Case Study – Molar Incisor Hypomineralisation or (MIH)
A 7 year old child presented with a decayed lower molar tooth.
Mum was concerned as the patient was experiencing severe sensitivity and could not eat on the tooth. After the teeth were examined it was established that the tooth was not decayed but hypomineralised. The condition is known as Molar Incisor Hypomineralisation or (MIH). As the name suggests, this condition can affect the molars (the back teeth) and, or the incisors (the front teeth).
It most commonly affects the Molars and more commonly the first permanent molar teeth, which appear in the mouth typically between 5 and 7 years of age.
Hypomineralisation means that the enamel or the tough outer layer of the tooth is hypo or under mineralised, which essentially means not properly formed and is in fact quite soft. Local anesthetic was administered because of the sensitivity, the rubber dam placed and the soft enamel was removed . The tooth restored and fissure sealed. There was in fact no tooth decay present.
At review the sensitivity had resolved and the patient was eating comfortably on the tooth. This intervention has dramatically reduced the risk of tooth decay.
