The caries develops in both the crowns and roots of teeth. Progress of caries depended on the lifestyle of the child (as high numbers of cariogenic bacteria, inadequate salivary flow, insufficient fluoride exposure and poor oral hygiene). To avoid this disease should follow the proper oral hygiene and improve lifestyle . A lot of methods found to treatment the decayed tooth - like; Hall technique and Silver diamine fluoride The first report on the Hall Technique published in 2007 by a general dental practitioner from Aberdeen/Scotland, Dr. Norna Hall. Dr. Hall used PMCs to restore carious primary molars rather than using the standard technique, placed them using a simplified method2\n\nPrevious studies have recommended that Silver diamine fluoride (SDF) solution would exert a preventive result in managing early childhood caries ECC.
