MARTINEZ, Alejandra Portillo; PERALTA, Marlene  and  KEIM, Liz. In vitro coronal microfiltration with four temporary filling materials in endodontic cavities. Rev. cient. cienc. salud [online]. 2019, vol.1, n.2, pp.33-43. ISSN 2664-2891.

Introduction. Nowadays, the ideal provisional filling material for teeth treated endodontically does not seem to exist since all the existing materials present some degree of marginal microfiltration. Objective.To determine the success rate measured by the degree of coronal microfiltration of 4 temporary restoration materials: Eugenol zinc oxide, Villevie, Clip Flow, Glass ionomer cement; in access cavities in endodontics in different periods of time, 15 days, 1 month and 3 months, for which an in vitro experimental study was carried out where 120 extracted teeth were used, which were divided into 4 groups according to the filling material. After the time elapsed the pieces were sectioned and the macroscopic observation was made. The amount of dye filtered inside the duct was measured in millimeters with the help of the Image J program, and in the case in which the cotton was filtered, it was considered that the duct showed contamination and was determined as treatment failure and were also classified in degrees. Results.The cement was that behaved better at 15 days and 1 month was the Clip flow, and at 3 months no cement was good. Conclusions.All temporary filling materials presented grade 5 filtration, so it is recommended to use the restorations for a specific time no longer than one month depending on the material to avoidmicrofiltration.
