Lesson 1Interappointment medication and dressing (calcium hydroxide): indications and protocolsThis lesson explains reasons for between-visit medicines, focusing on calcium hydroxide paste. It covers placing methods, contact duration, dressing types, temp seals, and steps for redo or ongoing leaks in local care.
