Necrotic Pulp with Symptomatic Apical Periodontitis, Postoperative Dental Pain, Antimicrobial Effect
Conditions
Brief summary
The main rational behind intracanal medicament is to kill the bacteria inside the root canal and to avert reinfection. In absence of nutrients, the bacteria remains after obturation in root canal may not survive. Otherwise they may flourish & If the root canal is not dressed properly with antiseptic medicaments between the visits, the residual bacteria may increase . Thus the use of effective intracanal medication for disinfection of root canal is necessitated . Medicament with long effect and least irritated to periradicular tissue has to be introduced to infiltrate the dentinal tubule eliminating bacteria . As the effect of intracanal medicaments is longer than irrigants, it is generally recommended to fill the root canal between appointments with intracanal medicaments. Calcium hydroxide is the most commonly recommended antimicrobial agent for interappointment medications. It serves as an effective intracanal medicament due to its alkaline pH, which inhibits bacterial growth. However, calcium hydroxide has limitations. .Recently selenium(Se) was introduced as intracanal medication .Se is a mineral essential for the formation of the amino acid selenocysteine, which is directly involved in the maintenance of the immune response. Selenium has been widely used in the medical field in the treatment of cancer, as an activator of bone metabolism, and as a stimulator of the immune system. In this study, it will show that the incorporation of Se, whether as intracanal medication alone or in conjunction with other medications, may potentiate periapical tissue repair after RCS cleaning and shaping procedures. This study consists of 60 patients divided into 3 group each group having 20 patient. Intervention 1: intracanal medication using selenium alone . Intervention 2: intracanal medication using selenium with calcium hydroxide

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Post-operative pain | 6 hours up to 96 hours | Numerical rate scale (NRS) for measuring post-operative pain after 6 hours upto 96 hours 0-10 scale , with zero meaning ''no pain '' and 10 meaning ''the worst pain imaginable '' |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Bacterial Load | Before intracanal medication injection and 2 weeks following the procedure and before obturating the root canals | Serial dilution technique For measuring bacterial load preplacement of the medication and 2 weeks postplacement . |
