CALCIUM HYDROXIDE AS INTRACANAL MEDICAMENT:-
A medicament is an antimicrobial agent that is placed inside the root canal between treatment appointments in an attempt to destroy remaining microorganisms and prevent reinfection (Weine 2004). Thus, they may be utilized to kill bacteria, reduce inflammation (and thereby reduce pain), help eliminate apical exudate, control inflammatory root resorption and prevent contamination between appointments. When intracanal medicaments were not used between appointments, bacterial numbers increased rapidly (Bystrom & Sundqvist 1981).
