What distinguishes polycarboxylate from eugenol-based cements?

Polycarboxylate cements are known for their excellent adhesive properties, which allow them to bond well to both enamel and dentin, providing superior retention compared to eugenol-based cements. Additionally, unlike eugenol, which often has sedative effects on the pulp due to the presence of eugenol oil, polycarboxylate does not sedate the pulp. This characteristic makes polycarboxylate cements a preferable choice for certain clinical situations where maintaining pulp vitality is crucial.

While ease of mixing, cost, and usage duration are important factors when comparing dental cements, the key distinguishing feature lies in the retention capabilities and the impact on dental pulp health. Polycarboxylate’s ability to provide strong retention without the sedative effects that can accompany eugenol makes it particularly valuable in restorative dentistry, where the health of the pulp is paramount.
