[Child-friendly restorations of primary molars using the Hall technique].

Minimally invasive dentistry is being used increasingly often, especially in paediatric dentistry. It involves replacing traditional 'drilling and filling' with treatment modalities that are tissue-saving and minimally burdensome to the patient. One of these techniques for treating carious dentine lesions is the Hall technique. A stainless-steel crown is cemented onto the primary molar without the use of anaesthesia or any form of preparation. The molar is 'sealed' under the crown and this stops the carious process in the cavity. Usually, the procedure requires 2 sessions. The Hall technique is well tolerated by children and provides the primary molar with a durable restoration. Together with this technique, the patient is also guided in an individual prevention process. The survival rates of Hall crowns are very high.
