Journal ArticleDOI
The role of matrix metalloproteinases in the oral environment.
TL;DR: A review of matrix metalloproteinases (MMPs) and their role in physiological and pathological extracellular matrix (ECM) remodeling and degradation processes in the oral environment is presented in this paper.
Journal ArticleDOI
pH-cycling models for in vitro evaluation of the efficacy of fluoridated dentifrices for caries control: strengths and limitations.
Marília Afonso Rabelo Buzalaf,A. R. Hannas,Ana Carolina Magalhães,Daniela Rios,Heitor Marques Honório,Alberto Carlos Botazzo Delbem +5 more
TL;DR: This critical review of literature showed that the currently available pH-cycling models are appropriate to detect dose-response and pH-response of fluoride dentifrices, and to evaluate the impact of new active principles on the effect of fluoridated dentifrice, as well as their association with other anti-caries treatments.
Journal ArticleDOI
Chlorhexidine and green tea extract reduce dentin erosion and abrasion in situ.
Ana Carolina Magalhães,Annette Wiegand,Daniela Rios,A. R. Hannas,Thomas Attin,Marília Afonso Rabelo Buzalaf +5 more
TL;DR: The possible MMP-inhibitors tested in this study seem to be a promising preventive measure to reduce dentin erosion-abrasion, but their mechanism of action needs to be investigated in further studies.
Journal ArticleDOI
Impact of Protease Inhibitors on Dentin Matrix Degradation by Collagenase
Melissa Thiemi Kato,Aline de Lima Leite,A. R. Hannas,Marcela Pagani Calabria,Ana Carolina Magalhães,José Carlos Pereira,Marília Afonso Rabelo Buzalaf +6 more
TL;DR: The results strongly suggest that the preventive effects of the PI tested against dentin erosion are due to their ability to reduce the degradation of the DOM.
Journal ArticleDOI
Gels Containing MMP Inhibitors Prevent Dental Erosion in situ
TL;DR: The use of gels delivering MMP inhibitors was shown to prevent erosion and opens a new perspective for protection against dental erosion.
