Root canal treatment (RCT) is one of the standard dental procedures commonly done by dentist throughout the world. It involves removing infected pulp tissue from the tooth's pulp chamber and canals, cleaning and shaping of the root canals, disinfection of the hollow canal, and filling it with “gutta-percha” or root canal sealer. Nonetheless, it is found that many of the RCT procedures fail due to inadequacies like missing of root canal orifices, improper cleaning, or difficulties in locating the orifice. In most of the case, the failure of the treatment leads to persistent pain and secondary infection, which ultimately force the patient to undergo a subsequent RCT or extraction. Several clinical immersion sessions were conducted at MNR Dental College and Hospital and Malla Reddy Institute of Dental Sciences to understand the issues and problem-related to this root canal treatment. They were followed by an online questionnaire survey to gather a broader perspective of medical practitioners. After a year-long study, we were able to identify a few areas where design intervention can lead to the overall improvement of the root canal treatment and also can improve the workflow and comfort of the dentist. This research paper documents and highlights the research to find an unmet clinical need. This research project, though in its nascent stage, has shown great potential and with further research and development can lead to the development of a medical device that helps to improve the efficiency of the root canal treatment. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
