What do systematic reviews say?

Preformed metal crown (fitted using the Hall Technique) vs Preformed metal crown (fitted using a conventional technique)

The review found no eligible studies for this question.

• Preformed crowns for decayed primary molar teeth 2015 · Cochrane All outcomes
  None of the included studies compared the effectiveness or safety of the Hall Technique versus the conventional technique of fitting a crown. No RCT evidence found.

Hall technique vs Non-restorative cavity control (NRCC)

• Interventions for treating cavitated or dentine carious lesions 2021 · Cochrane All outcomes

  Primary dentition
  Cost-effectiveness reported narratively: HT found more cost-effective than NRCC in primary teeth (Santamaria 2018); not GRADE-rated.

Hall technique vs Non-restorative cavity control (NRCC)

It is very uncertain whether hall Technique (sealing with a preformed metal crown) changes failure of therapy compared with non-restorative cavity control (NRCC) (very low certainty).
