| Hall Technique (HT) | Device | Prior to each restoration, a bacterial sample of the lesion will be obtained with a cotton swap and dispensed in a transport medium for microbial analyses.The preformed metal crown (PMC) will placed without local anesthetic and without crimping or trimming. When the contact points are tight, an orthodontic elastic separator will be placed for 2 hours prior to PMC placement. The PMCs will be cemented with glass ionomer Ketac cem. |

| Amount of time taken to complete the intervention | from start of intervention to end of intervention (about 45 minutes to 11/2 hours) |
| Measure | Description | Time Frame |
|---|---|---|
| Number of participants with occlusal contact of the molars as assessed by the strip test | Measured by passing a strip between the contra-lateral upper and lower posterior natural teeth with the child biting into maximum intercuspation. If the strip passes without resistance between teeth anterior or posterior to the SSC there is no occlusal contact. | 3 months post intervention |

| Modified Hall Technique (MHT) | Device | Prior to each restoration, a bacterial sample of the lesion will be obtained with a cotton swab and dispensed in a transport medium for microbial analyses.This group will in addition to all the procedures for the Hall will have the Caries lesions treated with 30% Silver Diamine Fluoride (SDF) before cementation of the stainless-steel crowns. |
|
| Conventional Technique (CT) | Device | Prior to each restoration, a bacterial sample of the lesion will be obtained with a cotton swab and dispensed in a transport medium for microbial analyses. Conventional occlusal, proximal slicing and when necessary buccal and lingual surfaces will be carried out under local anesthesia and dental dam isolation local anesthesia.The PMC will be trimmed and crimped at the gingival margin to improve the fit, and cemented with Ketac cem. |

| Number of participants occlusal contact of the molars as assessed by the strip test | Measured by passing a strip between the contra-lateral upper and lower posterior natural teeth with the child biting into maximum intercuspation. If the strip passes without resistance between teeth anterior or posterior to the SSC there is no occlusal contact. | 6 months post intervention |
