What do systematic reviews say?

Selective carious tissue removal (selective excavation, SE) vs Hall Technique (sealing with a preformed metal crown)

It is very uncertain whether selective carious tissue removal (selective excavation, SE) changes failure of therapy compared with hall Technique (sealing with a preformed metal crown) (very low certainty).

Non-selective carious tissue removal and conventional restoration (CR) vs Hall Technique (sealing with a preformed metal crown)

Non-selective carious tissue removal and conventional restoration (CR) may leads to higher failure of therapy compared with hall Technique (sealing with a preformed metal crown) (low certainty).
