Correct answer: D — It avoids the need for local anaesthesia, caries removal, and tooth preparation

The Hall technique involves cementation of a preformed stainless-steel crown directly over a carious primary molar without local anaesthesia, caries removal, or tooth preparation. The SSC seals the carious lesion, depriving the biofilm of substrate, and arrests caries progression. Evidence from RCTs (Innes et al.) shows outcomes equivalent to conventional restorations. It is well-accepted by children and parents due to its minimally invasive, atraumatic nature. It is indicated for primary molars without signs of irreversible pulpitis.
