Hall Technique Crown for Amelogenesis Imperfecta in Primary Molars: A Case Report

Amelogenesis Imperfecta (AI) is a rare genetic disease that affects the structure and appearance of the enamel. The etiology of AI can be various such as genetic, vitamin deficiency, local infection caused by trauma, birth defects, or idiopathic factors. Due to the fact that AI patients have thin layer of enamel, the treatment should cover all the surface and not alter or reduce the enamel structures. To cover all the teeth surface, preformed metal crowns (PMC) can be done by the technique called Hall technique. It is a method for managing primary molar with caries or other defects where the tooth is sealed under PMC without local anaesthesia, tooth preparation, and caries removal. An 8-year-old girl came to our attention showing yellowish teeth with rough surface, very sensitive to both cold and warm temperature on both upper and lower dentition. It was diagnosed as Amelogenesis Imperfecta. A complete treatment plan was carried.
