Preparation: Administration of 4% Articaine local anesthesia with epinephrine, rubber dam isolation, high-speed cavity preparation to non-carious dentin at lateral walls, and selective excavation of soft carious dentin at the pulpal floor using a manual excavator (leaving firm affected dentin). Cavity flushed with saline for 10 seconds and air-dried. Capping \& Restoration: Dia-Root Bio MTA mixed with sterile distilled water (0.225g : 0.5g powder ratio) for 30 seconds, placed over residual dentin at 3-4 mm thickness, and condensed with a moist cotton pellet. Cavity sealed immediately with glass ionomer cement base (Nova Glass) and restored with composite resin (Tetric N Ceram).

Preparation: Identical local anesthesia, rubber dam isolation, lateral wall caries excavation, and selective soft dentin excavation at the pulpal floor, saline flush, and air-drying. Capping \& Restoration: MTA Plus mixed with sterile distilled water to putty consistency, placed over residual dentin at 3-4 mm thickness, condensed with a moist cotton pellet, sealed immediately with glass ionomer base, and restored with identical composite resin.
