🔵 Excavation in the vicinity of the pulp. 🔵
In order to guarantee conservative excavations preserving as much hard dental substance as possible, a clinical difference between two layers of dentin had to be made up to now: an outer, infected layer of dentin (which cannot be remineralised and has to be removed) and a carious inner dentin layer (which can be remineralised and should be preserved). We know now that there is no clearly defined border between the two layers, but a diffusion process is taking place forming a gradient – away from the carious lesion towards unchanged dentin with increasing mineralisation and hardness.
Within this gradient, the dentist has to correctly identify the end of the bacterial colonisation – a difficult task! This is where the PolyBur P1 comes into its own: It is capable of determining the correct extent of the excavation all by itself!
What does that actually mean? The material hardness of the PolyBur does not allow an excessive preparation. Once all soft, carious dentin has been removed, the instrument automatically blunts on hard, healthy dentin – in other words, it limits itself.
