Evaluation of Postoperative Pain and Antimicrobial Efficacy of Selenium Versus Calcium Hydroxide As Intracanal Medication in Mandibular First Molars with Necrotic Pulp and Symptomatic Apical Periodontitis

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

Postoperative Pain in Photodynamic Therapy Using Curcumin As a Photosensitizer

In endodontics, various irrigation solutions are used to achieve antibacterial efficacy within the root canal. The antibacterial effect of curcumin-containing root canal solutions, when combined with photodynamic therapy, has been demonstrated in several studies. However, no research has specifically examined their effect on postoperative pain. The aim of this study is to investigate the impact of using a curcumin solution in combination with photodynamic therapy as the final irrigation solution on postoperative pain.

Effect of Different Root Canal Sealers on Postoperative Pain

This randomized clinical study aims to compare postoperative pain in patients after root canal treatments using different root canal filling materials.The root canal pastes that will be tested for postoperative pain in this study have been used worldwide for many years. Seventy-two patients with single-rooted teeth without pain symptoms but diagnosed with pulpitis and without any previous fillings or prostheses will be randomly divided into three groups according to the root canal sealers. Then the teeth in these groups will be treated with three different root canal sealers. Endodontic treatment will be performed in a single session, following standardized preparation and irrigation protocols, using the warm vertical condensation technique on all teeth. Patients will be given a Visual Analog Pain Assessment Scale and asked to mark their pain levels between 0 and 10 at 6, 24, 48, 72 hours, and 7 days after root canal treatment. Patients will be called for a check-up at the end of the 7th day, and VAS questionnaires will be collected. The investigators will be made to determine which root canal sealer causes the least pain. The null hypothesis of this study was that there would be no difference in post-procedure pain between the groups.
