Self-etch adhesive + acetone-based total-etch adhesive vs Total-etching 36% phosphoric acid + acetone-based total-etch adhesive

Radiological failure · Children with extensive decay involving the dental pulp in primary teeth

It is very uncertain whether self-etch adhesive + acetone-based total-etch adhesive changes radiological failure compared with total-etching 36% phosphoric acid + acetone-based total-etch adhesive (very low certainty).
