Endodontics is a unique branch in dentistry that often deals with endodontic emergencies. In the course of this COVID-19 pandemic, Emergency Root Canal Treatment is often needed to treat symptomatic irreversible pulpitis with or without space infections. Since dental practitioners cannot often maintain a safe interpersonal distance of more than a meter and are exposed to saliva, blood, and other body fluids during surgical operations, they are especially vulnerable to SARS-CoV-2 infection. Furthermore, many dental procedures produce aerosol, increasing the risk of contamination spread through the breath. The aim of this paper is to provide dentists with realistic advice based on recent research that may be helpful in reducing the risk of COVID-19 spreading during clinical practice.

Robotics was successfully applied to the medical field which led to a new scope with vast areas of research; specially, robotics with dental application is relatively an untraveled area to explore. Access opening, bio mechanical preparation and obturation are the three vital steps in endodontic treatment. This procedure is time consuming and completely relies on the clinician's mastering skills which can be gained only through years of training and practice. Hence there are chances of human error in this stressful procedure. In order to improve the quality and reliability of endodontic therapy, an endodontic micro robot is built with an objective to modernize the traditional treatment, moving from a "manual act" to science-based automation. This paper will discuss the mechanical design and manufacture of endodontic micro robot and innovations involved from the traditional way endodontists root canal treatment to science and technology based system.

Long term survival of an endodontically treated tooth is always challenging as it is more prone to fracture when the full coverage restoration is delayed or is not at all given. Complicated crown and root fracture of such teeth is a cause of post endodontic failure. Re-restoring such teeth is bothersome as it depends on the location and extend of fracture line, affected tooth, and its relationship with the gingiva and alveolar crest. The following case report describes the reattachment of a fractured fragment of an endodontically treated maxillary right rst premolar using owable composite, after reinforcement with a bre post, followed by fabrication of metal ceramic crown. Key words -endodontically treated teeth, fracture re attachment, sub-gingival fracture, bre-reinforced post, supra gingival nish line.
