Objective.
To evaluate if physical and mechanical properties of self-curing calcium hydroxide cements were affected by contact with polyacrylic and phosphoric acids.
Materials and Methods.
Resin-containing (Life (LF)) and resin-free (Hydro C (HyC)) materials were subjected to polyacrylic acid conditioning and rinsing (POL); phosphoric acid conditioning and rinsing (PHO); rinsing only; and no treatment (n=10).
Water sorption/solubility, release of hydroxyl ions (pH), roughness (Ra), and impact resistance were evaluated.
Additional samples (n=1) were prepared for scanning electron microscopy (SEM) analysis of the surface morphology.
Data were analyzed by two-way ANOVA and Tukey post hoc test (P<0.05).
Results.
Water sorption was significantly higher for LF when in contact with PHO and lower for POL (P<0.05).
The mean solubility was higher with POL for both cements (P<0.05).
PHO increased the mean surface roughness for HyC (P<0.01); a significant decrease was noted for LF after contact with both acids (P<0.01).
PHO promoted lower release of hydroxyl ions on both cements (P<0.05).
For LF, rinsing, PHO, and POL presented similar morphology, differing from the control group.
For HyC, PHO and POL presented similar morphology, differing from the control group.
Conclusions.
PHO had a negative effect on the physical properties of the cements tested, except for the solubility test.
POL affected roughness and solubility of HyC cement.
Clinical Relevance.
Clinical procedures that require polyacrylic and phosphoric acid conditioning must be done carefully on self-curing calcium hydroxide cements in order to avoid negative impact on their properties.
