As the dentistry is having the shift from extension for prevention to prevention of extention, it is also a moving from drilling to no drill concept. Hall’s technique is a non-invasive treatment for carious primary tooth. The concept recommended the use of Stainless steel crown. This technique does not involve administration of local anesthesia, no rubber dam application and no drilling. In essence there was no dental caries removal at all from the carious lesion. The technique relied on sealing the carious lesion in situ cutting off its supply of sugary substrate, thus altering the bacterial plaque of the lesion ultimately leading to the arrest of the caries process in the tooth. Hence, this presentation will throw the light on the detailed description of Hall’s technique in pediatric dentistry.
