Effect of maternal and early childhood illness on molar incisor hypomineralisation

ABSTRACT

The aim of the study was to investigate the effect of the medical status of the mother and the child during the period of first molar- incisor formation and development of hypomineralisation of these teeth. The mothers of all patients who attended the pediatric dentistry department of Prince Hashim bin Al Hussein Hospital from April 2008 to January 2009 and who were diagnosed to have molar- incisor hypomineralisation [MIH] were asked to fill a questionnaire about the medical status of themselves or that of their children postnatal. The sample consists of50 mothers and their 50 children, 32 females and 18 males between the ages of 7 and 13 years. The questionnaire composed of questions about prenatal, perinataly and postnatal illness. 18 [36%] of the mothers were suffering from medical problems prenatal and 6 [12%] had perinatal illness, 30 [60%] children have been subjected to disease postnatal, and 26 [52%] of the mothers and 20 [40%] of the children did not suffer from any medical problem. Several etiological factors can cause enamel defects and their occurrence may be related to prenatal or postnatal illnesses. It was found that there was a relationship between children with repeated illnesses in the first year of their life and prevalence of hypomineralisation defects on molars and incisors
