence, severity and aetiological factors.

Design: A questionnaire, based on previous European and Australian/New Zealand studies was administered to the academic dental staff of Mosul University.

Results: A response rate of 77.7% was reported. General dental practitioners represented 30.8% of the total respondents, whilst 65.1% were dentists with post-graduate qualification. The majority of the respondents (81.2%) encountered MIH in their clinical activities and 37.3% of them identified that the prevalence appeared to have increased in recent years. Fewer than half of the respondents observed MIH affected teeth on a monthly basis. The condition was less commonly seen in primary second molars than the first permanent molars. A variation in views was recorded about MIH specific aetiological factor/s. Respondents advocated the need for clinical training regarding MIH-aetiological and therapeutic fields.

Conclusions: Molar-incisor hypomineralisation is a condition commonly diagnosed by Iraqi dental academics. No apparent consensus existed between the general and specialist dentists regarding the anticipated prevalence, severity and aetiology of this condition.
