Analyse de la densité minérale de dents temporaires atteintes d’hypominéralisation (DMH)

Abstract : Molar-Incisive hypomineralizations (MIH) are qualitative abnormalities of the enamel affecting 1 to 4 permanent first molars and possibly permanent incisors. In 2003, Weerheijm claimed that these defects could also be found on the enamel of the second temporary molars, then known as Hypomineralized Second Primary Molars (HSPM) or Deciduous Molars Hypomineralization (DMH). Several studies conducted on the enamel of molars with MIH showed that the latter presented a significant decrease in mineral density compared to the enamel of a healthy tooth, thus explaining its low resistance. However, in the literature we find only one study to this day that has looked at the analysis of the mineral density of DMH teeth and no studies have attempted to compare these data with those found on MIH teeth. The objective of this thesis was therefore to study the mineral density of the enamel of temporary teeth with DMH and to compare it with the mineral density of permanent teeth with MIH. To do so, second healthy temporary molars and second temporary molars with DMH as well as first permanent molars with MIH were extracted with the prior consent of children and parents. They were X-rayed using a micro-CT and the resulting images were analyzed with the Image J software following a protocol that will be detailed in this thesis.
