To conduct a preliminary clinical and radiographic evaluation of a resin-based root canal sealer used in conjunction with gutta percha. In a retrospective study on 180 patients who were seen for root canal therapy, a total of 295 root canals were treated with laterally condensed gutta-percha cones in conjunction with a methacrylate-based endodontic sealer (EndoRez). Root canal therapy had been carried out in one visit using standardized techniques. The results were assessed clinically and radiographically 14-24 months postoperatively and a comparison to baseline radiographs was made. 145 patient records were available for a follow-up examination. Success of root canal treatment was based on absence of clinical symptoms, a normal or slightly widened periodontal ligament and reduction of periapical radiolucencies with an absence of pain in patients that had pre-existing lesions associated with pain. The overall success rate was 913%. Root canals had been adequately filled to the working length in 110 teeth (75.7%), short from the working length in six cases (4.1%) and flush in 19 teeth (13.1%). Extruded sealer occurred in 10 (6.9%) instances. 49 teeth out of 55 (89.1%) that had preoperative apical radiolucencies revealed partial ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
