Postoperative Pain and Flare-Up Rates in Diabetic Type II Patients Following The Use of Bioceramic Intracanal Medication

The goal of this randomized clinical trial is to evaluate the Postoperative Pain and Flare-Up incidence following the use of Bio-Ceramic Based Intra-Canal Medication in Diabetic type II Patients compared to the Calcium Hydroxide based Intra-canal medicament. The main questions it aims to answer are: 1. Is there any difference between using the two intracanal medicaments in the aspects of postoperative pain and flare-up incidence in diabetic type II patients? 2. Do intracanal medications reduce postoperative pain and flare-up incidence in diabetic type II patients? Participants will be divided into two groups: ( both groups will receive root canal treatment in single rooted teeth) then: First group: will receive \"Calcium Hydroxide based\" intracanal medicament Second group: will receive \"Bio-Ceramic Based\" intracanal medicament Postoperative pain will be assessed using: * visual analog scale (VAS), A scale from (0 to 10) where \"0\" means no pain and \"10\" means a severe pain that has never faced before. * Patients will be contacted by phone at 6, 12, 24, 48, 72 hours and 7 days after the first visit to collect the postoperative pain data. Flare-up is assessed: - by asking the patient to notify the investigator if any sudden severe pain or swelling takes place.
