Tooth Retention After Root Canal Treatment With Endomethasone N

Endomethasone N is a powder intended to be mixed extemporaneously with a eugenol-based liquid (i.e, Endomethasone Liquid) to obtain a permanent root canal sealer. After selection of dentists, they will screen consecutively and systematically eligible patients, will send them the Patient Information Letter and will enroll them in the clinical investigation if non opposition from the patient. Patient clinical data will be recorded in an electronic Case Report Form. Pseudonymized retro-alveolar radiographies at baseline consultation and at 5 and 10 years post-obturation consultations will be recorded in the e-CRF. These radiographies will be examined by 2 independent endodontists and the results of these examinations will be recorded in the e-CRF. Site data will be collected on a Site Questionnaire with Visual Analog Scales.
