Calcium hydroxide

Calcium hydroxide did not affect the cell survival rate of Enterococcus faecalis JH2-2 after protein synthesis was blocked by 100 μg/mL Chloramphenicol (HY-B0239) at pH 11.1 and 11.5^[1].

Calcium hydroxide pretreatment does not induce adaptive tolerance to higher pH calcium hydroxide stress in Enterococcus faecalis JH2-2^[1].

Calcium‑hydroxide‑derived CaNP releases hydroxide ions via component dissolution to neutralize acidic microenvironment and elevate pH. Calcium‑hydroxide‑derived CaNP induces osteogenic lineage differentiation of BMSCs, and 14‑day treatment further promotes late‑stage osteogenic differentiation and mineralization of BMSCs^[1].
Calcium hydroxide (Ca[OH]₂) (0.048-25.00 µg/mL; 3 h) does not exhibit cytotoxic effects on the RAW 264.7 mouse macrophage cell line at the evaluated concentrations^[3].
Calcium hydroxide releases hydroxyl ions that diffuse through root dentin, producing higher hydroxyl‑ion levels in the cervical region than in the apical region, and achieving full‑thickness dentin saturation after 2 to 3 weeks^[1].
Calcium hydroxide exhibits low immunostimulatory activity against the RAW 264.7 mouse macrophage cell line, as it does not significantly increase NO production at concentrations ranging from 0.048 to 12.5 µg/mL^[3].
Calcium hydroxide (6.25-25 µg/mL; 2 h pretreatment; overnight LPS stimulation) showed no anti-inflammatory potential in the RAW 264.7 mouse macrophage cell line, as it promoted increased TNF-α and IL-1α release in a dose-dependent manner^[3].
Calcium hydroxide can hydrolyze lipid A, releasing non-toxic free hydroxy fatty acids^[4].
Calcium hydroxide exerts a bactericidal effect on most endodontic pathogen-related bacteria of root canal origin, but it cannot eliminate Enterococcus faecalis within the dentinal tubules^[4].
Calcium hydroxide is unrelated to the survival and stress-induced protein synthesis of E. faecalis, but a functional proton pump is essential for survival at high pH^[4].
