One day after the cavity preparation, the histological analysis of the dental pulp showed mild PMN inflammatory infiltrate and a column-shaped odontoblastic layer that surrounded the usual connective tissue elements of the pulp (Figure 1).
Many studies have demonstrated that water cooling is required to reduce the increase in pulpal temperature and improve the ablation rate during cavity preparation; this is to avoid odontoblastic alterations and inflammatory response in the pulp chamber beneath the preparation.
