Abstract Aim: to assess the postoperative agony and bacterial decrease following root trench treatment in teeth with necrotic mash utilizing calcium hydroxide, calcium hydroxide blended in with chlorohexidine and nanoparticles calcium hydroxide as intracanal drug. Techniques: 80 male or female patients of 25-50years old with asymptomatic uniradicular necrotic teeth were chosen and haphazardly allocated into four gatherings as per the intra-trench prescription utilized: no dressing gatherings (control bunch), calcium hydroxide bunch (CH) with saline, calcium hydroxide with chlorhexidiene, nano particles calcium hydroxide. After separation, access hole was performed trailed by chemo-mechanical planning utilizing Fanta rotating records and ordinary water system protcol then intra-waterway medicine was set by lentulo winding in the main treatment meeting. While in the second meeting following 7 days, the intracanal medicine were eliminated and channel were obturated. Postoperative agony was evaluated at 4, 24, 48 hours and following 7 days postoperatively utilizing NRS. Bacteriological examples got from the root channels previously (S1) and after instrumentation (S2) in the primary treatment meeting. In this manner, bacterial decrease was surveyed in the second meeting following 7 days (S3) utilizing province shaping unit test. Results: All intracanal medicaments brought about a measurably huge lessening in mean torment esteem from 4 hours to 7 days postoperatively. While, when contrasting all gatherings, nano particles calcium hydroxide showed the most un-present employable agony contrasted on others gatherings and no genuinely huge distinction. A genuinely critical bacterial tally decrease from S1 TO S2 and from S2 to S3. Nano particles calcium hydroxide accomplished critical bacterial check decrease contrasted with others gatherings. |
