Birthplace: Brazil

Graduated in Dentistry from the University of Ribeirão Preto (2018), with a Master's degree in Restorative Dentistry (Endodontics) from the School of Dentistry of Ribeirão Preto at the University of São Paulo (FORP-USP, 2022), where she was a CAPES scholarship holder. She also holds a specialization in Endodontics from the Dental Foundation of Ribeirão Preto, affiliated with the University of São Paulo (FUNORP-USP). Currently, she is a PhD candidate in Restorative Dentistry (Endodontics) at FORP-USP, supported by a FAPESP scholarship, and is undertaking a sandwich program at the University of Illinois Chicago College of Dentistry (UIC COD). Her research interests include the effects of head and neck radiotherapy on dentin substrate, as well as the influence of dentin biomodifiers on bond strength, adhesive interface degradation, and adhesive procedures in endodontically treated teeth.

Abstract
The objective of the present study will be to evaluate the effect of carbodiimide (EDC), chitosan and proanthocyanin on the adhesive interface of fiberglass posts luted with etch-and-rinse resin cement - RelyX ARC in teeth submitted to radiotherapy in relation to: the longevity of enzymatic activity of radicular dentin, the bond strength by push-out test, the failure pattern occurred afte…

Abstract
Abstract Part A: The aim of this study is to investigate the chemical changes in root dentin resulting from ionizing radiation and their impact on interaction with conventional resin cement. Eighty single-rooted teeth were randomly divided into two groups (n=40): non-irradiated and irradiated. Root lengths were standardized, and canals were prepared and filled. Post spaces were then prepa…
