AbstractIntroduction: Perforations are defined in endodontics as a pathological or iatrogenic communication between the canal space and the periodontium. It is the second cause of failure of endodontic treatment. The aim of this research is to evaluate the therapeutic success of iatrogenic perforations in endodontics of Malagasy practitioners in the Analamanga, Boeny and Atsimo Andrefana regions through a survey of 125 practitioners from May to June. 2021.Method: A descriptive retrospective cross-sectional multicenter study was developed. A simple random sampling was carried out for the choice of the Odontostomatologists surveyed and a sampling by convenience for the choice of 3 regions.Results: The study revealed that 12.6% of practitioners had a success rate > 75% during the perforation treatment. Calcium hydroxide has been the most widely used filling material by Malagasy Odontostomatologists, yet practitioners using BiodentineTM have achieved a success rate > 50%.Conclusion: The preservation of a tooth with an endodontic perforation is possible with a variable success rate depending on the filling product used Keywords: endodontic perforation, treatment, success rate
