Global status of knowledge for prevention and emergency management of traumatic dental injuries in dental professionals: Systematic review and meta-analysis

Dental professionals are the primary care providers for traumatic dental injuries (TDI). The dental traumatology literature has a number of studies evaluating the knowledge of dental professionals from different parts of the world but its global status is unknown. Hence, the aim of this systematic review was to assess the global status of knowledge for the prevention and emergency management of TDI in dental professionals and to provide recommendations for future research.The protocol was designed as per the PRISMA guidelines and registered in PROSPERO (CRD42020192381). A broad-based search using text words and MeSH terms was performed in established databases as per a pre-defined strategy without any distinction of language and year of publication. Studies without details of the questionnaire, knowledge score, validity and reliability were excluded. Data extraction was performed, risk of bias assessment was done using the Joanna Briggs Institute's critical appraisal tool, and a meta-analysis was performed.Sixteen studies, which had been published between 2008 and 2020, were included for qualitative synthesis. Most of them were cross-sectional, used convenience sampling and evaluated knowledge for avulsion. Previous dental trauma training was undertaken by50% of the participants of five studies,50% knew about the correct approach in management of complicated crown fractures in three studies and ≤60% in four studies knew the critical time for replantation. There was insufficient level of knowledge in50% of the included studies. High risk of bias was found in three studies.The knowledge level in several areas of the world was unknown. The studies lacked uniformity in methods and well-designed questionnaires and they revealed insufficient levels of knowledge among dental professionals.
