Introduction: Hall technique (HT) is a biological approach where decay is sealed under preformed metal crowns without any caries removal, tooth preparation or local anesthesia. Dental caries is one of the most common prevailing chronic condition that affect both adults and children. Since children are anxious and apprehensive to dental treatment, their uncooperative behavior might cause hindrance in the treatment, which often leads to manage them in general anesthesia. To better address the dental care needs in pediatric patients, dental surgeons require some alternatives for management of caries and restorative treatment in children. The Hall technique is one such conservative treatment approach developed by Dr Norna Hall in 1980s. Aim: The purpose of this study was to assess the clinical effectiveness and patient acceptance of Hall technique for managing carious primary molars. Materials and methods: 84 children in the age group 6–10 years with class I and class II carious lesions limited to dentin were selected for the study. Occlusal vertical dimension (OVD) was measured preoperatively, postoperatively and after 6 months. Discomfort level was assessed by facial pain rating scale and by questionnaires filled on the day of placement of SS crown, 1 week after placement and 6 months after placement. Results: The Hall technique was found to be successful, as there was no failure clinically as well as radiographically within 6 months of placement of SS crown. The increased OVD postoperatively returned to its normal values within 6 months, the mean change in the OVD was found to be statistically significant (p = 0.02). Conclusion: The Hall technique proved to be clinically effective and acceptable by maximum number of children.
