  8. pH Stability of Calcium Hydroxide Preparations in a Simulated Acidic Environment

    Background Calcium hydroxide (Ca(OH)₂) is a widely used intracanal medicament in endodontics, prized for its high pH, which provides antibacterial effects and promotes healing. However, its efficacy is challenged by the acidic pH of purulent exudates in infected root canals. This study aimed to …
