E2 Dental Excavator 1.5 mm, Double-Ended Spoon for Caries Removal and Cavity Preparation

The E2 dental excavator 1.5 mm carries the same shank geometry as the E1 – 9 mm blade length and 15° blade-to-handle angle – with the blade width increased from 1.2 mm to 1.5 mm. In practical terms this means the cutting arc of the E2 spoon contacts a larger surface area of the preparation floor and walls per stroke, which is the correct selection for cavity preparations of moderate width where the E1’s smaller blade would require a greater number of passes to completely clear the softened dentin from all surfaces.

The E2 is the more commonly reached instrument on a standard restorative tray when no pulp proximity concern is present. Most routine Class I posterior cavity preparations, moderate-sized Class II preparations before bur refinement of the proximal box, and primary tooth excavations where the pulp chamber is large but not immediately at risk are cases where the 1.5 mm E2 provides the right balance between blade coverage and tactile control. The instrument removes softened dentin efficiently while the spoon’s inherent design – contacting only material at the blade curvature, not engaging hard dentin with the same sweeping force – provides the tactile feedback needed to judge when the excavation has reached the transition from soft carious tissue to hard sound dentin.

The [15-9-15] formula confirms the blade width at 1.5 mm (first digit 15, representing tenths of a millimetre), 9 mm blade length, and 15° blade angle. Both ends carry 1.5 mm mirror-image spoons. Medical-grade stainless steel, corrosion resistant, autoclavable. Keep blades sharp for accurate tactile feedback during caries excavation.

• Product Features

  • E2 dental excavator 1.5 mm wider spoon covers more preparation floor area per stroke than E1, suited to moderate cavities without pulp proximity concerns
  • Formula [15-9-15]: 1.5 mm blade width, 9 mm blade length, 15° blade-to-handle angle – same shank geometry as E1
  • Reduces total stroke count for complete caries removal in medium-sized Class I and Class II preparations
  • Double-ended mirror-image spoons cover both wall access angles from one instrument
  • Step down to E1 when approaching pulp or working in a very small confined cavity
  • Medical-grade stainless steel, corrosion resistant, fully autoclavable; maintain blade sharpness for accurate tactile feedback
