Comparative Efficacy of Analgesics for Pain Relief in Patients with Symptomatic Irreversible Pulpitis Prior to Emergency Endodontic Treatment: A Randomized Controlled Trial.

Introduction: This study aimed to compare the efficacy of ibuprofen, Novafen, mefenamic acid (MA), and celecoxib for pain relief in patients with symptomatic irreversible pulpitis prior to emergency endodontic treatment.

Materials And Methods: This clinical trial was conducted on 120 patients with moderate to severe pain due to symptomatic irreversible pulpitis seeking emergency endodontic treatment. The patients were randomly divided into 4 groups to receive Novafen, MA, Celecoxib, and ibuprofen.

SARS-CoV-2-associated gut microbiome alteration; A new contributor to colorectal cancer pathogenesis.

The emergence of a novel coronavirus, COVID-19, in December 2019 led to a global pandemic with more than 170 million confirmed infections and more than 6 million deaths (by July 2022). Studies have shown that infection with SARS-CoV-2 in cancer patients has a higher mortality rate than in people without cancer. Here, we have reviewed the evidence showing that gut microbiota plays an important role in health and is linked to colorectal cancer development.

Measurement of Copper ion Extrusion from the Apex of Human Teeth with Single Canals Following of Electrophoresis.

Objective: Preventing bacterial overgrowth is an essential component of successful root canal treatment. Increasing the penetration of antimicrobial substances into the canal through electrophoresis is one of the possible methods. This study aimed to measure the copper ions extruding from the root apex after using an electrophoresis device (Depotphorese®) in human teeth with single canals.

Effect of photodynamic therapy on microleakage of class V composite restorations in primary teeth.

Background: Photodynamic therapy (PDT) is a treatment by which, light sensitive chemicals are activated at a specific wavelength, generating reactive oxygen species which can be antimicrobial and assist in disinfection. However, the oxygen radicals may interfere with the bonding process. The purpose of this study was to assess the effect of PDT with different photosensitizers on microleakage of composite restorations.
