Correct answer: C — To avoid mechanical pulp exposure while relying on a well-sealed restoration to arrest remaining caries
Selective caries removal to soft dentin (formerly 'incomplete/partial caries removal') in deep cavities aims to avoid mechanical pulp exposure while placing a well-sealed restoration that cuts off the carious biofilm from its nutrient supply. Under a properly sealed restoration, the remaining softened dentin undergoes remineralisation and the bacterial count decreases dramatically. This is supported by strong evidence from systematic reviews showing no increased risk of pulp complications compared to complete caries removal, with significantly reduced pulp exposure rates.
