Antimicrobial Activity of Calcium Hydroxide in

Calcium hydroxide was originally introduced to the field of endodontics by Herman in 1920 as a pulp-capping agent 1 It is a white odorless powder with the formula Ca(OH) 2 and has a molecular weight of 74 08 Ca(OH) 2 has low solubility in water (about 1 2 gL-1 at 25 ℃) which decreases as the temperature rises 2 The dissociation coefficient of Ca(OH) 2 (0 17) permits a slow controlled

Mechanism of Action of Fluoride

Fluoride found in solution can also affect the dissolution rate without changing the solubility of tooth mineral As little as 0 5 mg/L in acidic solutions causes a reduction in the dissolution rate of apatite 25 This mechanism also involves absorption and/or ion exchange at the crystal surface Thus the surface may act more like FAP than HAP and have a different dissolution rate
