Lesson 1Interappointment medication and dressing (calcium hydroxide): indications and protocolsThis lesson covers reasons for between-visit meds, focusing on calcium hydroxide. It includes placement steps, contact duration, dressing types, temporary seals, and protocols for retreatment or ongoing leaks.
