The figures are alarming. According to the latest estimates,
between 10 and 15% of children in France are affected by hypomineralization of molars and incisors, or MIH (Molar-Incisor Hypomineralization in English)explain
The Parisian. A proportion which could even be underestimated and rise to one child in four affected. The disease causes fragility of the enamel and manifests itself as spots, ranging from white to brown. It can also lead to significant damage to the teeth. But what is MIH and what are its consequences?
Identified in the early 2000s, MIH remains an enigma for scientists. The exact causes of the disease are still unknown, but suspicion is increasingly focused on theendocrine disruptorsthese chemicals present in our environment that can interfere with our hormonal system. Bisphenol A, widely used in the manufacture of plastics, is particularly singled out. “The MIH is an indicator of environmental pollution“, affirmed Vianney Descroix, professor at the faculty of dental surgery at the University of Paris. Because to realize the danger represented by MIH, we must know the evolution of our dentition. However, tooth enamel is formed during pregnancy, a period when the fetus is particularly vulnerable to external aggression. Endocrine disruptors could thus alter the formation of enamel and make it more fragile.
Can MIH be treated?
Unfortunately, there is currently no cure for MIH. Care mainly focuses on
prevention of cavities and restoration of damaged teeth. Fluoride varnishes, resins, fillings… dentists have several tools at their disposal to strengthen enamel and protect teeth.
However, living with MIH remains a challenge for people with this disease. Affected teeth are more sensitive to heat, cold and acidic foods. Caries are more frequent, and treatments more complex. “There is no cure“, underlines Christophe Lequart, vice-president of the French Union for Oral Health.
Prevention as the key to fighting MIH
Despite the fact that MIH is a complex disease, prevention remains the best weapon. Good oral hygiene, a balanced diet and regular visits to the dentist are the keys to limiting the damage. Parents of children with MIH should be particularly vigilant. Regular tooth brushing, use of fluoridated toothpastes and limiting sugary foods are essential.
Nevertheless, MIH is a disease that causes increasing concern. Although the causes are not yet fully understood, scientists agree that our environment plays an important role in its progress. Faced with this threat, dental and environmental prevention is more relevant than ever.
